Position Overview: We are looking for a seasoned Senior Embedded Firmware Engineer with deep Rust expertise to lead the re-architecture and migration of existing firmware into Rust. You will be central to building secure, high-performance firmware targeting ARM Cortex-M and other microcontrollers - covering everything from hardware abstraction layers and board bring-up to DFM-ready product launches at scale. Key Responsibilities • Collaborate on the design and implementation of a secure firmware architecture, including robust and reliable firmware update mechanisms. • Build and integrate secure firmware modules in alignment with industry best practices and established security standards. • Develop HALs and peripheral drivers for hardware not yet covered by existing crates or frameworks. • Port and integrate low-level communication drivers for Bluetooth, cellular, and other connectivity modules. • Write firmware application code and author new Rust crates for SoCs that lack existing ecosystem support. • Execute board bring-up workflows using Rust tooling and debugging infrastructure. • Research, evaluate, and select an embedded GUI framework suited to rapid UI prototyping as well as the demands of late-stage DFM and high-volume product launch. • Communicate clearly and consistently with the broader team - contributing to design documentation, participating in code reviews, and upholding security and performance standards across the codebase. Required Qualifications • Proven track record working with high-performance ARM Cortex-M microcontrollers and comparable architectures. • Substantial experience with bare-metal embedded programming across resource-constrained systems. • Hands-on background designing and building secure firmware for production hardware. • Strong command of Rust in embedded contexts, including board bring-up and direct hardware register interaction. Preferred Qualifications • PhD or MS/ME in EECS or a closely related field. • Working knowledge of the Rust Embassy async embedded framework. • Practical experience with Arm TrustZone security architecture. • Prior work authoring Rust crates targeting unsupported or novel SoCs. • Familiarity with FDA and ISO 13485 compliance requirements for medical device firmware. • Solid grasp of secure firmware update protocols, threat models, and verification strategies.
