Role Title: Chief Engineer / Senior Mechanical Engineer

Role Type: Contractor

Location: Remote - US-based preferred; candidates with strong relevant experience worldwide considered.

our partner is looking for experienced Chief Engineers or Senior Mechanical Engineers to support an AI training project focused on complex, real-world engineering workflows. In this role, you will draw on your experience leading multidisciplinary engineering projects to design realistic tasks, coordinate contributions from domain experts, and define clear technical objectives and evaluation criteria. Your expertise will help improve how AI systems approach mechanical design, engineering analysis, and technical project execution.

Scope of Work

  • Design realistic engineering projects involving mechanical design, engineering analysis, manufacturing, and testing, with contributions from other relevant disciplines.
  • Translate project objectives into clear design requirements, operating constraints, and measurable acceptance criteria.
  • Break complex engineering problems into connected tasks with defined inputs, deliverables, dependencies, and expert responsibilities.

Requirements

  • Substantial professional experience as a Chief Engineer, Senior Mechanical Engineer, or in a comparable technical leadership role.
  • Proven experience leading complex engineering projects involving multiple technical disciplines.
  • Strong expertise in mechanical design and analysis, design for manufacture and assembly, and technical verification through testing and root-cause analysis.
  • English proficiency at B2 level or higher.

Preferred Qualifications

  • A relevant master's degree or PhD in Mechanical Engineering or a related engineering field.
  • Experience with CAD, finite element analysis, or other relevant engineering simulation tools.
  • Experience leading projects from initial concept through detailed design, manufacturing, testing, and delivery.
  • Experience in aerospace, automotive, robotics, industrial equipment, energy, medical devices, or other complex engineering environments.

This is a 100% remote contract role, open to applicants worldwide in the countries the employer accepts.

What to know before you apply

Pay
At the published rate, 10 hours a week would be about $2,000–$3,000 and 20 hours about $4,000–$6,000 before tax. Hours depend on the project, so treat this as a ceiling, not a promise.
Openings
30 openings means this is a high-volume project. You are not competing for one seat: if you pass the test, there is room for you.
Location
Open worldwide in the countries the employer accepts. Payments usually go out through services like PayPal or Wise, so check one of them works in your country.
Credentials
The listing asks for a PhD. Put it in the first line of your profile: reviewers screen for it before anything else.
Timing
This listing is new today. Projects can close once they have enough people, so it is worth applying while it is open.
Test tips for engineers
  • Check units, loads and code references in every answer.
  • Sketch the system or structure before judging the AI's description of it.
  • Name the standard (Eurocode, ASCE, IEC…) you are applying.
