Umber

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. 

🌏 Your location must be in the Asia time zone.

The platform processes thousands of transactions daily and integrates with local payment providers in each region — 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) — 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 — 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.
