Senior Embedded Software Engineer; Onsite

Position Overview

Senior Embedded Platform Software Engineer – Melbourne, FL (US‑based, onsite). This role focuses on platform control software for custom avionics processing ASICs or advanced MPSoC devices.

• Develop embedded platform software supporting processor control, power‑management flows, and ASIC state coordination.
• Implement and integrate secure boot orchestration components, cryptographic validation routines, and platform trust enforcement.
• Design, implement, and bring up low‑level drivers, HAL layers, diagnostics, and platform initialization software.
• Work extensively in virtual development environments (simulation, emulation, virtual platforms, FPGA prototypes) before hardware availability.
• Collaborate with subcontract suppliers responsible for custom boot loader and early‑boot software development.
• Review, validate, and integrate supplier deliverables (bootloaders, BSP components, startup sequences) into the platform software stack.
• Collaborate with OS and BSP vendors to integrate and configure RTOS components.
• Debug and root‑cause hardware/software interaction issues.
• Work within pipelined build and test development environments (automated build systems, CI/CD pipelines, continuous testing frameworks).
• Identify opportunities to optimize development workflows, improve efficiency, and introduce innovative tools or methods.
• Document designs, contribute to coding standards, and support cross‑functional integration activities.
• Mentor junior engineers and contribute to a positive, collaborative team dynamic.

• Degree in Science, Technology, Engineering or Mathematics (STEM) or an advanced degree in a related field plus minimum 3–5 years of relevant experience.
• Experience developing embedded software for complex SoCs or custom ASIC architectures.
• Proficiency in C/C++ and embedded systems design.
• Experience working in virtual development environments such as simulation, emulation, or FPGA prototypes.
• Hands‑on experience with board bring‑up, hardware abstraction layers, diagnostics, and driver development.
• Understanding of secure boot flows, key validation mechanisms, and trusted platform initialization.
• Solid understanding of ASIC/SoC architectures, register maps, interrupts, reset logic, and hardware control interfaces.
• Experience with RTOS environments.
• Demonstrated ability to think creatively, propose novel solutions, and identify efficiencies.
• Highly self‑motivated, team‑driven, and committed to delivering high‑quality technical work.

• Experience with pipelined build and test development environments (CI/CD, automated build/test pipelines, or continuous integration frameworks).
• Experience developing or overseeing custom boot loader or early‑boot deliverables from third‑party vendors.
• Direct experience integrating BSP components.
• Experience with RTOS or embedded Linux configurations (Wind River VxWorks).
• Background in platform security, secure provisioning, or hardware trust anchors.
