Mechanical Engineer II

About the role

Red 6 is an AR technology startup developing synthetic air combat training solutions. The Mechanical Engineer II will translate high‑level product needs into mechanical designs, collaborating with cross‑functional teams to create documentation, BOMs, and test plans.

Key responsibilities

• Lead mechanical engineering and design review activities within a cross‑functional team.
• Develop mechanical drawings, specifications, and review vendor proposals for compliance.
• Gather component‑level requirements and conduct R&D to identify optimal technologies within cost constraints.
• Apply engineering principles to optical and mechanical system design, including tolerance analysis.
• Drive design improvements addressing reliability and usability issues.
• Advance prototypes to production‑ready status and manage design‑development schedules.
• Perform simulation, modeling, testing, and structural analysis using hand calculations and FEA.
• Create production drawings with GD&T and ensure design‑for‑manufacturability.

Required profile

• Bachelor’s degree in mechanical engineering or related field, or equivalent experience.
• 2‑5 years of hands‑on product design and prototyping, especially in precision mechanisms, electromechanical or optical systems.
• Experience collaborating with industrial design, engineering, and research teams.
• U.S. citizenship required for security clearance eligibility.

Required skills

• 3D mathematics, numerical methods, modeling and simulation.
• Design‑for‑manufacturability (DFM) and design‑for‑assembly (DFA) with tolerance management.
• Finite element analysis (FEA) and computational fluid dynamics (CFD).
• Mechanical integration of PCBs, PCBAs, and flexible circuits.
• Production processes: plastic injection molding, casting, metal injection molding (MIM), machining.
• Geometric Dimensioning & Tolerancing (GD&T).
• Prototyping, test procedure creation, and verification activities.

What we offer

• Base salary $95,000‑$125,000 depending on experience.
• Full‑time benefits: 100% healthcare, dental, vision coverage for employees.
• Paid time off, vacation, sick leave, holidays, parental leave.
• Short and long‑term disability, flexible spending account, 401(k) plan.
• Voluntary worksite benefits and potential discretionary annual bonus.
