roadmaps to successful delivery.

We are looking for strong cloud architects with deep expertise in AWS or Microsoft Azure. You don't need to be an expert in every cloud – strong architecture fundamentals, engineering experience, and the ability to solve complex client problems matter more.

Responsibilities:

• Lead solution architecture across presales, assessments, discoveries, and strategic client engagements.
• Work directly with client stakeholders, including engineering leaders, CIOs and CTOs, to understand business goals and translate them into technology strategies.
• Design scalable, secure, resilient and cost-effective solutions on AWS and/or Microsoft Azure.

• Perform architecture reviews and help teams resolve complex technical challenges.
• Contribute to N-iX cloud offerings, reference architectures, accelerators and reusable assets.
• Stay current with cloud and AI capabilities and help clients identify where emerging technologies can create practical value.

Requirements:

• 8+ years of experience in software engineering, cloud engineering or architecture roles.
• Strong hands-on architecture experience with AWS or Microsoft Azure.
• Proven experience designing and delivering enterprise-grade cloud solutions.
• Experience with cloud migration, application modernization or cloud-native transformation.

• Strong software engineering background.
• Experience with platform engineering and developer platforms.
• Experience designing AI/GenAI-enabled solutions using services such as Amazon Bedrock, Azure AI Foundry or equivalent platforms.

Certifications:

Relevant professional-level cloud certifications are an advantage, including:

• AWS Certified Solutions Architect – Professional
• Microsoft Certified: Azure Solutions Architect Expert (AZ-305)
• AWS/Azure DevOps, Security or related certifications
• Terraform, Kubernetes or architecture certifications
