We’re hiring! Join GRAYL as our next Product Development Engineer
. We build industry‑leading water treatment products that empower adventure for our community. Your role will help bring novel water treatment devices to life, create cutting‑edge designs, and solve challenging engineering riddles. You’ll draw, CAD, prototype, test, learn and improve. We’re looking for a CAD wizard who is passionate about solving technical problems and delivering high‑quality products.

At GRAYL, we don't just build products; we engineer essential gear for life's most challenging expeditions. Our durable, best‑in‑market purifiers are crafted to withstand the harshest conditions, empowering self‑reliant adventure for those who dare to explore. Beyond innovation, we're driven by purpose: we proudly contribute 1% of annual sales revenue to non‑profit environmental organizations, and our team enjoys 2 paid volunteer days to support causes they believe in.

Hybrid position: 2‑3 days/week in our Seattle office. 4‑6 weeks per year of travel, including travel abroad, nights in tents, and dirt under fingernails.

The Product Development Engineer works with a small, talented crew to bring products from proof‑of‑concept to on‑the‑shelf goods. You research materials, technologies, and market potential, use DFM‑influenced CAD to design, build and test prototypes, and collaborate with design and manufacturing teams to bring products to life. You communicate across the company to build support and receive feedback.

You are fueled by a passion for solving water problems for adventurous customers. You have a proven track record of bringing innovative products from concept to market, thrive in a collaborative environment, and value team success. You are organized, adaptable, and a natural problem‑solver who embraces ambiguity and evolves approaches as new insights arise.

You have spent time in the wilds as a member of one or more of our target markets (camp, hunt, overland, MTB, climb/alpine, bushcraft, travel and military). You’ve been thirsty and needed to rely on unsafe water. You bring great energy, contribute positively outside your own projects, and have a roll‑up‑your‑sleeves attitude.

• Share results with colleagues in a clear and energetic manner.
• Collaborate with product managers, developers, content strategists, user researchers, and other designers.
• Nurture GRAYL’s culture: work hard, play outdoors, love nature.
