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 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.
• Strong 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.
