Director of Engineering

at Nox Metals — Manufacturing
Location
Los Angeles, California
Salary
$200,000 - $350,000
Type
Full-Time
TL;DR
  • Applied frontier tech at scale at a winning company
  • Hands-on leader: architecture ↔ code ↔ people
  • Archetype: ex-SpaceX, Rainmaker, Anduril, late-20s senior SWE
  • Avoid: failed-startup CTOs
About Nox Metals
Nox Metals is an AI-powered metals supplier powering modern American manufacturing — building vertically integrated, automated factories that turn raw metal into production-ready material faster, cheaper, and more reliably than legacy service centers (“the factory is the product”). With operations in Metro Detroit and Los Angeles, it supplies aluminum plate, bar, and rounds to aerospace and defense manufacturers, using software and automation to move metal to American factories faster than the industry thought possible. Founded by CEO Zane Hengsperger (YC S25), Nox went $0→$14M revenue in its first year, and the company runs on its own internal software stack — NOX NEST, WAYNE, and Gondor — the products that run the business. It’s live with aluminum plate and block today, expanding into steel, tube, and sheet next, and is standing up a second factory in LA. After a $11.5M seed (Hyperion, Palmer Luckey, YC), Nox just raised a $45M Series A from a tier-one investor (unannounced) at ~$500M valuation, is quoting serious volume (a ~$7M/month long-term agreement with SpaceX in progress).

About This Role

Nox is hiring a Director of Engineering to build the software organization and systems that run the company — owning technical direction, engineering execution, and team development across customer software, internal operations, data, infrastructure, and applied ML. It’s explicitly a hands-on leadership role: you make architecture and hiring decisions but stay close to the code, the factory floor, and the people using what you build. The goal isn’t software for its own sake — it’s a faster, more reliable American metals supply chain.

The bar Jack set in the intake is specific: less about deep manufacturing experience, more about having applied frontier technology at scale at a company that won — someone who’s shipped something genuinely compelling (AI or another breakthrough) inside a winning org, not a founding-CTO-of-a-mediocre-startup. He wants someone hungry and on the rise, not too old, who other engineers gravitate toward (ideally with a built-in network, since you’ll recruit alongside the founders constantly). Profile is flexible: a high-performing senior SWE (mid-to-late 20s) on a clear leadership path comes in as Director; someone who’s been a director-by-scope also works — if forced to pick, Jack leans Director. The scaling thought-partnership (1→n) is what the founders most need; they’re strong at 0→1 themselves.

You Will

  • Set the technical strategy and engineering roadmap for the company
  • Recruit, develop, and lead a high-performing engineering team
  • Establish durable architecture across customer, commercial, and manufacturing systems
  • Stay close enough to the code to review critical designs and unblock difficult work
  • Turn company priorities into clear technical plans, owners, and delivery dates
  • Raise the standard for reliability, security, testing, observability, documentation
  • Work directly with sales, ops, finance, and manufacturing to understand real workflows
  • Build an engineering culture of speed, judgment, ownership, and direct user contact
  • Make thoughtful build-vs-buy decisions and manage technical risk; measure whether engineering improves customer experience and factory performance

You Are

  • A strong technical leader who moves fluidly between architecture, execution, and people management — still technically sharp, willing to get into details
  • Experienced shipping and operating business-critical software
  • Applied frontier tech (AI or another breakthrough) at scale, at a company that won (the core bar)
  • Clear on priorities; decides with incomplete information
  • A direct, thoughtful communicator who raises the performance of people around them
  • Comfortable with both engineers and factory operators
  • Motivated by measurable business/operational outcomes; low ego, high ownership, steady under pressure
  • Hungry, on the rise, not too old; a magnet for other engineers (built-in network a big plus)

Nice to Have

  • Manufacturing, logistics, supply chain, or industrial software
  • Optimization, data products, or production ML
  • Scaling an engineering team in a fast-growing company
  • Comfort using AI tools to improve engineering speed/quality

Background Nox values / screens on

  • Winning-organization DNA — having been part of an org that does things incredibly well (he screens out “founding CTO of a startup that kind of sucked”)
  • College pedigree matters to him (even in late 20s — a proxy for consistent, long-run excellence; he named Georgia Tech and Harvey Mudd as favorites) — though ultimately “winning org + demonstrated technical trials” is the real bar
  • Archetype examples he cited: ex-SpaceX engineers (esp. mechanical-to-software transitions), Rainmaker-type “applied frontier tech at scale” profiles

Who Will Thrive Here

  • A hands-on eng leader who’s applied frontier tech at scale at a winning company and wants to build an org from the ground up
  • A hungry, on-the-rise technologist other engineers follow, with a network to recruit from
  • Someone energized by measurable factory/customer outcomes and comfortable on the floor
  • Low-ego, high-ownership, direct, steady under pressure
  • The 1→n scaling thought-partner the 0→1 founders need
