Engineer: Senior Embedded Systems Engineer at Nanobiosym in Cambridge, MA, USA

Job description

• 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.

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.

Requirements

• 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.
• 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.
