Firmware Engineer

Hoomanely; Panchkula; On-site; INR 1,800,000 - 2,400,000; Full time

Job summary

Hoomanely in India is seeking an experienced firmware engineer to build and maintain RTOS-based embedded software for sensor-driven hardware. You will work closely with the Lead Firmware Engineer to integrate sensors, manage power, and ensure reliable connectivity.

The role focuses on developing drivers for I2C/SPI/UART, BLE data transfer, OTA update support, and real‑world testing with oscilloscopes and logic analyzers to catch issues early.

Qualifications

• 4+ years of experience in firmware engineering for embedded devices.
• Experience with RTOS-based firmware development.
• B.Tech degree is required.

Responsibilities

• Develop and maintain RTOS-based firmware for embedded devices.
• Implement drivers for sensors over I2C, SPI, or UART and manage shared buses.
• Support BLE firmware for data transfer between devices and the cloud.
• Assist OTA update mechanisms and test rollouts before release.
• Debug hardware–firmware interactions using oscilloscope and logic analyzers.
• Write unit and hardware-in-the-loop tests to catch issues before field release.

Job description

We're looking for a firmware engineer to build and maintain reliable embedded systems for Hoomanely's sensor-driven hardware, working closely with the Lead Firmware Engineer across sensor integration, connectivity, and power management.

What You'll Do

• Develop and maintain RTOS-based firmware for embedded devices, keeping real-time performance stable
• Implement drivers and communication logic for sensors over I2C, SPI, or UART, and support arbitration across shared buses
• Support BLE-based firmware development for reliable data transfer between devices and the cloud
• Contribute to firmware-level battery charging safety, thermal cutoff logic, and clock stability under real-world conditions
• Support OTA update mechanisms, including testing rollout and rollback behavior before release
• Debug hardware-firmware interaction issues using tools such as oscilloscopes and logic analyzers
• Write and maintain unit and hardware-in-the-loop tests to catch issues before they reach the field

Required Qualifications

• 4+ years of experience
• Qualifying Degree: B.Tech

Why Join Us?

• Build firmware for hardware that's actually out in the field, on real dogs — not just on a bench
• Learn directly from the Lead Firmware Engineer while owning real pieces of the system
• Take ownership early, with a direct line to the people building the rest of the product
• Join a small, fast-moving team building a category-defining, sensor-driven product
