Electronics Engineer – PCB Design

4 weeks ago

Ahmedabad, Gujarat, India Innovix Pro Full time
Job Overview

We are seeking a passionate and detail-oriented Electronics Design Engineer with strong expertise in PCB design, embedded systems, and hardware integration. This role is ideal for someone who thrives on transforming circuit-level concepts into reliable, production-ready hardware for cutting-edge robotic systems.

The ideal candidate will take ownership of schematic design, PCB layout, component selection, prototyping, and validation—forming the backbone of our hardware development for motor control and automation applications.

Key Responsibilities

1. PCB Design & Hardware Development

- Design multi-layer PCBs for motor controllers, sensor interfaces, and embedded control units.
- Create clean and optimized schematics using Altium Designer, KiCAD, or Eagle.
- Perform high-speed and power integrity layout for motor driver circuits, microcontroller boards, and power regulation modules.
- Incorporate EMI/EMC best practices into PCB design for noisy industrial environments.
- Select components based on performance, availability, and thermal/electrical constraints.
- Coordinate with fabrication vendors and oversee the assembly and bring-up of new hardware.
- Design for manufacturability (DFM) and testability (DFT).

2. Embedded Hardware Integration

- Develop control boards using microcontrollers like ESP32, STM32, Teensy, etc.
- Integrate motor drivers (e.g., DRV series, TMC series, Cytron, L298) with power supply and feedback circuits.
- Work on signal conditioning, level shifting, and protection circuitry.
- Collaborate with firmware engineers for pinout planning, peripheral interfacing, and board validation.

3. Motor Driver Circuit Design & Testing

- Support the development of control boards for BLDC, brushed DC, stepper, and servo motors.
- Validate motor performance with encoder feedback systems (e.g., magnetic encoders, SSI, incremental encoders).
- Test motor control boards under real load conditions, tuning for thermal and electrical efficiency.

4. Bench Testing & Debugging

- Test and debug hardware using oscilloscopes, logic analyzers, multimeters, CAN analyzers, and signal generators.
- Document test cases, hardware revisions, and performance reports.

Preferred Skills & Knowledge

- Solid grasp of PCB stack-up, grounding techniques, and analog/digital signal separation.
- Understanding of motor control electronics and sensor interfacing.
- Hands-on experience with SMT prototyping, soldering, and rework.
- Exposure to CAN, RS-485, UART, SPI, I2C hardware-level integration.
- Familiarity with thermal design considerations, heat dissipation, and board-level protection.
- Prior experience with robotics, AGVs, or mechatronic systems is a plus.

Tools & Technologies

- PCB Tools: Altium Designer, KiCAD, Eagle
- Microcontrollers: ESP32, Teensy 4.x, STM32, Atmega series
- Motor Drivers: DRV88xx, TMC2208/2130, Cytron, L298, A4988
- Firmware Tools: PlatformIO, Arduino IDE, STM32CubeIDE, Keil
- Debug Tools: Oscilloscope, Logic Analyzer, CANalyzer, Serial Plotter
- Version Control: Git, GitHub
