Lead Firmware Engineer

Full-Time | Bengaluru, Work from Office

Qualifying Degree : B.Tech from a Tier 1 Institute | Experience : 10+ years

Note : Shortlisted candidates will complete a take-home assignment as part of the process.

About the Role :

We're looking for a senior firmware engineer who can independently own the reliability of Hoomanely's 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.
