Podsumowanie oferty

Build a cloud-native network orchestration platform for tier-1 ISP router networks, implementing service-design specifications across the service lifecycle. The role focuses on backend systems using Python, Kubernetes, and network technologies including BGP, IS-IS, and MPLS.

Wymagania

Required qualifications:

Hands-on experience with service-provider networking, including BGP, IS-IS, MPLS L2/L3 VPNs, IP routing, and addressing/IPAM concepts.
Strong Python skills, including production-quality code, clear APIs, structured error handling, and tests; at least 3 years in a production codebase.
Ability to turn design specifications into code and provide feedback on specifications.
Working proficiency with Kubernetes and cloud environments (Azure or AWS), including deploying, running, and troubleshooting services in a Kubernetes cluster.
Ability to correlate events and logs across distributed systems to find root causes.
Application-development experience with SQL databases, including migrations, schemas, and transactions.
Fluent English.

Nice to have:

Hands-on experience with a workflow-orchestration engine.
Experience owning features end-to-end, including rollback and recovery paths.
Familiarity with service-provider router platforms, including Cisco, DriveNets/DNOS, Juniper, Nokia, or Arista.
Exposure to NETCONF/YANG or gNMI/OpenConfig.
Experience instrumenting services with Prometheus/Grafana or equivalent observability tools.
Comfort using Linux, Docker, and virtualised environments.
Experience with CI/CD pipelines and multi-repository release engineering.
Experience operating an AI-assisted development pipeline involving agent-driven code review, LLM-drafted specifications, and orchestrated ticket flows.

Obowiązki

Translate provisioning blueprints and service-design specifications into Python plan generators that produce device configuration and service-related artifacts.
Clarify specification details with System Architects and update the specifications and code together.
Model service-lifecycle behaviour for IP-Link, BGP, IS-IS, and sys-config service graphs, including create-versus-adopt semantics, idempotency, and undo.
Design Temporal-based workflows and custom Python tasks that execute plans and handle partial failures safely.
Contribute to reference-data alignment, configuration-template generation, and workflow YAML authoring.
Integrate with platform systems, including inventory, IPAM, resource management, and service catalogues, and with router interfaces via NETCONF, gNMI, REST, and CLI.
Deliver changes across multiple repositories and long-lived release branches, including porting fixes between branches.
Add observability through metrics, structured logs, and workflow-instance traces.
Write and maintain tests using pytest and golden fixtures, maintain type-check-clean code, and contribute to end-to-end scenarios where relevant.
Use the AI-native development pipeline as the daily working model.
