DNS Architect

The purpose of this role is to review and improve DNS architecture across hybrid environments, identifying risks, gaps, and technical debt-without implementing changes. This work will influence how the organisation reduces failure risk, strengthens trust boundaries, and improves operational consistency across multiple DNS providers and platforms. Review end-to-end DNS architecture across on-prem, cloud, andSaaS platforms Assess configuration alignment and consistency across multiple DNS providersIdentify architectural gaps, risks, and areas of technical debt Analyse resiliency and redundancy within the currentDNS model Evaluate single-provider dependency risksPropose multi-vendor DNS architecture approaches to eliminate single points of failureConsider active/active and active/passive patternsMap failure domains across platform, provider, region, and control-plane boundaries Assess alignment with industry standardsReview the architecture against recognised best practicesEvaluate scalability, separation of concerns, and operational consistency Create current-state and future-state architecture viewsProduce conceptual future-state architecture guidanceDefine prioritised improvement areasDevelop a phased roadmap (advisory only-no implementation) Lead DNS security architecture and risk analysis (with support from security engineers) Perform DNS threat modelling using a STRIDE-style approachAssess control-plane access and trust boundariesAnalyse provider dependencies across control-plane and data-planeIdentify misconfiguration risks in SaaS DNS platformsDocument failure modes and abuse cases (non-adversarial; no active testing) Use telemetry to strengthen findings (no new tooling) Review existing DNS telemetry and logsCorrelate latency, error rates, and query trendsIdentify resilience patterns, cascading failures, and hidden dependenciesSupport recommendations with empirical evidence Experience with one or more majorDNS/platform technologies such as: BlueCatAkamaiF5 (including GTM/LTM)AWS Route 53Azure DNSPrior experience delivering architecture assessments that result in future-state roadmaps (conceptual, non-implementation)Experience creating structured outputs such as threat and failure matrices, dependency registers, and risk reduction summaries If you're an experienced DNS Architect and enjoy advisory work that blends architecture, resiliency, security, and evidence-based analysis, we'd love to hear from you.
