The posting

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-Have

  • 5+ 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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
