I korthet

Network Development Engineers on the Capacity Restoration Team (CRT) are builders who create novel solutions for AWS's optical transport networks. This role involves troubleshooting and restoring out-of-service DWDM capacity, developing automation to accelerate restoration, and contributing to operational metrics and documentation. The position requires a Bachelor's degree or equivalent experience and at least 1+ years in optical network engineering or DWDM operations, with Python preferred for scripting.

Ansvarsområden

  • Troubleshoot and restore out-of-service optical capacity across DWDM backbone and metro networks, including coherent optics, amplifiers, ROADMs, and mux/demux components.
  • Diagnose optical impairments such as fiber attenuation, connector/splice loss, chromatic dispersion, PMD, OSNR degradation, and nonlinear effects.
  • Execute and interpret OTDR traces, optical spectrum analyzer (OSA) readings, and power meter measurements to isolate physical-layer faults.
  • Develop link test plans and structured diagnostic output for optical circuits.
  • Coordinate with fiber operations and vendor teams for fiber splicing, connector cleaning, and hardware RMA workflows.
  • Build and improve automation components for optical link and device restoration.
  • Extend and integrate with existing tooling for monitoring and alerting of out-of-service optical capacity.
  • Develop scripts to parse and correlate optical alarms from network management systems.
  • Write clean, testable Python code with documentation.
  • Create and maintain team-level operational metrics, monitors, and processes tied to CRT KPIs.
  • Contribute to optical network health dashboards tracking OSNR trends, amplifier performance, and span loss baselines.
  • Participate in on-call rotations for follow-the-sun coverage.
  • Document optical systems, tools, and runbooks clearly.

Krav

  • Bachelor's degree in Electrical Engineering, Photonics, Telecommunications, Computer Science, or equivalent experience.
  • 1+ years of experience in optical network engineering, DWDM operations, or optical transport systems.
  • Understanding of DWDM technology fundamentals: wavelength multiplexing, optical amplification (EDFA, Raman), coherent detection, and modulation formats.
  • Knowledge of fiber optic fundamentals: single-mode fiber types (G.652, G.654, G.655), attenuation, chromatic dispersion, and PMD.
  • Familiarity with optical test and measurement: OTDR, OSA, power meters, and light sources.
  • Experience with at least one programming or scripting language (Python preferred).
  • Understanding of IP networking fundamentals: TCP/IP, routing, and switching concepts.
  • Experience working in a Linux or Unix environment.
  • Ability to read, modify, and extend existing code within a shared codebase.

Önskade kvalifikationer

  • Experience with coherent optic technologies: DP-QPSK, 16QAM, and higher-order modulation formats at 100G/200G/400G+ line rates.
  • Experience with optical networking vendor platforms (e.g., Ciena, Infinera, Nokia, ADVA) including provisioning, alarm management, and firmware operations.
  • Knowledge of OSNR analysis, optical link budgets, and span engineering for long-haul and metro DWDM systems.
  • Understanding of FEC mechanisms (SD-FEC, HD-FEC) and their role in optical system margin management.
  • Experience with OTN framing, multiplexing hierarchy, and fault management.
  • Familiarity with ROADM architectures, CDC (Colorless/Directionless/Contentionless) designs, and wavelength switching.
  • Experience with network automation tools or frameworks such as Ansible, Terraform, or similar platforms applied to optical networks.
  • Exposure to Amazon internal tooling: workflow orchestration engines, optical network management systems, deployment automation tools, or link testing services.
  • Experience with optical network planning and modeling tools.
  • Knowledge of BGP or OSPF routing protocols in production network environments.
  • Experience operating large-scale optical networks in ISP, CDN, submarine, or cloud provider environments.
  • CCNA, JNCIA, or equivalent networking certification; vendor optical certifications (e.g., Ciena Certified Specialist) a plus.

Förmåner

  • Flexible work hours and arrangements
  • Inclusive culture with employee-led affinity groups
  • Ongoing events and learning experiences
  • Endless knowledge-sharing, mentorship, and career-advancing resources
