Application Production Support Engineer (L3, Java Applications)
Location: Poland
Work Model: Hybrid (1 day a week in the office at any Cognizant location)

We’re expanding our production support team to strengthen the stability and performance of large-scale Java microservices in the financial domain. As a global tech partner with over 30 years of experience, Cognizant helps leading organizations modernize their systems and deliver exceptional digital experiences.

About the Role
We’re looking for a skilled and reliable Application Production Support Engineer (L3) to maintain and support complex Java-based microservices. This role is critical to ensuring system continuity and performance in a dynamic fintech environment. You’ll collaborate closely with development and product teams to investigate incidents, identify root causes, and implement fixes or workarounds. While infrastructure management is not part of the role, familiarity with DevOps tools like Docker and Kubernetes is a plus.

Key Responsibilities
Troubleshoot and resolve production issues in Java microservices

Analyze JIRA tickets, perform root cause analysis, and apply fixes

Make minor code corrections or database updates (PostgreSQL, MySQL, MongoDB, Redis, ElasticSearch)

Collaborate with Development and Product teams to ensure long-term system stability

Document incident analysis, fixes, and escalation paths clearly

Participate in regular maintenance and monitoring activities

Tech Stack
Backend: Java, Spring Boot, Microservices

Messaging: Kafka

Databases: PostgreSQL, MySQL, MongoDB, Redis, ElasticSearch

Tools (nice to have): Docker, Kubernetes

Workflow: JIRA, Confluence, Git

Who You Are
A methodical problem solver who thrives on restoring system stability

Comfortable reading and lightly modifying Java code

Prefer structured work hours (9–17) over reactive firefighting

Communicate clearly and collaborate effectively across teams

What We Offer
Stable role with a well-defined scope (no 24/7 on-call)

Opportunity to deepen expertise in enterprise-scale systems

Exposure to modern fintech architectures and technologies

Long-term contract with competitive compensation and development support

The Role in Perspective
This isn’t a role for building new systems or driving DevOps innovation — it’s about keeping critical production systems running smoothly at scale. Ideal for engineers who value technical depth, reliability, and a predictable work rhythm in a high-impact financial environment.
