What are the responsibilities and job description for the Java Software Engineer position at Apexon?
Role Overview
We are seeking a Software Engineer to contribute to the resilience, scalability, and operational excellence of our Corporate Actions (GASS) platform. The platform processes voluntary and mandatory corporate action events — dividends, mergers, splits, rights issues, spin-offs, tender offers, and elections — across the full lifecycle from event capture and entitlement calculation through position impact, client notification, booking, and downstream publication. Built on a heterogeneous stack spanning C , Java, Kafka, Sybase, Perl, Autosys, ProcMon, and MongoDB, the platform demands precision, auditability, and deterministic processing at every stage.
