About the Role

Join Zipline’s Long Range Platform team as an owner-oriented Mechanical Engineer to design, validate, and deliver critical airframe and electromechanical hardware for long-distance autonomous delivery aircraft. This role focuses on reducing aircraft weight, increasing reliability in harsh conditions, and enabling higher sortie rates, with end-to-end hardware responsibility from concept to sustainment.

Responsibilities

  • Own specific Long Range mechanical subsystems and serve as the primary technical lead from concept to sustained production.
  • Translate operational and fleet requirements into quantitative mechanical performance targets and design architectures.
  • Produce and iterate detailed CAD models, tolerance stacks, GD&T, and manufacturing drawings for volume production.
  • Run first-principles analysis and engineering simulation, validating with bench tests and flight-representative test rigs.
  • Prototype rapidly, lead hands-on build-test-iterate campaigns, and produce test plans with go/no-go metrics.
  • Define and own verification matrices, failure modes & effects, and corrective actions through qualification and production ramp.
  • Partner with cross-functional teams to resolve tradeoffs, supplier nonconformances, and production issues.
  • Support field deployments and production startups, ensuring proper documentation and procedures are in place.
  • Act as the escalation owner for mechanical issues impacting fleet operations.

Requirements

  • 4+ years of industry experience designing electromechanical and structural assemblies.
  • Demonstrable ownership of complex subassemblies through full product cycles.
  • Deep CAD fluency, rigorous GD&T skills, and experience producing manufacturing-ready drawings and inspection criteria.
  • Proven track record applying FEA, hand calculations, tolerance analysis, and test correlation.
  • Hands-on prototyping and test experience, including building fixtures and closing design loops from test data.
  • Direct supplier engagement experience, including negotiating DFM changes and resolving quality issues.
  • Experience with structural components, mechanisms, fastener systems, composites or metallic airframe-scale assemblies, and designing for field serviceability.
  • Willingness and ability to travel to suppliers, production sites, and field depots.
  • Strong bias for taking end-to-end ownership until verified fixes are in production and fielded.
