Member of Technical Staff - Full Stack Austin, TX | Remote (US) | Full-time About the Role Join Suppli 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. Who Thrives Here (read this first — it saves everyone time) 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.

What You’ll Own High-volume payment processing systems and secure financial APIs Deep integrations with major ERPs (NetSuite, Sage, Acumatica, etc.

) LLM-powered workflows (credit decisions, remittance matching, automated comms) Real-time data pipelines handling millions of financial records AR / collections automation that directly impacts customer cash flow Must-Have5+ years of backend experience with strong system design chops Expert-level Ruby on Rails (Rails 7+, Ruby 3+) — our core backend is modern Rails and you’ll own huge parts of it from day one → Exceptional candidates with deep experience in Django, Laravel, Spring Boot, or similar who are excited to go all-in on Rails will be considered 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 Bonus Points 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) Previously worked at a Series A–C startup and loved the chaos Tech Stack (today — evolves fast) Backend: Rails 7+, PostgreSQL, Sidekiq, Redis Infra: AWS, Docker, Terraform, CI/CD AI: OpenAI / Anthropic APIs, vector DBs, Cursor/Claude daily Security: Bank-grade encryption, SOC 2 in progress Engineering Culture True end-to-end ownership — no PMs writing pixel-perfect specs.

We pair program (human + AI), ship daily, write tests that matter, and refactor mercilessly. AI tools are first-class citizens here: we expect you to 10× your output with them and help us push the boundaries of what’s possible in fintech automation. Benefits 🌴 Flexible paid time off so you can recharge.

🏋️ Up to $100/mo wellness reimbursements. 🖥️ Up to $500/year home office stipend 📈 A competitive stock option grant, so you have skin in the game. ⚕️Medical, dental, and vision insurance, with 100% of premiums paid by us. 📍Quarterly team gatherings for periodic in-person collaborative strategy and work sessions.

👫 A passionate, supportive team dedicated to learning and growing together. Originally posted on Himalayas
