Designation: Senior Software Engineer I

Job Responsibilities:

Technical Contributions & Collaboration:

• Take end-to-end ownership of data ingestion pipelines from source-system CDC all the way through enrichment, publishing, and downstream consumption.
• Design and build reactive microservices (Spring WebFlux + R2DBC) that consume Kafka streams, enrich events against DB2 and PostgreSQL, and publish enriched records to downstream topics and data stores.
• Configure and operate CDC tooling (Qlik Replicate and similar) including source/target endpoint setup, task definitions, transformation expressions, and lookup-based enrichment patterns.
• Participate in code and design reviews; provide constructive feedback that raises the quality bar across the team.
• Mentor junior engineers on reactive programming concepts, streaming patterns, and data-pipeline best practices.
• Collaborate closely with QA, DevOps, Data Engineering, and business analyst teams; communicate technical decisions clearly to both technical and non-technical stakeholders.

Delivering Technology:

• Analyze complex data-flow requirements and translate them into pipeline designs that balance latency, throughput, cost, and operational simplicity.
• Validate requirements are complete and unambiguous before solutioning; push back when they aren't.
• Build and maintain Airflow DAGs and Python utilities that orchestrate batch workflows, reconciliation jobs, and data-quality checks.
• Ensure pipelines are resilient to source outages, schema evolution, poison messages, and replay scenarios.
• Participate in production support rotations, triage incidents across the Java services / Kafka / DB2 / PostgreSQL stack, and drive root-cause analysis.
• Coordinate with Operations and Infrastructure teams for deployments, scaling events, and production support.
• Proactively flag risks, blockers, and tech debt to leads and stakeholders.

IT Governance:

• Follow defined IT standards, architectural guidelines, and change-management processes.
• Maintain a healthy balance between shipping speed and operational risk especially around data correctness, replay safety, and backward compatibility of events.
• Adhere to secure coding practices, including proper handling of PII and credentials in pipelines, logs, and error tables.
• Follow project management standards and keep work visible through Jira / sprint cadences.

Skill and Experience:

• 4+yearsof hands-on software engineering experience with a strong focus ondata-movement / streaming / integrationsystems (not just CRUD application development).
• 4+ yearsof hands-on Java / Spring Boot development, including meaningful experience withreactive programming(Spring WebFlux, Project Reactor, R2DBC).
• Proven experience designing and operatingKafka-based pipelines topic design, consumer group tuning, partition strategy, exactly-once / at-least-once trade-offs, schema evolution with Avro + Schema Registry.
• Hands-on experience with aCDC toolsuch as Qlik Replicate, Oracle GoldenGate, Debezium, or AWS DMS including source/target endpoint configuration, transformation expressions, and troubleshooting latency or replay issues.
• StrongSQL proficiencyon bothIBM DB2(preferably z/OS or iSeries) andAurora PostgreSQL able to read query plans, optimize joins, and design indexes deliberately.
• Pythonexperience sufficient to author and maintainAirflow DAGs, operators, and data-quality / reconciliation utilities.
• Production experience withAWScore services (at minimum EC2, S3, IAM, MSK or self-managed Kafka, Aurora, CloudWatch, Secrets Manager).
• Solid experience withCI/CD(Jenkins or GitHub Actions), containerization (Docker), and orchestration (Kubernetes or ECS).
• Proficiency withunit and integration testing JUnit 5, Mockito, Reactor Test; familiarity with testcontainers or embedded broker patterns is a plus.
• Exposure toobservability tooling Dynatrace, Grafana, Splunk and the discipline to add meaningful logs, metrics, and traces to new services.
• Comfort withGit / Bitbucket,Swagger / OpenAPI, andSonarQubequality gates.
• Ability to write clear technical documentation design docs, runbooks, pipeline specs that a teammate can read a year from now and still act on.
• Experience working in anAgileenvironment with an onshore / offshore model.
• Strong troubleshooting and defect-triage skills that span across Java code, SQL, Kafka, and infrastructure layers.

Nice to Have:

• Experience withSnowflake,Databricks, or another cloud data warehouse as a CDC target.
• Familiarity withKEDAor event-driven autoscaling for Kafka consumers.
• Experience withAvro schema evolutionand backward/forward compatibility strategy.
• Exposure tomainframe-adjacentconcepts DB2 for i triggers, journals, logstreams or a willingness to learn them.
• Prior work onLoyalty,Reservations, or similarly high-cardinality customer-data domains.

Education and Certifications:

• Undergraduate degree in Computer Science, Engineering, or equivalent practical experience.
• AWS certifications (Developer Associate, Solutions Architect Associate, or Data Engineer) are a plus but not required.

Education and Certifications:

• Undergraduate degree or equivalent experience/certification.
