The Opportunity

In this role, you will be working on a global scale, contributing to the development of brand-new, high-impact systems designed to support our evolving business needs.

We are looking for a skilled and passionate Full Stack Developer who leans backend with strong experience in Node.js and Java (or other backend languages) to join our engineering organization. In this role, you’ll design, develop, and maintain highly scalable, reliable, and secure systems end-to-end. You will work closely with product managers, designers, and fellow engineers to deliver impactful solutions that serve real user needs across our global portfolio.

What you'll do:
• Design and develop high-performance, fault-tolerant backend systems and user-facing features using Node.js and Java (or other backend languages).

• Collaborate with Product, Design, and Engineering teams to define, develop, and deliver complex features.

• Take end-to-end ownership of services and components from design to deployment and operations.

• Build and maintain secure, scalable, and maintainable RESTful or GraphQL APIs.

• Participate in code reviews, architecture discussions, and promote best engineering practices.

• Identify areas for performance and reliability improvements and proactively address them.

• Work in an agile team, contributing to sprints, stand-ups, retrospectives, and planning sessions.

• Stay up to date with emerging technologies and share knowledge with the team.

What you'll bring :
•
At least 5+ years of experience in software development.

•
A bachelor’s degree in computer science, engineering, mathematics, or a related field (or equivalent experience).

•
Strong proficiency in Node.js / TypeScript, ideally with a modern backend framework (NestJS, Express, Fastify, or similar). (Required).

•
Expertise in Java or another backend programming language (such as Scala, Kotlin, Go, C/C++, Rust, Python, etc.) and the ability to learn new languages quickly.

•
Solid TypeScript and React skills enough to implement and maintain features in a Next.js codebase alongside backend changes (you don't need to be a dedicated UI engineer).

•
Strong understanding of backend architecture and data systems: relational databases, NoSQL, caches, queues / messaging, and REST or GraphQL API design.

•
A bias toward automation: automated testing, CI/CD pipelines, and infrastructure-as-code as defaults rather than afterthoughts.

•
Comfort working in an agile team (Scrum, Kanban, or similar) and collaborating effectively with Product, Design, and other engineers.

•
Good command of the English language and the ability to communicate effectively.

We are proud to be an equal opportunity employer, embracing the unique qualities of every individual, regardless of gender, race, age, religion, disability, or other local protected classes. Our goal is to foster an inclusive environment where everyone feels welcome and valued.
