Job summary

Urban Sky in Denver, CO seeks a Senior Firmware Engineer to own the HUSKY flight software end-to-end, from hardware interfaces to build and deployment processes. You will shape the architecture, drive reliability, and work with defense customers to integrate with flight platforms.

This high-ownership role emphasizes secure, robust embedded Linux software on Linux-based devices, Go-based control planes, and collaboration with a multidisciplinary team to ensure mission success.

Qualifications

• 5+ years of embedded software engineering on Linux-based embedded devices.
• Strong Go programming and systems programming fundamentals.
• Experience with Linux SOM/SBC platforms, board bring-up, device trees, kernel/driver config, and peripheral integration.
• Experience with Yocto/Buildroot and shipping/updating containerized software on devices in the field.
• Experience with Zephyr RTOS firmware on microcontrollers and Linux-MCU interfaces.

Responsibilities

• Own the HUSKY flight software end-to-end – architecture, development, quality, and release – as the technical lead for the platform.
• Keep the vehicle hardware working through software: sensors, batteries, power distribution and outputs, GNSS, radios, and payload connections.
• Ensure reliable communications over RF, satellite, and IP links with robust data handling.
• Design for flight safety with fault detection, watchdogs, graceful degradation, and safe-default behaviors.
• Own build, security, and delivery processes for the fleet: CI/CD, release/config management, and defense variants.
• Build and maintain the test infrastructure for the platform.
• Define interfaces between HUSKY and subsystems, payloads, and mission control systems.
• Implement security controls and support DoD accreditation (encrypted comms, hardened configs, secure boot, access control).
• Serve as a technical point of contact for defense customers integrating with HUSKY.
