Build reproducible electrical engineering tasks and reference solutions for evaluating AI systems across circuits, power electronics, controls, and infrastructure. The work combines native simulation artifacts, engineering judgment, debugging, and automated verification with explicit units and tolerances.

Contributors develop realistic engineering tasks in areas such as circuit and PCB design, power electronics, power systems, embedded systems, and industrial controls. Day-to-day work may include creating schematics, SPICE netlists, component models, control logic, operating conditions, parameter sweeps, transient or steady-state analyses, and fault cases.

Each task needs a reference solution and measurable checks for quantities such as voltage, current, efficiency, losses, timing, stability, protection behavior, and design constraints. Contributors package model files, dependencies, scripts, assumptions, and results so another engineer can reproduce the analysis, then test the verifier against both correct and deliberately incorrect cases. Standards may follow a US track using NEC / NFPA 70, NESC, or IEEE, or an international track using IEC, depending on the problem.

The platform is likely to screen for verifiable project ownership, recent hands-on use of relevant engineering software, and the ability to explain model assumptions under technical follow-up. Candidates should also expect scenarios involving convergence failures, physical plausibility, numerical tolerances, safety margins, Python-based automation, and diagnosis of AI-generated designs or simulation setups.

Practical logistics: The listing does not specify remote status, asynchronous scheduling, or typical weekly hours, so candidates should confirm each with Mercor. The observed band is not guaranteed.

Interview prep — 10 questions

Matched to what this platform's screening actually measures. Answer each out loud in 60–90 seconds: claim → concrete example → implication.

What it tests: This tests whether the claimed experience involved accountable engineering decisions rather than observation, support work, or purely academic exercises.
A strong answer: Identify the system, your exact ownership boundary, the tools and artifacts you produced, and a quantified acceptance result or failure you resolved. Be ready to separate your work from the wider team's contributions.
Where people lose it: Candidates lose points by describing a team project without identifying which schematic, model, control loop, test plan, or sign-off decision they personally owned.

Summary, eligibility guidance and screening preparation are prepared by Sidequest from the platform's posting. Check the source listing before applying.
