Platform & Security Solution Architect

The opportunity

We are looking for an experienced Platform and Security Solution Architect to support several upcoming pieces of AWS platform and security work.

This is a senior contract role requiring someone who can work across cloud infrastructure, enterprise networking, cyber security and architecture advisory.

You will engage with business and technical stakeholders, coordinate across internal teams and external providers, and produce clear architecture recommendations and implementation roadmaps.

An immediate focus will be leading an options assessment for Security Data Lake capabilities. This will include evaluating AWS Security Lake, Microsoft Sentinel, Databricks and alternative approaches. Direct experience with every product is not required, but you will need the architecture experience and analytical capability to assess the options and develop a well-supported recommendation.

Key responsibilities

• Lead an options assessment for Security Data Lake capabilities
• Evaluate AWS Security Lake, Microsoft Sentinel, Databricks and alternative approaches
• Engage with Cyber Security, Security Operations, Enterprise Architecture and Platform teams
• Produce recommendation papers, architecture artefacts, cost models and implementation roadmaps
• Support ongoing AWS migration and platform architecture activity within the Platforms domain
• Architect the migration of on-premises infrastructure, applications and services to AWS
• Facilitate workshops, gather requirements and present recommendations to technical and executive audiences
• Manage and coordinate vendors, service providers and internal delivery teams
• Produce high-level and detailed designs, architecture decision records, option assessments, business cases, roadmaps and presentations
• Balance architectural, operational, financial and security considerations when making recommendations

Experience we’re looking for

• Experience architecting and delivering migrations of on-premises infrastructure, applications and services to AWS
• Experience designing core cloud infrastructure and platform services in AWS, including Active Directory, DNS, DHCP, virtual networking, firewalls, identity services and security controls
• Experience with AWS Direct Connect, network service providers such as Megaport, hybrid connectivity patterns and enterprise network architecture
• Strong understanding of zoned security architecture, zero trust principles, identity-centric security models and cloud security best practice
• Experience designing or evaluating security monitoring, security telemetry and log management platforms across cloud and hybrid environments
• Experience undertaking options analysis for SIEM, SecOps, Security Data Lake or comparable security platforms
• Understanding of cyber security operational processes, including threat detection, incident response, security monitoring, vulnerability management and forensic investigation requirements
• Experience with data platforms, data ingestion pipelines, retention strategies, classification models and integration patterns for security or operational data
• Strong stakeholder engagement and workshop facilitation skills
• The ability to communicate effectively with both technical and executive audiences
• Experience coordinating multiple vendors, service providers and internal delivery teams
• Strong architecture documentation and presentation skills

Experience with one or more of the following would be valuable:

• AWS Security Lake
• Microsoft Sentinel
• CrowdStrike
• Microsoft Defender
• Databricks
• Security analytics and observability platforms

You do not need experience with every technology listed. We are looking for someone with the broader platform and security architecture capability to assess the environment, evaluate the available options and develop practical recommendations.

If you are a senior architect with strong AWS platform experience, sound security knowledge and the ability to bring clarity to complex technology decisions, we would like to hear from you.
