An external electronics engineer,
without a hiring process
Need an electronics engineer for a project? At ProtoMakers one engineer, with 15+ years of experience and 200+ projects, owns the circuit, the PCB and the firmware, and works directly with you.
When companies turn to an external electronics engineer
- There is no electronics engineer on the team, and the project needs one
- The team is overloaded, and the product cannot wait for a hire
- You need an outside opinion on a schematic, PCB or code before a big decision
- There is a fault or an unstable prototype, and you need someone who understands both the hardware and the code
What the engineer does
- Specification, architecture and component selection
- Circuit design and PCB layout
- Firmware for STM32, ESP32 and Nordic
- Testing, debugging and documentation
- Support up to mass production
Why one engineer for hardware and firmware
Most hard bugs in an electronic product sit between the board and the code. When the same engineer did both, there is no argument between teams about whose bug it is, and the fault is found faster.
A small company: when it fits, and when it does not
At a small company you talk directly to the engineer doing the work, with no project manager or team lead in between. That is faster, cheaper and more personal. A project that needs dozens of engineers at once is a better fit for a large company, and we will tell you so in the first call.
Frequently asked questions
How is this different from hiring an engineer?
No hiring process, no onboarding and no commitment after the project ends. You get a senior engineer who starts right away, and you pay by stages.
Can we start with a small project?
Yes, and most companies do exactly that: a design review, diagnosing a problem or a proof-of-concept prototype. If it works, we continue.
Do you work with our suppliers and factories?
Yes. We adapt to the company's suppliers, tools and standards.
Who owns the schematics and the code?
You do. All files and source code are handed over to you.

Examples from the field
SightGuard: a home phototherapy device for dry AMD
- Challenge
- Light therapy works only when the LEDs deliver exactly the specified wavelength range and intensity, in every session and throughout the session, even when the device runs on a battery.
Multi-channel spot-welding controller
- Challenge
- Deliver pulses of up to 1500 A with precise timing, without burning parts on every pulse.
Automated cleaning for solar fields
- Challenge
- Manage cleaning units spread across an open solar field, with no communication infrastructure and no technician on site.
