Description

Key Responsibilities

  • Design and develop a custom control plane for orchestrating Microsoft Hyper-V hosts and virtual machines, following Kubernetes-style declarative, reconciliation-loop architecture patterns
  • Build core control plane components in Go, including API servers, controllers/operators, schedulers, and reconciliation loops
  • Design and maintain the relational database schema used for cluster state, VM inventory, host topology, and configuration data
  • Implement custom Kubernetes Custom Resource Definitions (CRDs) and controllers where Kubernetes itself is used as (or alongside) the orchestration layer
  • Build robust, idempotent reconciliation logic that keeps actual infrastructure state in sync with desired state
  • Develop APIs (REST/gRPC) for internal and external consumers to interact with the control plane
  • Implement observability (metrics, logging, tracing) for control plane health, VM scheduling decisions, and host resource utilization
  • Design for high availability, failure recovery, and safe concurrent operations across a fleet of Hyper-V hosts
  • Write unit, integration, and end-to-end tests for control plane components; participate in code reviews
  • Collaborate with infrastructure, platform, and SRE teams to define scheduling policies, resource quotas, and placement constraints
  • Document architecture decisions, APIs, and operational runbooks for the platform

Required Qualifications

  • Bachelor's degree in Computer Science, Engineering, or equivalent practical experience
  • 4+ years of software engineering experience, with a strong focus on infrastructure or platform software (not just application development)
  • Strong proficiency in Go (Golang), including concurrency patterns (goroutines, channels), interfaces, and building production-grade services
  • Hands-on experience with Kubernetes internals or ecosystem — writing controllers/operators, working with the client-go library, CRDs, and the controller-runtime/reconciliation pattern
  • Strong experience with relational databases (e.g., PostgreSQL, SQL Server, MySQL) — schema design, transactions, migrations, and writing performant queries from Go
  • Experience designing and building distributed systems: state reconciliation, eventual consistency, leader election, and failure handling
  • Experience building and consuming REST or gRPC APIs
  • Working knowledge of Git-based development workflows, CI/CD pipelines, and automated testing practices
  • Strong debugging and systems-level troubleshooting skills across compute, storage, and networking layers
