We're on a mission to give everyone on Earth an open, inclusive financial system, and we need your help.

The Zcash Company is at the forefront of the Internet Money revolution. Fueled by scientific discovery and guided by love for humanity, we are aiming to create a global, open economic fabric which will provide financial inclusion to potentially two billion unbanked people. We feel that we are part of something that is much bigger than ourselves.

Our flagship network, Zcash, launched in the fall of 2016 has quickly grown to be one of the most valued and admired cryptocurrencies/blockchains in the world.


We believe in emergent team intelligence. We think that a high functioning team is greater than the sum of its parts. We seek people who are “multipliers.” People who create a positive and supportive environment for the people around them. People who demonstrate a high degree of conscientiousness with their team members and in their work. We highly value good sense of humor, humility, selflessness, flexibility, good judgment, calmness, reliability, curiosity, strong desire for mastery, and independent thinking.

We love humble geniuses.

We care a lot about behavioral traits, talent, internal drive and experience, but only if our values and general philosophy match can we create real magic! We are looking for people who are driven by purpose. We believe that great employees are motivated by the mission, the team and challenging problems.


Table stakes: Design software that is secure, efficient, consistent, clear, reusable, and extensible.
Every line of code is a business decision. Understand the nature of the business challenge really well.
Make haste slowly: Iterate quickly and ship code frequently while maintaining the utmost in quality.
Maintain system quality using automated QA techniques during development. Write tests first. Cover all code paths. Use the test suite as specification of your code functionality.
We approach software design with “systems thinking” while keeping in mind that some of the worst failures are systems failures.
We promote seeing things from the perspective of the whole instead of collections of individual components.
The biggest pattern we follow is to reduce complexity. A prime objective of systems architecting it to simplify, simplify, simplify. Design for the simple case first.
Minimize upfront design. Only design what is necessary. Avoid considering future use cases. Write less code.
When componentizing, choose elements with low external complexity and high internal complexity. Define a clear contract for each component.
Comment the intent of the code, not what it’s doing. Comment only unobvious, complex code.
Think long term.
Write code defensively.
Siloed knowledge is bad.
Deal with problems early. Keep technical debt low. Refactor often.
Don’t optimize too early. Make code correct first, fast second.
Actively seek criticism.
A little paranoia goes a long way. As engineers, we have a saying “If engineers feel optimistic, people get hurt.” We temper this caution with self-care and care for each other.
We also find ourselves saying “if it’s worth doing once, it’s worth automating”. We like to solve problems permanently. We continuously codify the lessons learned and incorporate them into the codebase.
Build a platform, not a product. Allow others to extend your work.
The best software engineers are also natural leaders.
