Staff Software Engineer, Networking

Role Description

As a Staff Software Engineer in Networking, you will set the technical direction for the networking stack behind Docker's Sandboxes platform and make architectural decisions that ripple across Docker's product portfolio. Your work will directly enable Docker's expansion into AI and security products.

• Design, implement, and operate core networking services that power Docker's Sandboxes platform across local laptops and public cloud environments.
• Build scalable networking infrastructure for microVM orchestration, workload scheduling, and lifecycle management.
• Develop high-performance networking data- and control-plane components for multi-tenant agentic workloads.
• Ensure network reliability, observability, and performance across Docker's Sandbox infrastructure.
• Collaborate with product, platform, and security teams to deliver customer-focused capabilities.
• Participate in architectural discussions, code reviews, and design documents.
• Contribute to automation and CI/CD improvements across the deployment pipeline.
• Debug and resolve production issues across distributed systems in local and public-cloud environments.
• Take part in on-call rotation for your team; respond to incidents and drive continuous improvement of system reliability and availability.

Qualifications

• 8+ years of experience building and leading large-scale cloud or distributed systems, with a focus on networking foundations.
• Track record of driving technical consensus and delivering high-quality infrastructure software at scale, on tight timelines.
• Experience with microservices architecture, container networking, service mesh, policy enforcement, and container orchestration.
• Experience with kernel and user-space networking technologies, including Linux networking, OVS/OVN, DPDK, and eBPF.
• Experience designing and operating highly available, secure, and observable networking infrastructure.
• Strong understanding of cloud infrastructure (AWS, Azure, GCP, OCI) and related scalability patterns.
• Familiarity with CI/CD pipelines, monitoring, and infrastructure-as-code tooling.
• Excellent problem-solving and debugging skills in distributed environments.
• Strong communication skills and ability to collaborate across remote, cross-functional teams.
• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience.

Requirements

• First 30 days: Onboard, integrate with our Sandbox infrastructure teams, and build context on Docker's Sandbox vision.
• Deep-dive into Sandbox architecture for local and public-cloud infrastructure, with a focus on driving simple, common foundational primitives usable across both environments.
• Identify the highest-leverage opportunities in the current architecture, along with strategic and tactical execution risks.
• First 90 days: Develop a technical roadmap to address the challenges identified; drive consensus across stakeholders.
• Provide technical leadership to a small team of engineers to deliver on the roadmap.
• Establish or improve technical standards for development, deployment, operation, and observability of networking services.
• One-year outlook: Drive simplification of foundational networking infrastructure across local and public-cloud environments.
• Establish repeatable engineering practices for quality, performance, and operational excellence.
• Nurture the team's confidence and capability by providing clarity, sustaining focus, and delivering pragmatically through successive iteration.
• Set a standard for what a small team of engineers can deliver and manage when given a charter, autonomy, and the tools they need.
