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.
