Chief Engineer / Senior Mechanical Engineer

$200–300/hr

rate as listed

Workload: ~15h/week
Engagement: Project-based
Location: Worldwide
Field: Engineering

Design realistic AI training tasks based on complex mechanical engineering projects, from requirements definition through manufacturing and testing. The work calls for senior technical leadership experience across multiple engineering disciplines.

The work

You will design realistic engineering projects that test how AI systems handle mechanical design, engineering analysis, manufacturing and testing. Day to day, this means translating project objectives into design requirements, operating constraints and measurable acceptance criteria, then dividing the work into connected tasks with clear inputs, deliverables, dependencies and responsibilities for contributing domain experts.

What the platform screens for

The screening is likely to focus on specific projects you have led as a Chief Engineer, Senior Mechanical Engineer or comparable technical leader. Expect follow-up questions about multidisciplinary coordination, mechanical design and analysis, design for manufacture and assembly, verification testing and root-cause analysis. English proficiency at B2 level or higher is required. A relevant master's degree or PhD, experience with CAD or finite element analysis, full product lifecycle leadership and work in complex engineering environments are preferred qualifications.

Practical details

This is a remote contractor role. US-based candidates are preferred, while candidates worldwide with strong relevant experience are also considered. The listing does not specify a weekly workload, working hours or whether delivery is fully asynchronous, so candidates should be ready to state their availability, time zone and ability to meet review or coordination windows. Pay band: $200–300/hr

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 your experience reflects chief-level or senior mechanical engineering ownership rather than participation without decision authority.
A strong answer: Use one verifiable project and specify the product or system, disciplines involved, your formal role, major decisions, constraints and delivered outcome. Clearly separate your own authority from the work performed by the broader team.
Where people lose it: Candidates lose points by describing the team's achievements without identifying which requirements, tradeoffs or technical approvals they personally owned.
