Software Engineer Lead – Embedded Systems and RTOS - JAX

Tactical Air Support, Inc.

Software Engineer Lead - Embedded Systems and RTOS
Jacksonville, FL

Salary Range: $110.00 -$120.00 /hr. DOE

Summary

We seek an experienced Software Engineering Leader with deep expertise in real-time embedded systems and Real-Time Operating Systems (RTOS) to lead an inaugural RTOS initiative. This part-time role will drive the development and integration of RTOS-based software for mission-critical systems and high-fidelity simulation environments, primarily supporting Department of War (DoW) training and operational needs.

The ideal candidate brings proven leadership in building and managing software teams for complex real-time simulation devices, combined with hands-on technical depth in real-time software architecture, porting, optimization, and government-compliant documentation. This position offers the opportunity to shape our RTOS strategy from the ground up, mentor a high-performing team, and deliver reliable, deterministic software solutions that meet stringent DoW requirements. Part-time (flexible hours, with potential for hybrid/remote elements).

Responsibilities

• Architect, design, and implement RTOS-based embedded software solutions to support mission system development and real-time simulation. Establish best practices for task scheduling, interrupt handling, and determinism.
• Provide expert guidance on real-time software design, developing device drivers, middleware, and low-level interfaces. Contribute directly to coding, debugging, and integration efforts using C/C++, with Linux-based real-time extensions or other RTOS platforms.
• Prepare cost estimates, Basis of Estimate (BOE) documents, technical proposals, and inputs to budgets.
• Integrate embedded RTOS components with host systems, hardware interfaces, and simulation frameworks to achieve deterministic performance.

Requirements

• Bachelor's degree in Computer Science, Software Engineering, or related field (advanced degree or certs CompTIA Security+ a plus).
• Experience: 15+ years in software engineering for DoW simulation, training devices, or mission systems, with significant hands-on work in real-time embedded software and RTOS environments.
• Deep knowledge of real-time systems, including task management, determinism, interrupt handling, hardware-software integration, and performance optimization.
• Proficiency in C/C++ (and related languages or assembly); experience with Linux system/network administration.
• Experience with simulation frameworks, OpenGL-based displays/APIs, instructor operator stations (IOS), and integration of avionics/weapons systems (e.g., glass cockpits, radar, missiles).
• Proven success growing and managing software teams (up to 30+ engineers), including direct reports and matrix environments. Track record of mentoring, low turnover, process improvement, and delivering complex projects on time and within budget.
• Familiarity with MIL-STD-498 and other CDRLs, configuration management (e.g., Bugzilla), and working in secure environments.
• Active or ability to obtain SECRET security clearance required.
• Valid driver's license.
• Must be lawfully eligible to work in the United States, complete a U.S. government I-9 form, and successfully pass a government background check.

Desired Skills/Experience

• Direct experience leading or implementing RTOS in defense/aerospace simulation or mission systems (e.g., VxWorks, INTEGRITY, or similar deterministic platforms).
• Background in virtual training environments, flight/weapon system trainers, or related DoD programs.
• Experience with modern tools for real-time analysis, modeling, and automated documentation.

Work Authorization and Environment

• Must be lawfully eligible to work in the United States and complete a U.S. government I-9 Form.
• Tactical Air Support is a DrugAlcohol-Free Workplace. Pre-employment, random, or for cause drug/alcohol testing (including for marijuana) required.
