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. The backend engineer builds the API, you make the product experience excellent before it reaches a customer - Participate in customer calls and read session recordings to understand real user scenarios, not just ticket descriptions - Enforce a quality bar on UX before features go live -- if the flow doesn't make sense to a recruiter, it doesn't ship What we're looking for - 2-4 years of professional software engineering experience - Strong CS fundamentals -- OOP principles, clean architecture, component design patterns. We will test for this - Deep experience with React, Next.js, and TypeScript in production - Comfortable with Tailwind CSS, Radix UI
