Senior Staff Engineer - Agentic

Role overview

Own the discovery, design, and delivery of agentic systems that automate operational work across multiple business and engineering teams. The role combines technical architecture with stakeholder collaboration: identify where automation is useful, shape an approach without a predefined specification, and measure whether the result is reliable and saves time.

Responsibilities

- Map how teams work and decide which processes to automate, redesign, or leave unchanged. - Turn unclear needs into architecture and delivery plans that stakeholders can understand and agent workflows can execute. - Set shared patterns for retrieval, orchestration, tool access, identity, and evaluation across agent projects. - Design in reliability and safeguards, including access controls, human review, recovery, and task state management. - Measure the impact of delivered systems and communicate when an approach is not producing the intended gains. - Develop reusable components and help teams build, review, and operate their own agents.

Requirements

- Experience defining technical problems with business stakeholders and owning delivery without relying on a detailed specification. - Track record of building and maintaining production agentic systems, including multi-agent systems and MCP servers used in real work. - Strong retrieval-augmented generation experience, including selecting approaches for different requirements. - Systematic evaluation practice using realistic labelled examples, including failure cases and permission boundaries. - Sound judgment about security, reliability, human approval, state persistence, and safe recovery. - Ability to coordinate multiple agent-led workstreams and assess code and architecture to production standards.

Nice to have

- Long-running customer-facing agents, substantial internal process automation, or agent-supported DevOps and CI/CD workflows. - Advanced retrieval approaches such as graph-based or agentic RAG.

Benefits and work setup

- Remote-first work across Europe, with flexible hours, defined core hours, and no internal meetings on Friday afternoons. - Salary band of £117,850 or local currency equivalent, plus stock options. - 25 days of annual leave plus public holidays, with the option to exchange public holidays, and a day off for your birthday. - Annual remote-work equipment allowance up to £1,200 or €1,200 and monthly wellbeing support up to £150 or €150.
