You will be a key contributor to the team, focusing on the "heavy lifting" of migrating our high-scale Kotlin services into client's standardized platform environment. This includes owning the transition of repositories between GitHub hosts, rebuilding CI/CD pipelines, and modernizing our observability by migrating Micronaut applications from Zipkin to OpenTelemetry (OTel).

Core Responsibilities (The Execution Mission) Platform Migration: Execute the technical transition of mission-critical services from legacy/custom Google Cloud Platform/Kubernetes configurations to the standardized Client Application Platform in Google Cloud Platform, ensuring zero-downtime deployments. GitHub Migration: Own the end-to-end migration of repositories between client internal Git to GitHub, ensuring all dependencies, permissions, and integrations are maintained. Observability Upgrade: Lead the implementation of OpenTelemetry (OTel) for Micronaut applications, transitioning away from legacy Zipkin tracing to modern standards. Feature & Performance Work: Contribute to the development and tuning of high-traffic Kotlin services, ensuring sub-millisecond response times and high reliability. System Maintenance: Use Grafana and Kibana to monitor service health during migrations, proactively troubleshooting any bottlenecks or latency spikes. Data Execution: Work with high-performance Key-Value stores (Valkey/Redis) to ensure data models are optimized and attributed correctly.

Core Languages: Expert-level Kotlin (preferred) or Java. Hands-on experience with Micronaut or Spring Boot. Observability: Deep experience with OpenTelemetry (OTel) and Zipkin. Proficiency in Grafana and Kibana. Cloud & CI/CD: Strong experience with Google Cloud Platform and Kubernetes. Proven ability to build/modify pipelines using standard CI/CD tools and GitHub-based workflows. Data Stores: Proficiency with Valkey or Redis. Nice-to-Have: Experience with RocksDB or similar persistent key-value storage. Testing: Experience with Kotest or similar automated testing frameworks to ensure a high-quality "definition of done."

Success Profile Execution Focused: You enjoy the "migration" work-moving repos, fixing pipelines, and modernizing libraries. Independent Contributor: You can navigate complex technical tasks with minimal oversight and provide high-quality, production-ready code. Migration Experience: You have a clear "definition of done" for migrations, focusing on validation, observability parity, and zero-downtime deployments. Standardization Mindset: You understand the value of moving from custom/legacy setups to enterprise-standard platforms and tools.
