Overview

Principal Recruitment Consultant - Software Engineering

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.

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.
