Principal Engineer
Location: Newbury (hybrid — reactive dependent on workload)
£90,000 + bonus + healthcare
About the Role
We're looking for a Principal Engineer to act as technical authority and right hand to our Head of Engineering. This is a hands-on, individual-contributor role (not people management) for someone who's operated at Principal or Staff level, stays close to the code, and enjoys untangling genuinely hard, messy problems.
You'll work on complex, distributed, real-time systems that process high volumes of live data and make time-critical decisions.
What You'll Do
- Own the whole-system technical picture, from data ingestion through processing to the end-user experience
- Make the cross-cutting architectural and technical calls, and own the outcomes
- Set and uphold engineering standards across the team
- Help lead the organisation's adoption of AI-assisted / agentic development practices
- Take on the hardest cross-boundary problems: major integrations, technology choices, build-vs-buy decisions
- Stay hands-on, prototyping, spiking, debugging, and reviewing code alongside the team
- Support and unblock a strong team of engineers without formal management authority — leading through technical credibility
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What We're Looking For
- Proven experience operating as a senior technical authority on complex, distributed systems — architecture you've designed that has shipped and survived contact with production
- Strong background in distributed systems, messaging/event-driven architectures, microservices, and containerised deployments
- Experience working on systems with a hardware or physical-world component (e.g. sensor integration, embedded interfaces, or similar) is a strong plus
- Comfortable reasoning across an entire technology stack, from low-level data sources through to operator-facing tools
- A track record of being the person others bring their hardest problems to
- Excellent communication skills — able to influence technical direction without formal authority
- Eligibility to obtain government security clearance is required for this role
