Staff Software Engineer – Network Automation

The role

You will build and shape the next generation of network automation platforms. This involves creating API-driven, declarative software and control-plane services to manage global production infrastructure.

What you will do

• Provide technical leadership and architectural direction for network automation and infrastructure control platforms.
• Use domain-driven design to establish shared language and versioned, testable contracts.
• Design and build APIs, services, controllers and reconciliation workflows.
• Build on the Kubernetes API, including custom resources and control loops.
• Own the operational Kubernetes path including CRD rollout, RBAC, and deployment drift.
• Design distributed workflows that operate under eventual consistency and partial failure.
• Design stable APIs, schemas and data models including versioning.
• Develop patterns for multi-tenant infrastructure platforms.
• Establish approaches to testing, observability and change safety.
• Improve software delivery practices through automated CI gates and deployment strategies.

Required qualifications

• Deep expertise in a backend language such as Python, Go, Rust or Java, including asynchronous concurrency, static typing, data modelling and validation, API development, packaging and tooling.
• Strong experience building Kubernetes controllers or operators, including custom resources and reconciliation/control-loop patterns.
• Strong experience building event-driven distributed systems, particularly eventual consistency, at-least-once delivery, idempotency, optimistic concurrency and partial-failure handling.
• Experience designing and building self-service, multi-tenant platforms, including tenant isolation, policy and access control.
• Strong API and schema design skills, including versioning and schema evolution for interfaces consumed by other teams and systems.
• Demonstrated technical leadership across team boundaries, including driving architectural designs, building agreement among senior technical stakeholders and mentoring other engineers.
• A track record of taking ambiguous, technically complex problems from architecture through to reliable production systems that manage large-scale infrastructure, such as networks, compute or cloud res

Nice to have

• Networking fundamentals, particularly BGP, IP fabrics and VXLAN/EVPN/L3VPN.
• Working knowledge of Go, sufficient to understand and contribute to adjacent services and controllers.
• Experience designing testing and observability strategies for production infrastructure automation.
• Experience with graph databases, or with source-of-truth systems that model infrastructure and its relationships.
