About the role

Key responsibilities & impact

Dashboard — The dashboard is the command center that Ampersand customers go to to manage and troubleshoot their integrations. It serves engineers, product managers, and customer enablement teams. You will work on the dashboard experience, including how it looks, feels, and functions.
UI library — The Ampersand UI library is a set of embeddable React components and hooks that Ampersand customers put into their application for their customers to set up their integrations. Because it is a part of our customer’s product experiences and frontend stack, there are unique technical and UX challenges to ensure that it is composable, flexible and seamlessly fit into our user’s UI.
UI Prototyping — You have the freedom to come up with idea and rapidly prototype them using AI tools. You don’t need to wait for mocks or get buy in from a designer. You need to have great taste and intuition.
Customer Engagement — Talk directly to customers — user testing sessions, support questions, feedback gathering. Let what you hear shape what you build.
Full Stack Feature Development — Own the full loop: design, implementation, documentation, and customer communication. No throwing work over the fence. You are not afraid to dive into the backend and make PRs to unblock yourself.
Frontend Performance — Our dashboard is data-intensive, and you will work to ensure that the experience feels snappy and delightful.

Requirements

What you’ll need

4+ years engineering and designing digital products, ideally in B2B SaaS, developer tools, enterprise software, or technical products
Strong React skills with full-stack range (bonus if you have a genuine willingness to go deep in Go on the backend)
You are AI-forward and love trying new AI tools. You think of yourself not as a coder, but as a builder who harnesses AI to multiply their productivity.
Strong communication skills; you can articulate design decisions and push back when something isn't right. Engineers here write their own feature docs and own their decisions
Great taste in what makes developer tools intuitive; ideally you've shipped customer-facing developer products before
Strong product intuition — you can work directly with customers to design features, not just implement specs.
