• You’ll work with other teams across the company on a wide range of projects, ranging from end-user-facing features to behind-the-scenes improvements to our bookings, payments, and notifications platforms
  
• You’ll help implement and refine best practices for deploying, monitoring, alerting, and performance testing critical services

What you will need to be successful in this role

• Extensive experience in software development working as a Backend Engineer
  
• Strong expertise in Ruby and RSpec (or similar) and an interest in other languages (e.g. Golang, Elixir)

Job Description

Our Purpose

Improbable is dedicated to building powerful technology designed to help solve previously impossible problems and enable the creation of new realities. In gaming and entertainment, Improbable unlocks truly next-generation gameplay through virtual worlds of unprecedented scale, persistence and richness. In other industries, we hope to help answer critical questions through simulations that could lead to a better functioning world.

Our platform, SpatialOS, lets developers transcend the limits of regular computation, allowing swarms of servers running in the cloud to cooperate in order to simulate worlds far larger and more complex than any single server could.

We are a British technology company proudly building a diverse workforce, driven by a shared desire to improve and achieve extraordinary things. We’re crafting technology for the future and fostering a problem-solving culture that embraces innovation through iteration and experimentation.

Your Mission

Engineering is at the heart of Improbable. We solve some of the hardest problems around in areas such as distributed systems, high-performance cloud computing, messaging and much more.

We are technology neutral and believe in well-tested, robust code. Much of our platform is built in GoLang/Java with areas of C++, TypeScript and C#. We use Open Source technologies (such as CoreOS, etcd, Fleet, Docker, Prometheus, gRPC) and give back to the community through open source contributions when we can.

We’re hiring Senior Software Engineers across multiple teams. There is always a diverse range of challenging and interesting projects to work on. Similarly, we welcome diverse engineering backgrounds and are able to offer highly interesting challenges across all our teams, we never hire to fill a gap.

You can find out more about some of our engineering projects here

Responsibilities

• Designing and implementing new algorithms to distribute and scale our simulations
• Integrating new workers with our distributed stack
• Core infrastructure that underpins seamless scaling (networking, packing, storage, containers, logging, security across all compute providers)
• Creation of world-class, robust APIs and SDKs for external customers
• Developing tooling to understand, visualise and reason about large real-time simulations
  

Competencies

• A strong software engineering pedigree, comfortable choosing the most appropriate language/technologies for the project at hand.
• You have previously operated in a senior capacity and mentored or coached more junior engineers from a technical perspective.
• Software Engineering is more than just a job to you. Perhaps you contribute to Open Source projects, blog or speak at events occasionally, or just spend a great deal of your time thinking about interesting problems.
• You're disappointed when you're not learning something new or stretching yourself.
• You can offer your opinion and respectfully reason with people, but equally commit to the direction decided by the majority after being heard.
• You value working in different problem areas and are prepared to work in whichever team is necessary to add the most value to the business.
• You embrace that in a fast-growing start-up, priorities can change quickly.
• You're accountable and get satisfaction from shipping stuff on time / delivering quantifiable results.
• You go out of your way to help others achieve and improve as a team.
• You're modest when the results speak for themselves, and humble enough to take responsibility when they don't.

Experience Of The Following Would Be Advantageous

• Building large-scale distributed systems
• Working on cloud-based scalable architectures
• Building high-traffic, robust APIs, SDK or web architectures
• Working with Game Engines (i.e. Unity, Unreal, CryEngine etc…)

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.
