Job description

We\'re building AWS for space, providing space experiments and technology demonstrations across LEO, deep space, and lunar orbit.

Our offerings include unmanned labs, testbeds for both dedicated and rideshare missions, and re-entry capsules for payload retrieval.

We simplify access to space with affordable pricing, end-to-end solutions, no minimum mass limits, zero integration fees, and quick deployment (6 months or less).

We serve biopharma, semiconductors, materials science, defense, and more.

Job Description

We are looking for an Embedded Software Engineer to design and develop the flight computers and software stacks that power our satellite missions. You will work on real-time embedded systems for every spacecraft subsystem including power, communication, ADCS, thermal, and payload control. This role demands hands-on development across hardware bring-up, firmware, and mission-critical software that must perform reliably in space.

Key Responsibilities:

• Architect, implement, and validate embedded software for on-board computers and subsystem controllers.
• Develop low-level drivers for sensors, actuators, radios, and communication buses (I2C, SPI, UART, CAN).
• Implement real-time task scheduling, fault detection, and redundancy mechanisms for mission-critical reliability.
• Work closely with avionics hardware engineers for board bring-up, hardware-software integration, and debugging.
• Develop communication protocols for satellite telemetry, telecommands, and payload data handling.
• Contribute to software-in-the-loop (SITL) and hardware-in-the-loop (HIL) test setups for mission validation.

Required Skills & Qualifications:

• B.E./B.Tech or M.E./M.Tech in Electronics, Computer Science, Aerospace, or related field.
• 2–6 years of experience in embedded software/firmware development.
• Strong proficiency in C/C++ and real-time embedded systems programming.
• Experience with bare-metal programming and RTOS (e.g., FreeRTOS, Zephyr).
• Solid understanding of digital electronics, microcontrollers, and processor architectures (ARM Cortex-M/R, RISC-V).
• Familiarity with debugging tools like JTAG, SWD, logic analyzers, and oscilloscopes.
• Proficient in Git, CI/CD pipelines, and automated testing practices.
• Knowledge of fault tolerance, watchdogs, and redundant system design in embedded systems.

Nice to Have (Preferred):

• Experience with space-grade or high-reliability systems (radiation-hardened processors, fault-tolerant software).
• Knowledge of communication protocols for satellites
• Exposure to ADCS algorithms, sensor fusion, or real-time control systems.
• Experience in satellite flight software frameworks or cubesat missions.
• Familiarity with Python/Matlab for simulation and data analysis.
• Understanding of aerospace software standards.
