Luno is a leading global cryptocurrency company operating across more than 40 countries and with offices in London, Singapore and Cape Town. We’re a profitable, growing company with over 2 million customers, and are backed by some of the top tech investors in the world.
Our products and services make it safe and easy for people and businesses to buy, store and learn about cryptocurrencies like Bitcoin and Ethereum. Our vision is to upgrade the world to a better financial system.
To the moon! 🚀
We have multiple openings for senior software engineers in our brand new London office. These are in a range of teams including fraud, platform, payments, shield, onboarding, and crypto-security. 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.
We succeed as a team. Our teams are split into pods, each of which focuses on a specific aspect of our product. Any engineer is able to deploy to production, and we deploy multiple times each day. 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.

As a Go backend engineer, you’ll work on our API servers and internal libraries that make the Vizzlo products come to live. Your code will talk to AWS storage infrastructure, to JavaScript frontends, and best of all, to lots of different third-party APIs of other products Vizzlo integrates with. You are passionate about idiomatic Go code but are not afraid to tackle obstacles from all kinds of points of view when necessary. You love to write reliable, scalable, and tested code.
We are looking for a full time Backend Software Engineer to join our development team. Job duties will include working on Stream's core API technology as well as designing and building high-performance software.

You will have an enormous impact on making our API service faster, more scalable and more flexible.
You will add new features to the service and find ways to make the existing ones perform orders of magnitude faster. Our customers have millions of users; they use Stream for mission critical features such as showing content and exposing core functionality of their application. Building stable and reliable software is not just an option: as a member of the development team, you will design and write state-of-the-art software, follow best practices, measure everything and be responsible for deployment to production. You will also spend part of your time talking to our customers and help them to use Stream in their app.
The challenges * Distributed databases: we built our own data store for feeds and for chat * Real-time messaging * High performance: our API responses are in the 10ms range * High scalability: we use sharding, master-master, and master-slave to ensure scalability * High availability: our entire infrastructure is designed and operated to survive entire datacenter crashes * Multi-region: we deploy our service on 4 different continents
