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:

Rumble brings together the best of IT, security and networking technology to deliver amazing network discovery and asset inventory capabilities for modern enterprises.
An accurate network inventory is a fundamental building block of all security programs, yet most inventory products do a poor job of network-based discovery because they only see it as a stepping stone to the “real” product features. Legacy products work by sending sensitive credentials to every asset on the network and fail to handle today’s hybrid environments. Without a solid inventory, most companies struggle with attack surface reduction, network management, and incident response.
Rumble Network Discovery is a product of Rumble, Inc. We are a fully virtual, high-growth startup based in the United States. Our founders each have over 20 years of experience growing companies in the information security industry, including Rapid7, Veracode, BreakingPoint Systems, and PGP.
Rumble has already proven its market fit. Rumble appeals to companies of all shapes and sizes; we have customers that range from museums to Fortune 500 technology companies. We serve the low-end of the market through eCommerce and the mid-market and enterprise segment through inside sales.
We’re building the engineering team to lead Rumble into the future. Our work is a mix of Go development, low-level protocol research, standard web technologies, PostgreSQL, and a mix of cloud technologies and integrations. Our platform is cloud-agnostic, can be self-hosted, and builds from a single repository. We ship daily and focus on incremental delivery with fast turnaround for customer requests and bug fixes. We bootstrapped to product market fit and recently raised a $5m venture capital round to accelerate our growth. The company was cash-flow positive in 2020.
We’re looking for senior engineers that are excited about research-driven product development and want to help build a company focused on happy customers and product-led growth.
We’re searching for senior engineers to grow our team! You will contribute to all stages of development, deployment, support, operations, and product planning. This position reports directly to the CEO today and will split into functional teams once the team expands. This is a growth opportunity for future engineering leadership as well as long-term individual contributors.
Contribute your skills and knowledge to building, supporting, and operating an amazing product experience for our customers.
Learn as you go to understand customer needs, product structure, fingerprinting techniques, and network protocols.
Self-task and coordinate with the rest of the engineering team to move the product forward, solve customer challenges, and keep the platform running smoothly.
Work with customers to identify bugs, understand gaps in product functionality, and flag opportunities for improvement.
Work closely and communicate effectively with functional teams across the company to keep our customer experience aligned with product and sales operations.
A strong track record of building products that customers love.
5+ years of experience in programming-heavy engineering roles with a demonstrated ability to ship quality results, frequently.
Go programming experience is preferred, but if you have deep experience in other languages and are excited about learning Go, we can make that work too.
Extensive experience with web development (HTML, CSS, plain JS) and a solid understanding of the HTTP protocol and the web browser security model.
PostgreSQL database experience, but other SQL database experience is also applicable.
A solid understanding of standard development tools and processes, including Git and issue-management systems.
Confidence working with Linux instances for deployment and diagnostics.
We’re a fully remote company but you need to be located in the US, with US citizenship or permanent residency for healthcare, payroll, and legal reasons.
We offer an extensive set of benefits including:
Competitive salaries and a stock option plan.
Top of the line medical, dental, vision, life and disability coverages with Rumble paying for 99% of the premium.
A flexible vacation policy.
401(k) match program.
To apply for this role, please send your resume and information about the products you have worked on to careers@rumble.run.
We encourage under-represented applicants to apply, even if you don’t think you fit 100% of the criteria (nobody ever does)!

We’re passionate about putting Organise members first – we believe change at work happens when more people get involved.
We're expanding our team and building out our platform to include a peer-to-peer network. We're building a space for people to build power and support each other at work pseudonymously.

Using Organise, Amazon drivers landed national media coverage, including an exclusive BBC Newsnight investigation, exposing their working conditions & calling on Amazon CEO to lower their parcel targets back to a safe level. They’ve also met directly with MPs and got the Amazon CEO grilled in front of Parliament. 40% of drivers have had their targets lowered to a safer level now as a result - a huge win for their collective action.
Over 100,000 members pressured the government to abandon their plans to scrap the laws protecting paid holidays and rest breaks (working time directive) - including sending tens of thousands of messages sent directly to the Business Secretary in the 24 hours leading up to the U-turn. Civil servants tell us (off the record) that the department were ‘astonished’ by the level of public backlash to the plans.
Dan*, a Census worker, started a campaign when he noticed Census temporary workers were being asked to travel to attend their first-day induction without being offered to have their travel expenses covered. In response to thousands of people joining the campaign, ONS has agreed to make sure all temporary workers are reimbursed for their travel expenses. With this and the update to the Census Jobs FAQs page clarifying the expenses policy, Census workers can start their jobs without being out of pocket.
