Job Overview by Ladders

Qualifications

  • 5+ years in motor design, electrical machines, power electronics, or traction drive engineering.
  • Fluency in winding design and insulation systems (magnet wire, enamel, impregnation, slot liner, phase paper).
  • Strong grasp of thermal and dielectric constraints in high-power motors.
  • Comfort with material, motor, and system interfaces; adept in polymer chemistry and bus voltage.
  • Ability to conduct technical reviews with customer engineers and secure next steps.
  • Experience with defense or aerospace motor programs, 800V+ systems, or high-speed motors (above 20,000 rpm) is a plus.
  • Bias toward shipping.

Responsibilities

  • Translate Vandrel wire's material properties into crucial motor performance metrics for customers.
  • Collaborate directly with design teams across various industries to integrate Vandrel wire into their systems.
  • Develop performance models to quantify benefits of Vandrel wire in specified motor topologies.
  • Lead design discussions regarding winding choices and insulation system compatibility with client teams.
  • Shape the initial product line based on practical customer needs and feedback.
  • Support customer qualification processes and collaborate with engineering on product durability and failure analysis.
  • Craft and communicate Vandrel's technical narrative to various stakeholders, representing the company at key forums.

Benefits

  • Opportunity for co-founder-level equity and title based on qualifications.
  • Work within a venture-backed environment in the hard tech sector for competitive compensation.
  • Engage in high-impact projects shaping the future of electrification and power systems.
Full Job Description
WHAT YOU'LL BE DOING
  • Bridge Material to System: Translate Vandrel wire's material properties (dielectric strength, temperature rating, thinner insulation, higher slot fill) into motor-level performance deltas customers care about: continuous torque, peak power, thermal headroom, bus voltage, eLiciency, partial discharge life.
  • Run Customer Engineering: Work directly with design teams at defense drone and autonomy primes, aerospace motor programs, EV OEMs, industrial drives, and gridscale power electronics to get Vandrel wire designed into their systems.
  • Build Performance Models: Quantify the gain Vandrel wire delivers in a given motor topology through thermal, electromagnetic, and dielectric modeling.
  • Drive Winding Design Conversations: Own the technical dialogue on slot fill, insulation system compatibility, and hairpin versus distributed winding tradeoLs with customer engineering teams.
  • Define Vandrel's First SKUs: Shape the initial product line based on real customer use cases: conductor size, insulation thickness, build class, and temperature class. Feed requirements into the process and materials roadmap.
  • Own Qualification and Test: Support customer qualification (HIPOT, partial discharge, thermal aging, fluid compatibility, thermal shock, vibration). Partner with process engineering to reproduce failures and harden the product.
  • Own the Technical Story: Build and present the narrative for why Vandrel wire wins at the chemistry, motor, and system levels. Represent Vandrel at customer reviews, technical conferences, and design-in sessions.


REQUIRED SKILLS
  • 5+ years in motor design, electrical machines, power electronics, or traction drive engineering.
  • Fluency in winding design and insulation systems (magnet wire, enamel, impregnation, slot liner, phase paper).
  • Strong grasp of thermal and dielectric constraints in high-power motors.
  • Comfort across the interface between material, motor, and system: you move easily between polymer chemistry and bus voltage.
  • Customer-facing chops: you can run a technical review with a customer's chief motor engineer and walk out with a next step.
  • Experience with defense or aerospace motor programs, 800V+ systems, or highspeed motors (above 20,000 rpm) is a plus.
  • Bias toward shipping.


COMPENSATION AND EQUITY

Compensation is benchmarked to senior motor and electrification talent at venture backed hard tech companies. Base salary is competitive and equity is material; both scale with experience and scope of ownership.

For candidates with deep motor and systems credibility and the appetite to own Vandrel's commercial-technical surface from day one, we are open to structuring this as a cofounder-level package: co-founder equity, commensurate title, and the authority that comes with it.
