DNS Engineer

DNS Engineer – 6-Month Contract – London – Immediate Start – £500 per day Outside IR35 Our client, a leading organisation undergoing significant infrastructure enhancement, is looking for an experienced DNS Engineer to join their IT team on a contract basis. This is a critical role focused on optimising and securing both internal and external DNS environments. If you are a highly skilled infrastructure engineer with a deep technical foundation in DNS architecture and security, this is an excellent opportunity to make a tangible impact within a complex enterprise environment. Working closely with the IT Infrastructure Manager and key stakeholders across the network and security teams, you’ll be responsible for conducting a comprehensive review of the existing DNS landscape. This includes identifying and removing legacy or stale DNS records and ensuring current configurations align with best practice standards. A major focus of this contract will be the implementation of DNS security enhancements, including DNSSEC and other mitigation strategies aimed at reducing exposure and risk across the network. The role will involve the creation and implementation of DNS subzones where necessary, as well as resolving any DNS-related issues that may arise. You’ll carry out detailed root cause analyses and help define long-term solutions to prevent reoccurrence. Strong documentation will also be key—this includes maintaining DNS configuration records, policy documents, and operational procedures that can be handed over to the permanent IT staff for future use. Collaboration will be vital, and you’ll work hand-in-hand with other technical specialists to ensure DNS services integrate effectively with broader infrastructure and security architectures. As part of the knowledge transfer process, you’ll be expected to upskill internal teams, providing guidance and training to build internal capabilities. We’re looking for an engineer with a comprehensive understanding of DNS record types, zone files, and resolution processes. You’ll have hands-on experience with enterprise DNS platforms such as BIND and Microsoft DNS, and a robust grasp of DNS protocol-level detail. Your background will include implementing security controls such as DNSSEC, TSIG, and ACLs, alongside familiarity with monitoring and logging DNS activity for compliance and threat detection. Applicants with scripting experience—whether in PowerShell, Bash, or Python—will find themselves well-suited to this position, particularly where automation and reporting are concerned. Exposure to cloud-based DNS services, including Azure DNS and advanced public DNS platforms, is also highly desirable. Certifications such as Infoblox Certified DNS Specialist or Microsoft Certified: Windows Server Hybrid Administrator Associate would be advantageous, but not essential for someone who can demonstrate strong practical knowledge. This is a 6-month initial engagement based in London, with an immediate start available. If you\’re ready to apply your expertise to a fast-paced environment with a focus on resilience, performance, and security, we’d love to hear from you.
