Senior Manufacturing Engineer

Location: Shelburne, VermontDepartment: Engineering / OperationsReports To: Engineering Manager/ Operations Leadership Role OverviewAtlas Gunworks operates in a tight-tolerance, precision manufacturing environment where design intent must translate flawlessly into repeatable production execution.The Senior Manufacturing Engineer owns the development, validation, and optimization of manufacturing processes across machining, assembly, and finishing operations. This role drives fixture strategy, process capability, documentation rigor, and continuous improvement initiatives that directly impact throughput, cost, and product quality.This is a hands-on, floor-integrated engineering role requiring deep technical manufacturing experience, not theoretical engineering exposure. Core ResponsibilitiesManufacturing Process Development• Design, build, and validate end-to-end manufacturing processes• Establish process routing, sequence optimization, and production flow• Develop machining and assembly strategies aligned to tight tolerances• Monitor process stability and implement corrective improvements Fixture & Workholding Engineering• Design and implement precision fixtures and workholding solutions• Improve repeatability, setup reduction, and cycle efficiency• Collaborate with CNC programmers and machinists on tooling strategies• Validate fixture performance through production trialsTechnical Documentation & Work Instructions• Create detailed work instructions and visual standard work• Define tooling, consumables, and machine requirements• Maintain engineering documentation and revision control• Support controlled document release and change management processes CAD, Modeling & Drawing Management• Develop 3D models for fixtures, tooling, and process aids• Update engineering drawings and manufacturing prints• Apply GD&T principles for manufacturability and inspection alignment• Support tolerance stack-up analysis Additive & Laser Technology Integration• Utilize 3D printing for rapid prototyping and fixture development• Support laser marking / engraving process development• Identify additive manufacturing applications for efficiency gainsContinuous Improvement & Operational Excellence• Lead cost, scrap, and cycle-time reduction initiatives• Drive OPEX and Lean manufacturing projects• Conduct root cause analysis and implement corrective actions• Support lights-out machining and automation initiatives Cross-Functional Execution• Partner with Design Engineering, Quality, and Production teams• Support NPI launches and process readiness• Manage engineering task execution within dynamic production schedules• Provide technical mentorship to junior engineers and techniciansRequired Qualifications• Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, or related field (or equivalent experience)• 8+ years of manufacturing engineering experience• Direct experience in tight-tolerance machining environments• Fixture and workholding design expertise• Strong GD&T application knowledge• Experience creating work instructions and process documentation• Hands-on metals manufacturing experiencePreferred Qualifications• Firearms, aerospace, or medical device manufacturing exposure• Additive manufacturing / 3D printing experience• Laser marking / laser engraving process knowledge• CAM programming familiarity• Automation integration exposure• Lean / Six Sigma certificationSuccess ProfileThe right candidate:• Understands machining physics, not just engineering theory• Designs processes that scale, not just function once• Is equally effective in CAD and on the shop floor• Identifies waste and eliminates it structurally• Operates with ownership in high-accountability environments
