Embedded C is a programming language used to develop software for embedded systems, including microcontrollers. A Microcontroller Firmware Developer writes the actual firmware that runs on microcontrollers, often using Embedded C. While Embedded C refers to the language, the Firmware Developer role involves applying that language to create functional firmware. Both roles require similar skills and certifications, and they are often used interchangeably in industry contexts.

JOB DESCRIPTION
Embedded Firmware Engineer – GNSS / Inertial Navigation Systems
Defense / PNT R&D | Client-Confidential Engagement | U.S. Persons Only
Client Sector
Defense contractor — Position, Navigation & Timing (PNT) technology
Engagement Type
Contract / Contract-to-Hire (via GDI Infotech)
Work Eligibility
U.S. Citizen required — NOFORN program restrictions apply
Location
Onsite/hybrid with client; specifics confirmed at engagement
Period of Performance
Initial deliverables due within 180 calendar days of requirements release, plus up to 90 days of post-delivery support
ABOUT THE OPPORTUNITY
GDI Infotech is supporting a defense technology client that develops mission-specific navigation and timing solutions for government customers. The client's PNT (Position, Navigation and Timing) Directorate is seeking embedded firmware engineers to support two related Research & Development efforts: a multi-receiver GPS/inertial navigation card (“M-REGI”) and a secure, non-“Over-The-Air” timing and ephemeris delivery system (“Secure Start”).
Candidates with strong embedded C/C++ and Linux/RTOS experience, ideally with GNSS or inertial navigation exposure, are strongly encouraged to apply.
WHAT YOU'LL WORK ON
• M-REGI (Navigation Card): Developing embedded C/C++ firmware for a custom circuit card built around a Microchip SAM9X60 ARM processor, integrating dual GPS satellite receivers and a tactical-grade Inertial Measurement Unit (IMU).
• Implementing Multi-Hypothesis Tracking (MHT) logic to arbitrate between two satellite-based navigation solutions using covariance, satellite tracking, and spoofing-detection metadata.
• Secure Start (Timing/Ephemeris POC): Building a proof-of-concept, laptop-based system (Linux/Ubuntu) that generates and delivers precise satellite timing and ephemeris data to a navigation receiver without relying on standard over-the-air signals — reducing vulnerability to spoofing.
• Working from orbital-parameter curve-fit algorithms (SDP4-based), Look-Up Table generation for GPS/Galileo constellations, and Precision Time Protocol (PTP) synchronization.
• Customizing Linux RTOS components (U-Boot, buildroot, kernel) for real-time embedded operation using the Yocto project.
• Building a lightweight CI/CD pipeline appropriate for an R&D environment.
• Documenting code structure, data flow, and user interface/configuration parameters.
• Providing up to 90 days of post-delivery engineering support, including troubleshooting, minor code changes, and knowledge transfer/training.
REQUIRED QUALIFICATIONS
• Strong hands-on experience developing embedded firmware in C/C++.
• Experience with embedded Linux, including kernel/buildroot customization and real-time operating system concepts (Yocto project experience a plus).
• Familiarity with serial, USB, and TCP/IP communication interfaces on embedded platforms.
• Ability to work from block diagrams, written specifications, and MATLAB reference scripts to implement equivalent functionality in firmware.
• Comfort working in a small, fast-moving R&D environment with evolving requirements.
• U.S. Citizenship required; ability to comply with NOFORN handling requirements (no dissemination to foreign nationals, entities, or governments).
PREFERRED / NICE-TO-HAVE
• Background in GNSS/GPS receiver systems, inertial navigation, or Extended Kalman Filter (EKF) implementations.
• Experience with satellite orbital mechanics or TLE (Two-Line Element) data / SGP4-SDP4 propagation models.
• Familiarity with Precision Time Protocol (PTP) or other precision timing/synchronization systems.
• Experience building CI/CD pipelines for embedded or R&D software workflows.
• Working knowledge of IEEE 730 (Software Quality Assurance Plans) or similar SQA frameworks.
• Prior experience on defense, aerospace, or other ITAR/NOFORN-controlled programs.
