Résumé du poste

Jobgether is seeking a Senior System Engineer (Virtual Private Cloud Team) based in France to design, build, and operate the core networking layer of a large-scale cloud platform. You will work on virtual private networking for reliable connectivity across distributed data centers, with Go for control-plane and C for dataplane components, using open-source technologies.

You will contribute to secure networking services including virtual networks, load balancers, firewalls, security groups, and

Qualifications

• Significant experience in systems engineering, network engineering, infrastructure engineering, or a closely related technical discipline.
• Strong ability to write reliable, efficient, and high-performance concurrent code.
• Proficiency in Go (Golang).
• Ability to read and understand C and/or C++, or a strong willingness and ability to develop these skills.
• Practical understanding of how network traffic is routed through modern networking systems.
• Strong knowledge of software engineering principles for production-grade systems and infrastructure.
• Experience troubleshooting complex systems, networking, or performance-related issues.
• Ability to work effectively with both high-level control-plane software and low-level systems or dataplane components.
• Strong analytical and debugging skills, with the ability to investigate issues across multiple layers of a networking stack.
• Understanding of virtual networking and modern cloud networking architectures is highly valuable.
• Experience with OVS, VPP, DPDK, Linux kernel networking subsystems, or comparable networking dataplanes is a strong advantage.
• Familiarity with network overlays, SDN, NFV, or DPI is beneficial.
• Knowledge of network protocols, routing, tunneling, and related networking technologies.
• Familiarity with BGP and MPLS is an advantage.
• Ability to understand complex technical architectures and contribute constructively to design decisions.

Responsabilités

• Develop and operate the Virtual Private Cloud (VPC) networking layer that provides reliable connectivity for cloud workloads.
• Design and implement scalable and resilient networking services for virtualized cloud environments.
• Develop and maintain the control plane, primarily using Go.
• Contribute to the development and integration of dataplane components, primarily written in C and based on open-source networking technologies.
• Improve the scalability, reliability, and operational stability of core cloud networking services.
• Develop networking functionality such as IPv6 support, service endpoints, VPC peering, and Layer 7 load balancing.
• Contribute to the development and improvement of network services including load balancers, firewalls, and security groups.
• Improve internal architecture and optimize interactions between VPC services and related cloud platform components.
• Investigate and resolve complex datapath and Linux kernel networking issues.
• Analyze and address networking performance bottlenecks at both system and application levels.
• Design and execute load and performance testing for cloud networking services.
• Debug complex issues involving routing, connectivity, concurrency, and distributed infrastructure.
• Develop reliable, high-performance, concurrent systems code suitable for large-scale production environments.
• Contribute to the resilience of cloud networking infrastructure so services remain operational during partial system or infrastructure failures.
• Collaborate with engineers working across control-plane, dataplane, networking, and platform infrastructure components.
• Participate in technical design discussions and contribute to improvements in the architecture of core networking services.
• Research and evaluate networking technologies and approaches that can improve platform capabilities and performance.
• Participate in coding interviews as part of the recruitment process.
