About this role

From the Ethos listing

We’re working with a leading AI lab that needs experienced mechanical design engineers to review a set of engineering drawing packages and CAD models for quality and realism.

Each package is a small mechanical product: engineering drawings, part and assembly models, a bill of materials etc. Your job is to review it the way a drawing-office checker would and tell us whether it is complete, consistent and something a real engineering team would issue.

What you’ll do

• Check drawings for completeness and ambiguity: views, dimensions, datums, tolerances and notes
• Judge whether the design is realistic: manufacturable parts, sensible fits and hardware, mechanisms that work as described
• Check CAD models and feature trees against the drawings and the parts list
• Write short, specific findings with a clear pass / fix / reject call

Common questions

How and when does Ethos pay experts?

Within 30 days of invoice submission after a project closes. That net-30 schedule is standard for enterprise expert networks, but it's slower than the weekly payouts some AI training platforms offer, so plan your cash flow around it.

Is Ethos regular AI training work like rating chatbot responses?

No. Ethos is an expert network. AI labs, investment funds and large companies pay for your domain knowledge (deal analysis, clinical reasoning, legal logic, financial modeling) in three formats: multi-week consulting engagements, 30 to 60 minute advisory calls, and research surveys. Listings like this one are the AI-lab engagements, where you write or review expert material for a model.

How many hours a week is this Mechanical / CAD Design Engineer, AI Task Reviewer work?

Up to 10 hours a week. At $100/hr that is up to $1,000 a week. You set your own hours.

What specific skills does this listing call for?

Coding is named directly in the listing. If you don't have hands-on experience with this, expect the screening process to test for it directly rather than accepting adjacent experience as a substitute.

How much does this specific role pay?

This listing is posted at $100/hr, an hourly rate. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.

What happens when I click Apply on this listing?

The link opens Ethos's sign-up. There is no form for this listing: Ethos's AI interviewer asks about your career in a 5 to 15 minute call, builds your profile from it, and then matches you to projects like this one. Keep your CV open and cover the experience the Qualifications above ask for.

Who built Ethos and is it legitimate?

Yes. Ethos was founded in London in 2024 by James Lo (McKinsey, SoftBank Vision Fund) and Daniel Mankowitz (Google DeepMind research scientist and lead author of AlphaDev). It raised a $22.75M Series A led by a16z in May 2026, with General Catalyst and XTX Markets participating, and works with AI labs, private equity firms, hedge funds and consultancies.
