Job Overview by Ladders

Qualifications

  • BS in Mechanical Engineering or related field; equivalent experience accepted
  • 10+ years of mechanical design experience in aerospace or high-rigor environments
  • Expert proficiency in PTC Creo, particularly in large assemblies
  • Strong understanding of Windchill workflows and configuration control
  • Proficient in GD&T per ASME Y14.5 for inspectable drawings
  • Experience designing for manufacturability in common aerospace processes
  • Strong ownership mentality from design to test phase.

Responsibilities

  • Own detailed mechanical CAD for spacecraft structures and features
  • Build and manage large top-level Creo assemblies with configuration discipline
  • Drive execution of spacecraft packaging with a focus on optimization and access
  • Create and release flight drawings with GD&T and inspection requirements
  • Ensure BOM accuracy and part metadata integrity in Windchill
  • Collaborate with AIT for buildable and testable designs
  • Support on-site spacecraft integration and rapid problem-solving
  • Provide design leadership and establish CAD best practices.

Benefits

  • Ownership of design authority on flight builds
  • Direct impact of CAD decisions on spacecraft missions
  • Opportunities for growth in setting design execution standards
  • Competitive compensation package with comprehensive benefits.
Full Job Description
This is a high-impact, hands-on design leadership role for someone who can take ambiguous spacecraft packaging constraints and translate them into clean, producible, testable hardware-then shepherd that design through release, build, integration, and test. You will partner daily with mechanical/structures/thermal engineers, AIT, manufacturing, supply chain, and systems to deliver flight-ready mechanical assemblies for Ranger spacecraft.

Where You'll Make an Impact
  • Own detailed mechanical CAD for spacecraft structures, mechanisms, secondary structure, brackets, harness routing accommodations, and payload mounting features
  • Build and maintain large top-level Creo assemblies with strong configuration discipline: envelopes, mass properties, interference control, motion/clearance checks, access constraints, and fastener strategy
  • Drive spacecraft packaging execution: volume optimization, keep-outs, service loops, access for torque/inspection, tool clearance, contamination control considerations, and integration sequence-friendly design
  • Create, check, and release flight drawings (and drawing packages) with correct GD&T, material callouts, finishes, treatments, and inspection requirements (ASME Y14.5 mindset)
  • Own BOM accuracy and part metadata integrity in Windchill (part lifecycle, revisioning, effectivity, serialization strategy where applicable)
  • Partner with AIT to ensure designs are buildable and testable: torque access, alignment features, witness marks, datum strategy, handling points, lifting features, GSE interfaces
  • Support on-site spacecraft integration: fit checks, rework disposition support, redlines-to-release, and fast iteration during build anomalies
  • Provide design leadership and mentorship: define "good" CAD practices, model tree hygiene, drawing standards, and release readiness checklists
  • Produce design content for PDR/CDR/production readiness reviews, including configuration views, interface snapshots, tolerance stack summaries, and assembly sequences


What It Takes
  • BS in Mechanical Engineering or related field (or equivalent demonstrable work products in spacecraft/aerospace design)
  • 10+ years of professional mechanical design experience in aerospace/spacecraft or similarly high-rigor hardware environments
  • Expert proficiency in PTC Creo (top-down design, skeletons, family tables, interface control via publish geometry, large-assembly performance discipline)
  • Strong working knowledge of Windchill release workflows and configuration control best practices
  • Deep experience applying GD&T per ASME Y14.5 and translating intent into inspectable drawings
  • Proven ability to design for manufacturability across common aerospace processes (machining, sheet metal, additive where appropriate, bonding, inserts/Heli-Coils, surface finishes)
  • High ownership: you don't just "model parts"-you drive closure through release, build, and test
  • Work location within the Washington DC / Maryland / Virginia (DMV) area


Nice-to-Have Experience
  • Spacecraft or launch vehicle flight hardware design experience
  • Direct experience supporting AIT on the floor (MRB disposition support, as-built capture, redline control)
  • Familiarity with contamination control, torque practices, workmanship standards, and aerospace fastener conventions
  • Experience with mechanism packaging and clearance validation


What You'll Get
  • Ownership - Be the design authority driving configuration quality on flight builds
  • Impact - Your CAD decisions will ship to orbit
  • Growth - Lead design execution standards across spacecraft programs
  • Compensation - Competitive salary, equity, and comprehensive benefits, including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity participation.
