Backed by leading climate and American dynamism investors, Terranova builds intelligent robotic systems to terraform the Earth itself - lifting land, restoring wetlands, and protecting critical infrastructure from floods and sea-level rise. Comfortable with the pace and intensity of early-stage startup life, including long days, 6-day workweeks, and extended field hours.

Terranova

Mechanical Engineer

You will take products from early concept through high-volume manufacturing, working closely with Industrial Design (ID), Electrical/Hardware Engineering, NPI/Operations, and external suppliers/contract manufacturers to deliver production-ready designs. Plan and support prototype builds and validation (EVT/DVT/PVT or equivalent): define build objectives and acceptance criteria; evaluate fit/function, cosmetic, key dimensions, and assembly robustness; drive issue closure through subsequent builds.

TP-Link Corp

Deep familiarity with modern manufacturing processes and when to apply each: CNC machining (3- and 5-axis), injection molding, die casting, sheet metal fabrication, MIM (metal injection molding), investment casting, and surface finishing processes (anodizing, PVD, powder coat); understanding of process tradeoffs across cost, tolerance, lead time, and volume. Demonstrated ability to take a mechanical design from working prototype to production-ready — including DFM iterations, supplier qualification, first-article inspection, and manufacturing yield validation; candidates who have only operated in R&D or prototype-only environments are not a fit for this role.
