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. Responsibilities Here's some of what we might expect of a new hire:

• Capable of taking the lead role in architecting own code, which fits correctly into the larger system architecture.

• Provide useful code review (consistent with our company’s standards) on other engineers’ Merge Requests.

• Proactive participation in group planning, meetings, and other discussions.

• Capable of communicating a detailed explanation of our product vision (broken into specific features).

• Complete a full BDD process (alongside designers, product, and QA) correctly completing the engineering role’s responsibilities in BDD.
