Software Engineer - The Digital Architect of Safety


The Mission: Save Brains


At KAV, you will use advanced manufacturing to save lives and insure our industrial sovereignty. Our goal is simple but massive: Save lives and reduce brain damage across every human endeavor. KAV is backed by 43North, Precursor Ventures, Brown & White and partners at Battery Ventures and Next Step Capital.


The Role: Coding the Future of Fabrication


You won’t be moving buttons around a screen or building another CRUD app. You will own the proprietary fabrication stack that powers our factory. From our impact testing platforms to our farm automation to our custom slicing engine, your code will be the bridge between a digital scan and a physical lifesaver.

What You’ll Be Doing


  • Orchestrate the Farm: Automate and streamline our 3D printer farm to scale the production of the most advanced helmets on Earth.
  • The Lifeblood (ERP): Integrate and evolve the ERP system that manages our entire end-to-end business logic.
  • Optimize the Slice: Enhance our proprietary slicing software to reduce scrap, improve tolerances and enable industry leading products.
  • One click head scans on any device: Use AI to extend our class leading, single photo, head rendering technology to any device.
  • The Lab-to-Life Loop: Work directly with our impact testing platform to turn crash data into better software requirements.


Key Ingredients for Success


  • Mission-Obsessed: You don’t just want a job; you want your work to matter. You bring a relentless drive to everything you build.
  • Self-Starting Polymath: We are an early-stage team. You need the initiative to look at our infrastructure, spot the bottlenecks, and translate product goals into elegant, unit-tested code.
  • Complexity is Your Playground: You thrive on novel problems at the intersection of bits and atoms.
  • Technical Chops: 3–5 years of software development experience, or the work ethic to make up the difference.


The KAV Experience


  • Bleeding Edge: Work at the literal frontier of advanced manufacturing, AI, and generative design.
  • Impact: Your code doesn't just live in the cloud; it creates a physical product that protects people in the real world.
  • Equity: Competitive salary and meaningful stock options in an early-stage startup poised to redefine an industry.

Apply (Important)

  • Send your resume and a few bullets outlining your interest and experience to whitman@kavsports.com
