Greenhouse has partnered with Deel to be its Employer of Record in Argentina (more information here).  Through this arrangement, Deel is hiring a Senior Full Stack Software Engineer to provide services to Greenhouse.

This role will support the design, development, and evolution of the Company’s web-based applications. In this role, you will work across the entire application stack to deliver high-quality features for the Company. 

Your work will range from building net-new functionality to improving how data flows across the Company’s services at scale. This is a collaborative role where you will work closely with product, design, and engineering partners to ensure the platform remains performant, reliable, and user-friendly.

Who will love this job

  • A Pragmatic Architect - You don’t just write code, you think about how systems connect. You enjoy refining data models and improving system architecture to support long-term scalability.
  • A Full-Stack Specialist - You are equally comfortable navigating a PostgreSQL query, styling a React component, or building a robust controller in Rails.
  • A Quality Advocate - You believe “done” includes comprehensive automated tests and clear documentation. You take pride in leaving the codebase better than you found it.
  • A Collaborative Problem-Solver - You thrive in an environment where code reviews are a dialogue and cross-functional collaboration is the norm.
  • An AI fluent engineer – you already use tools like Claude to move faster, and you're excited to build on that experience

What you’ll do

  • Build, modify, and maintain features using Ruby on Rails, modern JavaScript frameworks (React), HTML, and CSS
  • Execute on high-impact projects
  • Ensure code is maintainable and aligned with established engineering standards
  • Contribute to the evolution of system architecture, including improvements to data transfer across services and ingestion pathways
  • Design and maintain RESTful APIs, webhook-driven integrations, and data exchange pathways with third-party systems
  • Diagnose and resolve complex integration issues to improve information flow
  • Design and update PostgreSQL data models, refactoring legacy models to improve performance and reduce complexity
  • Participate in production support during working hours, addressing bugs and escalations as needed
  • Use monitoring and observability tools to maintain application stability and support performance tuning
  • Participate in peer code reviews and provide constructive feedback
  • Produce technical documentation, including architecture notes, implementation guides, and runbooks
  • Write automated tests (unit, integration, and E2E) to ensure reliability and coverage

You should have

  • 5+ years of experience writing and maintaining production-level code in a professional environment
  • Strong experience with Ruby and Ruby on Rails
  • Experience with JavaScript and React, plus solid HTML and CSS fundamentals
  • Deep understanding of MVC architecture and backend optimization
  • Proven ability to write efficient SQL, design relational data models, and optimize PostgreSQL performance
  • Experience building and consuming RESTful APIs and managing third-party integrations via webhooks
  • Proficiency with automated testing frameworks (e.g., RSpec, Jest, Cypress) and a commitment to test-driven practices
  • Ability to contribute to architectural discussions and implement solutions that operate effectively at scale
  • Comfort working in agile environments using standard development tools such as Git, CI/CD pipelines, and observability platforms
  • Fluency in agentic coding and with leveraging and configuring AI tooling
