Java Integration Developer - Secure API

Ability to develop new and innovative applications as well as debug and refactor existing code. Strong experience with Java , and JVM tuning is required. Demonstrated experience architecting, developing and deploying high-volume, multi-tiered, distributed mission critical applications is required. Strong software and system design skills are required. Relational database experience and demonstrated abilities in SQL and data modeling is required. 6 plus years experience

• Proven delivery of a production-like workload on OCI (not just diagrams), including:
  • IAM (dynamic groups, policies), compartments, tagging strategy
  • Networking: VCN/subnets, NSGs, routing, Load Balancer, DNS; WAF if internet-facing
  • Compute approach (they can propose): OKE, Compute/Instance Pools, Container Instances, or Functions
  • Data services selection (Autonomous DB/DB System/Object Storage as appropriate)
  • OCI Vault (secrets/keys), Logging, Monitoring/Alarms
  • Infrastructure as Code:
    Terraform preferred; ability to stand up dev/test/prod (or at least dev + prod) quickly.
  • CI/CD experience for build/deploy, plus environment promotion practices.

• Designing and implementing services that validate bearer tokens safely:
  • JWT validation (issuer/audience/signature/expiry) and/or opaque token introspection patterns
  • API Gateway / reverse proxy patterns, auth
    
    N/auth
    
    Z boundaries
  • OWASP Top 10 and API hardening:
  • Input validation, rate limiting, replay protection where relevant, secure CORS, dependency hygiene
  • Secure secrets handling (no tokens in code), rotation strategy, least-privilege access.

• Strong experience integrating with third-party enterprise apps via:
  • REST APIs, webhooks, batch jobs if applicable
  • Resiliency: retries/backoff, idempotency, timeouts, circuit breakers
  • Audit logging and traceability across systems
  • Ability to produce clear API contracts (OpenAPI), integration sequence diagrams, and error models.

Any other helpful information? Additional qualifications include:

• Experience integrating with Zoom Contact Center / Zoom Communications APIs (or similar CCaaS):
  • Webhook/event handling, verification, replay protection
  • Interaction lifecycle concepts (queues, agents, dispositions, transfers) as needed for your use case
  • Practical understanding of operational concerns: throttling, event ordering, incident/debug support.

• Demonstrated ability to deliver an MVP quickly:
  • Thin-slice scope definition, backlog creation, and prioritization
  • Working software demos on a cadence
  • Documentation and handoff (runbooks + deployment notes)
  • o PRD and design architecture
