About the Role: We are looking for an experienced and highly skilled Lead Technical Architect with expertise in cloud-based architectures to join our team.
You will play a pivotal role in designing, implementing, and overseeing advanced cloud infrastructure solutions for mission-critical systems.
With at least 8 years of experience, including deep knowledge of security architecture on cloud platforms, you will provide technical leadership and strategic direction in building scalable, secure, and resilient cloud-native systems based on AWS, Kubernetes, Kafka, microservices, Java, and event-driven design.
Key ResponsibilitiesCloud Architecture Design: Lead the design of cloud-based systems and solutions, utilising AWS and modern architectural patterns such as microservices, event-driven architectures, and serverless computing to meet both current and future business needs.Cloud Security: Develop and implement robust security architectures for cloud solutions, ensuring data protection, regulatory compliance, and alignment with industry best practices (e.g., AWS IAM, encryption, VPC, security monitoring, and auditing).Containerisation & Orchestration: Architect and oversee containerised environments using Kubernetes, ensuring high availability, scalability, and fault tolerance for critical applications.Event-Driven Systems: Architect event-driven systems using Kafka, designing and managing messaging frameworks to handle real-time data processing across distributed microservices.Microservices Architecture: Design and oversee the development of microservices-based systems, establishing best practices for modularity, scalability, and maintainability, with a focus on Java-based backend services.Technical Leadership: Provide technical leadership and mentorship to architecture and development teams, guiding them through complex technical challenges and architectural decisions.Security & Compliance: Ensure that cloud architectures are compliant with industry regulations (e.g., GDPR, HIPAA) and company security policies, and implement security controls across the infrastructure.CI/CD & Automation: Champion the development of CI/CD pipelines, infrastructure as code (IaC), and automation to enable fast and reliable delivery of cloud services.Work closely with DevOps, engineering teams, product management, and stakeholders to ensure that architectural strategies align with both technical and business objectives.Performance & Cost Optimisation: Drive performance tuning, cost optimisation, and cloud resource management strategies to maximise efficiency and minimise cloud spend.Risk Management: Identify and mitigate technical risks in cloud-based systems and infrastructure.Documentation & Best Practices: Develop and maintain architectural standards, design patterns, and documentation, ensuring a shared understanding of technical solutions. Skills, Knowledge and ExpertiseDegree in Computer Science, Software Engineering, Information Technology, or a related field or professional equivalent maybe considered.8+ years of experience in designing and implementing large-scale, distributed cloud systems, with a strong focus on AWS.Extensive experience with cloud security architecture, including knowledge of AWS security best practices (e.g., IAM, network security, encryption).Deep expertise in containerisation technologies (Docker) and Kubernetes for orchestration in production environments.Proven experience in designing and implementing event-driven architectures, with strong expertise in queue-based systems including Kafka.Strong background in microservices architecture and hands-on experience with Java-based backend systems.In-depth understanding of CI/CD pipelines, infrastructure as code (e.g., Terraform, CloudFormation), and automated deployment processes.Excellent communication and leadership skills, with the ability to collaborate effectively with cross-functional teams and provide technical mentorship.Experience with monitoring and logging tools (e.g., Prometheus, Grafana, ELK Stack) and cloud cost optimisation strategies. Preferred Skills:AWS certification(s) (e.g., AWS Certified Solutions Architect, AWS Certified Security – Specialty).Experience with other cloud platforms (e.g., Azure, GCP).Familiarity with serverless architectures and AWS Lambda.Expertise in compliance standards such as GDPR, HIPAA, SOC2, and ISO 27001.Experience with advanced security practices such as zero-trust architecture, encryption key management, and security incident response. Why Apply?Leadership role with the ability to influence key architectural decisions.Opportunity to work on cutting-edge cloud technologies and large-scale projects.Competitive salary and comprehensive benefits package.Continuous learning and development opportunities, including cloud certifications.Training allowance.A collaborative and innovative work environment.Please submit your CV along with a cover letter detailing your experience in cloud architecture, security, and relevant technologies.
