With over 40 engineers based in our Cape Town office, you’ll be joining a group of highly motivated experienced developers who you’ll work collaboratively with across our currency exchange, fraud, payments and compliance pods.
As a small company operating on a global scale, you’ll immediately see how your contributions directly impact both our internal users and client experience. We make decisions based on facts, not fiction. Many of the problems we’re solving result in genuinely trail blazing solutions which can’t be found on StackOverflow; so we’re looking for an experienced engineer that thrives on working in a complex domain.
We use Go, microservices architecture (gRPC) and AWS, but if you come from a Java, Python or other relevant language we’ll help you get up to speed with our comprehensive engineering onboarding program.

Your pod will include a product owner, back end engineers, Android and iOS developers, and web developers who each bring a unique perspective to the problem you’re all solving.
This is a fantastic opportunity to learn more about cryptocurrencies, blockchain, emerging and developed markets, and scaling a global business. We provide great benefits and the autonomy to conceive and execute your own projects. Best of all you get to work with a diverse team of talented, ambitious and friendly people on something that will truly revolutionise the world.
As a “Newnaut” we’ll fly you to Cape Town to meet the wider team, and go through our comprehensive onboarding program. We expect you to have a passion for blockchain and cryptocurrencies but we understand that this is a new industry so we’ll help you learn about how the blockchain works and understand all aspects of our business.
Building a new financial system for the world requires a special breed of people working together with unusual skill, focus and determination. “Moontality” represents the ten core principles that underpin everything we do, setting us apart from the rest.
As an experienced lead-level or senior engineer, you’ll have:
Don’t be put off if you don’t tick all of the boxes – they’re a guide based on what we’d love to see but we appreciate that great software engineers have diverse backgrounds.
