Senior Platform Engineer (DNS Infrastructure) at Vultr

Vultr is seeking a highly skilled and experienced Senior Platform Engineer to own and evolve our critical DNS infrastructure. The ideal candidate is a seasoned infrastructure engineer with deep DNS expertise, strong Linux and networking fundamentals, and the ability to own and modernize complex internal services end-to-end.

This is a highly visible role in a high-growth technology company, which will require hands-on technical ownership of production DNS systems, collaboration across engineering teams, and the ability to drive the future direction of internal platform services including API development in PHP, Go, or Rust. This is your opportunity to join our fast-growing team and leave your mark on Vultr and the future of Cloud Infrastructure.

Key Responsibilities

• Own and operate Vultr's DNS infrastructure at scale, including recursive DNS (Knot Resolver), reverse DNS, authoritative DNS, and integrations with PowerDNS instances.
• Maintain and evolve the PHP-based DNS API, contributing to its long-term direction, including potential modernization in Go or Rust.
• Diagnose and resolve complex DNS and network incidents, serving as a subject matter expert across the organization.
• Drive automation and infrastructure-as-code practices across platform services, reducing toil and improving reliability.
• Collaborate with network and infrastructure teams on adjacent systems including BGP route reflectors and broader platform tooling.
• Contribute to observability and operational excellence by leveraging the team's monitoring stack (Grafana, Loki, Mimir) to improve visibility into DNS and platform service health.

Qualifications

• 5+ years of experience in platform, infrastructure, or systems engineering in a production environment.
• Deep hands-on experience with DNS at scale — including recursive and authoritative DNS, DNSSEC, zone management, and troubleshooting complex resolution failures.
• Strong Linux systems engineering fundamentals including networking, service management, and operational ownership of production services.
• Experience building or maintaining APIs or automation layers, with proficiency in PHP and/or Go or Rust.
• Demonstrated experience with infrastructure-as-code and configuration management tooling (Terraform, Ansible, or similar).
