[Full-time] Communications Lead at Sovereign Tech Agency

2026-07-09 11:19:01

Location: Berlin, Germany
URL: https://www.sovereign.tech/jobs/communications-lead

Description:

We are looking for an experienced, strategic thinker to lead and develop our communications work.

Who we are

The Sovereign Tech Agency is an organization dedicated to the digital sovereignty of the economy and society. Our mission is to strengthen the foundations of our digital autonomy and secure open digital technologies as the critical infrastructure of the 21st century.

Open digital infrastructure is the backbone of the digital world. It is essential for the flow of information, for government, for business, and for innovation, much like roads and bridges in the physical world. The most effective strategy for building this infrastructure is open source software: it is the bedrock on which our digital society is built – powerful, collaborative, and democratic.

With a commission from the German Federal Ministry for Digital Transformation and Government Modernisation, we invest in critical software components, develop programs, and create structures that sustainably strengthen the open source ecosystem, including the people behind the code.

Our work is unique: we are leading the way on how governments engage with open digital infrastructure and laying the groundwork for how modern societies ensure resilience, technological diversity, and public digital services.

Together, we are building Europe’s digital future – open, secure, and sovereign.

Who we are looking for

We are looking for a communications lead to contribute to the future growth of the Sovereign Tech Agency.

The Sovereign Tech Agency operates at the intersection of open source technology, digital infrastructure, and policy — in Germany, Europe, and beyond.

How do we ensure that these foundational technologies remain open, secure, and sustainable?

This position is for someone who understands that communications is not a support function but a strategic lever for shaping technology, innovation, and digital policy. In this role, you will shape how the Sovereign Tech Agency is understood and perceived and ensure our issues are visible, politically relevant, and land effectively with the right audiences. In day-to-day operations, you will turn our content, programs, and strategic initiatives into clear and compelling communications that resonate with policymakers, media, industry, and open source communities. You will help shape key debates on digital infrastructure, open source, technological sovereignty, and public sector digitalization in Germany and throughout Europe.

You are the primary contact for all external communications and will partner closely with the leadership team to shape how the organization is understood and perceived. The role offers significant room to shape things in a growing public interest organization.

You will define the organization’s overall communications direction and ensure our messaging is consistent and resonant across all audiences and contexts.

Developing and sharpening an overarching narrative, grounded in our mission, strategy, and portfolio
Turning complex issues into clear, politically effective messaging
Developing and refining our positioning with political, business, and other societal stakeholders
Ensuring consistent communications across all channels
Preparing leadership for public appearances, talks, and panels — developing the content, messaging, and strategic framing behind briefings, talking points, and presentations

Communications Delivery & Development

You will take responsibility for the day-to-day operations and the longer-term development of our communications work.

Planning and executing communications around announcements, calls, milestones, and the conclusion of cycles and cohorts: for example, UN Open Source Week, the Digital Commons EDIC, as well as the Sovereign Tech Fund, the Sovereign Tech Fellowship, Sovereign Tech Resilience, and Sovereign Tech Standards
Running the Sovereign Tech Agency’s owned channels: website, newsletter, blog, social media, press, and publications
Continuing to develop our website as the central hub for our programs, content, publications, and public presence
Prioritizing and coordinating ongoing communications activities across all channels and workstreams
Building and maintaining a productive communications pipeline: clear formats, repeatable processes, a consistent editorial line
Ensuring key developments and issues are communicated clearly and accessibly within the organization
Leading and developing the communications team

Proactive Communications & Outreach

You will ensure the organization’s key issues get seen — at the right moment, in the right form, by the right people.

Identifying communications opportunities and issues with political or wider relevance for the Sovereign Tech Agency and its leadership
Proactively placing stories and materials with appropriate media outlets
Building and maintaining relationships with journalists, editors, and key voices and networks
Developing communications outputs that generate consistent visibility and resonance

Your Qualities

Professional Qualifications

A university degree (e.g. in communications, marketing, business with a focus on marketing or communications) or equivalent professional experience in a senior role in strategic communications, public affairs, journalism, or a comparable field
Experience in political, public, or regulated environments (e.g. ministries, trade associations, think tanks, foundations, or tech and digital policy)
Experience communicating technical topics, ideally in a technology-driven or digital policy environment
A foundational understanding of open source ecosystems and issues at the intersection of technology, business, and policy — or a demonstrated ability to build that understanding quickly
Adept at conveying complex technical content clearly, precisely, and compellingly to technical and non-technical audiences alike
Experience preparing leadership for public appearances and engagements
Excellent German and English language skills, with demonstrated experience producing publication-ready copy in both languages
Our working language is English — you should be able to express yourself with confidence and precision, including in fast-paced working situations

Personal Qualities

A highly developed strategic mindset and sharp instinct for political and communications dynamics
The ability to prioritize issues and orient work toward impact
A hands-on mentality and willingness to work both conceptually and operationally
Confidence and composure when dealing with media, stakeholders, and internal partners
Discretion and professionalism when handling sensitive topics
A collaborative spirit: you value open exchange, collegial working relationships, and mutual feedback
You’re a team player and enjoy collaborating with coworkers, active and open communication, and both giving and receiving feedback.
You’re organized, self-directed, pragmatic, and proactive, and work effectively with modern collaboration tools

For us, your motivation, attitude, and vision are as important as your resume. Even if you don’t fit all requirements, we welcome your application.

What we offer

Based on experience and qualifications, the annual compensation for this role (at 40 hours per week) is 84,000 to 91,000 Euro aligned with the TVöD-Bund wage agreement for the public sector.
Flexible and remote-friendly work arrangements for all family and life situations, from our office in Berlin-Mitte or in a hybrid model * We have four in-person team meetings in or around Berlin per year; almost all meetings are scheduled during GMT +1 working hours. * Employment under German law; work and residence must be in Germany
30 days of vacation (based on a 5-day work week)
Support for your professional and personal development, including the opportunity to attend international conferences

We are looking for an experienced Android engineer to contribute to two software products from the decentralized networking team: Ceno Browser and the eQsat Extractor applications. Ceno is a tool designed for content accessibility in some of the most repressive digital regimes, with a particular focus on areas under a network shutdown. It has been operationally deployed since 2020. The Android version is built from Mozilla’s Android Components and utilizes the Ouinet library to share web content peer-to-peer over an existing Distributed Hash Table (e.g. BitTorrent). eQsat is a satellite datacasting solution built to support the injection of new web content into isolated networks. Its client-side application extracts and decodes content received from the satellite stream, thereafter making it available on the local network to users of the Ceno Browser. It’s a modern day sneakernet serving thousands of users everyday!

This is a relatively fast-paced environment with a strong sense of individual contribution and close-knit project teams. We expect individuals to grow into their roles but also to make it their own.

Your primary duties will include

Implementing UI/UX improvements in the Ceno for Android application
Driving development of new features for the eQsat Extractor application
Maintaining privacy-preserving analytics suite to improve insight into our distributed network
Unit-testing code for robustness, usability, and general reliability
Work on bug fixing and improving application performance
Maintaining the highest level of professional security and code development practices
Listening critically and giving viable feedback to team members, managers, and outside groups
Documenting work toward long-term maintenance and reproducibility
Being on time with product timelines and deliverables

You should

Have 3+ years of professional software engineering experience, with significant experience building production Android applications, (experience with mobile web browser development is a strong plus)
Have strong experience in Kotlin programming
Have experience developing JavaScript web applications
Have experience in a test-driven approach to software development & version control with git
Be reachable for at least 2 hours on working days between 9am – 5pm EST

Nice to have

Familiarity with async JavaScript/Node.js and front-end web development
Experience in network programming (HTTP TCP/IP, UDP) and decentralized/distributed networking technologies
Enjoy delving into other people’s code, debugging and improving it
Excellent development credentials and years of experience working with a variety of technologies
A strong desire to work on free and open-source software

How to apply

Please send all documents to hireme|at|equalitie|dot|org including your resume and a cover letter that also explains how your experience and motivation match our requirements. Include your Github username or another platform where we can see your previous projects. Also include links to past mobile app projects you’ve worked on. Note that selected candidates will be asked to perform a (non-project related) coding challenge.

eQualitie welcomes applicants from all backgrounds. We are a remote-first company and offer flexible working arrangements. We are keen to hear from people who consider themselves under-represented in the software, technology or FLOSS communities – even if they feel they meet only some of our needs.

[Full-time] Cryptography Engineer (SecureDrop) at Freedom of the Press Foundation

2026-05-13 13:40:38

Location: United States
URL: https://freedomofthepress.na.teamtailor.com/jobs/610227-cryptography-engineer

Description:

Position Description

Freedom of the Press Foundation (FPF), a nonprofit organization dedicated to protecting, defending, and empowering public-interest journalism, is hiring a cryptography engineer to join its SecureDrop development team. Reporting to the engineering manager for SecureDrop, this position is a unique opportunity to be part of a small, primarily remote, and internationally distributed team that is making it possible for newsrooms to manage their most sensitive submissions, from the next big story about abuse of government power to the exposure of corruption at the local level.

This position will work alongside the other five engineers on the team contributing to the project. You can learn more about our team and colleagues here. As a team, we strive to provide an equitable and collaborative environment. We have strong expectations of mutual respect, kindness, and understanding, and we build those expectations into our work through processes like blameless retrospectives. We share responsibilities for tasks like code review and release management, and support each other in learning and professional development goals.

About the Project

SecureDrop is an open source whistleblower submission system used by journalists to communicate with sources. Through its hardened architecture and the use of the Tor network, it offers whistleblowers strong security and anonymity protections. Used by more than 70 news organizations worldwide, including The New York Times, The Washington Post, The Guardian, and Al Jazeera, SecureDrop is composed of a variety of components:

SecureDrop Server: an anonymous whistleblowing system, deployed on hardened and Ansible-managed Ubuntu servers, hosting two web applications available as onion services over the Tor network.
SecureDrop Workstation: a platform built on top of Qubes OS to make SecureDrop faster and simpler for journalists to use. It consists of an Electron application and other services that span across a suite of SaltStack-provisioned, task-specific virtual machines.
SecureDrop Protocol: an end-to-end encrypted protocol designed specifically for whistleblowing systems, currently being implemented in Rust as the foundation for the next-generation SecureDrop Server.

The team is developing the next-generation SecureDrop Server, which provides end-to-end encryption while allowing for easier deployments compared with the current system. As part of the team, a successful candidate will have a key role in these efforts.

Responsibilities

Designing and specifying extensions to the SecureDrop end-to-end encryption protocol for new security properties or features (e.g., implementing abuse-resistance features).
Contributing to the formal modeling of the SecureDrop end-to-end encryption protocol.
Implementing client-side encryption for journalist and source communication.
Working with the rest of the team to integrate the protocol into the SecureDrop source and journalist workflows.
Performing code reviews for contributions from the development team and the larger SecureDrop community.
