Patronus AI is a behavioral research lab for artificial intelligence that studies where models and agents fail and how to improve their judgment. They build realistic, domain-specific simulated environments and world models where agents can practice decision-making under fragmented information, conflicting requests, and unstated requirements; analyze agent mistakes; and create training data, benchmarks, and tests (e. g. , TRAIL, MEMTRACK) to improve AI reliability and alignment. The company emphasizes fundamental research, publishes on arXiv, and provides resources such as RL environments, testing frameworks, and domain guides. Their site references enterprise-relevant compliance (SOC 2, HIPAA, TISAX).

📋 Description

• Help the research team understand how mechanical engineering work is performed in practice • Design realistic mechanical engineering tasks that qualified professionals can solve and current AI models get wrong • Create working documents such as drawings, CAD models, bills of materials, hand calculations, simulation reports, load calculations, equipment schedules, process sheets, tooling drawings, and test reports • Write task requests specifying deliverables and how uncertainty and justified assumptions should be handled • Solve tasks end to end and document reference solutions with reasoning • Write precise scoring criteria, including acceptable alternatives and numerical tolerances • Check personal and peer tasks for technical accuracy and ambiguity • Incorporate reviewer feedback within agreed turnaround times and flag guideline gaps or edge cases • Explain workflows, documents, responsibilities, and failure points to the research team • Review research-created scenarios and documents and flag anything unrealistic to practitioners

🎯 Requirements

• 3+ years of hands-on experience in mechanical design or structural analysis, thermal/fluid/HVAC engineering, or manufacturing/tooling engineering • Working command of relevant standards, methods, and codes, including examples such as ASME Y14.5 and GD&T, ASHRAE and ASME codes, heat transfer and fluid sizing methods, or design for manufacturing and process capability • Strong calculation and spreadsheet skills • Habit of checking every unit, assumption, and load case • Clear, precise writing in professional English • Ability to work independently and asynchronously against deadlines • Human-authored work only; LLM-generated content is not permitted • Original tasks and solutions; no copying from published or easily searchable sources • No use of real employer, client, or supplier data, drawings, or designs, or anything covered by an NDA or export control • Applicants must complete a short AI interview, resume review, and one paid trial task • Prior AI evaluation, exam question, case study, or training-material experience is nice to have • Familiarity with how AI models fail is nice to have

🏖️ Benefits

• Pay of $50 to $150 per hour • Bonus for each accepted task for projects paid per task • Strong performers may move up within the pay range or onto productivity-based pay • Paid trial task • Fully remote, asynchronous work • 10 or more hours per week • Rolling start
