    We’re looking for a Full-Stack Developer with a backend focus to strengthen our team on a high-load payment gateway aggregator used across several markets in Asia and LATAM. The platform processes thousands of transactions daily and integrates with local payment providers in each region β€” acting as a key part of the company’s financial operations.

    You’ll work mostly on the backend: improving reliability, integrating with new providers, and making sure everything scales smoothly. Some occasional frontend work (React) may pop up too.

     

    How You’ll Contribute

    • Develop and scale backend services for payment processing and provider integrations
    • Work with local APIs and protocols across different markets (e.g., Thailand, Brazil, Philippines)
    • Optimize database performance and handle transactional flows reliably
    • Contribute to system stability and fault tolerance under increasing load
    • Occasionally assist with frontend tasks (React) β€” e.g., dashboards, transaction monitoring
    • Collaborate with a small full-stack team and participate in technical decision-making

     

    What Makes You a Perfect Fit

    • 2+ years of experience with Node.js/NestJS and PostgreSQL
    • Solid understanding of backend architecture, transactional flows, and API integrations
    • Experience working on high-load systems or products with real-time data
    • Strong TypeScript skills and a clean coding style
    • Familiarity with microservices, Docker, and CI/CD pipelines
    • Comfortable switching context when needed and supporting frontend if required (React)

     

    Nice-to-Haves

    • Experience integrating with payment systems or financial APIs
    • Understanding of fallback mechanisms and system reliability patterns
    • Interest in infrastructure monitoring and performance optimization
    • Experience working with region-specific products or international setups

     

    Our Tech Stack

    NestJS, Node.js, TypeScript, PostgreSQL, React, microservices, Docker, AWS, CI/CD pipelines, high-load architecture and provider APIs.

     

    Hiring Process

    The hiring process is clear and concise. It starts with a 30–40 min intro call with a Talent Partner β€” an opportunity to learn more about the project, Umber, and the team, as well as to discuss the candidate’s experience.

    Next comes a technical interview (~1.5 hours) covering both React and Node.js.

    The final step is a ~30 min conversation focused on managerial topics and organizational details.

     

    Your next challenge is waiting. Let’s connect, talk about the impact we can make, and see if we’re the right fit for each other!

     

     

    Who We Are

    Umber is a full-cycle product agency founded in 2018. We started as a design-driven company and now build complex finance systems from the ground up. Our current focus: payment solutions, trading platforms, and tools for professional investors and traders.

     

    We’re a small, ambitious, senior-level team working with top-tier financial clients. We’re passionate about finance, trading, and creating systems that don’t just work β€” they scale and shine under pressure. Check us out at https://umber.tech.

     

    Why Join Us
