About the role

Relling is looking for a killer engineer to lead tools and projects.

You will:

  • Build and optimize large-scale data pipelines handling multimodal sensor streams
  • Design APIs and SDKs for dataset access, visualization, and annotation
  • Develop tooling for synchronization, compression, and quality verification of sensor data
  • Deploy scalable infrastructure across AWS (S3, Aurora, ECS, Lambda, etc.)
  • Work closely with clients (AI labs, robotics teams) to tailor dataset schemas and delivery systems
  • Shape product direction, engineering culture, and hiring processes from the ground up

You might be a fit if you:

  • Thrive in ambiguous, high-agency environments and enjoy owning problems end-to-end
  • Have deep experience in Python, C++, or Rust, and care about reliability and performance
  • Are fluent in distributed systems, computer vision, or embedded data collection pipelines
  • Have prior startup experience or a strong desire to work close to the metal

We’re looking for SUPER high agency people who want to take ownership and build and lead projects.
