Avionics Hardware Engineer

Avionics Hardware Engineer

Flight Controller, GNSS and Embedded Systems

Location: Gurgaon, India (On-site)

Experience: 2 to 4 years (we weight a strong portfolio of self-built hardware over years of tenure)

Team: Hardware / Avionics, BharatRohan

Role Overview

BharatRohan builds UAVs for precision agriculture. Today, much of our flight-critical hardware - flight controllers, GNSS receivers, and carrier boards - is bought in. We are bringing that capability in-house: designing our own carrier boards to the open Pixhawk / Cube standard, building custom u-blox-based GNSS boards, porting ArduPilot / PX4 to our own hardware, and learning from teardowns of existing autopilots.

We are looking for an engineer who does not just integrate off-the-shelf modules, but who designs, builds, and brings up avionics hardware from scratch. If you have personally taken a board from schematic to flying hardware, this role is for you. This is a founding hardware role with genuine end-to-end ownership: schematic to PCB to bring-up

to firmware to field.

Key Responsibilities

Hardware and PCB Design

• Design multi-layer PCBs and schematics in Altium Designer (or KiCad) - working from IC datasheets and reference designs, not just wiring up ready-made modules
• Design custom carrier boards to the open Pixhawk / Cube (FMUv6) standard - connectors, power, and peripheral breakouts
• Design custom GNSS-and-compass boards integrating u-blox receivers (NEO-M9N, ZED-F9P), including the RF front-end (antenna matching, SAW filter, LNA, controlled-impedance routing)
• Own signal integrity, EMI / EMC, and ESD - especially GNSS coexistence alongside LTE modems and camera subsystems
• Prepare BOM and AVL, manage component sourcing and lifecycle, and drive design-for-manufacturing with PCB fab and assembly partners

Firmware and Board Bring-up

• Develop firmware in Embedded C and C++ on STM32 (ARM Cortex-M) using ChibiOS, NuttX, or FreeRTOS
• Port ArduPilot and/or PX4 to our boards (hwdef, bootloader, sensor drivers) and validate the full system
• Develop DroneCAN / UAVCAN peripheral nodes (GPS, compass, ESC, smart battery) and MAVLink integration
• Bring up new boards: validate power rails, debug buses with an oscilloscope, logic analyzer, and SWD / JTAG, and write drivers for IMU, barometer, magnetometer, and GNSS over I2C, SPI, UART, and CAN

Validation

• Analyze existing autopilot and GNSS hardware to inform our own designs - re-draw schematics, identify ICs, build BOMs, and analyze layouts (for interoperability and learning, designing to open standards)
• Perform fine-pitch rework (hot-air, BGA, microscope) for prototyping and debugging
• Define and run bring-up, functional, and environmental (vibration and temperature) test procedures, and design test jigs and fixtures

Ownership

• Take end-to-end ownership of deployed field hardware - reliability, performance, and OTA- supportable firmware
• Document your designs (schematics, interface control documents, bring-up notes) and collaborate with firmware, backend, mobile, and product teams

Required Skills (Must-have)

• Multi-layer PCB design and schematic capture in Altium Designer or KiCad
• Hardware design around STM32 / ARM Cortex-M from datasheets - power, clocking, decoupling, and layout
• Embedded C and C++ on both bare-metal and an RTOS
• Board bring-up and debugging with an oscilloscope, logic analyzer, and SWD / JTAG
• Solid working knowledge of I2C, SPI, UART, and CAN
• A demonstrable portfolio of boards you personally designed and brought up - GitHub, project links, photos, or shipped products
• B.Tech in Electronics and Communication or Electrical Engineering, or an equivalent practical track record

Strongly Preferred

• ArduPilot or PX4 board porting (hwdef) - ideally a board you have already ported
• DroneCAN / UAVCAN node design
• Redundant and efficient power-supply design
• RF and GNSS layout, and u-blox chip integration
• Reverse-engineering a PCB, or extracting and analyzing firmware
• Design-for-manufacturing experience and working with fab / EMS houses

Bonus

• RTK GNSS (ZED-F9P) and moving-baseline heading
• RF lab work (vector network analyzer, spectrum analyzer, near-field probes)
• MAVLink internals and Mission Planner / QGroundControl

What Makes You a Great Fit

• You have taken hardware from a blank schematic to a working board yourself
• You debug with a scope in one hand and a datasheet in the other
• You own problems end-to-end and document what you build
• You are excited to build India-made avionics for real-world agriculture

Why Join Us

• Build flight-critical hardware that flies over real farms, not demos
• Found our in-house avionics capability and own designs from concept to production
• Work across the full stack - PCB, RF, firmware, autopilot, and field
• A collaborative, innovation-driven engineering culture

How to Apply

Send your resume along with links to hardware you have built - GitHub, schematics or layouts,

ArduPilot / PX4 contributions, project writeups, or photos of boards you have brought up. Tell us

about one board you took from schematic to working hardware: what it was, and what broke along

the way.
