Job description

About Bota Systems

Bota Systems AG is a Zürich-based ETH spin-off building high-precision 6-axis force-torque, torque and tactile sensors — a sensing platform for physical AI. Inside every sensor is compact, low-noise electronics and embedded firmware that turn tiny strains into fast, reliable force data for robots.

We are hiring a Junior Embedded Systems & Electronics Engineer to help develop and improve that electronics and firmware as our product range and volumes grow.

The role

You will work alongside experienced engineers on real products from day one, learning across firmware, hardware and testing, and growing your responsibility as you go.

Key responsibilities

Embedded firmware

• Develop, test and maintain firmware in C/C++ for the microcontrollers in our sensors.
• Implement and improve signal acquisition, filtering and calibration routines.
• Work on communication interfaces such as EtherCAT, CAN, USB and serial.

Electronics hardware

• Work closely with the team in Altium on schematic design and PCB layout for new and existing sensor electronics, including design reviews and shared component libraries.
• Assemble, solder, rework and test prototype boards; bring up, debug and validate them in the lab.
• Help optimize electronics for noise, size, cost and manufacturability.

Testing and production support

• Build and improve test setups and scripts for development, calibration and end-of-line testing.
• Analyze field and production issues and help find root causes.
• Document designs, firmware releases and test procedures clearly.

What success looks like after 12 months

• You have shipped firmware features or fixes that run in customers' sensors.
• You have brought up and validated at least one new or revised PCB.
• Test setups you built or improved are in use in R&D or production.
• You work independently on well-defined tasks and know our product architecture well.

Who you are

Must have

• Degree in electrical engineering, electronics, mechatronics, computer engineering or similar (recent graduates welcome).
• Strong hands-on soldering skills: confident with through-hole and fine-pitch SMD soldering and rework, and with testing and debugging boards using oscilloscopes, multimeters and debuggers.
• Altium Designer experience: schematics and PCB layout, and comfortable working collaboratively on shared Altium projects (version control, design reviews, shared component libraries).
• Solid C/C++ skills for embedded systems (e.g. ARM Cortex-M / STM32).
• Good understanding of analog and digital electronics.
• Curious, hands-on and eager to learn; you take ownership of your tasks.
• Fluent English; German is a plus.

Nice to have

• Knowledge of industrial communication protocols (EtherCAT, CAN) or RTOS.
• Experience with signal processing, sensors or low-noise analog front ends.
• Python for test automation and data analysis.
• Projects from studies, internships or hobbies you can show us.

What we offer

• Real responsibility on products used by leading robotics companies.
• Mentoring from experienced engineers and a steep learning curve across firmware, hardware and testing.
• A small, ambitious team at the forefront of physical AI and robotics.
• Competitive salary and employee participation.
