on a full-time, permanent, remote basis with a monthly requirement of attending the i2 Group offices in Cambridge.
The Platform team solves of the harder problems in software delivery: getting the same product to work correctly on a developer's laptop, a cloud cluster, a multi-node on-premise deployment, and a fully air-gapped system. None of those environments are we control deployed, and loose intent produces different results on each of them. The job is deciding precisely what has to be true everywhere, and then building it.
Alongside customer-facing delivery, the team builds the internal platform capabilities that let our R&D teams self-serve infrastructure and software. It is our second priority and the area where our AI-first workflows have moved fastest.
We are a small team, working closely with Architects, UX Designers, and Product Managers. We are looking for engineers who can define, design, and build platform capabilities, rather than simply maintain them.
We are AI-first. The bottleneck has shifted from writing to thinking, the AI writes the code, you own the decisions that shape it. If you have worked this way before, you'll recognise the workflow immediately. If you haven't, it's a shift in how you think about your time. Your focus is on the decisions, not the code that expresses them.Deep expertise in a specific tool stack matters less than it did. What counts is knowing what good looks like — enough domain awareness to write a meaningful spec, ask the right questions, and develop an instinct for where AI helps, where it misleads, and when not to trust it.
Whether you come from an AI-first background or a platform engineering background, you are welcome here. The AI-first developer brings rigour and reasoning; the platform engineer brings domain knowledge and an instinct for what good looks like. Either way, we'll help you get there.
The precision described above is not a separate activity from delivery — it is how we deliver
Building production-grade container images and the interfaces they expose to hosting platforms
Owning the deployment and upgrade story for stateful distributed components, including recovery paths from shapes already shipped to customers
Delivering releases to customers across diverse and often restricted environments, and supporting the upgrade paths from what is already in the field
Developing internal platform capabilities that let R&D teams self-serve infrastructure and software
Maintaining and improving CI/CD pipelines and internal developer tooling
Instrumenting deployments and the delivery pipeline so that decisions are made on data
Contributing to architectural decisions, validating that what gets built matches what was specified, and owning the quality of AI-generated output
Owning the testing strategy for deployments
The things we care most about are the that are hardest to teach: a spec-first way of working, design thinking, and the judgement to know when something that looks right is not
You can decompose a system into components with clear responsibilities, decide where a boundary belongs, and be concrete about what crosses it and how it is authenticated
You are AI-first or ready to commit to it — not just willing to try it alongside your existing workflow
Cloud deployment and Infrastructure-as-Code — you have built deployments on a major cloud and understand the tooling
You have the judgement to recognise when AI output is wrong — a plausible implementation that quietly violates a security invariant, or a port that looks correct and is not
You are comfortable working in technologies and deployment topologies you have not encountered before, and you learn them quickly
The technical depth we look for sits alongside those traits, not above them. We want experience in platform or software engineering in a commercial environment — enough exposure to deployment and operational concerns to write meaningful specs and validate AI output against them:
Experience shipping software to structurally different deployment targets; you understand why they differ, not just that they do
Container technology: you have built and shipped production-grade images, not just run them locally
Cloud deployment and Infrastructure-as-Code: you have worked with AWS and understand the tooling
Application security: you understand trust boundaries, identity models, and secrets handling
CI/CD pipelines: you have built and maintained them, not just consumed them
You can work effectively with engineers, architects, and non-technical stakeholders
The role may require UK national Security Check (SC) vetting;
candidates must be eligible for and willing to undergo this if needed.
These are the technologies you will be working with day to day:
Kubernetes
AWS or Azure certification in or more disciplines
FastAPI, React, or TypeScript, for internal developer tooling and portals
