Senior Mechanical Design Engineer — Remote, Lead Projects

Synthires; California; Remote; USD 276,000 - 413,000; Full time

Job summary

Synthires is seeking a senior-level engineer contractor to drive complex mechanical engineering initiatives focused on AI training workflow challenges. You will translate objectives into precise mechanical requirements, lead multi-disciplinary teams, and ensure designs meet performance, manufacturability, and verification criteria.

Responsibilities include designing realistic projects, coordinating design, analysis, and manufacturing efforts, and performing root-cause analyses to resolve issues.

Qualifications

• 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, engineering analysis, and technical problem-solving.
• Practical experience with design for manufacturing and assembly (DFMA).
• Experience with technical verification through testing, failure investigation, and root-cause analysis.
• Ability to translate project objectives into engineering requirements, operating constraints, and measurable deliverables.
• Strong understanding of mechanical systems, manufacturing processes, and engineering validation methods.
• English proficiency at B2 level or higher.
• Excellent technical communication, analytical, and project leadership skills.

Responsibilities

• Design realistic engineering projects involving mechanical design, engineering analysis, manufacturing, and testing, incorporating relevant contributions from other technical disciplines.
• Translate project objectives into clearly defined mechanical design requirements, operating constraints, performance specifications, and measurable acceptance criteria.
• Break complex engineering problems into connected tasks with defined inputs, deliverables, dependencies, and expert responsibilities.
• Lead multidisciplinary engineering workflows and coordinate technical contributions across design, analysis, manufacturing, and testing teams.
• Evaluate mechanical designs for functionality, structural integrity, manufacturability, reliability, and compliance with engineering requirements.
• Apply design for manufacturing and assembly (DFMA) principles to assess design feasibility and production considerations.
• Review engineering calculations, technical documentation, design models, and analysis results for accuracy and completeness.
• Define technical verification and validation approaches to assess whether designs meet performance and operational requirements.
• Analyze testing results, investigate failures, and conduct root-cause analysis to identify design or manufacturing issues.
• Establish objective evaluation criteria for engineering solutions and technical deliverables.
• Identify design risks, technical constraints, and cross-disciplinary dependencies, and recommend appropriate corrective actions.
• Document engineering decisions, technical assumptions, design requirements, and evaluation standards clearly.
