Principal Software Engineer
Our client is a fast-growing UK engineering and software technology company located in Bristol.
They are looking to hire a Principal Software Engineer to lead the design, architecture, and development of their internal developer platform that all their engineering teams will utilize and depend on.
You will architect and own the tooling, infrastructure, workflows, and components that their developers build on.
This will be a platform built from the ground up for agentic engineering—so you will lead the implementation of agentic AI and champion its use, i.e., roll out coding agents across engineering workflows and own how and where they’re used.
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.
Key Skills/Experience Required
- Substantial experience as a principal or staff software engineer, with experience of utilizing a range of languages/tools/frameworks (Python, Go, Rust, AWS, Kubernetes, etc)
- Demonstrable experience building developer platforms, internal tooling, and paved paths used by engineering teams.
- Hands-on experience implementing agentic AI in real engineering workflows (beyond individual experimentation).
- Experience designing the guardrails around agentic AI: sandboxing, permissioning, audit logging, or observability for tools operating with elevated access.
- Deep, hands-on experience of CI/CD, infrastructure as code, containers, and Kubernetes.
- Experience of building and deploying reproducible development environments.
