Quant Engineer

Job Description

[c. £175-250k Comp Package | Hybrid Working]

We’re working with a major life and investment specialist undergoing significant modernisation across its quant platforms. This opportunity sits at the heart of their Trading Services, Risk, and Data Engineering function - building the core services that underpin pricing, booking, lifecycle management, and real-time risk across both asset and liability sides of the business. It’s a hands-on, full-stack engineering role for someone who thrives in high-ownership environments, shipping production-grade code daily, and collaborating closely with front-office and operational teams...

Key Responsibilities

• Build and maintain performant services supporting core trading and risk platforms - from lifecycle management to valuation and analytics
• Design and develop database models and optimise queries across large-scale Postgres and ClickHouse environments
• Deliver robust Python- and Rust-based microservices (HTTP/gRPC), ensuring clear interfaces and test coverage
• Build UIs in React to expose key front- and back-office functionality in real time
• Collaborate with strats, traders, and operations teams to develop clean, resilient systems that solve business-critical problems
• Deploy changes rapidly and responsibly using Kubernetes, Flux, and IaC tools like Terraform on AWS infrastructure
• Own your code in production: test thoroughly, iterate quickly, and support rollouts with pride and precision
• Contribute to a strong engineering culture where delivery velocity, system accuracy, and peer accountability are valued above all else

What You Bring…

• 5-8 years’ experience as a software or quant engineer within financial services or high-performance systems environments
• Strong Python programming skills with production experience - ideally supporting financial, risk, or trade lifecycle systems
• Experience developing microservices and APIs in Python and/or Rust (or a keen interest in learning the latter)
• Familiarity with database architecture and performance optimisation - particularly in Postgres or ClickHouse
• Confidence in unit and integration testing, with a clear focus on robustness and reliability
• Familiarity with infrastructure tools like Kubernetes, Terraform, Flux, and AWS-native services
• Experience building React-based UIs or full-stack systems
• Excellent communication skills and ability to work across business teams and technical stakeholders
• (Preferred) Prior work in capital markets or actuarial trading platforms, particularly those involving risk, pricing, or lifecycle management
• (Preferred) Exposure to gRPC, event-driven architecture, or systems that scale across distributed compute
• (Preferred) Background in building business logic into services used across risk, trading, and operations teams
