Senior Frontend Engineer

Frontend Engineering at Phase goes well beyond “typical frontend work” (i.e. implementing a fairly standard interface in common frameworks). In Phase, the front end is much more involved and much more challenging.

We’re building large, custom codebases with high-performance client-side data manipulation. How do we compute the result of multiple, high-performance, runtime-computed interactions? That’s the front end at Phase. How does our editor let users create a reflowing and responsive layout in their design? That’s the front end at Phase. And much more…

This is a role for the frontend engineer who isn’t afraid of tough challenges.
