Senior Software Engineer, Front-End Focus
About The Position
Kin is looking for a Senior Software Engineer with deep front-end expertise to own and scale key areas of our in-house web applications. In this role, you’ll build modern, high-performance user experiences using Angular and Web Components (Lit), contribute to architectural decisions, and mentor other engineers. This is a high-ownership role for someone who thrives in a fast-paced, collaborative environment and wants to shape systemic solutions that directly impact homeowners. We’re looking for a Senior Software Engineer that’ll be focused on our front-end tech stack to help us scale and evolve the web applications that power Kin’s customer and internal experiences. As we expand our products and enter new markets, our in-house systems must remain fast, resilient, and intuitive. This role exists to ensure we build front-end systems that are not only functional but thoughtfully architected for long-term growth. You’ll work on a small, highly collaborative team, independently owning and operating complex features across our Angular and Web Component-based applications. At this level, you won’t just ship code — you’ll influence architecture, surface systemic improvements, and help elevate engineering standards across the team.
