Senior Aircraft Loft Engineer - CAD & Surfaces

Haast Autonomous; Pendleton (OR); On-site; USD 120,000 - 180,000; Full time

Job summary

Haast Autonomous is seeking a Senior CAD Loft Engineer to own the master CAD model and outer mold line for our aircraft. You will convert airfoil data, packaging layouts, and aerodynamic inputs into precise, manufacturable geometry and deliver production-ready definitions for structures and tooling.

You will build robust parametric models, manage configurations, and collaborate with aerodynamics, structures, and manufacturing teams to ensure continuity and quality as we move from prototype

Qualifications

• At least two years of professional experience in aircraft lofting or airframe surface design.
• Experience developing the outer mold line or master geometry for a complete aircraft.
• Expert proficiency in CATIA, Siemens NX, Creo, or SolidWorks.
• Advanced capability in complex surfacing, multi-section lofting, guide-curve development, boundary surfaces, surface trimming, blending, and repair.
• Strong understanding of surface continuity, spline behavior, curvature control, and the relationship between aerodynamic intent and manufacturable geometry.
• Experience with aircraft coordinate systems, airfoil data, wing planforms, fuselage sections, aerodynamic intersections, and control-surface geometry.

Responsibilities

• Own and maintain the authoritative master CAD model and outer mold line for Haast aircraft.
• Develop complete aircraft lofts from airfoil coordinates, aerodynamic surfaces, station data, packaging envelopes, and configuration layouts.
• Create production-quality surfaces for the fuselage, wings, wing-body intersections, fairings, nacelles, booms, empennage, payload doors, access panels, and propulsion integrations.
• Establish aircraft coordinate systems, reference geometry, waterlines, buttock lines, fuselage stations, master sections, datums, and interface locations.
• Build robust parametric models using master sketches, skeleton models, guide curves, boundary surfaces, multi-section lofts, and top-down design methods.
• Maintain appropriate positional, tangent, and curvature continuity across complex aircraft surfaces.
• Evaluate surface quality using curvature analysis, zebra analysis, deviation checks, section cuts, and other CAD inspection methods.
• Convert outer-mold-line surfaces into manufacturable composite structures, skins, cores, bulkheads, ribs, spars, frames, and bonded assemblies.
• Develop accurate split lines, trim definitions, offsets, tooling surfaces, molds, plugs, fixtures, and assembly references.
• Ensure that aerodynamic surfaces remain controlled as structural, payload, propulsion, avionics, and manufacturing requirements evolve.
• Manage external references, model dependencies, naming conventions, configurations, revisions, and released CAD data.
• Identify and resolve surface gaps, discontinuities, intersections, minimum-radius problems, thickness conflicts, and non-manufacturable geometry.
• Produce detailed part models, assemblies, engineering drawings, interface-control drawings, GD&T, tolerance definitions, and bills of materials.
• Work closely with aerodynamicists, structural engineers, manufacturing partners, and the flight-test team to incorporate design changes without degrading the master geometry.
• Support fabrication and assembly by investigating CAD discrepancies, tooling issues, part-fit problems, and deviations from design intent.
• Help establish Haast’s standards for CAD architecture, geometric control, drawing release, and configuration management.
