• Collaborate cross-functionally: Partner with product, analytics, and fellow engineers to shape solutions and deliver reliably.
• Architect for change: Design and build backend systems that are scalable, modular, and resilient to evolving product and business needs.
• Improve Performance & Quality: Strengthen reliability, maintainability, observability, and operational excellence across critical services and workflows.
• Build clean data flows: Create dependable APIs, events, and service boundaries that support partner integrations, experimentation, analytics, and downstream systems.
• Lead AI-assisted development: Use AI tools for prototyping, scaffolding, refactoring, and exploratory development, then validate the output with strong engineering judgment.
• Raise quality through testing: Build and maintain automated test coverage across unit, integration, contract, and end-to-end layers.

About You

• Strong expertise in Java, Spring Boot, and modern backend architecture.
• Comfortable designing and operating RESTful APIs, microservices, and distributed systems in production.
• Strong working knowledge of SQL and NoSQL databases.
• Familiarity with asynchronous and event-driven systems such as Kafka, SQS, or similar technologies.
• Comfortable working in modern development environments, including Git-based workflows, containerized services, and cloud infrastructure (AWS, Kubernetes).
• Strong grasp of reliability, observability, maintainability, and performance.
• Familiarity with testing, CI/CD, monitoring, and modern development workflows.
• Skilled at partnering with Product, Analytics, and engineering teams to deliver in a fast-paced environment.
• Strong communication skills and a collaborative, problem-solving mindset.
