We're seeking a senior architect to assist with design of command and control plane applications that activate and manage CPEs in our DOCSIS/Fiber network. The ideal candidate will have a strong background in software development, experience with DOCSIS technology, and deep knowledge of control plane protocols (DHCP, TFTP, TR-069) used for device activation and CPE lifecycle management.
Key Responsibilities:
- Design command & control plane software for DOCSIS/Fiber systems, including DHCP provisioning, TFTP configuration delivery, TR-069/TR-369 device management, and firmware upgrade orchestration.
- Integrate control plane services with DOCSIS systems, including CMTS/OLT and cable modem configurations (DOCSIS/DPoE).
- Develop APIs and interfaces for control plane systems and operational dashboards, including RESTful APIs and SOAP-based interfaces.
- Design and develop API layers to front-end DHCP, datastore, and TFTP applications across multiple footprints, enabling unified access and management.
- Design and implement workflow orchestration for device activation and management processes using BPMN or similar workflow engines.
- Troubleshoot and Debug: Troubleshoot and debug control plane software issues across DHCP, TFTP, and TR-069 workflows, including providing solutions to resolve defects and optimizing performance.
- Collaborate with Cross-Functional Teams: Collaborate with cross-functional teams, including network operations, engineering, and product management, to ensure control plane systems meet business requirements.
Requirements:
- Experience: 8+ years of software development experience with at least 5 years working on network management or device provisioning systems.
- Programming Languages: Proficiency in programming languages, such as Java, Python, RUST or C/C++.
- DOCSIS Technology: 3+ years of experience with DOCSIS technology, including CMTS and cable modem configurations.
- Network Management Protocols: Deep knowledge of control plane protocols, including DHCP, TFTP, SNMP, TR-069/TR-369 (CWMP/USP). Preferably, must have worked on DHCP/TFTP applications.
- IPv6 Knowledge: Strong understanding of IPv6 addressing, DHCPv6, and dual-stack implementations in cable networks.
- API Development: Strong proficiency in API design and development (REST, SOAP) with experience building API layers for multi-footprint systems.
- Workflow Development: Experience with workflow orchestration and BPMN (Business Process Model and Notation) or similar workflow engines.
- Software Development: Experience with software development methodologies, including Agile and Scrum.
- Strong Analytical Skills: Strong analytical skills and attention to detail.
- CPE Management: Proven experience designing and implementing CPE provisioning, activation, and firmware management systems.
- Experience with CI/CD pipelines and DevOps practices (GitLab CI, Docker, Kubernetes).
