- Drive modular OS architecture best practices, including service decomposition, isolation, failure domains, and dependency management.
- Demonstrate deep knowledge of Network OS internals across control plane, data plane, and management plane, including IPC mechanisms, APIs, service contracts, and shared‑state management.
- Design and evaluate distributed systems with strict availability, scalability, and performance requirements.
- Architect and assess VM‑based and containerized solutions supporting control‑plane, management‑plane, and platform services.
- Guide observability and telemetry strategies, including metrics, logging, tracing, and system introspection in large‑scale software systems.
- Define and influence software upgrade, downgrade, rollback, and fallback mechanisms, including hitless or near‑hitless approaches.
- Analyze upgrade impact across IPC mechanisms, APIs, persistent state, and databases.
- Analyze complex system behavior under failure, scale, and upgrade scenarios.
- Identify architectural limitations in routing, switching, and security systems and define technically sound workarounds.
- Provide deep technical leadership across routing and MPLS technologies, including:
- IPv4 / IPv6
- OSPF, IS‑IS, BGP
- RSVP, LDP (FRR), QoS, Multicast
- BGP‑LS, PCEP, Segment Routing
- Service architectures including L2VPN, L3VPN, and EVPN
- Partner closely with Product Management and Development to define new products and contribute to Ribbon’s long‑term architectural vision.
- Develop value propositions and solution architectures leveraging Ribbon and third‑party technologies to meet customer requirements.
- Identify and develop business opportunities for IP and Optical solutions within the Service Provider market.
- Support business success through high‑quality RFI, RFP, and RFQ responses.
- Deliver technical training and knowledge transfer to customers, internal sales teams, and Ribbon Architects and Systems Engineers.
- Contribute to go‑to‑market strategies for assigned product lines.
- Coordinate and lead customer lab trials and proofs of concept in collaboration with cross‑functional teams.
- Conduct ongoing technical presentations within targeted accounts to uncover future opportunities and strengthen customer relationships.
- Bachelor’s or Master’s degree in Engineering, Computer Science, or a related technical field (Master’s preferred).
- Proven experience in software architecture within the telecommunications or networking industry, including successful engagement with Tier 1 and Tier 2 Service Providers.
- Pre‑sales or customer‑facing L1–L3 network engineering experience, with a strong telecommunications focus.
- Strong technical background in:
- IP/MPLS, MPLS‑TP, Carrier Ethernet
- IP routing and signaling protocols
- Mobile networks (4G, 5G)
- Demonstrated experience in customer‑facing technical engagements.
- Juniper and/or Cisco experience and certifications preferred.
- In‑depth knowledge of communications and networking standards, architectures, and industry best practices.
- Proven ability to build strong relationships with customers at all organizational levels.
- Excellent written and verbal communication and presentation skills.

What you need to know about the Los Angeles Tech Scene
Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.
Key Facts About Los Angeles Tech
- Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
- Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
- Key Industries: Artificial intelligence, adtech, media, software, game development
- Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
