AMS PSR

On behalf of The Ministry of Justice we are looking for a Senior Platform Engineer (Inside IR35) for a 12 month contract. Remote working with occasional travel to London.

The Ministry of Justice (MoJ) priorities include improving public safety and reducing reoffending by reforming prisons, probation and youth justice, and building a justice system which makes access to justice swifter and more certain for all citizens whatever their background. Project professionals in the MoJ help to improve the government’s ability to protect the public and reduce reoffending, and to provide a more effective, transparent and responsive criminal justice system for victims and the public.

As a Senior Platform Engineer you will be responsible for building cloud infrastructure, architecting complex systems and developing scalable code. This is an essential role for the unit as we scale several products across the justice system. As a Platform Engineer, you will have an outsized impact on staff across probation, prisons, and courts. You’ll work closely with product teams, designers, and domain experts to ship reliable systems that improve outcomes for users- while ensuring performance, security, and maintainability.

We value curiosity, pragmatism, and the ability to work in ambiguity. If you don’t meet all of the experience below, don’t worry- we’re looking for people who can learn quickly on the job and adapt to a rapidly evolving landscape.

Essential:

• Experience building and managing production infrastructure on Azure.
• Strong knowledge and hands-on experience with Terraform for infrastructure-as-code.
• Familiarity with modern web application stacks, especially Next.js, FastAPI, and PostgreSQL.
• Solid understanding of containerisation, CI/CD pipelines and secure deployment practices.
• Experience implementing logging, monitoring, and alerting for production systems.
• Understanding of LLMOps concepts and patterns- e.g. orchestration of language model pipelines, caching, logging, prompt versioning.
• Knowledge of security best practices in a cloud environment.

Desirable:

• Experience deploying or managing large language models (e.g. OpenAI, Azure OpenAI, Hugging Face) and managing cost, performance, and latency trade-offs.
• Familiarity with MLOps tooling (e.g. MLflow, Weights & Biases) and deployment of ML/AI workloads.
• Proficiency in scripting and automation using tools like Bash and Python.
• Previous experience in fast-paced product teams or startup-style environments.

Please be aware that this role can only be worked within the UK and not Overseas.
