Principal Forward Deployed Data Scientist

This is a very senior, hands-on technical leadership role for a data scientist

who has built real, production AI applications for internal teams and for

customers and knows what it takes to take an idea all the way from

prototype to production within a regulated environment.

You'll sit at the intersection of our business, our users, and the bleeding

edge of AI. You won't be handed a spec you'll work directly with

stakeholders to understand the problem, choose the right approach for it,

build the solution, deploy it, and stay with it as it grows. You are the

person who turns ambiguous goals into production agentic systems that people

depend on, and who keeps us ahead of a technology landscape that changes week

to week.


WHAT YOU'LL DO

 •  Take ideas from prototype to production. Start from a rough concept or

    business problem, prove it quickly with a prototype, then do the hard

    engineering to turn it into a reliable, scalable, production-grade system

    people can depend on — and know what each stage demands.

 •  Build agentic AI, end to end. Design, implement, deploy, and evolve

    autonomous and tool-using AI systems — agents that reason, plan, call

    tools, and act on the user's behalf — for both internal and

    customer-facing use, owning the full lifecycle and the outcome.

 •  Design agentic architectures. Build agent-orchestration systems: single

    and multi-agent setups, tool and function calling, Model Context Protocol

    (MCP) and agent-to-agent coordination, planning and reasoning loops,

    memory, identity and access for agents, and the control and safety

    mechanisms that keep autonomous behaviour trustworthy.

 •  Match the solution to the problem. No one-size-fits-all. You assess each

    problem on its own terms and choose the right approach — a different

    model, agent pattern, or architecture for a different need — rather than

    forcing everything through a single template.

 •  Live on the bleeding edge. Actively track new models, agentic frameworks,

    techniques, and tooling as they emerge; prototype quickly, form a view,

    and bring the ones that matter into production with sound judgement about

    what's ready and what's hype.

 •  Deliver, dependably. Ship software to production on time and to a high

    standard, navigating the controls, governance, and compliance

    expectations of a regulated environment.

 •  Embed with the business. Work shoulder-to-shoulder with stakeholders,

    shape the roadmap, and translate business goals into working AI

    capability.

 •  Set the standard. Define how agentic AI is built here — quality,

    evaluation, observability, and responsible-AI practices that others

    follow — and be the trusted technical authority for AI delivery across

    the organisation.

ESSENTIAL (MUST-HAVE)

 •  Building AI/LLM applications in production — real systems people rely on,

    whether internal or customer-facing, not prototypes or demos.

 •  Taking ideas from prototype to production — a proven ability to move from

    a fast proof of concept to a hardened, scalable, maintainable production

    system, and the judgement to know what changes between the two.

 •  A proven track record of delivering software to production in a regulated

    environment — real, shipped systems with lasting impact, delivered within

    governance, risk, compliance, and audit controls (e.g. financial services

    or similar) without losing delivery pace.

 •  Hands-on experience with agentic AI — building systems where models

    reason, plan, call tools, and take actions, including multi-agent and

    agent-to-agent (A2A) coordination, tool and data integration via the

    Model Context Protocol (MCP), and the control and safety mechanisms that

    keep autonomous behaviour trustworthy.

 •  Identity and access for AI — how agents authenticate, act on behalf of

    users with delegated authority, and operate under non-human/service

    identities, with the authentication, authorisation, and auditability a

    regulated environment demands.

 •  Strong software engineering fundamentals — reliable, observable, testable,

    maintainable systems.

 •  Excellent communication and stakeholder skills — fluent moving between a

    business conversation and a technical design, and comfortable working

    directly with non-technical stakeholders.

 •  A forward-deployed mindset — comfortable with ambiguity, close to the

    business and the user, biased toward shipping and iterating.


STRONGLY DESIRABLE

 •  Retrieval-augmented generation (RAG) — grounding responses in trusted

    organisational knowledge.

 •  Evaluation (evals) — defining, measuring, and improving the quality and

    reliability of AI and agent behaviour.

 •  Guardrails and safety — input/output filtering, hallucination mitigation,

    control over autonomous actions, and responsible-AI practices.

 •  Prompt and context design, memory, and other techniques for shaping

    reliable model and agent behaviour.

 •  Choosing the right approach for the problem — range and judgement to

    select between different models, agent patterns, and architectures as the

    problem demands.

 •  Leading architecture across teams — setting technical direction that other

    engineers build on.

 •  An insatiable pull toward new and emerging technology — you keep up with

    the frontier because you want to, and you can tell production-ready from

    hype.


NICE TO HAVE

 •  Experience building customer-facing AI — delivering AI systems that real

    external customers interact with, and handling the extra bar for safety,

    trust, and polish that comes with it.

 •  Exposure to agent-driven and AI-generated UI — interfaces that agents

    render, drive, or adapt dynamically.
