Sr. Software Engineer

We are seeking a Senior Software Engineer to join our team in Washington, DC. You’ll own various capabilities across our product lines and play a critical role in bringing novel technologies to market. In a given week you could switch between embedded C on a Xilinx Zynq SoC (bare-metal, FreeRTOS, or embedded Linux), Python tooling for test automation and data analysis, ground-support and test-station software that talks to hardware over Ethernet or serial, and the CI, build, and version-control infrastructure behind it. You will have enough hardware fluency to read a schematic, sit at the bench with a scope, and debug where software meets hardware. You will also write code others can maintain, set up the practices around it, and contribute to company strategy. We're a close-knit, mission-aligned team that likes building side by side in our DC office, and we're looking for someone with startup DNA who moves fast and wants real ownership of the hardware flying on the next generation of spacecraft. With an oversubscribed funding round just closed and several high-stakes projects underway with NASA and the U.S. Space Force, we're paving the way for the future of spaceflight, and this is your chance to help build it from the ground up.

Key Responsibilities

• Develop embedded C on a Xilinx Zynq SoC (bare-metal, FreeRTOS, or embedded Linux).
• Build Python tooling for test automation and data analysis.
• Develop ground-support and test-station software that communicates with hardware over Ethernet or serial.
• Own the CI, build, and version-control infrastructure (DevOps).
• Debug at the hardware–software boundary: read schematics and work at the bench with a scope.
• Establish and champion software practices — code review, testing, and documentation.
• Collaborate closely with GNC, electrical, and mechanical teams.
• Own specific software-based capabilities for Magma’s product suite and clearly communicate technical concepts across cross-functional teams.
• Occasional travel required to support program and customer needs.

Required Qualifications

• Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field.
• 6+ years of software engineering experience.
• Proficiency in embedded C and Python.
• Hardware fluency: able to read a schematic and debug at the bench with an oscilloscope.
• Experience writing maintainable code and setting up code review, testing, and documentation practices.
• Must be a U.S. Person (U.S. citizen, permanent resident, or asylee/refugee) due to ITAR/EAR export control requirements.

Preferred Qualifications

• Experience in spaceflight, defense, or other high-reliability environments.
• FPGA or SoC experience (VHDL/Verilog, Vivado, processor-to-logic interfaces) is a significant bonus but not required.

What We Offer

• The opportunity to work on cutting-edge technology in the rapidly growing space industry.
• A high-energy, in-person team in DC that loves building together: collaborative, ambitious, and mission-aligned.
• Meaningful equity and real ownership: competitive salary plus an equity stake in a fast-growing, well-backed company.
• Comprehensive benefits, including 401(k), health insurance with dental and vision, paid vacation, paid sick leave, paid holidays, paid parental leave, and a free on-site gym.
• Flexible work schedule.
• Relocation assistance.
• The chance to make a real, visible impact on the future of space exploration. Your work will go to space!

The selected applicant will be required to pass a pre-employment third-party background check and reference check.
