Skills

We don't expect anyone to be a 10/10 in every area, and you don't need to tick every single bullet point to apply. What follows is a list of the skills and experience that we think matter most for this role. Different strengths are welcome. - Substantial experience as a principal or staff software engineer. - Demonstrable experience building developer platforms, internal tooling, and paved paths used by engineering team. - 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. - A track record of driving adoption by persuasion and good product decisions, not mandate. - Clear written communication, including documentation that engineers actually read. About you - You treat the platform as a product and your colleagues as customers, and you measure yourself on their throughput rather than your own. - You notice friction that everyone else has learned to live with, and you fix it. - You're a genuine advocate for agentic engineering. You make the case for it with evidence, help teams adopt it well, and are honest about where it isn't the right tool. - You are opinionated about tooling and you change your mind when the evidence changes. - You are comfortable owning something long-lived rather than moving between projects. - You can tell the difference between a genuinely better tool and a fashionable one. - You are honest about trade-offs, including the ones in your own work. No prior defence experience is required. We're interested in people who've built and run developer platforms in demanding environments, wherever that was.
