Principal Embedded Software Engineer - Platform and Foundation Software; Onsite

Principal Embedded Platform Software Engineer

At RTX, the world’s largest aerospace and defense company, the Advanced Processing Architectures Software organization delivers embedded processing solutions used across a wide range of safety‑critical commercial and military avionics applications. We are seeking a Principal Embedded Platform Software Engineer to lead the development of platform control software for next‑generation processing architectures—including advanced SoCs, MPSoCs, and custom silicon.

• Lead the design and development of embedded platform software for processor control, power management, system health monitoring, and hardware coordination.
• Architect and integrate secure boot flows, platform security mechanisms, and trusted initialization paths.
• Develop and guide implementation of low‑level drivers, HAL layers, diagnostics, and bring‑up tools for new processing hardware.
• Drive early embedded software development using virtual platforms (simulation, emulation, FPGA prototypes) prior to hardware availability.
• Provide technical leadership and oversight to subcontract suppliers developing bootloaders, BSPs, and secure startup software.
• Lead integration and validation of RTOS/BSP deliverables, including Wind River Helix components.
• Collaborate with hardware, systems, and SoC/MPSoC design teams to define hardware‑software interfaces and drive architectural decisions.
• Lead debugging and resolution of complex hardware/software interaction issues across pre‑silicon and post‑silicon phases.
• Support certification activities by contributing to design documentation, requirements traceability, verification strategies, and safety‑critical artifacts.
• Drive improvements in software processes, automation, pipelined build/test workflows, and development efficiency.
• Mentor junior and mid‑level engineers, foster collaboration, and coordinate small team efforts.
• Identify risks, propose innovative solutions, and influence long‑term platform strategy.

• Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, Computer Science, or related field.
• Typically 8+ years of embedded software development experience.
• Strong proficiency in C/C++ and embedded systems architecture.
• Experience with SoC/MPSoC platform software (experience with ASIC‑based platforms strongly preferred).
• Demonstrated experience leading small teams or technical work streams.
• Experience with virtual development environments (simulation, emulation, QEMU, FPGA prototypes).
• Hands‑on experience with driver development, hardware bring‑up, and system initialization flows.
• Background in avionics‑related capabilities such as system health monitoring, BIT, redundancy management, or deterministic scheduling.
• Strong knowledge of secure boot concepts, platform security, and trusted execution fundamentals.
• Experience working with pipelined build and test environments (CI/CD, automated build/test pipelines).
• Solid understanding of register‑level hardware interfaces, interrupts, and reset flows.
• Strong communication skills and ability to influence cross‑functional teams.

• Experience with Wind River Helix RTOS or similar safety‑critical real‑time operating systems.
• Experience contributing to or leading avionics certification or safety‑critical development processes.
• Experience guiding early‑boot or secure startup software development.
• Experience driving process improvements, workflow automation, or architectural modernization initiatives.
• Experience coordinating with external suppliers or integrating third‑party bootloaders, BSPs, or RTOS deliverables.

• Medical, dental, and vision insurance.
• Three weeks of vacation for newly hired employees.
• Generous 401(k) plan with employer matching and separate employer retirement contribution.
• Tuition reimbursement program.
• Student Loan Repayment Program.
• Life insurance and disability coverage.
• Optional coverages including pet insurance, home and auto insurance, additional life and accident insurance, critical illness insurance, group legal,  protection.
• Birth, adoption, parental leave benefits.
• Ovia Health, fertility, and family planning.
• Adoption Assistance.
