The role

Raydar is recruiting for this role on behalf of our client. Act as technical lead for the cloud, data and automation infrastructure behind a high-volume operation. Own backend services, data pipelines and distributed workflow systems, and build internal tooling that lets automated agents support day-to-day operations. Mentor engineers and lead cross-functional projects from idea through production.

What you'll do

  • Own core backend services that coordinate physical devices and on-prem servers, along with the data ingestion pipeline.
  • Build cloud infrastructure and data pipelines to store, process and deliver very large volumes of data.
  • Design infrastructure for running millions of compute tasks, including queues, workflow orchestration and scheduling.
  • Build AI infrastructure and internal tooling that supports agent-based systems for monitoring, logistics coordination and adaptive data analysis.
  • Lead ambiguous, cross-functional projects from concept to production.
  • Mentor teammates and help others build new skills.

What we're looking for

  • Strong experience with cloud orchestration services on AWS and Python backend development with a framework such as FastAPI or Django.
  • Impactful experience at a startup as it scaled.
  • Experience designing, building and shipping reliable distributed systems, including queues, orchestration and state machines.
  • Linux server administration and experience with distributed task queues.
  • Experience leading projects and mentoring engineers on small teams.
  • Up to date with the latest AI tooling.
  • A university degree in a quantitative or technical discipline, or comparable practical background.
  • High agency, strong ownership and clear communication in a fast-paced, tight-knit team.

Bonus points

  • Experience building LLM or agent systems, including tooling, evaluation, permissions and workflow design.
  • Ambition to step up from a Senior or Staff engineer role into a lead role.
  • Genuine curiosity about science domains.
  • Former founder or founding engineer.
