 * Embedded software development experience for complex SoC, including hands-on development and integration

 * Strong proficiency in C/C++ and embedded systems design

 * Experience developing low-level platform software such as board bring-up, hardware abstraction layers (HAL), diagnostics, and device drivers

 * Experience developing or integrating software within RTOS environments

Qualifications We Prefer

 * Experience with secure boot, cryptographic validation, or trusted platform initialization

 * Experience integrating board support package (BSP) components

 * Experience working within CI/CD pipelines or automated build/test environments

 * Strong hardware/software debug and root-cause analysis skills

 * Experience with high-rigor development processes such as DO-178B/C

 * Familiarity with SoC fundamentals such as registers, interrupts, reset logic, and hardware interfaces

As part of our commitment to maintaining a secure hiring process, candidates may be asked to attend select steps of the interview process in-person at one of our office locations, regardless of whether the role is designated as on-site, hybrid or remote.

## Description

We are seeking a Senior Embedded Platform Software Engineer to join our foundation software team. In this role, you will contribute to the development of platform control software that enables secure, deterministic, and robust operation of advanced SoC devices. You will contribute across core avionics functions such as early-boot software, platform security, hardware bring-up, system health monitoring, and fault detection.

This position provides a clear path for growth, whether you are looking to deepen your expertise in embedded foundation software or gradually step into broader technical leadership. You will have opportunities to shape platform architecture, lead key development initiatives, and take on higher-impact responsibilities as you master core avionics technologies.

What You Will Do

 * 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 such as simulation, emulation, virtual platforms, and FPGA prototypes before hardware availability

 * Work with and oversee subcontract suppliers responsible for custom bootloader and early-boot software development

 * Review, validate, and integrate supplier deliverables into the platform software stack

 * Collaborate with operating system and board support package vendors to integrate and configure RTOS components

 * Debug and root-cause hardware/software interaction issues

 * Work within pipelined build and test environments including automated build systems, CI/CD pipelines, and continuous testing frameworks

 * Identify opportunities to optimize development workflows, improve efficiency, and introduce new 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
