Responsibilities

Take full ownership of product areas: scoping, designing, building, and iterating on them

Build clean, fast, polished web interfaces with Next.js that feel almost native

Write simple, performant backend services in Bun/TypeScript

Deploy and manage infrastructure on AWS (EKS, S3, and the usual suspects) using Kubernetes

Obsess over the small things, from loading states, smooth animations, solid error handling to edge cases, the things that turn a good product into a great one

Make smart product tradeoffs with little hand-holding: know when to ship fast and when to spend extra time polishing

Help shape our product culture and engineering standards as one of the first engineers on the team

Qualification

Required

Proven experience shipping complete products, not just individual features (ideally something you can show us)

Serious frontend skills: you're very comfortable with React/Next.js, CSS, and modern web APIs

A sharp eye for design and motion: you notice when an animation eases awkwardly, when padding feels inconsistent, or when something just looks cheap

Solid backend chops: you can build APIs, work with databases, and troubleshoot production issues

Enough infrastructure comfort to handle AWS, containers, and Kubernetes (you don't need to be a DevOps wizard, but you're not scared of a Dockerfile either)

Ability to move independently in ambiguous situations

Real taste. You have strong opinions (and reasons) about what makes software feel good to use
