Job Description

Quant Engineering Lead (Python / LLM Tooling)



The mandate:


Our client—a global, multi-asset investment manager—has rolled out cutting-edge large-language-model coding assistants across its Risk & Portfolio-Tech organisation. They now need a senior engineer who can turn “moon-shot” ideas into production tools, guiding the business on what LLMs can really do and delivering rapid-fire prototypes that become mission-critical apps.


What you’ll tackle


  • Spot the pain-points across Equities, Credit, Rates and central Risk teams; translate data-flow headaches into buildable tech projects.
  • Prototype at pace in Python—leveraging LLM co-pilots—to stand-up analytics services, REST APIs and lightweight Dash/React front-ends.
  • Own the full stack: data ingestion (SQL, files, feeds), business logic, web/UI, CI pipelines and Linux deployment.
  • Codify best practice for safe, auditable LLM-assisted development; lead code reviews and knowledge-share sessions.
  • Stay user-facing—white-board with quants, ask clarifying questions, iterate live and keep comms flowing.


You in a nutshell


  • 5 + years building production-grade Python systems for data-heavy businesses; comfortable with tests, version control and optimisation.
  • Confident SQL, exposure to REST and messaging (Rabbit, Kafka, etc.), and enough Linux to troubleshoot on the command line.
  • UI chops in Dash, Flask or React to whip up proof-of-concept dashboards.
  • Solid grounding in financial products & risk metrics—equities, bonds and derivatives; VaR, stress, PnL explain.
  • Excellent communicator who never “goes dark”, loves prototyping and isn’t afraid to ask the awkward question.
  • A self-starter ready to jump into the deep end and push tech (and yourself) beyond comfort zones.


Bonus points for: prior hands-on with Copilot / CodeWhisperer, AWS data tooling, containerisation and a history of mentoring juniors.


Why join?

You’ll become the go-to explorer for one of the buy-side’s most ambitious data-tech stacks—turning previously impossible ideas into daily reality and watching users’ eyes light up when the numbers land in seconds, not hours.
