Drut Technologies is a datacenter infrastructure startup building high-performance disaggregated GPU systems powered by PCIe over a photonic fabric for dynamic composability. Our platform integrates Co-Packaged Optical technology into the Drut Fabric Interface Card, uses Broadcom PEX-89000 and OpenBMC to enable low-latency interconnects and programmable telemetry over a photonic fabric.

We are seeking an expert Senior Embedded C Developer with over 10 years of hands-on experience in low-level embedded development, specifically for RTOS-driven platforms. This role demands deep technical proficiency in firmware design, a proven capability to own entire codebases for embedded boards, and a history of delivering robust and scalable solutions for complex microcontroller-based systems, particularly those based on PIC architectures.

• Architect, design, implement, and maintain embedded firmware in C for real-time operating systems.
• Own and manage the complete firmware codebase for multiple board products, from concept to release.
• Develop, test, and debug low-level drivers for microcontroller peripherals (I2C, UART, SMBus, etc.).
• Lead system-level integration and comprehensive hardware validation; troubleshoot and resolve cross-functional issues involving hardware and firmware.
• Translate high-level requirements into manageable subtasks, delegate as needed, and ensure successful task delivery.
• Foster the creation of maintainable, legible, and testable code, adhering to industry best practices and documentation standards.
• Document interface specifications, functional requirements, and development iterations throughout the project lifecycle.
• Collaborate across disciplines, mentoring junior engineers and reviewing code for technical accuracy and architectural integrity.
• Guide iterative product development with a focus on continuous improvement and risk mitigation.
• Define and implement test strategies, including system-level and board-level validation procedures.

• 10+ years of embedded C development experience targeting RTOS environments.
• Mastery of low-level C programming, memory management, and optimization for resource-constrained systems.
• Deep expertise with PIC microcontrollers and peripheral interfacing.
• Demonstrated ability to develop, test, and maintain drivers for I2C, UART, SMBus, and similar protocols.
• Expertise in managing and evolving large, board-level codebases across multiple product generations.
• Successful track record of system-level integration, hardware bring-up, and troubleshooting.
• Ability to derive subtasks from complex requirements and manage task delivery.
• Strong documentation skills for technical requirements, interfaces, and iterative design changes.
• Experience in iterative and Agile development environments.

• Familiarity with other microcontroller families and cross-platform embedded development.
• Proficiency using oscilloscopes, logic analyzers, and other hardware debugging tools.
• Knowledge of CI/CD pipelines and automated testing for embedded systems.
• Experience mentoring other engineers or managing technical teams.
• Exposure to safety-critical or high-reliability system development.

• Exceptional problem-solving and analytical skills.
• Strong sense of ownership over project outcomes.
• Clear, concise communication style for both technical and non-technical audiences.
• Passion for clean code and technical excellence.
• Ability to work independently and also drive successful outcomes as part of a multidisciplinary team.

 Ideal candidates will play a key role in developing next-generation embedded products and be at the forefront of innovative hardware/software integration efforts.
