Job summary

Rain Industries Inc. in Alameda, California is seeking a Senior Software Engineer to lead the design and deployment of a mission simulation and system integration framework for multi-aircraft autonomy.

You will own end-to-end simulation stack development, work across perception, planning and flight software teams, and enable rapid iteration through scalable testing environments and validation workflows. This on-site role invites you to ship safety-critical software and to mentor others while

Qualifications

Strong experience in modern C++ for performance critical and safety critical applications.
Experience with Python for simulation and test tooling.
Strong, practical experience with building, deploying, and debugging applications on Linux-based systems and environments (e.g. Docker Compose, CMake, Conan, gdb/Valgrind/memcheck).
Experience working with or building simulation environments.
Systems & Simulation Thinking: running multi-host apps, multi-agent and real-time systems.
Execution & Ownership: ability to own a domain end-to-end in a fast-moving environment.

Responsibilities

Design and build a world simulation and sensor simulation stack that generates realistic EO/IR and environmental outputs, and integrates aircraft, autonomy, and external systems into a cohesive simulation environment.
Lead the end-to-end development of the simulation stack while acting as a force multiplier across the autonomy team—contributing to perception and mission behaviors as needed to accelerate system progress.
Develop and maintain integration pipelines and infrastructure to continuously deploy software into simulation, run large-scale integrated tests, and evaluate system performance across mission scenarios.
Integrate multi-system components (perception, planning, controls, comms) into cohesive simulation and test frameworks.
Develop infrastructure to support multi-agent simulation (multiple aircraft, human-in-the-loop operators, and external systems).
Own critical parts of the simulation stack end-to-end—from architecture to deployment to validation.
Build tools to evaluate system performance, failure modes, and degraded conditions in safety-critical scenarios.
Collaborate closely with engineers on autonomy, perception, and flight software to ensure simulation reflects real-world system constraints and behaviors.
Enable real-time and faster-than-real-time simulation to support training, testing, and algorithm development.
Drive system-level thinking—ensuring that simulation meaningfully represents interactions across subsystems and impacts mission success.
