Job Description

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 multiple clusters of nodes, most of which are not under your control to handle semi-automated network upgrades and governance votes. How do you upgrade a network you do not control?
• Using cryptographic primitives like Verifiable Random Functions to orchestrate churn amongst network validators
• Build package manager and compiler integrations for deploying and testing smart contracts
• Implement low-level virtual machine instructions and improvements to our Ethereum Virtual Machine implementation

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:

• Go experience or the ability to pick it up in a few weeks
• Kubernetes experience or the ability to pick it up in a few weeks
• A degree-level qualification in a numerate discipline or equivalent evidence of analytic and reasoning skills and theoretical thinking
• A good knowledge of algorithms and data structures
• A hacker mentality towards making things work
• An ability for long form design work ‘on pencil and paper’
• An ineffable marmot-ness

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:

• Build a Kubernetes operator for Hyperledger Burrow
• Devise a way to compress/normalise data in our merkle tree to control our long-term storage usage
• Implement an atomic swap with public Ethereum to represent value on our chain
• Write optimised native (Go) functions, callable from evm, to implement graph traversal over our business processes
• Build fee allocation and distribution models that help maintain our network and provide the correct incentives

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:

• Our CTO in London, who would be your primary daily contact
• Our CPO in New York, with whom you’ll liaise with to ensure the distribution platform and product stack work harmoniously.
• Product Team members currently building the application stack.
• Our Legal Engineers in New York providing crucial context to how legal products on the platform will be used
• Our CEO in Edinburgh for just about anything else...

Company

Utility Warehouse is a FTSE 250 organisation which has established itself as the most trusted supplier of utility products in the UK. Utility Warehouse is the only genuine multi-utility operator in the market providing gas, electricity, landline, broadband, mobile & insurance products and services to households and businesses nationwide, all on one single monthly bill. With over 600,000 customers the organisation has grown through a philosophy of offering savings, simplicity and service. Customers enjoy a number of advantages, including membership of a discount club, and a unique CashBack reward system on everyday shopping. The organisation does not advertise, preferring instead to invest in customer services and to keep prices low. Utility Warehouse has predominantly grown through a network of over 45,000 partners who operate as lead generators and advocates for the organisation. These partners come from a range of personal and professional backgrounds, and actively take it upon themselves to promote and recommend Utility Warehouse to friends, families and their professional networks. Trust between these partners and the organisation is crucial, and ensures that customer service and satisfaction are consistently prioritised.

Background

Utility Warehouse is an energetic and entrepreneurial challenger in a market traditionally composed of monolithic, slow competitors. In the utilities market, it is difficult to compete on the quality of the product and therefore establishing a strong value proposition is crucial to avoid a race to the bottom on price. Utility Warehouse has established itself as the most trusted brand in its sector, winning accolades from industry publications and consumer advisory guides. Customer service is at the core of their business ethos and another way they differentiate from their competitors; 93% of customers would recommend the organisation to a friend. By establishing a best-in-class experience for the consumer, Utility Warehouse commands a strong market position in an age where technology makes it increasingly easy to access information on consumers’ experiences. The organisation is well-placed to capture an increasingly large portion of the £52bn market that they operate in. By staying true to their values of trust and service, Utility Warehouse is the only major provider in the market to be both growing and profitable.

Utility Warehouse has an adaptive, agile, fast-paced culture which has enabled it to grow rapidly. The management team has expanded over the last two years as part of the growth strategy with significant hires in technology, legal, marketing, and finance. These hires and the rebuilding of the platform will enable the company to grow to two million customers over the medium-term. Utility Warehouse operates at high-transactional scale, processing large volumes of data. This presents new opportunities to understand customer behaviours better and to create an improved customer experience as a result.

Opportunity

With ambitious product plans for the future, it is important to have a solid foundation to enable growth for the business, allow innovation and achieve rapid time to market. To realise this, the underlying platforms and systems must be designed to be flexible, modular and resilient.

You will join our Insurance team tasked with designing and building the insurance platform from the ground up to enable new opportunities to our insurance product and services.

The platform will be a set of simple and intelligent APIs built using microservices and event driven architectures. Internally, the decision and rating engines will leverage integration with numerous 3rd party systems to provide quotes, offer addons, allow policy uptake and operational management.

Key responsibilities

• Design, architect and build multi-channel platform solutions
• Contribute ideas and influence business wide solution architecture
• Build robust and scalable end-to-end software solutions
• Participate in the entire development life cycle, from requirements to delivery
• Influence other team members in a cross functional product team
• Build integrations with legacy systems with a focus on eventually moving away from them

Key requirements

• Good engineering skill with an eye for both modelling and code architecture
• Knowledge of when and how to apply test driven approaches
• Understanding of microservice/service oriented and distributed architectures
• Understanding of event source and/or event driven architectures
• Belief in agile principles and a devops culture and be familiar working in a agile enviornment

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.

Requirements

• Senior Backend Experience/Knowledge of
  
• Go, Java, Python or C
  
• AWS or GCP
  
• Docker, Linux
  
• NoSQL/Cassandra (not including Mongo & Redis)
