We are seeking a Senior Network Automation Architect — a software engineer first
, with deep domain expertise in network infrastructure.

This is not a traditional network engineering role with scripting
. This position owns the design, development, and delivery of production‑grade automation software that operates across a large‑scale, multi‑vendor network environment for a Managed Service Provider (MSP).

You will define the developer experience for the network organization: setting coding standards, designing extensible software architectures, building reusable Python libraries and internal platforms, implementing CI/CD pipelines, and mentoring engineers in modern software development practices.

You think in design patterns, clean abstractions, testability, and long‑term maintainability — and you apply that mindset to infrastructure automation.

• Architect and develop production-quality Python applications, libraries, and CLI tools for network automation, orchestration, and observability.
• Design clean, extensible architectures using patterns such as factory, strategy, adapter, and plugin-based systems to abstract vendor differences.
• Build and maintain API integrations (REST, Graph
  
  QL, gRPC, JSON‑RPC) with platforms including:
  • Arista Velo Cloud
• Develop internal Python packages with:
  • Semantic versioning
  • Internal PyPI distribution
  • Unit tests (pytest)
  • Integration tests
  • Network validation tests using mocks and fixtures
  • Shape Git strategies and repository structure.
• Leverage AI/LLM developer tooling responsibly to improve productivity and code quality.

• Author and maintain coding standards, architectural decision records (ADRs), and development guidelines
  .
• Establish and enforce code quality tooling:
  • PEP8
  • Black
  • My Py
• Design and implement CI/CD pipelines (Git Hub Actions, Git Lab CI, Jenkins) for:
  • Linting
  • Testing
  • Security scanning
  • Build and release automation
  • Branching strategies
  • Pull request standards
  • Release management
• Create project templates, scaffolding, and cookiecutters to standardize automation development.

• Identify manual workflows and operational pain points, then design automation solutions to eliminate them.
• Prototype new tools, frameworks, and approaches from idea through production adoption.
• Improve observability by integrating automation platforms with logging, monitoring, and alerting systems
  .
• Contribute to technology roadmap and vendor evaluation from a software architecture and productivity perspective.
• Mentor network engineers in:
  • Testing strategies
  • Code structure
  • Version control
• Lead code reviews with a teaching mindset
  .
• Facilitate workshops, knowledge-sharing sessions, and pair programming.
• Partner with Dev Ops, Cloud, Security, and Application teams to align engineering practices.

• 7+ years of professional software development experience with Python as the primary language.
• Advanced Python expertise:
  • Dataclasses / Pydantic
  • Experience building Python libraries, packages, and CLI tools (Click, Typer, argparse).
  • Strong testing background: pytest, mocking, fixtures, TDD.
  • Advanced Git skills (rebase, cherry‑pick, bisect, hooks).
  • Hands‑on experience designing and maintaining CI/CD pipelines.
  • Solid grounding in SOLID principles, design patterns, and clean architecture
    .
  • Experience writing technical documentation and developer guidelines.

• Strong understanding of:
  • Routing (BGP, OSPF)
  • Switching
  • VPNs and firewalls
  • N…
