Job description

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

Required Qualifications

• 12+ years of experience
• B.Tech from a Tier 1 Institute

Why Join Us?

• Own firmware reliability for a category-defining, sensor-driven product — not a legacy stack
• Solve the hardest low-level problems in pet health hardware: real-time sensing, connectivity, fleet safety
• Take full ownership from day one, with a direct line to hardware, ML, and founding leadership
• Build the team you wished you'd had — hire, mentor, and set the bar
