Key Responsibilities

• Collaborate with the client’s Solution Architect to design and implement innovative, cloud-first solutions

• Engage with cross-functional stakeholders to translate complex business needs into technical design and delivery
• Advise on emerging technologies and best practices to drive continual improvement
• Proven hands-on experience working in AWS environments, with a strong systems engineering background on Linux
• Comfortable switching between solution design, coding (especially infrastructure-as-code), and client engagement
• Demonstrated ability to deliver high availability, scalable, and performance-focused systems
• Excellent collaboration, communication, and organisation skills, with the adaptability to work effectively in a fast-changing, Agile environment
• Self-starter attitude with strong attention to detail, energy, tenacity, and ability to perform under pressure
• Exposure to DevOps practices and tooling (AI/ML, ElasticSearch, Big Data) is a plus
