Network Architect
Flutter InternationalJob title: Network Architect
Location: Sofia, Bulgaria
Overview of the role:
Flutter Technology is seeking a Cloud Network Architect to lead the definition and governance of our global cloud network architecture. This role is critical in ensuring our multi-region AWS network designs are secure, scalable, reliable, and operable, enabling Flutter’s divisions and brands to deliver at pace.
As a Cloud Network Architect, you will own the architectural direction for Flutter’s Global Network and hybrid connectivity patterns, setting standards and reference designs for routing, segmentation, ingress/egress, inspection, and IP address management. You will work closely with Engineering and Architecture peers to validate implementation feasibility and ensure designs can be delivered and operated at scale.
You will engage with senior stakeholders, security, and platform teams to align network architecture initiatives to business objectives and regulatory requirements. You must be effective at articulating architectural decisions and trade-offs, promoting cloud networking best practices, and applying methodologies required to reduce risk and achieve desired outcomes in a complex, multi-divisional environment.
The right candidate will have extensive experience designing enterprise AWS cloud network architectures, modernising hybrid connectivity, and defining secure network patterns using cloud-native services, with a passion for transforming infrastructure through automation and platform thinking.
This role follows a hybrid approach to working, allowing you to combine working from home with working in our modern offices. These discussions are between you and your manager to find the best pattern for you both, while recognising that quality time together is essential for keeping us mission-aligned.
