Core Responsibilities

Primary Functions

  • Lead the end-to-end production of prototypes and short-run components by programming and operating CNC mills, lathes, routers and multi-axis machining centers, ensuring G-code optimization, correct fixture design, and on-machine verification to meet dimensional and surface finish specifications.
  • Plan, prepare and execute additive manufacturing builds (FDM, SLA, SLS, DLP, material jetting) including part orientation, support generation, resin/material selection, slicer/CAM settings and failure-mitigation strategies to maximize first-pass success and throughput.
  • Operate and program industrial laser cutters and engravers, set power/speed/kerf parameters, nest production layouts and perform routine optical alignment and lens cleaning to preserve cut quality and repeatability.
  • Develop and maintain CAD-to-CAM workflows (SolidWorks, Fusion 360, Rhino, Mastercam, Autodesk CAM) by creating robust, manufacturable models and extracting toolpaths, nesting, and post-processing scripts that reduce cycle time and scrap.
  • Design and fabricate custom jigs, fixtures, tooling and adaptive work-holding to enable repeatable machining, finishing and assembly processes for complex geometries and mixed-material assemblies.
  • Perform material characterization and selection for plastics, composites, metals and hybrid materials; establish print and machining settings, annealing/post-cure processes, and storage/handling protocols that preserve mechanical properties.
  • Implement and document post-processing and finishing operations (sanding, tumbling, vapor smoothing, resin washing, polishing, painting, heat treating, anodizing) to achieve specified aesthetic, mechanical and tolerancing requirements.
  • Maintain and calibrate precision measurement and metrology equipment (calipers, CMMs, height gauges, profilometers) and verify first-article inspections to ensure parts meet engineering tolerances and drawing callouts.
  • Troubleshoot equipment failures, electrical/mechanical issues, firmware anomalies and software interoperability problems; perform preventive maintenance and coordinate repairs with vendors to minimize downtime.
  • Establish and enforce shop safety procedures, laser and chemical safety protocols, PPE requirements, machine guarding and lockout/tagout processes in compliance with OSHA, local regulations and institutional policies.
  • Create and maintain detailed fabrication documentation: standard operating procedures (SOPs), work instructions, machine logs, maintenance schedules, tooling libraries, and digital build records for traceability and continuous improvement.
  • Collaborate with product designers, mechanical engineers and project managers to translate concept CAD into manufacturable components, provide design-for-manufacturability (DFM) feedback and iterate quickly to align with program milestones.
  • Manage inventory of raw materials, tooling, consumables and spare parts; forecast supply needs, negotiate with vendors and maintain vendor qualification records to support uninterrupted production runs.
  • Implement quality control systems and inspection plans, capture nonconformance data, lead root-cause analysis and corrective actions to reduce defect rates and improve process capability (Cp/Cpk).
  • Program and validate multi-axis toolpaths and robotic machining sequences for metal-cutting and hybrid manufacturing processes, including safe cell layout, collision checking and simulation-driven optimization.
  • Mentor and train junior fabricators, student workers and cross-functional team members in safe equipment operation, CAD/CAM best practices and prototyping workflows; run internal workshops to raise lab capability.
  • Evaluate and qualify new fabrication technologies, printers, cutters, materials and CAM software; run pilot projects, cost-benefit analysis and ROI assessments to scale tools that accelerate design iteration cycles.
  • Integrate digital fabrication processes with product development pipelines: version-controlled CAD repositories, build ticketing systems, BOM alignment and digital workorders to enable reproducible, trackable manufacturing.
  • Optimize part nesting, build packing and batching strategies for additive and subtractive processes to reduce material waste, shorten lead-times and lower per-part cost for low-volume production.
  • Support interdisciplinary research and development initiatives by developing bespoke processes (cast tooling, vacuum forming, thermoforming, composite layup and curing) and producing experimental test articles to validate new concepts.
  • Coordinate third-party manufacturing and finishing partners for specialized services (electroplating, heat treating, injection molding tooling) and manage quality audits and inspection criteria for outsourced components.
  • Monitor KPIs such as machine utilization, first-pass yield, lead-time, scrap rate and on-time delivery; prepare regular reports and present process improvement recommendations to engineering and operations leadership.
  • Ensure digital thread integrity by maintaining accurate build metadata (machine settings, material lot numbers, operator notes) in PLM/MES systems or organized lab management software to support product validation and certification.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
  • Provide technical support to cross-functional teams during design reviews and prototype validation sessions.
  • Assist procurement in qualifying consumables and negotiating service-level agreements with equipment vendors.
  • Help coordinate public-facing maker-lab user schedules and training sessions if the role supports community or academic labs.
