Product Engineer, Applied AI

Duties and Accountabilities

• Assess prototypes for production readiness, including architecture, code quality, dependencies, data handling, security, scalability, supportability and user value. Recommend whether each prototype should be hardened, refactored, rebuilt or stopped, and agree a practical route to production.

• Build Python services, relational data models, APIs and background processing; add lightweight frontend interfaces where useful.

• Develop MCP integrations through the Firm’s gateway, handling authentication, permissions and token exchange with downstream applications.

• Work with Technology on approved cloud deployments and connections to on-premises systems, resolving infrastructure and integration dependencies.

• Follow the Firm’s central SDLC and security policies; implement testing, access controls, audit logging and secure secrets handling.

• Take production applications through deployment, controlled release and early live use, then establish clear ownership, support procedures, service expectations and handover arrangements with the relevant Technology teams.

• Define and run evaluations for AI-enabled behaviour, including representative test cases, quality thresholds, regression testing and human review where appropriate. Monitor failures, latency, usage and consumption costs in production, and use the results to improve applications and contribute reusable engineering patterns as the team grows.

Required Skills

• Professional software engineering experience that includes taking incomplete, experimental or early-stage applications into production and maintaining them afterwards.

• Experience working in an autonomous, fast-moving environment where you contributed across development, integration, deployment and live operation.

• Strong Python skills and experience with FastAPI or comparable Python frameworks.

• Strong SQL and relational database skills, plus experience designing and integrating APIs.

• Practical understanding of authentication and authorisation, including OAuth 2.0 or OpenID Connect.

• Experience with automated testing, Git, CI/CD, cloud deployment and production troubleshooting.

• Clear communication, pragmatic product and engineering judgement, and the ability to bring structure to unfamiliar or incomplete systems. You should be comfortable making progress with limited documentation, surfacing risks early and working with security, infrastructure and product specialists to resolve them.

Preferred Experience

Experience with FastMCP, Azure, Entra ID, API gateways, delegated access or token exchange would be valuable. Other useful experience includes cloud-to-on-premises integration, LLM applications and straightforward JavaScript/TypeScript interfaces. You do not need experience with every technology listed or a legal background.
