Tools for Humanity is looking for a Senior Embedded Systems Engineer to own end to end embedded software development of new concept devices. This role will work closely with Software, Product, UX, and Industrial Design teams to develop functional concepts driving the technological roadmap at Tools for Humanity.

Key Responsibilities:

• Own the architecture, development, maintenance, and debugging of embedded firmware for concept devices to rapidly de-risk future programs
• Support hardware validation, test coverage improvements, and early design decisions for the hardware team.
• Design and implement low-level drivers and board support packages (BSPs) for microcontrollers, sensors and SoCs.
• Drive hardware/firmware integration and debug issues across electrical and software boundaries.
• Participate in design reviews and provide input on embedded system architectures and testability.
• Work collaboratively with cross-functional teams on concept integration into product roadmap with a focus on stability, power, and performance.
• Evaluate, debug, and validate new hardware designs, leveraging oscilloscopes, logic analyzers, and other lab tools.
• Collaborate with cross-functional teams (mechanical, software, product) to optimize system performance.
• Author and maintain documentation for firmware architecture, testing procedures, and validation results.
• Coordinate with software engineers to validate system-level behavior and address hardware/software integration issues.
• Support production system debug as needed.
• Mentor junior engineers in development best practices.

About You:

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related field.
• 7+ years of hands‑on experience in firmware development for embedded systems, with a strong understanding of electronics and hardware‑software interactions.
• Experience developing consumer electronics systems at large scale.
• Proficiency in C/C++ for embedded systems, with experience developing for bare‑metal, RTOS, or Linux‑based systems.
• Experience with Zephyr RTOS, Linux kernel internals, and real‑time system design.
• Familiarity with standard industry tools: oscilloscopes, logic analyzers, JTAG, UART, SPI, I2C, PCIe, etc.
• Strong debugging skills in both hardware and software domains, including use of low‑level debuggers and trace tools.
• Hands‑on experience with microcontrollers, SoCs, and custom board bring‑up.
• Experience developing manufacturing test software, including boundary scan, functional test, and system diagnostics.
• Ability to work independently on complex projects and take full ownership of deliverables.
• Ability to debug complex cross‑domain issues (hardware/software) in a fast‑paced, iterative development environment.
• Committed to rigorous documentation and testing practices.
• Comfortable working in a start‑up or high‑velocity team environment, with a proactive, hands‑on approach.

Nice‑to‑Haves:

• Exposure to secure boot, firmware update pipelines, and embedded cybersecurity.
