Senior Software Engineer

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 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 Backend: Ruby on Rails 8.1 Frontend: React 18.3 (with some Stimulus / Turbo) Infrastructure: Heroku CI/CD: GitHub Actions Architecture: Modular monolith, engineers work across the stack What "Senior" Means at HireArt Own projects end‑to‑end Coordinate with teammates contributing to the same epic Make tradeoffs without perfect information Improve 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, senators proactively improve how work gets done. Compared to a staff engineer, seniors do less explicit culture reinforcement and organizational shaping. On‑call and Production Ownership On‑call is very limited A dedicated on‑call engineer escalates to the feature team ~10% of the time Expected involvement in debugging production issues is low Expectations around testing and code quality are high Requirements Significant, real‑world Ruby on Rails experience Experience owning large features end‑to‑end in a product organization Strong practice of writing and maintaining automated tests Comfortable working closely with product managers and stakeholders Proven ability to work with remote teams while staying highly communicative and proactive 8–10 years of professional experience, or equivalent depth through impact Nice‑to‑Have Experience Leading work involving Stimulus / Turbo Experience in entrepreneurial or early‑stage environments Strong end‑to‑end (E2E) testing practices ERP‑style data modeling or complex domain modeling Staffing, HR, or marketplace domain experience Interview Process Read and discuss a small Rails application Walk through a past project in depth and defend (or critique) technical decisions Be evaluated on clarity, humility, and impact—not just technical correctness Benefits Equity Dental, medical, and vision for yourself and your dependents Life and disability insurance Work‑from‑home stipends, including: Workspace/home office set‑up Company supplied Apple laptop Phone/internet stipend Uncapped PTO as well as paid office holidays 401(K) through Fidelity This is a full‑time, permanent position with HireArt and is open to candidates who reside and are authorized to work in the United States and able to work during Eastern Time Zone business hours. Unfortunately, we’re unable to offer sponsorships or do corp‑to‑corp. HireArt values diversity and is an Equal Opportunity Employer, which is why we are interested in every qualified candidate, regardless of their background, how they identify, or their inclusion in any protected class. Company description HireArt’s mission is to make it easy for companies to build and manage a world‑class contract workforce. Today, mid‑sized companies with contract workforces must navigate significant legal, financial, talent acquisition, and operational complexities to build and manage these workforces on a global scale. In most cases, they rely on a stack of point solutions: agencies to source and employ talent, a software system to track workers and agencies (VMS), and a service to provide day‑to‑day management of the program (MSP). The default contract workforce stack doesn’t provide much visibility into or control over the workforce, because the pieces of the stack don’t integrate well together, resulting in massive administrative headaches and frustration for companies. HireArt’s delightful intersection of humans and software provide all of the tooling needed for mid‑sized companies to hire contractors anywhere in the world compliantly, and contract workers to have as great an experience as full‑time employees have day‑to‑day. #J-18808-Ljbffr
