About the Job

The company is hiring a Senior Frontend Engineer to help build polished, high-performing web experiences for ambitious eCommerce and SaaS clients. You will turn thoughtful designs and product direction into production-ready interfaces, bringing the care, judgment, and craft that make digital products reliable and easy to love.

• Experience translating Figma designs into accurate, responsive, accessible interfaces.

• Experience integrating REST or GraphQL APIs and managing client and server state.

• A strong quality discipline: typed, tested code and self-review before QA.

• Ability to estimate your work, commit within a delivery cycle, and reliably deliver.

• Experience working in a points-based or sprint-based delivery model.

• A portfolio, GitHub, or code samples you can share.
