We’re hiring Python Engineers to join a front office-facing platform build within a tier-one financial services organisation - this is a greenfield platform in a high-growth area of the business, focused on scaling core trading workflows, data, and automation across multiple teams.
The role involves working on a backend-heavy platform that underpins pricing, workflows, and trade data across the business. The system is being rolled out more broadly, with a focus on improving visibility, reducing manual processes, and creating a single, scalable solution. The work is strongly focused on Python and system design, building production-grade services rather than lightweight scripting.
What you’ll be doing:
- Building and evolving backend services in Python within a distributed system
- Working on data-intensive workflows and messaging-driven architectures
- Contributing to a platform designed as a single source of truth across teams
- Automating manual processes and enabling faster product and workflow rollout
- Collaborating closely with engineers and front office users
Tech environment:
- Python (core focus), some Java and React (experience not essential)
- Messaging systems and distributed architectures
- MongoDB (core data store), some Oracle
What we’re looking for:
- Strong Python backend engineering experience in production environments
- Experience building and operating complex, business-critical systems
- Solid understanding of system design, data flows, and distributed systems
- Comfortable working in evolving platforms with multiple stakeholders
- Financial services experience is helpful but not required if candidates can show a genuine interest and conceptual understanding
Location: Hybrid working (London-based, with 3 days in office required)
Contract type: Permanent or contract (inside IR35) options available
