About The RoleWe are looking for a
Chief Mechanical Engineer to serve as the highest-level technical authority on mechanical engineering and product architecture at ACS. This is a senior individual contributor role requiring deep hands-on expertise across electromechanical systems design, testing, and validation. You will provide technical direction across structural, thermal, motion-control, and manufacturing domains, drive architecture decisions, and ensure on-time delivery of complex, mission-critical defense products from concept through deployment.
What You'll Do- Serve as the mechanical engineering team's highest-level technical authority; provide direction and review complex electromechanical design decisions across structural, thermal, motion-control, and manufacturing domains.
- Oversee mechanical testing, validation, and qualification activities to ensure designs meet performance, reliability, environmental, and operational requirements.
- Own engineering execution from concept through deployment; partner with leadership to define priorities, timelines, and milestones, and ensure projects are delivered on schedule and within scope.
- Work closely with product, operations, and leadership to align engineering efforts with company objectives; establish and maintain engineering processes, design reviews, and documentation standards to support rapid development and long-term maintainability.
What You'll Need- 12+ years of mechanical engineering experience developing complex electromechanical systems; Bachelor's or Master's degree in Mechanical Engineering.
- Proven track record as a technical lead, principal engineer, chief engineer, or equivalent senior technical authority on electromechanical systems, robotics, autonomous systems, or complex defense hardware.
- Experience delivering products that operate in demanding environmental and operational conditions; strong project management instincts with the ability to balance speed, quality, and technical risk.
- Excellent written and verbal communication skills with the ability to clearly convey technical concepts to both technical and non-technical stakeholders.
You'll Stand Out- Prior experience in defense systems, robotics, autonomous platforms, or safety-critical environments.
- Deep expertise in precision mechanisms, motion systems, thermal management, ruggedized hardware, or high-performance electromechanical products.
- Experience building or scaling engineering teams in fast-paced startup environments.
