Overview
We are building a satellite-enabled, off-grid communications platform designed for the world’s most demanding and safety-critical environments. Our technology enables reliable communication and situational awareness where traditional connectivity fails, supporting real-world missions where reliability, performance, and resilience are non-negotiable.
We are seeking an experienced Firmware Engineer at the Senior or Staff level to design, build, and lead embedded systems that power mission-critical devices operating in harsh, power-constrained environments. This role spans hands-on development through architectural leadership, with opportunities to influence technical direction, mentor engineers, and shape long-term platform strategy.
Why This Role Matters
Firmware is the core of the platform. Every feature, optimization, and architectural decision directly impacts reliability, performance, and safety in real-world operations. This role offers significant ownership across the embedded stack, from board bring-up to production deployment, with the ability to influence engineering standards and system architecture at scale.
Responsibilities
Design, develop, and ship embedded firmware in C, C++, and Rust targeting Zephyr RTOS
Own firmware from concept through production deployment on custom hardware
Architect and implement scalable embedded systems for power-constrained, safety-critical environments
Lead board bring-up, device driver development, and hardware validation
Collaborate closely with electrical engineers on hardware design and system integration
Design and evolve communication protocols spanning satellite, cellular (LTE/5G), Bluetooth, Wi-Fi, and mesh networking
Drive system-level decisions around performance optimization, power management, and memory usage
Establish and maintain firmware standards, tooling, and development processes
Lead cross-functional initiatives with hardware, mobile, backend, and product teams
Mentor engineers through code reviews, design reviews, and technical guidance
Debug complex embedded systems using oscilloscopes, logic analyzers, JTAG, and power profiling tools
Evaluate new technologies and contribute to long-term architectural strategy
Required Qualifications
Senior Level: 4+ years of firmware development on embedded systems
Staff Level: 10+ years of firmware development with demonstrated technical leadership
Strong experience with RTOS-based systems (Zephyr, FreeRTOS, or similar)
Proficiency with hardware interfaces (UART, SPI, I²C, USB)
Experience with wireless technologies (Bluetooth, Wi-Fi, ZigBee, mesh networking)
Familiarity with cellular technologies (LTE, 5G, NB-IoT) and/or satellite communications
Hands-on experience debugging embedded systems at the hardware and firmware level
Proven ability to ship reliable firmware in production environments
Strong collaboration skills across hardware and software teams
Passion for building systems where reliability, security, and safety are critical
Preferred / Bonus Experience
Firmware security (secure boot, cryptography, threat modeling)
Power optimization and real-time performance tuning
Firmware Over-The-Air (FOTA) update systems
RF systems or wireless performance optimization
Regulatory and compliance experience (FCC, CE, safety certifications)
Experience in aerospace, defense, or other safety-critical industries
Contributions to open-source embedded projects
What We Offer
Competitive salary and equity
Medical, dental, and vision benefits
Unlimited PTO
Flexible parental leave
Remote work equipment stipend
Focus time with designated no-meeting days
High ownership, technical autonomy, and direct impact on real-world missions
