Join a high-impact engineering team building the systems that power trading, risk and analytics at a fast-growing, tech-driven fund. You’ll work close to the action with quants and traders, helping to rebuild critical platforms away from legacy constraints and into a modern, cloud-native stack.
About the team
This tech team develops and enhances systems used across the front-office trading, operations and finance functions. You’ll work side-by-side with Strats (quant analysts), traders, operations and finance to design, build and support the applications that keep the business running smoothly. Led by a highly technical leadership team with top-tier trading and market-making backgrounds, the group sets a high engineering bar but offers strong collaboration, learning and ownership. There is also a dedicated internal “quest”-style engineering group focused on continuously improving core infrastructure, tooling and developer experience, so you’ll be part of an environment that takes engineering quality seriously.
What you’ll do
- You’ll work on a mix of greenfield and existing systems, with scope aligned to your level:
- Enhance and support business-critical applications across the firm, including:
- Feed processing systems
- Trade processing and booking
- Graphical user interfaces used by traders and operations
- Workflow and automation tools
- Finance and risk reporting systems
- Design, develop and deploy new applications and integrations using Python and related technologies in a hybrid cloud environment (AWS/Azure).
- Build and integrate services with external platforms and key origination/servicing systems.
- Collaborate with Operations, Pricing, Trading and Finance to gather requirements and deliver robust, well-tested features.
At junior–mid level (c. 3+ years):
- Take ownership of well-defined components and features.
- Work closely with senior engineers for design reviews, mentorship and best-practice guidance.
- Grow your exposure to system design, cloud-native patterns and production support.
At senior level:
- Lead design and implementation of larger features and services, from requirements through to production.
- Influence architecture decisions as systems are migrated off legacy platforms and rebuilt using modern tooling.
- Help improve engineering practices (testing, CI/CD, observability, infra-as-code) and mentor less experienced developers.
Skills and experience
- Required
- 3+ years of application development experience, ideally within investment banking, insurance or another complex, data-heavy environment.
- Strong Python programming experience.
- Ability to work with multiple programming languages and technologies as needed.
- Familiarity with the software development lifecycle, infrastructure-as-code concepts and modern development best practices.
- Experience building or operating cloud-native systems (e.g. AWS).
- Excellent communication skills and a collaborative, team-oriented mindset.
- Desirable
- Server-side web development experience (including modern web frameworks).
- Familiarity with SQL Server and/or PostgreSQL.
- Experience with React / JavaScript UI development.
- Linux experience and comfort working in a command-line-driven environment.
Why this role
- Work close to trading and quant teams, with your code directly impacting real-world decisions and risk.
- Help drive a strategic migration away from legacy systems into a modern, cloud-native architecture using technologies like Kubernetes and infrastructure-as-code.
- Join a high-quality engineering culture with strong technical leadership, clear impact, and opportunities to grow into broader ownership or leadership roles over time.
- Inclusive, collaborative environment that values different perspectives and actively encourages applications from under-represented groups in technology.
