They're now looking for a Principal Python Engineer to take ownership of platform architecture and set the technical direction for the teams delivering it. This is a hands-on leadership role. You'll be shaping how systems are built, not just reviewing how others build them.

- Drive engineering standards across CI/CD, branching strategy, release automation, and operational excellence
- Collaborate with cross-functional teams across the UK, Ireland, and Europe on trading, monitoring, and optimisation platforms
- Mentor engineers at all levels, support graduate onboarding, and shape long-term engineering culture
The Stack
- Python, FastAPI, GraphQL (Strawberry), Kafka MSK, MQTT, REST APIs, Redshift, SQL, AWS (EC2, ECS, ECR, RDS, IoT Core, IAM, MSK), Docker, Linux, Bitbucket, CI/CD pipelines, trunk-based development.
What You'll Bring
- 6+ years of commercial software engineering experience, ideally with some client-facing delivery exposure
- Deep, production-grade Python expertise
- PCEP or PCAP certification is a bonus, not a barrier
- Proven experience designing event-driven systems, microservices, and high-throughput data platforms
- A track record of technical leadership through mentoring and guiding early-career engineers
- Sector exposure to energy markets, trading systems, or financial services is a genuine advantage
What's On Offer
- Competitive salary plus options
