PostgreSQL and SQL Server are listed as interchangeable alternatives under the required qualifications ('PostgreSQL or SQL Server'); PostgreSQL is named first and used as the primary skill with SQL Server in alternatives.
'Distributed systems', 'event-driven architecture', 'message queues', and 'observability' are retained as skills because the JD gates on them with specific, concrete technical framing (event-driven architectures, message queues, eventual consistency, metrics/logging/tracing) rather than generic soft-skill language.
No specific cloud platform (AWS, GCP, Azure) is named despite the role being described as cloud-native; no cloud skill was emitted.
No degree requirement is stated anywhere in the posting.
