Senior Software Engineer

Expected compensation: 175,000.00 - 200,000.00 USD Per Year 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 deliveryBreak down ambiguous problems into clear technical changesWork closely with product partners to clarify requirements and push back on scopeCommunicate clearly and often with teammates and manager regarding expectations for deliveryReview code with an eye toward maintainability, not just correctnessWrite and maintain automated tests as a first-class responsibilityImprove legacy areas of the codebase incrementally and pragmaticallyUse AI tools (Copilot, Claude, etc.) to increase throughput while remaining fully accountable for the code you ship Our Tech Stack Backend: Ruby on Rails 8.1Frontend: React 18.3 (with some Stimulus / Turbo)Datastores: PostgreSQL, RedisInfrastructure: HerokuCI/CD: GitHub ActionsArchitecture: Modular monolith, engineers work across the stack What "Senior" Means at HireArt A Senior Engineer Here Is Trusted To Own projects end-to-endCoordinate with teammates contributing to the same epicMake tradeoffs without perfect informationImprove team velocity, not just personal output Senior engineers are not expected to operate on autopilot or wait to be told exactly what to do. Compared to a mid-level engineer, seniors proactively improve how work gets done. Compared to a staff engineer, seniors do less explicit culture reinforcement and organizational shaping.
