Job summary

Skylo Technologies in the United States is seeking a senior program leader to own end-to-end technical delivery across MNO onboarding, core signalling, and billing systems. You will bridge network engineering, product, and finance to turn a growing partner pipeline into predictable launches.

You will define onboarding programs, release cadences, and readiness standards from the ground up, ensuring seamless traffic flow and accurate financial settlement. This role is remote in the U.S.

Qualifications

• 8+ years of experience in mobile core/signaling engineering or technical program leadership.
• Deep knowledge of end-to-end wholesale roaming operations, including IREG/TADIG, IR.21/RAEX, and IPX interconnect.
• Comprehensive understanding of 3GPP core signaling (EPC and 5GC), NAS procedures, Diameter base protocol, and DRA routing architecture.
• Clear structural grasp of the SS7/MAP to Diameter boundary, IWF interworking, and the overall CDR billing lifecycle (TAP3, RAP, NRTRDE).
• Demonstrated success leading ambiguous network initiatives and shipping cross-functional programs on time with external carrier counterparts.
• Strong communication skills, with equal credibility inside a technical signaling design review or on a commercial partner call.

Responsibilities

• Own the MNO technical onboarding program end-to-end from the core/signalling/billing lens — integration milestones, dependencies, Definitions of Done, and cutover plans across the partner lifecycle.
• Drive signaling delivery programs: Diameter interfaces (S6a, SGd), MAP-over-IPX via IWF, DRA configuration and routing policy, SMS-over-NAS enablement, and roaming signalling readiness per partner.
• Coordinate billing & settlement programs: TAP3 / RAP / NRTRDE exchange, BCE readiness, mediation and rating, CDR integrity and reconciliation, and integration with settlement and finance systems.
• Program-manage the multi-supplier roaming stack — supplier onboarding, contractual/technical cutover, parallel-run and rollback planning, and de-risking the transition away from single-supplier dependency.
• Run program governance: maintain roadmaps, RAID logs, release trains, and cross-functional launch-readiness reviews; make dependencies and risks visible before they become escalations.
• Own the metrics that matter: onboarding cycle time, signalling success/attach rates, routing correctness, CDR and settlement accuracy, and billing-run reliability — and report them to engineering and commercial leadership.
• Be the translation layer between deep network engineering and commercial/partner stakeholders, so that partner commitments and network reality stay aligned.
