Tx Network Product Manager (Optical Transport Presales)

About the role

This is a hands-on technical presales position for someone who knows optical transport networks inside out. You will work directly with Tier-1 mobile operator engineering leads and CTO offices in Zambia, helping them shape high-capacity DWDM, OTN and IP backhaul roadmaps. The role turns complex fiber transport requirements into commercial network designs, builds Bills of Materials (BOMs) and defends technical architectures during operator tenders.

Key responsibilities

• Own the technical presales cycle for optical transmission (DWDM, OTN, SDH) and IP transport networks across major telecom operators and high-capacity enterprise clients in Zambia.
• Lead the end-to-end technical response for major operator RFXs, including fiber link budgeting, network dimensioning, BOM creation and solution pricing strategy.
• Run technical workshops, product deep-dives and proof-of-concept (PoC) trials with operator network planning and engineering teams.
• Analyze client network bottlenecks to spot expansion and modernization opportunities before tenders are launched.
• Monitor competing optical transport vendors so the company's architectures keep a distinct technical and commercial edge.

Required profile

• Bachelor's degree in Telecommunications Engineering, Electrical Engineering or Computer Science.
• More than 5 years of experience in presales, network architecture or product management focused on optical transmission networks (DWDM, OTN, WDM, SDH) and IP transport.
• Direct experience running technical bid defenses and operator tenders in the Zambia telecom market.
• Clear, authoritative presentation skills that bridge deep engineering detail and commercial outcomes.
• Open to locals only.

Required skills

• Solid grasp of optical transport protocols, ROADM architectures and link budgeting.
• Metro backhaul and high-speed fiber network topology design.
