Job Description
We are seeking a highly skilled Software Engineer to own and support all SQL, Kafka, and AMQ‑related responsibilities within our engineering ecosystem. This role is ideal for someone who thrives in data‑driven environments, understands distributed messaging systems, and can deliver reliable, scalable data solutions across the organization.
Responsibilities:
- Design, write, and optimize complex SQL queries, stored procedures, and database schemas to support application and analytics needs.
- Monitor database performance, identify bottlenecks, and implement tuning strategies (indexes, query restructuring, partitioning).
- Ensure data integrity, consistency, and security across all SQL‑related operations, including backups, migration scripts, and auditing.
- Build, maintain, and scale Kafka topics, partitions, schemas, and consumer/producer configurations.
- Develop and optimize Kafka producers and consumers, ensuring reliable, high‑throughput, low‑latency streaming pipelines.
- Implement monitoring, alerting, and troubleshooting for Kafka clusters, including lag analysis and message flow diagnostics.
- Manage and configure AMQ messaging components (queues, topics, durable subscriptions) to support asynchronous workflows.
- Develop and maintain message producers/consumers for AMQ, ensuring resilient delivery, retry logic, and error‑handling patterns.
- Oversee reliability, observability, and fault‑tolerance of all messaging systems (Kafka and AMQ), including failover, scaling, and disaster recovery considerations.
- Collaborate with cross‑functional teams to design event‑driven architectures, ensure proper data contracts, and integrate SQL/Kafka/AMQ components into larger platform services.
This is a hybrid position. Expectation of days in the office will be confirmed by your Hiring Manager.
