Hardware and Electrical Designer

We are looking for a 𝗛𝗮𝗿𝗱𝘄𝗮𝗿𝗲 𝗮𝗻𝗱 𝗘𝗹𝗲𝗰𝘁𝗿𝗶𝗰𝗮𝗹 𝗗𝗲𝘀𝗶𝗴𝗻𝗲𝗿. You'll build hardware design and debugging tasks around a board or electrical system you have worked on, so a leading AI company can measure how well models handle real embedded engineering problems. 𝗘𝗻𝗴𝗮𝗴𝗲𝗺𝗲𝗻𝘁 𝗱𝗲𝘁𝗮𝗶𝗹𝘀:

• Location: Gothenburg
• Working model: Hybrid
• Start date: ASAP
• Employment type: Freelance – hourly rate: $70–90 (paid per accepted task)

𝗥𝗲𝘀𝗽𝗼𝗻𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝗶𝗲𝘀:

• Build a benchmark environment around a board or electrical system you have designed or debugged
• Include schematics, layout excerpts or Gerbers, the BOM, component datasheets, measurement data, and the design constraints (cost, size, temperature, standards)
• Provide measurements as data files – scope captures as CSV, thermal readings as tables, EMC scans as frequency and level data – with images as supporting material
• Set up the tools the work needs – ngspice or another SPICE simulator, KiCad, Python, PDF tools
• Write five or more tasks, each built on a design decision or failure on that board (e.g. a regulator that oscillates at light load, filter values that push conducted emissions over the limit after a layout change, a component that derates past its limit inside the enclosure)
• Frame each task so the model must run calculations or simulations and produce answer.json with the faulty component or net, corrected component values, a part chosen from a supplied shortlist, and computed margins (phase margin, derated current, junction temperature or similar)
• Write a hidden marking script that checks each value within a set tolerance and runs a supplied SPICE netlist with the proposed values, scoring 0.0 to 1.0
• Design tasks around a part that looks right on paper but breaks a datasheet limit once temperature, ripple or enclosure airflow is applied
• Supply your own answer (scoring 1.0) and a naive answer a competent engineer might give first (scoring below 0.3)

𝗤𝘂𝗮𝗹𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀:

• Hands-on experience designing or debugging boards or electrical systems
• Strong command of component selection and datasheet limits, including temperature, ripple and current derating
• Experience with power supply stability, phase margin and thermal analysis
• Working knowledge of EMC and conducted emissions measurement
• Able to work from schematics, layout files or Gerbers, and BOMs
• Comfortable with ngspice or another SPICE simulator and KiCad
• Python skills to write automated marking scripts

𝗡𝗲𝘅𝘁 𝘀𝘁𝗲𝗽𝘀:

• Press "Apply"
• We will review your application
• If qualified, you will be accepted into the network and can be considered for this and similar positions & projects

We can only accept candidates that are willing to work as individual contractors / freelancers.
