About the role

Key responsibilities & impact
  • Apply hands-on mechanical engineering expertise to technically complex tasks involving physical systems and products
  • Review and evaluate mechanical designs, engineering analyses, simulation results, test methodologies, and troubleshooting approaches
  • Analyze trade-offs involving structures, materials, thermal performance, mechanical design, dynamics, vibration, controls, reliability, and manufacturability
  • Assess the technical correctness and practical feasibility of engineering solutions
  • Identify incorrect assumptions, unrealistic boundary conditions, design deficiencies, failure modes, and implementation or reliability risks
  • Develop or review rigorous engineering problems, reference solutions, evaluation criteria, and technical documentation
  • Apply practical experience in design, simulation, prototyping, hardware integration, testing, validation, qualification, debugging, and manufacturing
  • Provide clear technical feedback grounded in engineering experience and established principles
  • Contribute to AI research projects focused on training and enhancing AI systems at Mercor, which partners with AI labs and enterprises

Requirements

What you’ll need
  • 5+ years of professional mechanical engineering experience
  • At least 3 years of recent, actively hands-on experience in hardware development, analysis, testing, validation, integration, bring-up, or troubleshooting
  • Experience as the responsible engineer for real hardware or physical systems, owning portions of the engineering lifecycle from requirements and analysis through design, prototyping, testing, validation, qualification, and manufacturing readiness
  • Deep technical expertise in at least one core domain: structural/stress analysis and FEA; thermal analysis, heat transfer, and thermal management; mechanical design and product development; or dynamics, vibration, mechanisms, and controls
  • Strong command of materials, loads and boundary conditions, structural margins, fatigue, thermal constraints, tolerances/GD&T, component selection, reliability, manufacturability, system integration, and engineering failure-mode analysis
  • Hands-on experience analyzing, testing, debugging, and validating physical hardware
  • Experience with CAD/CAE, FEA, CFD/thermal simulation, dynamic or controls simulation, test instrumentation, data acquisition, and structured root-cause analysis
  • Experience developing hardware in real-world product or manufacturing environments
  • Ability to clearly explain technical decisions, design trade-offs, test results, and failure mechanisms
  • Experience working for a company that designs, builds, tests, and manufactures physical hardware products or systems is strongly preferred
  • Must not require H1-B or STEM OPT support
