    Staff Engineer @ Payflows – Build the AI-native ERP of tomorrow. Own what you ship, work on real-world challenges, and have a direct impact on how finance teams operate and scale.

    Job description

    🌍 Our Vision & Mission

    At Payflows, we give finance teams the tools to reclaim their time and energy. Our platform weaves together banking connectivity, payments, AI, and procurement so they can ditch the busywork and focus on what really moves the needle.

    🤝 Why Join Us?

    We’re a small, experienced team who’ve earned our stripes at Airbnb, Luko, BNP Paribas, and Facebook. It’s not always easy—things move fast, and we expect a lot—but if you’re hungry for impact, you’ll find it here.

    🛠️ We’re builders at heart. We move fast, think deeply, ship often — and we’re always on the hunt to learn more. You'll collaborate closely with product and tech to craft elegant backend systems that scale as fast as we do.

    🚀 What You’ll Do

    • Drive Architecture & Technical Strategy: Evolve our platform architecture & system design.

    • Own & Build: Take charge of entire domains, spec & write clean and scalable code.

    • Elevate Engineering Quality: Champion coding standards, eliminate systemic issues.

    • Enable High Performing Teams: Mentor engineers of all levels and multiply the impact of each team.

    • Optimize workflows: Spot performance bottlenecks, improve CI/CD pipelines, and push for smarter tooling.

    • Improve Reliability & Security: Identify and address critical technical debt, failure modes and security weaknesses.

    You will have the freedom to focus on the problems you identify, the autonomy to take a hands-on approach to solving them, and the accountability for your results.
