About The Position

Lyten is seeking an experienced Additive Manufacturing Technician III to join their AM production team. This role focuses on industrial FFF/FDM printing with engineering-grade and carbon-reinforced filaments, including Lyten's own materials. The technician will be responsible for the entire build process, from file preparation and machine setup to post-processing, part inspection, and verification. They will also be involved in troubleshooting failed builds, leading root cause analysis with engineering and quality, documenting fixes, performing preventive maintenance and calibration, installing and commissioning new machines, training team members, and developing documented, repeatable processes for scaling production. This is a hands-on, on-site role requiring production experience on industrial or production-grade printers.

Requirements

High school diploma or GED with 5+ years of hands-on experience in manufacturing, prototyping, or technical production, including at least 3 years running and maintaining industrial or production-grade FFF/FDM printers; OR Associate degree in manufacturing, mechanical, or engineering technology (or a related technical field) with 4+ years of hands-on experience running and maintaining industrial or production-grade FFF/FDM printers OR Bachelor’s degree (unrelated field) AND 3+ years of relevant experience in fast growth manufacturing or machining environment, data entry, or a related area
Proven track record of troubleshooting printers independently and getting them back into production.
Solid knowledge of engineering thermoplastics and reinforced filaments (e.g., nylon, PC, PEI, PEEK/PEKK, carbon-fiber-filled materials), including drying and print-setting tuning.
Ability to read engineering drawings and basic GD&T, and skill with precision measuring instruments.
Comfort with slicing and build-prep software, Microsoft Office, and ERP or MES systems for production records.
Clear communicator with the patience to train others and write procedures people can actually follow.

Nice To Haves

Experience with other AM methods, especially MJF, SLS, LPBF/DMLS, or large-format pellet extrusion.
Experience on industrial FFF platforms such as Stratasys, Markforged, BigRep, or similar production systems.
Post-processing experience with CNC machining, structural adhesives and bonding, or composites.
Background in motorsport, aerospace, or other high-performance manufacturing.
Basic CAD skills (e.g., SolidWorks, Fusion) for fixtures and minor part edits.
SME additive manufacturing certification or OEM operator and maintenance certificates.
Forklift certification.

Responsibilities

Set up and run industrial FFF/FDM printers, including bed preparation, nozzle and hotend changes, material loading, and pre-build checks.
Prepare and verify build files with engineering using slicing and build-prep software, confirming orientation, supports, infill, and process settings match the approved process.
Monitor builds, diagnose print defects, and adjust settings within approved limits; escalate anything outside them.
Plan and sequence builds across the printer fleet to keep production on schedule.
Install, set up, and commission new machines, including FFF printers and potentially new methods like MJF, SLS, LPBF/DMLS, and pellet extrusion, verifying they meet acceptance criteria.
Help evaluate new equipment and work with OEMs on site requirements, installation, and training.
Run test and qualification builds with engineering, record results, and turn them into work instructions and maintenance plans.
Own daily, weekly, and scheduled preventive maintenance on printers and support equipment.
Calibrate printers on a set schedule and after repairs or moves, and keep calibration records current.
Diagnose and fix mechanical, electrical, thermal, and firmware issues, and partner with OEM service on complex repairs.
Track machine uptime and recurring failures and recommend changes that improve availability.
Manage material inventory with lot traceability, including drying, moisture control, and sealed storage for hygroscopic engineering filaments.
Keep consumables stocked and flag shortages before they affect production.
As powder and pellet methods come online, set up and follow lot control, sieving, and reuse tracking for those materials.
Remove supports, sand, drill, tap, install threaded inserts, and finish parts to drawing requirements.
Prepare parts for downstream bonding, coating, composite work, and assembly.
As new methods are added, take on their post-processing steps.
Inspect parts using calipers, micrometers, height gauges, pin gauges, and visual standards, and record results.
Verify finished parts and first articles against drawings and specifications before release, including dimensional, visual, and fit checks.
Lead root cause analysis on failed builds, part defects, and equipment problems using structured methods.
Confirm that corrective actions work.
Keep complete build documentation so every part that goes on a car can be traced; open nonconformance reports and support disposition.
Follow the quality system and help strengthen it as production grows.
Train and mentor staff and sign off on their task proficiency.
Write and revise work instructions, maintenance procedures, and checklists.
Collect build and machine data that supports process development, qualification builds, and root cause investigations.
Take an active part in Lean, 5S, and safety improvement work.
Work safely around heated equipment, printer emissions, and the chemicals used in support removal and finishing, using ventilation and PPE as required.
As powder-based and metal systems come online, train on and follow safe powder handling practices.
Set the example for a stop-and-ask safety culture on the team.
