Work History
Finishing Technician II
Custom Microwave Inc. (acquired by Vitesse / Lyntris)
Longmont, CO
02.2022 - Current
- Perform critical post-processing on metal 3D-printed parts and machined parts, executing hand-finishing, precision deburring, blending, and polishing to achieve strict aerodynamic and mating-surface tolerances.
- Perform high-precision mechanical assembly, structural adhesive bonding, and integration of flight-ready RF components and antennas for premier national security and spaceflight programs, including NASA, Northrop Grumman, Maxar, Tendeg, and Tomorrow.io.
- Execute complex, high-reliability torquing sequences and mechanical fastening to exacting engineering tolerances to ensure structural integrity under extreme launch and spaceflight environments.
- Apply specialized structural adhesives and chemical bonding agents to delicate composite, metallic, and RF elements.
- Interpret complex engineering drawings and GD&T specifications to ensure 100% dimensional compliance prior to final shipping.
- Serve as the final line of defense for Quality Assurance (QA) and Quality Control (QC), identifying and mitigating upstream fabrication anomalies to protect mission success.
- Maintain a sterile, ESD-safe, and FOD-free (Foreign Object Debris) environment to safeguard high-value, static-sensitive flight hardware.
- Document detailed build metrics, adhesive cure cycles, and serialization to maintain strict AS9100 aerospace traceability.
Blade Repair Technician II
