You will build end-to-end product capabilities, from user-facing workflows to the systems that support them. You are comfortable working across the stack and can independently own substantial areas of functionality.

You contribute to system design, raise risks and edge cases early, and deliver solutions that are reliable, maintainable, and production-ready. You partner closely with the Lead Engineer, Product, and Design to translate product direction into cohesive, well-executed technical work.

• Raise risks, edge cases, and tradeoffs early.
• Write high-quality, well-tested code and actively participate in code reviews.
• Improve reliability, performance, and maintainability of the systems you touch.
• Monitor system health and help diagnose and resolve production issues.
• Collaborate with other teams when integrations or shared systems are involved.
• Participate in root cause analysis and strengthen systems to prevent recurring issues.

What We’re Looking For

• 5–8+ years of professional software engineering experience.
• Strong full-stack capability and experience building end-to-end product features.
• Experience designing and delivering production systems used by real customers.
• Solid system design fundamentals and the ability to translate product requirements into clean technical solutions.
• Experience working effectively within an existing codebase and improving it over time.
• Comfort operating in a small team with high ownership and shared responsibility.
• Experience working in cloud-hosted environments (e.g., AWS) with CI/CD and automated testing.
• Experience with workflow automation or AI-enabled features.
• Clear communicator who can explain technical decisions and collaborate effectively across disciplines.

Nice to Have

• Experience with Ruby on Rails.
• Experience building workflow-heavy or data-intensive applications.
• Experience working in SaaS or revenue-generating environments.
• Experience mentoring junior engineers or leading small technical efforts.
