System Architect Cloud

We’re building and evolving a cloud-native SaaS platform supporting the EV charging ecosystem at a national scale. It’s a production-grade platform with real traffic, payments, subscriptions, and strict requirements around availability, security, and scalability.

The platform is based on a microservices architecture, deployed in AWS, and designed as a multi-tenant, multi-region SaaS. The system is already live and continuously developed - the role focuses on architectural evolution, improving existing solutions, and designing new components in close collaboration with the client’s technical leadership.

• Experience as a System Architect or in a similar architectural role.
• Strong hands-on knowledge of microservices architecture and distributed systems.
• Practical experience with AWS, especially AWS Lambda and serverless solutions.
• Good understanding of cybersecurity in cloud-based systems.
• Experience designing SaaS platforms, including multi-tenant and multi-region architectures.
• Strong analytical mindset and ability to look at systems end-to-end.
• Experience working directly with clients - discussing requirements, reporting progress, and defending technical decisions.
• Fluent English (daily communication with international stakeholders).
• High awareness of business context and the ability to translate business requirements into technical solutions.

Nice to have:

• Experienced in using AI tools in day-to-day workflow.
• Experience with other serverless or cloud-native services.
• Background in system optimization and legacy system modernization.
• Familiarity with compliance or security standards relevant to SaaS platforms.

• Design and evolve a microservices-based system architecture.
• Work with AWS cloud services, focusing on serverless and scalable solutions.
• Design and maintain multi-tenant and multi-region SaaS architecture.
• Ensure a high level of security and compliance across the platform.
• Analyze existing systems and identify areas for improvement and optimization.
• Work directly with the client as a technical advisor.
• Translate business requirements into technical solutions (and explain technical constraints back to the business).
• Clearly communicate architectural decisions, progress, and risks.
• Proactively propose solutions and justify architectural choices with technical arguments.
