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

• Backend: Ruby on Rails 8.1
• Frontend: React 18.3 (with some Stimulus / Turbo)
• Datastores: PostgreSQL, Redis
• Infrastructure: Heroku
• CI/CD: GitHub Actions
• Architecture: Modular monolith, engineers work across the stack

What "Senior" Means at HireArt

A senior engineer here is trusted to:

• 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, seniors 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
• 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

Candidates can expect to:

• Read and discuss a small Rails application
• Identify impactful improvement opportunities
• Walk through a past project in depth and defend (or critique) technical decisions
• Be evaluated on clarity, humility, and impact—not just technical correctness
