Job description

Who We Are

Sans is on a mission to build the next great consumer hardware brand, with a laser focus on products that help people live healthier lives at home. We started with a category‑leading air purifier before expanding to a best‑in‑class countertop water purifier that actually works to eliminate harmful contaminants – and our product roadmap is just getting started.

We’re a small, ambitious team that believes deeply in our ability to create a meaningful consumer brand. We move fast, learn quickly, and consistently outperform much larger competitors.

Your Role

The Full Stack Engineer will build the software that powers both the customer experience and the internal systems behind Sans. This role spans our Shopify Hydrogen storefront, several Next.js applications, and a growing set of internal AI tools. This role will report to the Director of E‑Commerce & work closely with them on product direction and will also work directly with the CEO on technical priorities. The work is hands‑on, fast‑moving, and highly visible. You’ll spot a problem, build the fix, and see the impact quickly.

The ideal candidate is strong across the stack and already uses AI development tools as part of how they build. They should be excited by a wide range of problems, from storefront UX and conversion to data flows, AI features, and internal tools. They should be comfortable working without heavy process, able to move from idea to production quickly, and motivated by building things that make a small team much more effective.

Responsibilities and Duties

• Own and improve the Sans headless storefront built on Shopify Hydrogen and React Router, with a focus on conversion, performance, and a clean purchase experience
• Build the dedicated commerce experience that will support our upcoming mobile app and create a seamless connection between web and app
• Architect and ship customer‑facing AI features, including a conversational recommendation experience that helps customers find the right product for their home, use case, and environment
• Build systems that turn customer feedback into usable signal by pulling from support tickets, reviews, and social comments and making that information accessible across the company
• Develop internal tools and AI‑powered workflows that help teams move faster across operations, customer experience, and growth
• Maintain and expand integrations across our ecommerce stack, including Klaviyo, Attentive, Gorgias, and similar platforms, with clear ownership of APIs, webhooks, and data flows
• Partner with the Head of Digital, Creative, and CX teams to translate customer needs and business priorities into shipped software
• Contribute to technical strategy and help shape how Sans uses modern tooling, including AI‑assisted development, to build faster and operate more effectively
• This is an individual contributor role with broad ownership across customer‑facing products and internal software systems.
