AWS Solutions Architect Tech Lead

Our client is a leading provider of smart metering solutions serving approximately 800 customers through their infrastructure. The company is experiencing rapid growth with revenue projected to scale from €3M to €55M by 2030. Currently operating entirely on-premises infrastructure in a communication datacenter, they face critical scalability and cost challenges that require immediate modernization. 

Key Business Challenges: 

• Hosting costs consuming 20% of software & services revenue (industry standard: 8-12%)
