London, UK Hybrid Employment £65,000 - £145,000

AI Security Institute is hiring a Senior Engineering Lead, Chem-Bio

Responsibilities

  • Lead CB's engineering team — set technical direction, define engineering standards, and own the roadmap for shared infrastructure, tools, and components used across CB's research projects.
  • Line-manage a small number of engineers — provide regular support, feedback, and development guidance to direct reports (expect 1–3 reports as the team grows).
  • Design and build reliable systems — architect and deliver the core platform that enables researchers to run experiments and ship results quickly, including LLM-based agent systems, evaluation frameworks, and supporting infrastructure.
  • Work closely with researchers — translate varied research needs across general agents, science agents, chemical and biological models and other CB workstreams into well-engineered, maintainable systems.
  • Hire and grow the team — run hiring pipelines for future engineering roles, contribute to interview design and candidate assessment, and help shape what great engineering talent looks like at AISI.
  • Shape engineering culture— establish ways of working, code quality standards, and development practices for a growing engineering team embedded in a research-heavy environment.
  • Represent CB engineering across AISI — coordinate with Core Technology and other engineering teams to share tooling, align on infrastructure, and avoid duplication.

Requirements

  • Significant experience writing production-level Python code that is scalable, robust, and easy to maintain, with a track record of leading technical work in a team.
  • Strong infrastructure and platform skills — experience with cloud environments (AWS), container orchestration (Kubernetes), and job scheduling (Slurm or similar).
  • Demonstrated experience leading or managing engineers — whether through formal line management, tech-leading a team, or running hiring pipelines. You don't need to have done all three, but you should be comfortable with at least one and keen to grow into the others.
  • Familiarity with the AI/ML ecosystem: OpenAI-compatible APIs, PyTorch, and the tooling around LLM-based systems.
  • Ability to work across multiple teams, understanding varied research needs and delivering reliable engineering solutions.
  • A sense of mission, urgency, and responsibility for success: Demonstrated ability to solve challenging problems, implement solutions efficiently and acquire any missing knowledge necessary to get the job done.
  • Motivated to build software with direct policy impact.
  • Strong communication skills, with the ability to work effectively in a dynamic, multidisciplinary team environment.

Nice to Have

  • Experience working in a research environment — you don't need to be a researcher, but you should be comfortable working alongside them and translating ambiguous research requirements into engineering plans.
  • Familiarity with computational biology tools, workflows, or datasets.
  • Experience building or maintaining internal developer platforms, shared libraries, or CI/CD systems for technical teams.

Work Arrangement
