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.
