Quest Defense Systems & Solutions is seeking a highly skilled Embedded Software Engineer specializing in deterministic real-time execution and multicore architecture. In this role, you will develop and maintain low-level embedded software while collaborating with systems, hardware, and verification teams to ensure reliable performance in mission-critical environments.
Responsibilities
- Develop and maintain low‑level embedded software using C, C++, and assembly, with a focus on processor‑level control and deterministic execution
- Design, implement, and analyze multicore synchronization strategies including cache management, interference mitigation, and timing‑aware resource coordination
- Perform complex analytical evaluations such as Worst‑Case Execution Time (WCET) assessments and DCCC (Deterministic Cache and Core Contention) analyses
- Familiarity with DO‑178C objectives, particularly within rigorous Level A verification environments and automated test frameworks
- Integrate and validate interfaces with FPGA/ASIC components, ensuring reliable, timing‑critical embedded communication
- Apply proven experience in avionics, safety‑critical, or deterministic real‑time systems to guide architectural decisions and verification strategies
- Use ARM DS IDE, DSTREAM, and Python‑based automation tools for debugging, instrumentation, trace analysis, and workflow optimization
- Participate in architecture discussions, design reviews, verification planning, and continuous improvement of real‑time multicore development processes
Skills
- U.S. citizenship is required
- Bachelor's degree in software engineering or a related engineering discipline with 4+ years of relevant Software Engineering experience in avionics or electronic controls embedded development in a safety or mission critical environment (ie: aerospace, military)
- Demonstrated expertise in low‑level embedded software development in C, C++, and assembly
- Hands‑on experience with multicore synchronization, S32 Processor family, cache behavior, interference channels, and deterministic execution strategies
- Ability to perform sophisticated analysis, including WCET and DCCC evaluations
- Familiarity with DO‑178C certification practices, especially Level A verification environments and associated test infrastructures
- Proven experience in avionics, safety‑critical, or other deterministic real‑time domains
- Experience with FPGA/ASIC interfaces and timing‑critical embedded communication protocols
- Proficiency with ARM DS IDE, DSTREAM, and Python for tooling, automation, and analysis
- Familiarity with the S32 processor family or similar ARM-based multicore platforms
- Prior experience with multicore processor architectures in avionics, aerospace, defense, or other safety-critical embedded systems
- Hands-on experience with deterministic execution analysis, timing closure, interference analysis, or resource contention mitigation
- Experience developing or supporting automated test frameworks, Python-based tooling, trace analysis, or debug instrumentation
- Experience working closely with FPGA, ASIC, hardware, systems, or verification teams in an integrated engineering environment
- Familiarity with low-level processor features such as cache configuration, memory management, interrupts, boot code, device drivers, or board support packages
- Experience participating in software architecture reviews, certification reviews, or technical customer discussions
- Experience in adoption and/or integration of emerging technologies (e.g., generative AI, automation platforms, digital assistants) into day-to-day operations for continuous improvement
- Active security clearance or the ability to obtain a clearance
