Summary:
Redsky is the high-scale engine powering the company's digital product data—pricing, promotions, and fulfillment. We are looking for a highly skilled Contract Software Engineer to provide immediate engineering capacity for critical platform modernization efforts.
You will be a key contributor to the team, focusing on the "heavy lifting" of migrating our high-scale Kotlin services into the company'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 GCP/Kubernetes configurations to the standardized company Application Platform in GCP, ensuring zero-downtime deployments.
• GitHub Migration: Own the end-to-end migration of repositories between the company's 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.
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. - **Only those lawfully authorized to work in the designated country associated with the position will be considered.**
