Firmware Developer

Pinetics; Pune District; On-site; INR 600,000 - 1,200,000; Full time

Job summary

Pinetics is seeking a hands-on Firmware Developer to write clean, reliable C for microcontrollers and own the module end-to-end—from development to testing and documentation. You’ll build firmware for medical devices, industrial systems and IoT hardware, where hardware is tangible and bugs can cost a field return.

You will read schematics, participate in peer reviews, and implement robust, interrupt-driven code. Bring-up and debugging with the hardware team are integral to this role.

Qualifications

• B.E./B.Tech./M.E./M.Tech in Electronics or equivalent.
• 2–5 years firmware development experience.
• Good verbal and written English.

Responsibilities

• Develop firmware from driver level to application logic.
• Write and maintain drivers for GPIO, SPI, I2C, UART, ADC, DAC, timers, displays.
• Design ISR-based interrupt handling and bring-up with hardware team.
• Unit test firmware and fix issues before hand-off.
• Document interfaces and keep status updated.

Job description

We are looking for

A hands-on Firmware Developer who writes clean, reliable C on microcontrollers and owns their module end to end: development, testing, debugging and documentation. You will build firmware for real products - medical devices, industrial systems and IoT hardware - where your code runs on hardware you can hold, and a bug can cost a field return.

The person we are looking for tests what they write before calling it done, reads a schematic rather than waiting for someone to explain the board, and treats a peer review - given or received - as a way to make the product better, not a formality.

Should have the following responsibilities and background

1. Firmware Development

• Develop firmware as per the customer’s requirements, from driver level to application logic.
• Write and maintain drivers for common peripherals: GPIO, SPI, I2C, UART, ADC, DAC, timers, displays and memory devices.
• Design interrupt-driven behaviour correctly: ISRs, priorities, shared-data protection.
• Participate in board bring-up with the hardware team and help isolate hardware-firmware issues on the bench.

2. Quality and Testing

• Unit test the firmware you develop and fix what the tests find before hand-off.
• Debug systematically using JTAG/SWD debuggers, logic analysers and oscilloscopes.
• Review a colleague’s firmware module the way you would want yours reviewed: thoroughly and constructively.
• Adhere to the project’s quality processes: coding guidelines, version control discipline and release hygiene.

3. Delivery and Documentation

• Follow committed timelines and flag risk early - a slip reported on the day it is discovered is a plan; a slip reported at the deadline is a surprise.
• Document your modules so another engineer can pick them up: interfaces, assumptions, known limitations.
• Keep task status current so the Tech Lead never has to chase you for an update.

Technical Skills Required

• C Programming: Proficient, hands-on C on microcontrollers; ARM Cortex-M preferred (STM32, NXP, ESP32 or similar).
• Peripherals: Practical interfacing experience: GPIO, SPI, I2C, UART, ADC, DAC, timers, displays, memory devices.
• Interrupts: Conversant with interrupts and ISRs: latency, priorities, race conditions and safe shared-data handling.
• Bring-up & Debug: Board bring-up participation; debugging with JTAG/SWD, logic analysers, oscilloscopes and multimeters.
• Hardware Literacy: Can read schematics and understand discrete components, microcontroller circuits and memory interfaces.
• Version Control: Git-based workflow: branches, reviews, meaningful commits.

Preferred Skills (Added Advantage)

• C++, ARM Assembly, RTOS (FreeRTOS or equivalent), Embedded Linux.
• Networking and connectivity protocols: TCP/IP, MQTT, BLE, Wi-Fi.
• Exposure to IoT or IoMT (Internet of Medical Things) products, or regulated development such as ISO 13485 / IEC 62304.
• Experience in a product design services or contract development environment.

Qualifications

• B.E. / B.Tech / M.E. / M.Tech in an Electronics-based branch or equivalent.
• 2 to 5 years of experience in firmware development.
• Good verbal and written communication in English.

What Success Looks Like

• Your modules pass review and integration the first time far more often than not.
• Bugs found in your code are fixed with root cause understood, not patched over.
• The hardware team asks for you by name for bring-up support.

Remuneration & Work Location

• CTC Range: As per industry standard for relevant experience.
• Pune, Wakad Office.
