Senior Software Engineer - Full Stack

Senior Software Engineer - Full Stack // Colombo HeyMilo helps recruiters deploy multimodal AI agents that interview and evaluate candidates at scale. We're a fast-moving team backed by prominent investors growing at an unprecedented rate. You'll own the recruiter-facing admin platform and the candidate interview experience end-to-end. This means shipping features, refactoring legacy flows, killing dead code, and making sure every screen a recruiter or candidate touches actually works well -- not just functionally, but experientially. You'll work closely with our UX and backend leads to make sure nothing ships half-baked. This is not a ticket queue. You'll be embedded in customer conversations, understand what recruiters actually need, and turn that into clean, well-architected product. Requires flexibility to work evenings (IST) for overlap with our New York/Toronto teams. What you'll do Own the admin dashboard (agent creation, interview templates, email config, analytics) and the candidate-facing interview app (voice, video, SMS flows) Refactor and consolidate -- we have duplicate components, dead code, and flows that grew organically for individual customers. You'll architect reusable patterns and clean the codebase methodically, feature by feature, not micro-fix by micro-fix Ship full-stack features end-to-end.
