THIS POSITION IS FOR STRATEGIC TECHNOLOGY CONSULTING

(STC), AN

ARCFIELD COMPANY

Strategic Technology Consulting (STC), an Arcfield Company, is seeking a Senior Embedded Software Engineer with expertise in Navigation Fusion and PNT software architecture. This role will focus on the design, development, and deployment of deterministic embedded software for PNT systems. The ideal candidate will bring strong experience in embedded C/C++, bare-metal or RTOS-level development, Kalman filtering, sensor fusion, timing architectures, hardware/software integration, and resource-constrained tactical systems. This role requires a highly autonomous engineer who can take ownership of critical navigation software from low-level implementation through integrated system performance, helping ensure resilient PNT and timing are maintained at the tactical edge.

Responsibilities:

Build the

Fusion Engine:

Architect and write the C++ embedded pipelines for multi-sensor state estimation, implementing Extended/Unscented Kalman Filters (EKF/UKF) or factor graphs to tightly couple GPS, inertial, and alternative navigation sources. Develop the

Architecture:

Design the deterministic software architecture that manages rigid timing deadlines, ensuring sensor ingestion and fusion math execute on SWaP-constrained processors

Implement Autonomous PACE Logic:

Code the intelligent fallback mechanisms during jamming or spoofing events.

Maintain Time & Crypto Sync:

Write the low-level control loops that monitor local oscillators (CSAC/OCXO) during prolonged GPS holdover.

Enforce Software MOSA:

Build rigid Hardware Abstraction Layers (HAL) so new hardware and sensors can be easily integrated. Deploy to the

Edge:

Optimize mathematical models (matrix inversions, covariance updates) to run cleanly on tactical ARM Cortex or embedded Linux architectures. Qualifications

BS 8-10, MS

6-8, PhD 3-5 (Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field). Experience writing production-grade C and modern C++ for embedded systems. Deep expertise in Navigation Fusion, state estimation, and sensor integration (e.g., implementing Kalman filters, tightly coupled GPS/INS, or dead-reckoning algorithms). Demonstrated experience designing or extending a "PNT OS" or complex, timing-critical deterministic middleware for multi-sensor platforms. Intimate knowledge of precision timing concepts, hardware clock steering (DACs, oscillators), and synchronization protocols (PPS, 10MHz, PTP/IEEE 1588). Demonstrated ability to work autonomously in an architecture-driven environment, taking complex mathematical subsystems from initial concept through to deployed capability. Understanding of VITA standards (VITA49 for VITA Radio Transport, VITA90) and SOSA hardware/software profiles. Must be able to obtain and maintain a U.S. DoD Secret Security Clearance. Equal Pay Act This is the projected compensation range for this position. There are differentiating factors that can impact a final salary/hourly rate, including, but not limited to, Contract Wage Determination, relevant work experience, skills and competencies that align to the specified role, geographic location (For Remote Opportunities), education and certifications as well as Federal Government Contract Labor categories. In addition, Arcfield invests in its employees beyond just compensation. Arcfield 's benefits offerings include, dependent upon position, Health Insurance, Life Insurance, Paid Time Off, Holiday Pay, Short Term and Long-Term Disability, Retirement and Savings, Learning and Development opportunities, wellness programs as well as other optional benefit elections.
