INGSOL Labs is hiring a Hardware Design Engineer to work on custom IoT and edge gateway hardware for industrial
applications. You'll work alongside senior hardware and firmware engineers on production hardware — not isolated
coursework — designing, bringing up, and debugging real boards from schematic to field deployment.
1. Schematic design and PCB layout for embedded/IoT boards (power, digital, mixed-signal)
2. Component selection with cost, availability, and industrial-grade (temperature, EMI/EMC) constraints
3. Prototype bring-up and debug using multimeter, oscilloscope, logic analyzer, JTAG/SWD
4. Interface design for industrial I/O: RS-485/RS-232, digital/analog I/O, Ethernet, USB
5. Write and debug low-level firmware for peripheral bring-up and board validation
6. Collaborate with the firmware/software team on hardware-software integration
7. Support design-for-manufacturing (DFM) and design-for-test (DFT) reviews, and coordinate with PCB fabrication/assembly vendors
8. Document design files, BOMs, and test procedures
Requirements
1. B.Tech/B.E. in Electronics, Electrical, Instrumentation, or related field (fresher to 2 years experience)
2. Working knowledge of KiCad or Altium (schematic capture and PCB layout)
3. Hands-on project experience with visible debugging effort on a bare-metal ARM microcontroller (STM32 or similar Cortex-M) — worked at the register/peripheral level, not just library-abstracted code
4. Embedded C/C++ firmware experience at the peripheral/driver level (GPIO, UART, SPI, I2C, ADC)
5. Solid fundamentals in digital/analog electronics, power supply basics, and microcontroller architecture
6. Comfortable reading datasheets and application notes independently.
Preferred Qualifications
1. Exposure to industrial protocols: Modbus, RS-485, CAN
2. Familiarity with ARM-based SoCs/SBCs (e.g., NXP i.MX series) and/or Intel x86 embedded SoCs (N-series, Atom x7000RE)
3. Embedded Linux basics (Yocto/Buildroot, image flashing/booting, device tree)
4. Windows IoT/Embedded basics (driver installation, COM/USB debugging)
5. RTOS experience (FreeRTOS)
6. Exposure to TSN (Time-Sensitive Networking), hardware watchdog configuration, or TPM (Trusted Platform Module)
7. Understanding of EMI/EMC and certification requirements (CE, UL)
8. Genuine interest in industrial automation and manufacturing
