Role: Junior Firmware Engineer

Function: Firmware / Embedded Systems Engineering

Location: Bengaluru, India

Type: Full-time

Industry: Aviation & Aerospace

About Company

A venture-backed, seed-stage startup founded in 2023. The company is modernizing the spacecraft component supply chain for low-earth-orbit (LEO) satellite applications.

It specializes in Attitude Determination and Control System (ADCS) components — reaction wheels, star trackers, and torque rods. Headquartered in the US with operations in Bengaluru, India, the company serves satellite manufacturers and LEO constellation developers worldwide.

The team brings deep experience from high-volume space missions and is driven by a commitment to quality, affordability, and speed. The company has raised $2.2M in funding and is building critical infrastructure for the commercial space ecosystem.

Position Overview

This role is built for a hands-on firmware engineer who has explored embedded systems through academic projects or space club work and is ready to apply that curiosity in a real-world spacecraft hardware environment. The engineer will work on firmware for ADCS components — reaction wheels, star trackers, and torque rods — contributing to the full development cycle from bring-up to validation. This is a ground-floor prospect to grow with a fast-moving deep-tech startup building critical infrastructure for the commercial space industry.

Role & Responsibilities

- Develop and maintain firmware for ADCS hardware components including reaction wheels, star trackers, and torque rods
- Assist in bring-up, integration, and testing of embedded firmware on spacecraft subsystems
- Write and debug low-level embedded code for microcontrollers used in space-grade hardware




- Support hardware-software integration testing and document firmware behavior against hardware specifications
- Collaborate with hardware engineers to validate sensor interfaces and communication protocols
- Contribute to firmware version control, code reviews, and documentation practices
- Participate in troubleshooting and root cause analysis during component testing and qualification

Must Have Criteria

- 0–1 year of experience in firmware or embedded systems development (academic projects count)
- Hands-on project experience with microcontrollers — demonstrated through coursework, personal, or club projects
- Working knowledge of C for embedded/firmware development
- Exposure to communication protocols such as I2C, SPI, UART, or CAN
- Active participation in a college space club, satellite team, or aerospace project (e.g., CanSat, CubeSat, rocketry, or ADCS subsystem work)

Nice to Have

- Project experience specifically on ADCS subsystems — attitude sensing, reaction wheels, or control algorithms
- Familiarity with RTOS concepts (FreeRTOS or similar) in an embedded context
- Exposure to hardware-in-the-loop (HIL) testing or spacecraft simulation environments
- Experience with version control tools such as Git in a team project setting
- Prior internship or project collaboration with a space startup, ISRO student program, or aerospace research lab

What We Offer

- Direct ownership of firmware modules on real spacecraft hardware from day one
- Mentorship from engineers with experience across multiple space missions
- Onsite role in Bengaluru embedded within a globally connected US-India team
- Ground-floor opportunity at a seed-stage startup shaping the commercial space supply chain
