Principal Forward Deployed Engineer

Design, build, and productionise bespoke, higher-complexity AI solutions yourself, taking the hardest and least-defined engagements personally.

Own the architecture and design decisions for the team’s solutions, keeping them secure, scalable, and aligned to the enterprise core stack.

Take solutions through evaluation, observability, and our AI governance checkpoints, and keep them healthy afterwards.

Form part of the AI Technical Leadership Team, and build an AI Technology roadmap that lines up with the JHI strategic roadmap.

Work across the AI technology remits — AI Platforms, AI Architecture, AI Engineering, and AI Governance Implementation — owning the Forward Deployed Engineering deliverables and keeping them aligned to enterprise architecture.

Contribute to AI technology strategy, standards, and buy-versus-build, and to the investment recommendations and backlog that follow.

Review new models, tools, and vendors and determine their feasibility here, weighing cost, licensing, security, supportability, and vendor viability alongside capability, and documenting the recommendation — including the recommendation not to adopt.

Sit with business users and hold the relationship senior enough that the team is invited into problems early rather than handed finished requirements.

Partner with the AI Enablement Partners on escalated demand, and set realistic expectations with senior stakeholders.

Build advanced investment capability on Nexus, our agentic workspace, taking models and signals from one desk into a supported, firm-wide capability, and lead the build-out of citizen developer workflows through to production.

Expose data and capability through Accio, our centralised MCP server, and as skills, tools, and connectors on Nexus, building reusable components rather than one-off integrations.

Co-build enterprise core-stack deliverables with Percepta and AI Engineering, and represent Forward Deployed Engineering in architecture and design authority forums.

Must have skills

At minimum eight years in technical, business-facing engineering roles — forward deployed engineering, solutions engineering, consulting-side software engineering, or engineering embedded in a business unit — including time as the most senior engineer on the work. Former technical founders are encouraged to apply.

Experience leading engineers as a line manager, tech lead, or founder. You need not have run a large team, but you must have been accountable for other people’s delivery.

Strong Python and SQL, and a track record of shipping production applications, with hands-on delivery recent enough to still be real.

Production experience with LLMs — prompt and context engineering, agent development, evaluation, deployment at scale — including agentic capability such as MCP servers, tools, or connectors.

Experience building data pipelines from APIs and enterprise systems, and working knowledge of a major cloud, ideally Azure, with CI/CD, containers, and infrastructure as code.

Experience owning a technical roadmap, and judgement on technology selection — you can evaluate a new tool, model, or vendor, test it properly, and defend the recommendation.

Excellent stakeholder skills, credibility with senior audiences, and the ability to influence without direct authority.

High agency, genuine interest in the business problem, and willingness to move from building towards leading as the team grows.

Experience in a regulated environment where governance, compliance, and data sensitivity shape how solutions are built.

Nice to have skills

Experience standing up a new engineering team or function from scratch, including hiring and defining how it works.

Asset management or financial services domain knowledge, particularly the investment process, front office workflows, or fixed income.

Quantitative investment concepts such as fair value, relative value, signal generation, or portfolio construction.

Snowflake, Microsoft Fabric / OneLake, Azure AI Foundry, model gateways, or AI observability in production.

Vendor selection, commercial negotiation, or licensing at enterprise scale, or contributing to architecture and technology governance forums.

Supervisory responsibilities

Yes. This role line-manages Forward Deployed Engineers. There may be no direct reports on day one; the team is expected to be built out under this role, with line-management responsibility growing accordingly. Until then it carries technical leadership and delivery accountability for Forward Deployed Engineering.
