Project description:

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.

Main responsibilities:

• 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.
