- Uphold compliance with applicable laws, policies, and risk standards; demonstrate ethical judgment and transparency.
- Mentor junior engineers and influence engineering decisions through counsel and expertise.
- working in large-scale agile software development environments utilizing the SAFe framework (scrum methodology)
Qualifications:
- BE/BTech in Computer Science or equivalent experience.
- 8+ years in Engineering/IT; 3+ years in enterprise Java development; 3+ years with Splunk/ELK (or similar log analytics); 3+ years with Dynatrace or other APM.
- Java, Spring, Spring Batch, Spring Boot, Microservices, RESTful APIs, MVC architecture.
- Databases: Oracle, SQL (queries & stored procedures).
- Platform/infra: Java app servers, web servers, Linux/Unix, Docker, Kubernetes, Kafka, Redis; Cloud Foundry (plus).
- Expertise in building Dashboards/Views in Splunk and Dynatrace is a Plus
- CI/CD: Jenkins, Git, Maven; Agile/DevOps practices; experience in SAFe at scale.
- Production monitoring, observability, RCA, capacity planning (redline/load testing).
- Performance testing/tuning/analysis; JMeter, BlazeMeter (or equivalent); thread/heap dump analysis.
- Oracle Database SQL & configuration Tuning for Performance (indexes, hints, execution plan analysis, SQLT, AWR and similar report analysis)
- Hands on in large scale, complex, highly available distributed systems (web, relational & non relational DBs, cache, pub/sub, containers) with resiliency, graceful degradation, DR, and backpressure patterns.
- Clear written/verbal communication; stakeholder engagement across operations, developers, and performance testers.
- Analytical/diagnostic strength; ability to work independently, in a matrix/virtual environment, under pressure and tight deadlines.
- Proven record of operational process changes and continuous improvement.
- Commercial awareness with alignment to business outcomes.
- Influence the engineering function by providing guidance, expert advice, and facilitating services to support decision-making processes
- Demonstrated capability to operate effectively within a matrix organization and collaborate with virtual teams.
- Proven ability to work autonomously, manage multiple tasks simultaneously, and assume responsibility for various aspects of projects or initiatives.
- Skilled in performing under pressure and adept at meeting strict deadlines or adapting to changing expectations and requirements.
