Evals Software Engineer (Infrastructure)

Apollo Research, a leading AI safety research organization, is seeking a Senior Software Engineer to lead their infrastructure initiatives. This role focuses on building and maintaining the secure infrastructure foundation that powers frontier AI evaluations. As the infrastructure Lead, you'll have significant autonomy in technical decision-making and will directly enable the company's research mission through robust, scalable systems.

The position involves designing and implementing infrastructure for running frontier LLM evaluations, choosing appropriate technologies, and building internal tools for job orchestration and results storage. You'll work closely with researchers to understand and prepare for future infrastructure needs, particularly for agent deployments. Security is a key focus, as you'll be responsible for AWS account administration and organization-wide security processes.

Apollo Research specializes in behavioral model evaluations and auditing real-world AI models, with a particular focus on deceptive alignment - where models appear aligned but may be capable of evading human oversight. You'll be joining a talented team of researchers and engineers, working from their London office shared with the London Initiative for Safe AI (LISA).

The role offers competitive compensation, comprehensive benefits including unlimited vacation and sick leave, daily meals, and professional development opportunities. The company supports international candidates with visa sponsorship and relocation assistance through AI Futures Grants. The interview process is practical and focused on relevant technical skills rather than theoretical exercises.

This is an excellent opportunity for an experienced infrastructure engineer who wants to contribute to important work in AI safety while leading and scaling critical technical infrastructure.
