Key responsibilities:

Architecture Roadmap (15%):

  • Contribute to the development and execution of the HFC and DAA architecture roadmap.
  • Evaluate new technologies (e.g., DOCSIS 4.0, R-PHY, virtual CCAP) to enhance telco network performance and customer experience.
  • Align architecture strategies with business goals and emerging industry standards.

Architecture Delivery (60%)

  • Lead the design and deployment of high-impact HFC access network solutions in a telco environment.
  • Ensure architecture aligns with enterprise standards, policy, and regulatory requirements.
  • Manage architecture risks, dependencies, and integration challenges.
  • Support validation, testing, and transition to operational teams for smooth rollout.

Stakeholder Management (25%)

  • Provide technical oversight and guidance to engineering and delivery teams.
  • Work with vendors and internal teams on equipment specification, configuration, and deployment.
  • Engage with CTO stakeholders to identify and adopt relevant technologies.

Knowledge & skills required:

  • 8+ years of experience in HFC or DOCSIS-based access network architecture within a telco or broadband operator setting.
  • Strong knowledge of DOCSIS 3.0/3.1/4.0 PHY & MAC (QAM, OFDM, bonding, QoS, BPI+).
  • Experience in HFC plant design (nodes, amplifiers, taps, ingress/egress control, PNM)
  • Proficiency in CMTS/CCAP configuration, service flows, and IP provisioning (IPv4/IPv6).
  • Familiarity with R-PHY protocols (R-DEPI, R-UEPI, GCP) and RPD lifecycle management.
  • CIN/IP/MPLS network design experience, including QoS and latency/jitter management in telecommunications networks.
  • Understanding of timing/sync protocols: IEEE 1588v2 PTP, SyncE.
  • Experience with security frameworks (MACsec, IPsec, TLS, RADSEC, X.509 PKI)
  • Knowledge of virtual CCAP architecture, including containerized deployments.
  • Exposure to OSS/BSS integration (DHCP, RADIUS, NetConf/YANG, TFTP)
  • Skilled in automation and scripting (Python, Ansible), telemetry (SNMP, Kafka, gRPC).
  • Packet-level troubleshooting using Wireshark for DOCSIS and R-PHY protocols.
  • Familiarity with standards from CableLabs, SCTE, IETF.
  • Strong cross-disciplinary understanding of RF engineering and IP networking
  • Excellent communication and stakeholder engagement skills
