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 without bricking devices. The ideal candidate will have experience leading firmware teams, making low-level architecture decisions, and shipping connected hardware to production in a fast-paced, sensor-driven environment such as wearables or IoT.

What You'll Do

- Architect and develop reliable, real-time firmware on an RTOS, optimized for determinism, power efficiency, and long-term field stability.

- Lead sensor and bus arbitration across I2C, SPI, and UART, preventing data collisions and timing failures under load.

- Own BLE firmware design, balancing continuous high-frequency streams with bursty, event-driven data without data loss.

- Design and harden OTA update pipelines, including canary rollouts, rollback, and boot-loop recovery for deployed devices.

- Manage firmware-level battery charging safety, clock tree stability, and thermal cutoff logic in collaboration with hardware teams.

- Take end-to-end ownership of firmware modules, balancing reliability, maintainability, and time-to-market.

- Establish and enforce firmware testing standards, including hardware-in-the-loop (HIL) and automated testing.

- Mentor firmware engineers,



conduct code reviews, and maintain high engineering standards.

- Collaborate with hardware, ML, and application teams in an Agile environment, including sprint planning.

Required Qualifications

- B.Tech in Electronics, Computer Science, or a related field from a Tier-1 institute (IIT, NIT, BITS Pilani, or equivalent) mandatory.

- 10+ years of proven embedded firmware development experience.

- Robust hands-on experience with RTOS-based firmware and communication protocols, including I2C, SPI, UART, and BLE.

- Experience designing OTA update systems with safe rollout, rollback, and failure recovery mechanisms.

- Solid understanding of clock trees, power and battery management, and sensor arbitration under real-time constraints.

- Proficiency in C and C++ for embedded and microcontroller-based systems.

- Experience with Agile methodologies, firmware architecture, and mentoring or leading engineers.

Preferred Qualifications

- Experience with thermal sensors, IMUs, or camera modules on embedded platforms.

- Experience shipping firmware for consumer hardware products at fleet scale.

- Familiarity with cloud platforms and device telemetry integration.

- Experience working in a startup or fast-scaling hardware environment.
