• Collaborate with platform, AI/ML, and infrastructure teams to evaluate system health, performance, and failure patterns.
• Build automation and tooling that improves deployment repeatability, enhances resiliency, and reduces operational toil.
• Develop and maintain automated testing suites and regression test beds to validate functionality, resiliency, and performance.
• Participate in incident management, troubleshooting, and root-cause analyses, and contribute to recovery and prevention strategies.
• Contribute to architectural discussions and design reviews, influencing decisions related to scalability, fault tolerance, and non-functional requirements.

Kore.ai SaaS Migration Responsibilities:

• Support and contribute to the migration of the Kore.ai conversational AI platform from on‑prem to the Kore.ai SaaS offering.
• Partner with vendor and Vanguard engineering teams to analyze platform gaps, data flows, integrations, security requirements, and service dependencies related to the migration.
• Assist in the design and execution of migration test plans, including functional, resiliency, and performance validation in the SaaS environment.
• Develop and enhance automation, telemetry, and regression tests specific to the Kore.ai SaaS platform.
• Support cutover planning, environment readiness, UAT coordination, and post-migration stability monitoring.
• Contribute to documentation, runbooks, and operational readiness deliverables for the SaaS environment.

Qualifications:

• Minimum of eight years related experience, with at least two years of development experience.

• Undergraduate degree or equivalent combination of training and experience. Graduate degree preferred.

• Strong proficiency in Java or Node.js; experience with APIs, multithreaded applications, and GraphQL.
• Experience building automated testing frameworks (unit, integration, resiliency, performance) and maintaining regression test beds.
• Experience with observability frameworks/tools such as OpenTelemetry, CloudWatch, Grafana, and Splunk.
• Familiarity working with SaaS platforms, including designing integrations and implementing observability for SaaS-based products.
• Experience with containerized and microservices architectures (e.g., Docker) and distributed systems.
• Working knowledge of AWS networking, application services, IAM concepts, and cloud-native patterns.
• Comfort with *nix environments, scripting, and command-line tooling.
• Strong ability to diagnose system issues in high-throughput, mission-critical applications.
