We're looking for a strong Java engineer — someone who writes clean, production-grade code, takes ownership of complex systems, and cares deeply about software craftsmanship.

What You'll Own

Java Development — Your Primary Focus

• Design, build, and own high-quality, production-grade Java applications with a strong emphasis on clean architecture, code correctness, and long-term maintainability.
• Write robust, well-tested backend code using Java and Spring Boot — this is the core of the role.
• Contribute meaningfully to code reviews, enforce engineering best practices, and raise the bar for the entire team.
• Architect and evolve our Integration Framework with a focus on flexibility, modularity, and reusability — your code will be relied upon by multiple teams and partners.

Cross-Functional Delivery

• Partner with Product and QA teams to translate requirements into reliable, shippable engineering solutions.
• Take end-to-end ownership of assigned modules — from design and development to testing and deployment.

What We're Looking For

Must-Have

• Bachelor’s degree in Computer Science, Engineering, or a related field.
• Strong Java fundamentals: 1–3 years hands-on with Java / Spring Boot. You understand the language deeply — not just syntax, but concurrency, memory management, and design patterns.
• Backend engineering mindset: You think in terms of systems, not just features. You care about correctness, performance, and how your code behaves on a scale.
• REST API & microservices expertise: You've built and consumed production APIs. You understand contracts, versioning, and failure handling.
• Git & CI/CD discipline: Version control best practices, branching strategies, and automated pipelines are second nature to you.
• Cloud experience: Familiarity with AWS services — ideally you've deployed something real on Lambda, API Gateway, or similar.
• Debugging & problem-solving: You dig into issues systematically and don't stop at surface-level fixes.

Why Join Us

• Work at the intersection of product engineering and technology partnerships.
• Opportunity to explore and integrate with global platforms like Adobe, Shopify, AWS, and more.
• Continuous exposure to modern tech stacks, microservices, and cloud-native architecture.
• Collaborative, innovation-driven culture where learning and experimentation are encouraged

If you have a strong CS foundation, real Java development experience, and want to work on backend systems that matter — we want to hear from you.
