Job Description

The isolved Senior Software Engineer designs, builds, and owns complex functionality on the Perform product, working in an AI-first development environment. You'll use AI-assisted tools like Claude Code as a core part of your daily workflow, and you'll be expected to bring strong judgment about what that output gets right, what it gets wrong, and when it shouldn't be used at all.

Our teams work in an AI Development Lifecycle (AIDLC) where product, UX, engineering, and QA work through problems together in real time rather than handing off requirements down a line. As a Senior Engineer, you're an active voice in that room: shaping solutions, raising technical risks early, and helping turn ambiguous ideas into working software. You'll also be a go-to resource and mentor for other engineers on the team.
