Hardware & Embedded Systems Engineer

CETO Innovation is developing technology for predictive maintenance of district heating infrastructure. Our solution combines an in-pipe inspection probe, sensing technology, and predictive analytics to help utilities understand underground pipelines without excavation or interruption of normal operation. We are looking for a Hardware & Embedded Systems Engineer to help develop the next generation of CETO's inspection probe. Build compact, sensor-rich hardware that can move through district heating pipes, collect reliable inspection data, and support better maintenance decisions.

What you'll work on Design, build, and test compact in-pipe probe prototypes

Integrate ultrasonic sensors, visual inputs, motor drivers, and embedded electronics

Develop and validate small custom PCBs for CETO's probe electronics

Develop embedded firmware for sensors, actuators, communication, and control

Work on power, communication, signal integrity, thermal stability, and miniaturization

Support in-pipe locomotion, traction, actuator function, and tethered power/comms/retrieval

Translate system and customer requirements into practical engineering solutions

Plan hardware development, testing, and prototype iterations

Debug real hardware using test rigs, measurement tools, and structured experiments

Validate sealing, vibration resistance, pressure/temperature tolerance, robustness, and data transmission

Collaborate with software and ML engineers so the probe produces reliable inspection data

What we're looking for Hands-on experience developing and debugging physical hardware, prototypes, test rigs, robots, or mechatronic systems

Embedded firmware experience in C/C++ for STM32, ESP32, Arduino, or similar

Strong electronics fundamentals: schematics, sensors, actuators, drives, and circuit debugging with a multimeter

PCB design or schematic capture experience using KiCad, Altium, Eagle, or similar

Experience with UART, I2C, SPI, RS-485/Modbus, or CAN

Experience with motors, actuators, motor drivers, or compact electromechanical systems

Basic Linux experience, preferably Ubuntu

Experience with Git and GitHub

Ultrasonic sensing, NDT, robotics, ruggedized hardware, or pressure-resistant electronics is a plus

How we work You will join a small, hands-on startup team where everyone takes responsibility for their own work and is expected to show initiative. You should be comfortable working independently when needed, while collaborating closely with the team. In this role, you will work particularly closely with another engineer on the development, testing, and iteration of CETO's hardware system.
