Job Description

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! 🚀

Your Mission

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.

How we work

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.

A typical day

• Join the pod’s daily standup to share progress and remove blockers
• Collaborate with other engineers on the design of a new payment integration to launch to a new market
• Write clean, well-tested code that directly affects users, the company and the Bitcoin ecosystem
• Grab lunch with the company (we provide lunch Monday - Thursday)
• Coach a team member by giving feedback on their pull-request

What’s in it for you

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.

What you’ll need

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:

• A solid foundation in computer science in areas such as algorithms, data structures, and software design
• Extensive programming experience in an object-oriented language. We use Go but we welcome applicants who have strong experience in other languages like Java, Scala or C++, etc.
• Proven experience of building, shipping and supporting a product
• An interest in cryptocurrencies like Bitcoin

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.

Job Description

Resin.io provides a software platform that helps developers build, deploy and manage code on connected devices. We brought Docker to embedded GNU/Linux devices in 2013 and have been building our IoT toolkit ever since. We also maintain a variety of successful open source projects including Etcher, Balena, and resinOS, and made contributions to high-exposure projects such as Docker, Electron, and AppImage.

Our technology is open, standards-based, and proven in production across a wide range of scenarios from drones, 3D printers, point-of-sale devices, tidal turbines, skyscrapers and more. Our investors include DFJ, Aspect Ventures, GE, and Ericsson.

Resin is a highly distributed, remote-friendly company with a pretty much flat hierarchy. Our organization is adaptive, getting feedback signals from our users and systems. Right now we organize ourselves by projects, which allow us to build complex features and solve big problems, while staying mutable. As a distributed group, we rely on clear communication and the rule of "assume positive intent" to help us work together across time zones, cultures and first languages. Our base of operations is nominally London, though really we are living all over the world: from Barcelona to Bulgaria, Argentina to Vietnam, and many more.

On being a Backend Engineer at resin.io

We maintain a service infrastructure for IoT devices, and this is where we have quite a bit of our engineering talent. You will be actively working on one or more of these core components, fixing bugs, solving complex technical problems, and implementing user-facing features across the resin.io stack. While resin.io focuses on IoT, the majority of our engineers don't require embedded programming expertise.

People who are successful engineers are well-rounded generalists and great communicators. They are eager to take responsibility for a project, and are able to make good decisions about the project because they have the context of what's important.

We don't require engineers to be already familiar with the technologies we use. We are happy to invest in people that showcase a strong understanding of the challenges of building secure distributed systems.

Responsibilities

• Actively invest back in our own technology, libraries, and frameworks
• Understand security best practices and strive to apply them in your work
• Be highly motivated to produce great code
• Evaluate customer requirements and other inputs to determine the scope and timing of new functionality
• Design, architect, and own the execution of your projects
• Ensure the architecture of our distributed system remains cohesive
• Collaborate, brainstorm, and coordinate work with other resineers
• Understand the high-level goals, and thus know how to prioritize your work
• Challenge orthodoxy when that will help the product evolve
• Work efficiently with a certain amount of ambiguity in the tasks you're executing

REQUIREMENTS

Need to have:

• Desire to make yourself and others more effective. You'd be bothered by an inefficient process
• Good understanding of software engineering practices and how to apply them
• Excellent written communication skills, and fluency in English
• Self-discipline to take on a project and push it to completion without too much management. You also know when to ask for help
• Strong problem-solving abilities. You know how to split a complex problem into incremental pieces
• Basic front-end development skills

Nice to have:

• A sample of your work (URL or attached sample)
• Contributions to OSS projects (please include a URL)
• Having worked remotely before
• Experience with Resin.io as a user
• Experience with embedded GNU/Linux, anything ranging from personal projects with a Raspberry Pi to commercial or industrial scenarios with custom devices
• Experience with React, Node.js, Docker, PostgreSQL, or Kubernetes
• Experience with embedded development and microprocessors
• Experience with the Electron framework and cross-platform development
• Experience leading software projects in the open source world

Make sure to let us know if any of these items apply to you!

Perks & Benefits

• Work with an extremely talented, diverse team
• Equipment of your choice
• Remote-friendly
• Flexible working hours
• Flexible vacation policy
• Annual company gathering in an international location - this year, Barcelona in October
• We send you hardware for side projects!

You build internal processes that are so reliable they melt into the background but are key to getting work done.

APIs
You've been on the receiving end of APIs good and bad, and want to delight our customers with the high quality they expect. You know that whilst everything should be JSON, sometimes you have to get your hands dirty with some SOAP for that critical integration but know how to isolate the contagion.

Requirements

Job Description

Core platform

When we refer to the "core platform", we mean the services which underpin the processes of all insurance activities on our system.

For example, we expect one of these to be the "policy service", which might be responsible for ensuring compliant issuance of policies, coordinating mid-term adjustments, preventing overlapping policies (double insurance), etc.

Other services could include user authentication, risk & pricing calculation, handling the process of modifying user data in-line with any mid-term adjustment requirements.

All services we consider to be part of the core platform will have strict requirements around stability, data integrity and transactional safety. All functionality must fail safely and explicitly, for example using 2-phase commit processes or other similar techniques. This will also require a reasonable level of testing to validate this safety.

Requirements

The perfect addition to our team will have:

• a fiercely independent and self-driven approach
• 5+ years' commercial experience working on back-end systems at high-scale startups
• at least a year of commercial experience working with Go
• strong knowledge of security practices, ideally with a slightly grey-hat background
• a working knowledge of the entire web stack - from how DNS lookups are transmitted, to how browsers prioritize CSS rules
• awareness of compliance and financial regulation

We are a small team so it is important that the successful candidate is not only technically highly competent, but also a great cultural fit!

Perks & Benefits

As well as a competitive salary (£60-75k, dependent on experience) and equity based remuneration, benefits of working at Cuvva include working in our new offices in Shoreditch and of course significant savings on your car insurance.
