Apply Now
About the position Join as a Backend Engineer and help rebuild payments for the >$1tn distribution industry. You’ll architect and build the systems that process millions of dollars in transactions daily, integrate with complex ERP systems, and leverage cutting-edge LLM technology to transform how distributors manage their revenue cycles. You’ll join a small team of A+ players where everyone acts as an individual contributor while actively supporting each other through pair programming and collaborative problem-solving. You’ll work closely with our founder-led team who previously operated a distribution business and understand the real-world problems we’re solving. Responsibilities • Architect and build systems that process millions of dollars in transactions daily. • Integrate with complex ERP systems. • Leverage LLM technology to transform how distributors manage their revenue cycles. • Own high-volume payment processing systems and secure financial APIs. • Own deep integrations with major ERPs (NetSuite, Sage, Acumatica, etc.). • Own LLM-powered workflows (credit decisions, remittance matching, automated comms). • Own real-time data pipelines handling millions of financial records. • Own AR / collections automation that directly impacts customer cash flow. Requirements • 4+ years of backend experience with strong system design chops. • Expert-level Ruby on Rails (Rails 7+, Ruby 3+). • Advanced PostgreSQL (query optimization, large datasets, logical replication, etc.). • Proven ability to design clean, versioned REST/JSON APIs. • Experience shipping and operating ETL/background-job heavy systems in production. • AI-Native: You already use Cursor, Claude, GitHub Copilot, or similar every single day. You treat AI as a pair programmer, not a toy or a threat. • Product-minded: You obsess over the “why” behind features, dig into customer data (or talk to customers), and measure success in revenue and user love — not story points. • Ownership > tasks: You hate being blocked. When something is unclear or broken, you prototype, reach out directly, pair, or just ship a pragmatic solution. • Builder mentality: Strong opinions, weakly held. You default to shipping the simplest thing that works (often with AI help), then iterate fast. Nice-to-haves • Built or maintained third-party integrations with enterprise software. • Real fintech, payments, or billing experience (Stripe, ACH, lockbox, etc.). • Hands-on LLM integration or prompt engineering (bonus if you’ve shipped it to production). Benefits • Flexible paid time off • Up to $100/mo wellness reimbursements • Competitive stock option grant • Medical, dental, and vision insurance, with 100% of premiums paid • Quarterly team gatherings for periodic in-person collaborative strategy and work sessions • A passionate, supportive team dedicated to learning and growing together.
