This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior System Engineer (Virtual Private Cloud Team) based in United Kingdom.
As a Senior System Engineer, you will help build and operate the core networking layer of a large-scale cloud infrastructure platform. You will work on the Virtual Private Cloud environment that enables secure, isolated and reliable connectivity for virtual machines and cloud workloads. Your work will directly support essential services including load balancing, firewalls, security groups, internet connectivity and private networking. You will develop both control-plane and data-plane components while improving the performance, scalability and resilience of critical network services. The role involves solving complex distributed networking challenges and automating interactions across multiple cloud services. You will work in a highly technical, international engineering environment where reliability is a core priority and your contributions can influence foundational cloud infrastructure. This is an opportunity to work on challenging networking problems while helping shape the future of large-scale AI and cloud platforms.
Accountabilities
- Develop and maintain control-plane and data-plane components for cloud network services.
- Build and improve core Virtual Private Cloud capabilities that provide reliable IP-based connectivity across cloud workloads and physical infrastructure.
- Increase the scalability, performance and reliability of critical networking services.
- Develop new networking functionality, including capabilities such as IPv6 support, service endpoints, VPC peering and Layer 7 load balancing.
- Improve internal system architecture and optimize interactions between networking and related cloud services.
- Design and implement automation for complex cross-service interaction scenarios.
- Conduct load testing and performance analysis to identify bottlenecks and ensure services operate reliably at scale.
- Investigate and resolve complex networking and system-performance issues.
- Develop high-performance, production-quality code for systems operating within a large-scale cloud environment.
- Contribute to the resilience and fault tolerance of networking infrastructure, ensuring services remain operational during partial system failures.
- Collaborate with other engineering teams to deliver reliable and secure networking capabilities across the broader cloud platform.
- Participate in technical discussions, design reviews and coding interviews as part of the engineering development process.
