Experience: 0–2 years (Freshers with solid project portfolios or collegiate racing/robotics backgrounds are strongly encouraged to apply)

Notice Period: Immediate joiners only (maximum 7–15 days notice)

About the Role:
We are seeking a hands-on Embedded Systems Engineer to take ownership of end-to-end hardware development, PCB layout, and firmware architecture for our micro-mobility and smart hardware platforms.

You will work directly on the core electronic nervous system of our vehicles and connected devices—from schematic design and multi-layer board routing in KiCad to writing production-grade firmware in ESP-IDF/C++, lab bench bring-up, and real-world vehicle testing.

Key Responsibilities:
PCB & Hardware Engineering: Design, layout, and validate 2-to-4 layer boards using KiCad. Select components,



manage BOMs, optimize for DFM/DFA, and build custom power distribution and peripheral circuits.

Firmware Development: Develop robust, non-blocking firmware for microcontrollers (primarily ESP32 and ARM Cortex-M) leveraging FreeRTOS tasks, queues, timers, and state machines.

Peripheral & Communication Protocols: Integrate and debug hardware communication interfaces including I2C, SPI, UART, CAN bus, ADC sensor feeds, and cellular/GPS (4G LTE/GNSS) modules.

Bench Bring-Up & Diagnostics: Solder, assemble, and test prototype boards in the lab. Diagnose hardware faults, noise issues, signal integrity, and power anomalies using multimeters, oscilloscopes, and logic analyzers.

Field Validation & Documentation: Collaborate on vehicle-level testing, thermal performance, and vibration reliability. Maintain structured Git repositories, board revisions, and hardware design documentation.
