CesiumAstro develops advanced communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We are seeking a Staff Software Engineer – Test Automation & Infrastructure to design and scale automated test systems that validate complex RF and satellite communications payloads.
This role sits at the intersection of software development and hardware test engineering. You will build robust automation frameworks and infrastructure that ensure reliable, repeatable system validation, directly improving product quality and accelerating development cycles.
Key responsibilities include:
- Develop automated test software to control laboratory instrumentation (signal generators, spectrum analyzers, power supplies, network equipment)
- Implement and maintain test sequences for system-level and component-level validation
- Support integration and execution of tests across hardware and software environments
- Debug and troubleshoot test failures across software, hardware, and interface layers
- Design and implement software for device under test (DUT) control, including command handling, telemetry ingestion, and state management
- Build reusable automation frameworks and scripts to streamline test development
- Apply best practices in software engineering: modular design, version control, code reviews
- Design and maintain scalable test automation infrastructure supporting multiple configurations and environments
- Integrate automated testing into CI/CD pipelines
- Act as a technical bridge between software and test engineering teams
- Collaborate with systems, hardware, and software teams to ensure system testability
- Identify and implement improvements to test automation architecture
- Drive simplification and standardization to reduce development cycle time
- Continuously improve test processes, tools, and methodologies
You will work in a dynamic, cross-functional environment with hands-on, interactive, and autonomous work. This is a full-time role offering company stock options and a comprehensive benefits package including health, dental, vision, HSA, FSA, life, disability, and retirement plans.
