Distributed Systems Engineer - to help us build a public, decentralised, blockchain-backed legal agreements network
London
£40,000 - £80,000 plus options (ESOP).
Relocation package available for the right candidate. This role could also be based in our Edinburgh office.
Candidates currently based outside of London or Edinburgh must indicate their preferred location and willingness to relocate in their cover letter.
We are looking for kind, talented software engineers to help us make smart iterations on our legal agreements network as we deploy successive test networks.
Monax were pioneers of permissioned blockchains and smart contracts and we are building our Agreements Network to allow new and more efficient forms of legal transacting.
Exploiting the benefits of various decentralised, distributed, and masterless technologies - chiefly Hyperledger Burrow, which Monax built from scratch and still maintains based on the Tendermint consensus engine.
You will have the chance to work on a system that has distributed consensus and validation in a low trust environment at its heart and offers very interesting challenges, these could be:
Working with our CTO on our Node Distribution Team you can expect to quickly own significant parts of our stack, and make decisions that will affect the company’s future viability in a fast-moving space (public permissioned consensus networks). You would also work closely with our Product Team who are responsible for building the foundational smart contracts, the business process modelling engine that drives the Agreements Network and also our particular front end (the network is open to extension by any of our co-founders however).
Your role will give you the chance to work across all teams in the business and it will also give you the opportunity to leave your mark in a growing industry, where you need to evaluate existing best practices and apply them to new technological paradigms and new programming languages. Navigating between the hype, the detractors and the zealots we believe there is real value in our approach and we intend to prove it.
You will join a business building a genuinely novel system, that in part intends to create an entirely new market by enabling legal products that challenge existing legal services.
This role would suit a talented software engineer, with solid technical skills in and a minimum of 3-4 years of software development experience. We are also open to engineers who can bring significantly more experience to the role. If you are a good match for Monax, we are willing to create a role that suits you.
Who do we need? Someone who has:
It is crucial that you are able to take part in forceful yet respectful technical discussions with colleagues and that you are able to change your mind about something if required, and also are able to change other’s minds.
Real things you might work on:
What can Monax offer you?
Extremely marketable blockchain and cryptocurrency skills.
The chance to make blockchain systems live up to their hype by making them highly operable, our network will be operated peer-to-peer by many parties and this needs to be as painless as possible.
Experience in blending distributed, decentralised, and centralised systems. To spend time working on something foundational at the level of a network architecture.
The chance to spend time thinking ‘around the software’; about law, economics, and game theory.
You will have a high level of autonomy. The business has just enough hierarchy, consensus and individual project responsibility (c.f. design-by-committee) favoured over diktats.
Flexible working - the successful candidate will be based in our London or Edinburgh work space primarily, but there is scope for flexible working and choosing your own hours and place of work when established.
Relocation assistance is available for the right candidate.
Who will you be working with?
Around fifteen people in our passionate cross functional team, including time with:

At Monzo we’re aiming to build the best current account in the world. We are always keen to hear from capable, creative engineers who want to help us accomplish that goal. We want our bank to be safe and secure for our customers, so security is very important to us
Security at Monzo
Monzo’s security team has a wide range of responsibilities, from infrastructure security to application security. As a bank, we are solving diverse, novel problems to ensure that our customers are safe and secure.
One of the guiding principles of security at Monzo is that security at the expense of user experience is a last resort. We aim to move mountains in the background such that we can build world-class features without compromising on security.
As a member of our security team you would be responsible for constantly improving the security of Monzo, and you would work closely with other teams to ensure that our systems are secure by design. Of course, security incidents can and do occur, and the security team is involved with many different types of incident response.
Our engineers have a variety of different backgrounds
We have several non-graduates; only some of us studied Computer Science; one of the team has a degree in Marketing; some of us have worked in huge companies; some have only ever worked in startups; others are former consultants. As long as you enjoy learning new things, we’d love to talk to you.
We encourage an open and transparent working environment
You can get involved in any aspect of the business you are interested in and, following Stripe’s example, all emails in the company are visible in an email archive. We regularly run hackathons in which people build things on our third party API and we contribute to open source software as much as possible. We’ve also made our product roadmap public and give sneak peeks of features in our community forum. Our blog is a good place to learn even more about what we do!You can get involved in any aspect of the business you are interested in and, following Stripe’s example, all emails in the company are visible in an email archive.
