Your role
The DNS Engineer is a technical authority responsible for the design, reliability, security, and performance of enterprise and internet-facing DNS services. The role provides L3 escalation for complex DNS issues, leads root-cause analysis across multiple layers, and drives continuous improvement in DNS architecture, operational readiness, and service assurance.
This role works in a shared delivery environment, partnering with platform, infrastructure, automation, and security stakeholders to achieve end-to-end DNS outcomes.
You will play a key role in:
- Define and maintain DNS architecture, standards, and design patterns across authoritative and recursive DNS services.
- Ensure DNS correctness, resilience, and performance under normal operation and failure scenarios.
- Review and approve significant DNS changes and design decisions.
- Act as the escalation point for complex or systemic DNS incidents (intermittent failures, correctness issues, performance degradation).
- Lead deep diagnostics across DNS protocol behaviour, routing dependencies, client resolver behaviour, and platform/runtime interactions.
- Own DNS security design and assurance relevant to the DNS service, including DNSSEC strategy and operational readiness.
- Implement and govern policy-based controls (e.g., response policy / filtering approaches) where required.
- Define telemetry and monitoring requirements for DNS services (latency, response codes, error patterns, saturation indicators).
- Improve operational readiness through diagnostics, runbooks, and failure scenario testing.
- Provide DNS SME capability across multiple DNS delivery platforms, including:
- Open-source / software DNS servers (authoritative and recursive).
- F5 BIG-IP DNS deployments
- Translate DNS service requirements into actionable inputs for platform/infrastructure teams.
Your profile
- Typically, 8+ years with significant DNS depth.
- Demonstrated ability to operate as a senior SME and technical authority in a 24×7 production environment.
