Our client builds software that operates at the sharp end of energy markets, trading platforms, monitoring systems, and optimisation tools running across the UK, Ireland, and Europe. The infrastructure is complex, the data volumes are serious, and the engineering standards are high. 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.
What You'll Do
- Own the design and delivery of Python microservices across AWS and on-premise environments
- Lead the architecture of large-scale data capture, processing, and transformation platforms built on event-driven principles
- 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
- Real influence over architecture, tooling, and engineering direction
- A culture built around innovation, learning, and technical craft
- High-impact exposure across multiple products and markets
