Lead Manufacturing Engineer

About Us

Polar Dive USA is a cold‑plunge startup in Miami building high‑performance, compact water chillers. We have a working prototype, a product line already selling, and a market that's growing fast. Now we’re building our first production facility in the Hialeah/Medley area to take this from small‑batch to scaled manufacturing.

• Reverse‑Engineer & Document
  — Tear down our current prototype, build out the Bill of Materials, source components (compressors, heat exchangers, refrigerant circuits), and finalize the design for manufacturability.
• Build the Factory
  — Select and install production equipment including R290 charging stations, vacuum pumps, and ultrasonic sealers. You own the shop floor layout from day one.
• Safety & Compliance
  — Serve as our internal expert on R290 (propane) refrigerant safety. Manage EPA 608 compliance, UL certification (UL 60335‑2‑89), and local permitting including Miami‑Dade Fire Marshal approvals.
• Run Production
  — In the early days, you are the assembly line. As we scale, you’ll hire, train, and manage a team of 3–5 technicians to hit weekly production targets.

• You’re a mechanical engineer (BSME or equivalent hands‑on experience) with 5+ years in manufacturing, ideally in HVAC, refrigeration, or chiller systems. You understand the vapor compression cycle, you know why superheat and subcooling matter, and you’ve spent real time on a production floor — not just in a cubicle.
• R290 or hydrocarbon refrigerant experience is a strong plus. If you haven’t worked with flammable refrigerants yet but have a solid HVAC/refrigeration foundation and want to learn, we’re open to that.
• You’re the kind of engineer who can model a part in Solid Works in the morning, then put on gloves to braze a copper line in the afternoon. You’re comfortable being scrappy early so you can build something real.
• Bilingual English/Spanish is highly preferred given our Miami workforce.

CAD (Solid Works or Fusion 360), R290 charging equipment, brazing and soldering (nitrogen purge), electrical testing and run‑test stations.

• Salary: $90,000 – $120,000 depending on experience
• Equity: Stock options — you’re joining as a core member of the founding team
• Location: On‑site in Miami (Hialeah/Medley area)
• Growth: You’re building a manufacturing division from scratch with a clear path to Director of Operations as we scale
