Job description

Job Title: Sr. Embedded Firmware Engineer (Rust and C)

Position Overview: We are seeking an experienced Sr. embedded firmware engineer with a strong background in Rust to help re‑design and port existing firmware into Rust. This role focuses on designing for manufacture and scale secure, high-performance firmware for ARM Cortex‑M and other microcontrollers while implementing hardware abstraction layers and ensuring robust board bring‑up for novel platforms.

Key Responsibilities:

Firmware Architecture & Security:

• Assist in designing and implementing a secure firmware architecture with robust secure update mechanisms.
• Develop and integrate secure firmware modules leveraging best practices and industry standards.

Hardware Abstraction and Peripheral Integration:

• Implement HALs and drivers for unsupported peripherals and features.
• Port or integrate low‑level drivers for Bluetooth, cellular, and other communication modules.

System Bring‑Up & Application Code:

• Contribute to board bring‑up tasks using Rust.
• Develop firmware application code and new Rust crates for unsupported SoCs as needed.

Rapid Prototyping & UI Framework Selection and bring products to market:

• Evaluate and select an embedded GUI framework that supports rapid prototyping for UI needs. As well as late stage development to DFM and transition product to scale and final product launch

Collaboration & Documentation:

• Work closely and communicate clearly with team to document designs, review code, and ensure compliance with security and performance guidelines.

Qualifications:

Essential:

• Proven expertise with high‑performance ARM Cortex‑M and other microcontrollers.
• Extensive experience with bare‑metal programming and embedded systems.
• Demonstrated experience designing and developing secure firmware.
• Proficiency in Rust, particularly in board bring‑up and low‑level hardware interaction.

Preferred:

• Familiarity with the Rust embassy framework.
• Hands‑on experience with Arm TrustZone.
• Experience in writing Rust crates for unsupported SoCs.
• Solid understanding of secure firmware update protocols and architecture.
• Experience with medical device compliance and documentation as per FDA and ISO13485 standards

PhD or MS / ME in EECS

What We Offer:

• An innovative work environment tackling challenging embedded systems projects.
• Opportunities for professional growth in secure firmware development and advanced embedded technologies.
• Competitive salary and benefits package.
