I korthet

Amazon Web Services (AWS) is hiring an Optical Network Development Engineer for its Capacity Restoration Team (CRT) in Hyderabad, India. This role involves troubleshooting and restoring DWDM optical capacity, building automation for faster restoration, and improving network health monitoring. The ideal candidate has experience in optical network engineering, DWDM operations, and scripting with Python, bridging optical operations and engineering to drive efficiency and cost-effectiveness.

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: 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 that accelerate optical link and device restoration.
  • Extend and integrate with existing tooling to improve monitoring and alerting for out-of-service optical capacity.
  • Develop scripts to parse and correlate optical alarms from network management systems and identify systemic patterns.
  • Write clean, testable code (Python preferred) 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 and follow-the-sun coverage.
  • Document optical systems, tools, and runbooks clearly.
  • Contribute to design reviews and operational improvement discussions.
  • Actively learn team product architecture — both optical transport and IP layers — and apply that knowledge to deliver working solutions.

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 are part of our culture.
  • Inclusive culture that welcomes bold ideas and empowers you to own them to completion.
  • Endless knowledge-sharing, mentorship and other career-advancing resources.
