- Guide features through design, development, testing, release, and production support
- Drive high standards across code quality, testing, deployments, and operational readiness
- Identify and mitigate delivery, stability, and dependency risks
* Architecture & modernization
- Evolve system architecture across monolith and microservices environments
- Define APIs, integration patterns, and event-driven/data flow designs
- Drive modernization while maintaining platform stability and availability
- Embed resilience patterns such as fault tolerance, graceful degradation, and safe rollouts
- Production reliability
- Act as an escalation point for technical issues and incidents
- Lead root cause analysis and implement long-term fixes
- Improve reliability through observability, refactoring, and operational best practices
- Cross-team collaboration & engineering standards
- Collaborate across teams to align delivery and integrations
- Clarify ownership across shared services and legacy systems
- Set engineering standards and provide technical guidance through design, code, and test reviews
* Tech stack & environment
Java (Spring Boot), monolithic and microservices architectures, REST/event-driven integrations, CI/CD (Jenkins), cloud platforms (PCF/Kubernetes), Oracle databases, observability (Dynatrace/Splunk), and secure SDLC tooling (Sonar, Checkmarx, Black Duck).
* Must-have
- Strong backend engineering background (8+ years) with experience across system design and delivery
- Experience working with both monolithic and microservices-based systems
- Proven ability to lead technical delivery in complex, distributed environments
- Strong problem-solving and debugging skills across multiple system layers
