Title: Forward Deployed Engineer

Function: Justice AI Unit

Grade: Grade 6

Summary

Our justice system faces serious challenges, from rising demand and staff shortages to siloed systems and inconsistent access. AI presents an opportunity to address these problems at scale. But this opportunity must be seized with care.

The Justice AI Unit is a small, fast-moving and innovative team. We build and ship products quickly across the Ministry of Justice. By embedding AI that enhances, not replaces, human judgement, we aim to deliver better outcomes, faster services, and greater fairness for all.

Role

As a Forward Deployed Engineer at the Justice AI Unit, you will build and deploy AI products that have real-world impact across courts, prisons, and probation services. You’ll work directly with frontline staff to understand their needs, co-develop solutions, and own the full delivery lifecycle, from problem discovery to product deployment and scale. This is a hands-on, high-agency role for engineers who want to work at pace, across the full AI and software stack, and in service of one of the most complex and vital systems in the country. Join us to transform justice through practical, responsible AI.

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.

Responsibilities:

• Develop high-impact AI products, models and agents that will be widely used across the Ministry of Justice

• Work directly in the field (e.g., courts, prisons, probation) to understand user needs, operational challenges and co-build with users.

• Own end-to-end delivery: from identifying the problem, building the product, deploying it, and scaling adoption

Essential Criteria

• Experience building and deploying AI-native software in production environments

• Experience owning all parts of the software and AI stack - frontend, backend, database, AI and ML

• Experience building solutions like predictive models, LLM workflows, scheduling algorithms, data pipelines etc.

• Ability to work and thrive in complex organisational contexts

• Up to date on the latest developments in AI

Desirable Criteria

• Experience with our stack- NextJS, FastAPI, Postgres

• Experience with LLM observability and evaluation tools like Langfuse

• Cloud and infrastructure experience - Terraform, Azure etc.

• Entrepreneurial or startup experience
