About The Position

As a Product Engineer, you’ll be one of the engineers closest to our customers, shaping how residents interact with local government every day. Your work will directly influence customer experience, retention, and adoption, while setting the quality bar for how government technology should feel. You’ll work across the stack to design and ship features that make government services intuitive, reliable, and even delightful. This role is full-stack at its core, but with an eye for detail on the customer-facing side of the product (React/Next.js). You’ll collaborate closely with product, design, and even directly with customers to understand needs, scope solutions, and deliver polished quality user experiences. Attention to detail, customer empathy, and ownership are key - you’ll be the type of engineer who makes sure the end result feels right to both the user and the system.

Strong experience in React/Next.js (frontend) and Node.js/TypeScript/Postgres (backend).

A customer-obsessed mindset, you care about user experience and details that make software enjoyable to use.

Self-awareness and a growth mindset - you seek feedback, take initiative, and continuously improve.

Nice To Haves

Experience working in early-stage startups, shipping 0→1 features.

Responsibilities

Own, build, and ship customer-facing features end-to-end.
