HireArt Senior Software Engineer HireArt Full time Location New York, NY, United States (Remote) Work environment Remote Expected pay amount 175,000.00 - 200,000.00 USD Per Year Schedule Monday - Friday (ET) Assignment length Permanent Job description HireArt is a modern staffing platform for companies to source, employ, and manage contract workers. Our goal is to bring a turnkey, full-stack software and service experience to an industry that is dominated by manual, cumbersome processes. We're a ~75-person company with an experienced engineering team and a product that serves real customers every day. Our typical customers are fast growing tech companies, such as those building autonomous vehicles and LLMs. We're hiring a Senior Software Engineer to join our Feature Team as we scale delivery capacity across our core platform. This role is for an experienced senior engineer; someone who can learn business context, collaborate with the product team, own a feature end-to-end, and raise the effectiveness of their team. About the Role You'll work on HireArt's core staffing application - a large, modular Rails codebase with real production constraints. Work typically arrives as loosely defined problem statements. Senior engineers help bring context to those problems, shape solutions, clarify tradeoffs, and deliver changes that are easy for the next engineer to build on. You'll sometimes lead initiatives, sometimes follow another senior engineer's direction, and always be expected to communicate clearly, push back thoughtfully, and keep delivery moving. What You'll Do Own large product features end-to-end, from shaping the approach through delivery Break down ambiguous problems into clear technical changes Work closely with product partners to clarify requirements and push back on scope Communicate clearly and often with teammates and manager regarding expectations for delivery Review code with an eye toward maintainability, not just correctness Write and maintain automated tests as a first-class responsibility Improve legacy areas of the codebase incrementally and pragmatically Use AI tools (Copilot, Claude, etc.) to increase throughput while remaining fully accountable for the code you ship Our Tech Stack
