Job Summary

8+ years production Python; services and batch jobs you were personally on call for
Oracle: strong SQL, bind variables, bulk DML, execution-plan reading; oracledb / cx_Oracle
RHEL fluency: bash scripting, cron/systemd, process and log forensics, packaging and deployment
IBM MQ (pymqi) and Solace (solace-pubsubplus): queues, topics, redelivery, poison messages, backlog drainage
Enterprise integration patterns: pub/sub, request-reply, guaranteed delivery, idempotency, replay, reconciliation and acknowledgement write-back
REST API design and consumption; auth, retries, timeouts, backpressure
Confident with JSON, XML (XSD, XPath, namespaces) and CSV at volume, parsing, generating and validating
Effective, disciplined use of AI coding tools such as Claude Code and Copilot: scoped prompts, repo context, reviewed and tested output, never unverified code into a release
pytest, Git, code review, and clear written design notes

Nice to have

SWIFT MT/MX message formats and settlement messaging
Securities lending, repo, collateral or post-trade settlement domain knowledge
HashiCorp Vault, Control-M or Tidal, Jenkins, Maven, Nexus
pandas and openpyxl for data work; Sybase or SQL Server
Reading C++ or Java well enough to trace a message through vendor code
