Lead Firmware Engineer

About the Role

We're looking for a senior firmware engineer who can independently own the reliability of embedded systems — from real-time sensor arbitration on shared buses to fleet-wide OTA delivery that never bricks a device. You've led firmware teams, driven low-level architecture decisions, and shipped connected hardware to production in a fast-paced, sensor-driven environment — pet wellness, wearables, or IoT.

What You'll Do

• Architect and build reliable, real-time firmware on an RTOS, tuned for determinism, power efficiency, and long-term field stability
• Lead sensor and bus arbitration across I2C, SPI, and UART — no data collisions, no timing failures under load
• Own BLE firmware design, balancing continuous high-frequency streams with bursty event-driven data, without loss
• Design and harden OTA pipelines — canary rollouts, rollback, boot-loop recovery — for a live device fleet
• Own firmware-level battery charging safety, clock tree stability, and thermal cutoff logic, working closely with the hardware team
• Take end-to-end ownership of one or more firmware modules, balancing reliability, maintainability, and time-to-market
• Set and enforce firmware testing standards, including hardware-in-the-loop and automated testing
• Mentor firmware engineers, review code, and raise the engineering bar across the team
• Work in an agile environment alongside hardware, ML, and app teams — sprint planning included

You Might Be a Fit If…

• You have a B.Tech in Electronics, Computer Science, or related field from a Tier 1 institute (IIT, NIT, BITS Pilani, or equivalent) — mandatory
• You have 10+ years of proven embedded firmware experience
• You have strong hands-on experience with RTOS-based firmware and protocols including I2C, SPI, UART, and BLE
• You've designed OTA update systems — safe rollout, rollback, and recovery from failure states
• You have a solid understanding of clock trees, power and battery management, and sensor arbitration under real-time constraints
• You're proficient in C and C++ for embedded and microcontroller-based systems
• You're familiar with Agile methodologies, with a track record of leading or mentoring engineers
• Bonus: experience with thermal sensors, IMUs, or camera modules on embedded platforms
• Bonus: shipped firmware for a consumer hardware product at fleet scale
• Bonus: familiarity with cloud platforms and device telemetry integration
• Bonus: prior experience in a startup or fast-scaling hardware environment

Pay: Up to ₹5,000,000.00 per year
