The Role
Reporting to the Engineering Lead, you will drive the design of our core lending platform. We are looking for an engineer who understands modern, high-performance Python—not just scripting. You will architect event-driven systems, handle asynchronous workflows, and mentor the team on scalability best practices.
Tech Stack
- Core: Modern Python, AsyncIO, REST APIs.
- Data: SQL (PostgreSQL), NoSQL, Event-Driven Architecture.
- Ops: Containerisation (Docker), CI/CD, Cloud Native.
Core Responsibilities
- Architecture & Scale: Design scalable, asynchronous backend systems. You will make high-level decisions on concurrency, latency, and caching.
- Technical Leadership: Lead the team on performance tuning and reliability patterns (retries, idempotency).
- Code Quality: Enforce a high standard of testing (Unit, Integration, Contract) and modern dependency management.
- Mentorship: Mentor junior engineers through pairing and code reviews to drive technical growth within the team.
Requirements
- Deep Python Expertise: You know the internals of the language, specifically memory management, packaging, and performance tuning.
- Distributed Systems: Proven experience designing systems that handle high load and asynchronous processing.
- Methodology: Extensive experience in Agile environments (SAFe experience is a strong plus).
- Communication: Our ethos is one of continuous improvement, driven by a highly collaborative environment. While there is plenty of deep work involved, this isn’t a solitary role—we prioritise pairing, design discussions, and shared problem-solving over working in isolation.
Please note, this is a Hybrid role requiring 1-2 days per week in the office in Cardiff. We are unable to offer VISA sponsorship for this role, all applicants must have full UK right to work.
