Job summary

Atoms seeks a Senior Software Engineer to architect log replay and scenario execution within our core simulation platform. You will move recorded logs from storage to replayable test cases, score results, and own execution, determinism, and reporting across on-road and off-highway programs.

You’ll build the execution layer, manage clock control and seeds, and ensure reproducible runs with software version traceability. This role includes CI integration and scalable tooling for engineers.

Qualifications

• Bachelor's degree in Computer Science, Robotics, Electrical Engineering, or a related field; 5+ years of software engineering, or a Master's with 3+ years.
• Proficiency in C++ and Python and ability to read, navigate, and debug large codebases.
• Experience building and operating data or test infrastructure at scale, including pipelines, batch execution, storage and indexing.

Responsibilities

• Build and maintain log replay pipeline converting recorded logs into replayable test cases with ingestion, indexing, retrieval, and on-demand replay.
• Develop scenario execution layer ensuring deterministic runs with clock control, seeds, and configuration management.
• Integrate simulation into CI pipelines and maintain nightly/regression workflows with traceable failures.
• Define metrics and reporting to reduce failing runs to actionable items.
• Scale simulations for large batches and manage cost as volume grows.
• Create interfaces, visualizations, and CLI tools for engineers unfamiliar with the platform.
• Collaborate cross-functionally with autonomy/robotics teams from simulation to bench to vehicle.
