• Collaborate with cross-functional teams; produce clear technical documentation and communicate status, risks, and design decisions.

• Integrate with communication platforms:

• SMS providers (e.g., Syniverse/Twilio)

• Email delivery platforms (e.g., SparkPost) and compliance/security integrations (Proofpoint/DMARC)

What We’re Looking For

• Strong object-oriented design and coding skills.

• Experience with containerization and platforms: Docker and OpenShift.

Preferred Qualifications

• Direct experience on migration projects upgrading JDK 8/11 → JDK 17 (compatibility, dependency upgrades, testing, performance tuning).

• Deeper hands-on with Kafka in production (streams, consumer groups, retries/DLQ patterns, schema evolution).

• Strong experience with SQL Server, plus exposure to NoSQL databases and XML-capable storage/querying patterns.

• Experience integrating with SMS platforms (Syniverse, Twilio) including delivery callbacks, templates, opt-in/opt-out, compliance.
