Why this job matters
IT has become the core asset for most businesses. Our Cloud Native engineers guide our clients through this increasingly complex IT landscape.
We build confidence with cloud technologies and help clients transition to modern architecture. Our engineers also work with Cloud Native vendors on next-generation open-source tools.
What we look for
Why apply
Youāll be in charge of shaping a new IT architecture for some of the best companies in the world. We work in small, self-managed teams that take full responsibility for the projects. Weāre not tech/cloud service resellers. We mix the best open-source tools and services that make sense for the project. We move fast and deliver mainly short-term projects (2-4 months), mostly working from our offices. We automate the infrastructure of our customers and deploy orchestration layers on top of it to run apps and data.
All our engineers are encouraged to share their knowledge at conferences and within the company. We consider ourselves a continuous learning company. There are no rockstars here, just people that wanna grow themselves and their community. Switching between projects/roles/offices is possible and quite common.

Utility Warehouse is an award winning multi-utility provider, our core offering is simple: all your utilities, one monthly bill. Our network of 45,000 partners add the human touch to our delivery, help us get the word out to our existing members and bring in new ones. We consistently win the Which? awards for our service and donāt believe āgood enoughā exists when it comes to customer satisfaction.
Weāve got the culture and focus of the earliest stage startups with the resources and strength of an extremely profitable and loved brand. Our eyes are on meteoric growth over the next few years. All the pieces to make it happen are here, we need you to help us put them together.
Our philosophy revolves around getting things done and we only hire people we can trust to do that. Bring your A game and youāll always get ours. If youāre the type that can deliver youāll be rewarded with small, fully autonomous teams that have real ownership of their products using a cutting edge stack in a best-idea-wins meritocracy. If that doesnāt quite cut it, we can throw in flexible and remote working (no, really) with top of market compensation.
As for the tech we use: the best tool is the right tool. Go and React are our bread and butter but nothing is stopping you from reaching for something else if it does it better. We deploy to Kubernetes across both AWS and GCP with some help from Terraform. We run a mature event sourced microservice architecture using Kafka, NATS and GRPC. As much as is possible we code in the open on GitHub. If it can be open- sourced, it shall. If we can submit a PR instead of building our own, we will. Getting your hands dirty from the top to the bottom of the stack isnāt a promise to be broken, itās a requirement. If youāre only good at parts of it thatās okay, weāll quickly make you good at all of it.

Distributed Systems Engineer - to help us build a public, decentralised, blockchain-backed legal agreements network
London
Ā£40,000 - Ā£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 companyās 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 otherās 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 āaround the softwareā; 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:

In general Verisart seeks engineers interested in applying cryptography at real world problems. Our problem lies within the art market as we address the problem of proving provenance for artworks and building evidence based certificates of authenticity. We recognize that cryptography is not a magic bullet. We want to use it intelligently to provide evidence where possible for people to interpret, like the web of trust. Weāre looking for people who understand how to apply cryptography to problems. While understanding the mathematical backgrounds to cryptography is great, itās not essential if you understand how the cryptographic primitives like hashing and message signing work together to solve real problems. We value passion and hard work when tackling challenges and above all else although an interest in arts and collectibles is helpful.

Code for Humans
Your machine is happy if it compiles; your team is happy if they can understand what it does. Your pull requests are succinct and a pleasure to review, you have unit tests where it matters, and you understand that the code is not, in fact, the documentation.
Reliable & Resilient Software Not for you the happy path or the assumed network. That habit of yours of assuming the worst and planning for it has earned your stripes in the world of running software at scale under real-world conditions.
Tools for the Team
Whether it's a smart command line utility or a core internal library, you excel at improving everyone's lives by removing repetition & common sources of error, and by solving hard problems in accessible ways. 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.
We are an equal opportunity employer and value diversity in our company. We do not discriminate on the basis of race, religion, colour, national origin, gender, sexual orientation, age, marital status, or disability status.

We are here to help our customers build delightful applications. By solving significant engineering challenges and packaging them into easy to use APIs, we let developers focus on making their users happy.
We put emphasis on collaboration between people and teams. Everyone is on the same mission, so sharing work helps us reach our goals faster. Throwing problems over the wall and pointing fingers at each other is not our style.
We strive for transparency. Keeping everyone well-informed is crucial for building trust, efficiency and satisfaction at work.

Our mission is to give every person on the planet fast and affordable internet. We remove traditional internet infrastructure costs by developing technology which allows any device to be used as a cloud server. Using this tech, we will build a global distributed cloud platform. We are working at the forefront of distributed systems, peer-to-peer networking, and cloud systems.
Flareās first product is a peer-to-peer CDN, designed to be faster and cheaper than incumbents. We are looking for someone to help us tackle the scalability challenges around our product. You will help us design and build out our caching, messaging, and routing systems to work across millions of nodes. You will have significant input and control over the architecture of these systems, to help us ensure that they are scalable, reliable, and fast.
We raised a Ā£1.1m seed round earlier this year, and are backed by some of the original investors of Protocol Labs, Transferwise, and Zoopla. We have already partnered with industry heavyweights like the Guardian Media Group (one of the largest media platforms in the world), and our advisory board includes the ex-CEO of BitTorrent, ex-CTO of Shazam, and one of Akamaiās founding architects.
You will be a core team member in a fast-moving startup, working alongside talented engineers to build and ship a product that will be used by millions. You will be one of the first employees at Flare, and you will have direct input over the architecture and design of Flareās systems. It is an unparalleled opportunity to grow and learn in a startup environment, and have direct impact on Flareās direction.
We are looking for someone who has built and deployed performant and distributed systems at scale (preferably in Golang). We expect that you have experience working with the major cloud providers (AWS/GCP), ideally in high-load systems. You should be familiar with CDN architectures (caches, origin servers, proxies, etc), the networking stack, and the infrastructure of the internet.
