Intermediate Developer, Fullscript

• If you enjoy untangling complex problems, designing systems that scale, and building integrations that make the business run smoother, you’ll feel right at home
• The team values clear thinking, strong communication, and high ownership. We care about doing things well and helping each other grow along the way
• 5+ years of experience building applications and integrations in frameworks like Ruby on Rails, Python, or Typescript (or other OOP languages)
• Strong software engineering fundamentals and a track record of building reliable backend systems
• Experience with business operations or commerce ecosystems such as e-commerce checkouts, ERPs, OMS, WMS, or accounting systems
• Comfort designing and delivering integration services, data models, and SQL-based solutions
• A thoughtful approach to testing (knowing what should be automated, what shouldn’t, and how to collaborate with business users on acceptance testing)
• Ability to communicate clearly with both technical and non-technical stakeholders and turn business requirements into technical designs
• A mindset oriented around ownership, clarity, and long-term thinking
• A habit of thinking in systems — how data flows, where it breaks, and how to make it more resilient
