- Designs and develops new high-precision analog/digital PCBs for laser control systems using Eagle and KiCad.
- Leads hardware testing, failure analysis, and systems integration for all PCBs within high-power laser systems.
- Conducts component-level debugging on PCBs, tracing faults from power supply rails to communication lines (CAN, SPI) and sensor data (ADC/DAC).
- Identifies burned/damaged components, performs SMD/THT rework and soldering to repair and validate boards.
- Developed an advanced auto-alignment algorithm using Particle Swarm Optimization (PSO) and PID control in Embedded C. This firmware uses a 4-Quadrant-Diode (4QD) PCB’s ADC signals to control piezo mirrors, automatically maximizing the laser’s power position.
- Developed an Autonomous Laser Alignment System using a PIC18F26K83. Implemented a Bayesian Optimization algorithm to maximize optical power by controlling a 2-axis piezo inertia mirror mount.
- Designed a "Virtual Encoder" in software to track position for an open-loop system.
- Configured the Internal ADCC in Burst Average Mode to filter high-impedance photodiode noise.
- Interfaced with a PI E-870.41 driver using a custom 20kHz multiplexed pulse train.
- Developed a robust CAN Bootloader for the dual-core dsPIC33CH, enabling remote firmware updates. Solved deep-level bugs related to hardware timer conflicts, slave core fuse-bit mismatches, and CAN state management.
- Installs and integrates validated PCBs into the final laser systems, verifying all CAN, power, and I/O cabling and debugging any system-level hardware/software conflicts.
- Contributes to the development of the C++/Qt-based system control software, integrating CAN protocols to control and test all PCBs from a unified application.

About the technology
What it covers
Microcontrollers are small computing units built into products that must react quickly, reliably, and with low power use. They sit inside control systems, consumer devices, industrial equipment, and connected products. Searchers often use MCU or microcontroller unit when they mean the same thing.
Typical work
- Firmware for sensors, actuators, and control loops
- Bare-metal code or RTOS-based applications
- Peripheral integration for I2C, SPI, UART, CAN, and PWM
- Power management, timing, and startup behavior
- Debugging on real boards with logic analyzers and debuggers
Tools and ecosystem
Strong specialists know the target chip family, vendor SDKs, compilers, and flashing tools. They also understand datasheets, reference manuals, memory maps, interrupts, timers, and low-level driver design. Common work often touches ARM Cortex-M, STM32, NXP, Microchip, ESP32, or similar platforms.
When to bring in help
Companies bring in freelance expertise when a prototype must become production-ready, when a board changes late, or when an old firmware base needs cleanup. In Stuttgart, this often fits teams working near automotive, industrial, and hardware-focused product development. On-site time can help with bring-up; later work is often easy to handle remotely.
What strong specialists do
Good professionals test on real hardware, keep timing predictable, and write code that survives power loss, noisy signals, and long device lifecycles. They document pin use, boot flow, and error handling clearly. They also work well with electrical specialists and product teams to close gaps between schematic and firmware.
What to look for
- Experience with your exact MCU family or a close match
- Comfort reading schematics, datasheets, and errata
- Practical debugging across firmware and hardware
- Clear notes on tests, edge cases, and release steps
- Familiarity with your industry constraints and language needs in Germany
Frequently asked questions
Quick answers to the questions that come up most around Microcontroller.
A Microcontroller is used when a product needs local control, fast response, and low power use. It runs the logic that reads sensors, drives outputs, and manages device behavior in appliances, tools, vehicles, and industrial systems.
A Microcontroller usually combines CPU, memory, and peripherals on one chip, while a microprocessor is often a more general compute core that relies on external components. For embedded control, an MCU is usually the better fit because it is simpler to wire, power, and ship.
Bring in a Microcontroller specialist when you need firmware that must run on real hardware, not just in theory. It is especially useful for board bring-up, unstable prototypes, porting code to a new chip, or fixing timing and reliability issues close to release.
A strong Microcontroller freelancer should know C or C++, interrupts, timers, memory limits, and peripheral drivers. They should also be comfortable with debuggers, oscilloscopes, datasheets, and the hardware details that affect firmware behavior.
The MCU world often includes ARM Cortex-M chips, STM32, NXP, Microchip, ESP32, and similar families. Many projects also rely on vendor SDKs, RTOS options, bootloaders, and flashing tools tied to the chosen chip line.
Microcontroller work is often mixed. Code review, feature work, and documentation can be remote, while board bring-up, hardware faults, and lab debugging are easier on site. In Stuttgart, many teams prefer an initial on-site phase and then remote follow-up.
Look for Microcontroller code that is stable under reset, handles errors cleanly, and respects timing and memory limits. Good output includes clear tests, readable driver structure, and notes that explain hardware assumptions and failure cases.
No. Microcontroller projects usually run without a full operating system and focus on direct hardware control, while embedded Linux targets a much larger software stack. If your product needs tight timing, small memory use, or battery-friendly behavior, an MCU is often the better choice.
