• Collaborate closely with architects, product managers, and cross-functional teams to translate business requirements into scalable technical solutions.
• Build and evolve RESTful APIs, microservices, and event-driven systems, ensuring strong service contracts and backward compatibility.
• Champion engineering excellence by improving CI/CD pipelines, test automation, and developer productivity.
• Proactively identify system bottlenecks, debug complex issues, and drive root-cause analysis with long-term fixes.
• Design systems for scalability, resilience, and observability, including monitoring, logging, and alerting strategies.
• Contribute to cloud-native adoption, including containerization, infrastructure-as-code, and auto-scaling architectures.
• Influence technical direction and challenge the status quo by proposing innovative, pragmatic solutions.
• Take ownership and accountability for delivering high-impact outcomes aligned with team and organizational goals.
