Platform Software Engineer

The things we care most about are the ones 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.

Specifically:

You can take a vague requirement, interrogate it, record the decision and its trade-offs, and define the test that would prove it wrong

Y ou 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.

Bachelor's degree in software engineering or a related discipline, or equivalent experience

These are the technologies you will be working with day to day:

AI coding tools (e.g. GitHub Copilot, Claude Code, Cursor) as the primary development workflow

AWS today, with Azure and Google Cloud planned

Infrastructure as code: AWS CDK and CloudFormation

CI/CD with CircleCI and internal developer tooling

Docker and production image pipelines

Deployment tooling for Windows and Linux, including desktop installer and packaging

Apache Solr, ZooKeeper, DB2, SQL Server, Postgres

Ansible for configuration management

Python

Kubernetes

AWS or Azure certification in one or more disciplines

FastAPI, React, or TypeScript, for internal developer tooling and portals
