Software Engineer, Sensing Systems

CHAOS Industries El Segundo, CA

El Segundo, CA

5d ago

$154k - $211k/yr Full time Backend Developer Python Automation

Apply Now

Job Description

Software Engineer focused on building sensing-system software for long-range EO/IR and multi-sensor integration, from desk work through autonomous field testing.

Responsibilities

Develop software that remains sensor-agnostic, staying generic across multiple camera heads and configurations while meeting required performance targets and adapting to mission and customer needs.
Create the end-to-end path from desktop development to field execution using harnesses and graphs that carry capabilities from first commit through simulation and hardware-in-the-loop, into complete end-to-end test runs with minimal manual effort.
Build autonomous field testing that runs full test suites against real hardware at CHAOS test sites, then reports results from the test execution.
Advance simulation and replay workflows so more features can be implemented and validated before touching hardware.
Implement multi-sensor integration including interfaces, timing, and data flow so radar, cameras, and other sensors operate as a single system.
Deliver and maintain fielded software with deployment, monitoring, and live fixes for edge hardware at both test and customer locations.

Requirements

3+ years of professional software engineering with ownership of a production system end to end: design, shipping, and fixing when issues occur.
A degree in Computer Science, Engineering, Physics or related field, or equivalent experience.
Strong Python for building services and engineering tools that other engineers rely on, beyond scripts and notebooks.
Comfort with Linux, Docker, networking, and CI, including bringing up a multi-service system on unfamiliar hardware.
Practical leverage from AI coding tools (such as Cursor or Claude Code) with a reasoned approach to what to delegate versus what to keep under direct control.
Grounding in the physical world: experience reading schematics, understanding a test rack, and collaborating with optics or RF engineers (via degree, hardware/sensor/robotics work, or field time where systems operate outside the lab).
Willingness to perform field work: be onsite when code runs and debug and ship fixes before the next flight.
Measurement-driven workflow: build the experiment, then trust and use the data.

Technologies

Python, Linux, Docker
Cursor, Claude Code
MATLAB, Simulink
CI, GStreamer, DeepStream, NVIDIA Jetson
GPU, CUDA
C++, TypeScript
Gazebo, Isaac Sim, Unreal

Benefits

Medical, dental, and vision benefits 100% paid by the company
401k with 50% company match up to 6% of pay
FSA, HSA, life insurance, and more
Free daily lunch while working onsite
Fully-stocked kitchen
Unlimited PTO
Casual dress code
Relocation assistance
Pre-IPO stock option grants
Annual bonuses (coming soon)

Additional Notes

This role is not: algorithm research; physics modeling; applied machine learning training on sensor data; pure DevOps (infrastructure is part of the work, but writing engineering-critical software is the focus).
Nice to have: cameras, EO/IR sensors, gimbals, radar, video pipelines such as GStreamer or DeepStream; embedded Linux or edge computing (especially NVIDIA Jetson) and GPU/CUDA work; robotics, autonomous vehicles, drones, or aerospace; hardware-in-the-loop test rigs or test automation against real hardware; simulation or game-engine work (Gazebo, Isaac Sim, Unreal); building AI agent harnesses/workflow graphs; C++ or TypeScript; defense/aerospace experience or a current U.S. security clearance.

Location and Requirements

Onsite in El Segundo, CA
Regular travel to test sites and field deployments
U.S. Person status required due to access needs for U.S.-only data systems
