• Lead technical design and architecture for complex, cross-functional features — evaluating trade-offs, defining patterns, and ensuring solutions are scalable, maintainable, and performant across a large enterprise-grade codebase.
• Build and own platform-level frameworks used by other engineering squads — including authentication/authorization systems, API development tooling, webhook infrastructure, messaging pipelines, AI integrations, and CI/CD tooling.
• Drive engineering excellence through code reviews, architectural guidance, and establishing best practices that raise the bar for the entire team.
• Mentor and develop junior and mid-level engineers through pairing, design reviews, and knowledge sharing — fostering a culture of continuous learning (teaching experience a strong plus).
• Own end-to-end delivery of features from design through production — writing clean, efficient, well-documented code in Java, Kotlin, and Type Script adhering to team standards.
• Lead and execute complex integrations with third-party systems — including payment processors, identity providers, OEM data feeds, and external APIs — ensuring resilience, security, and maintainability.
• Champion performance and reliability — proactively identify and resolve bottlenecks, design for failure, and implement resilience patterns (circuit breakers, caching strategies, backoff/retry) across our service integrations.
• Drive cloud infrastructure decisions on AWS — including serverless architecture (Lambda, API Gateway), container orchestration (EKS), messaging (SNS/SQS, Rabbit
  
  MQ), and data services (RDS Postgre
  
  SQL, Elasti Cache/Redis, Dynamo
  
  DB).
• Manage and evolve CI/CD pipelines — automating build, test, and deployment processes using Git Lab CI, Gradle, Terraform, and Serverless Framework to enable rapid, consistent releases across environments.
• Lead incident response and root cause analysis for high-severity production issues, translating findings into actionable architectural improvements.
• Contribute to infrastructure as code using Terraform, supporting reproducible, version-controlled AWS environment provisioning.
• Maintain and improve technical documentation in Confluence, ensuring architectural decisions, patterns, and runbooks are accessible and up to date.
• Evaluate and adopt emerging technologies — including AI/ML tooling — making recommendations that align with long-term platform direction.

• Bachelor's degree in Computer Science, Engineering, or a related field with 7+ years of professional software engineering experience; or equivalent experience in lieu of a degree.
• Deep expertise in Java / Kotlin / Groovy and the Jakarta EE ecosystem — including JPA, Wildfly/JBoss, or Spring — with a strong command of object-oriented and functional design principles.
• Strong proficiency in Type Script and JavaScript — including Node.js and modern backend frameworks such as NestJS — with the ability to contribute across the full stack.
• Demonstrated ability to architect and deliver distributed, cloud-native systems at scale — including microservices, event-driven architectures, and RESTful API design.
