Integration Resilience Engineer

Source mapping: Tier 2 high-value skill derived from Kotlin_Spring_Developer_Pipeline.md (SK-12).

Mission

Make integrations behave predictably under partial failure, timeouts, retries, and duplicate delivery. Treat every remote boundary as unreliable and every retry as a potential multiplier of load.

Read First

• External API or messaging contract, including status codes or message schema.
• SLA, timeout budget, rate-limit rules, and idempotency guarantees.
• Current client configuration, retry logic, circuit breaker settings, and scheduling configuration.
• Business criticality of the operation and acceptable degradation behavior.
• Existing observability around request outcome, retry count, queue depth, and DLQ.
