By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions.\nThe company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach.\nHeadquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry.\nPosition Overview\nAs a Senior Embedded Software Engineer at Inversion you will own the development, testing, and deployment of highly reliable, low-latency flight software that runs on Arc’s vehicle avionics hardware. You will design and implement safety-critical code for microcontrollers, power distribution units, flight computers, and communication systems. Operating with high autonomy, you will bridge the gap between hardware and software, debugging boundary-level issues, establishing embedded coding standards, and ensuring our flight processors execute flawlessly through extreme reentry environments. \nKey Responsibilities:\nDesign, develop, and maintain high-reliability, real-time embedded software in C/C++ for Arc flight computers, microcontrollers, and actuators. \nArchitect and implement low-level device drivers for communication protocols including SPI, I2C, UART, CAN, Ethernet, and RS-422. \nOwn embedded software modules end-to-end, from early requirements definition through testing, qualification, and vehicle-level flight operations. \nBring up new avionics hardware platforms, debugging complex hardware-software boundary issues using JTAG, logic analyzers, oscilloscopes, and packet sniffers. \nIntegrate and validate embedded code using software-in-the-loop (SIL) and hardware-in-the-loop (HIL) test environments. \nPerform rigorous code reviews, establish technical standards, and mentor junior embedded engineers on the team. \nCollaborate closely with the core Flight Software and Simulation teams to align vehicle autonomy, telemetry architectures, and GNC algorithm execution. \nRequired Qualifications:\nBachelor’s degree in Computer Engineering, Computer Science, Electrical Engineering, or equivalent technical experience. \nTypically 5+ years of professional experience developing low-level embedded C/C++ software for real-time systems. \nHands-on experience with bare-metal microcontrollers and Real-Time Operating Systems (RTOS) like FreeRTOS, RTEMS, or VxWorks. \nProven capability to read electrical schematics, understand datasheet registers, and debug physical hardware using laboratory instruments. \nExperience implementing standard hardware peripheral drivers and serial communication protocols. \nExcellent verbal and written communication skills. \nMust have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.\nDesired Qualifications: \nExperience developing software for safety-critical or high-reliability applications (e.g., aerospace, automotive, or medical devices). \nFamiliarity with modern software development practices, including Git, unit test frameworks, static analysis tools, and CI/CD pipelines. \nProficiency in Python for test automation, data analysis, and hardware scripting. \nExperience developing embedded software on Linux-based systems. \nExperience developing FPGA designs and digital logic using VHDL, Verilog, or SystemVerilog. \nExperience developing custom Board Support Packages (BSPs), bootloader configurations, device startup code, and hardware abstraction layers (HAL). \nExperience participating in electrical schematic reviews and collaborating closely with hardware engineers to guide board-level design. \nExperience leading PCB bring-up, design verification testing (DVT), hardware qualification, and transition to production. \nPrior experience in a fast-paced aerospace startup or small hardware integration team. \nOur office headquarters is located in Playa Vista, CA. This position requires in office presence.\nThe California annual base salary for this role is currently $139,000 - $201,000. Pay Grades are determined by role, level, location, and alignment with market data. Individual pay will be determined on a case-by-case basis and may vary based on the following considerations: interviews and an assessment of several factors that are unique to each candidate, job-related skills, relevant education and experience, certifications, abilities of the candidate and internal equity. \nITAR Compliance:\nTo conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State. Learn more about the ITAR here. \nEqual Employment Opportunity:\nInversion provides equal employment opportunities to all employees and applicants without regard to race, color, religion, age, sex, gender identity, sexual orientation, national origin, veteran status, or disability. \nInversion collects and processes personal data in accordance with applicable data protection laws.
