Technical Program Manager - Core Network Delivery & MNO Onboarding

The world still has coverage blind spots. You could help eliminate them at Skylo.

Skylo has pioneered a standards-based approach to satellite connectivity. We connect smartphones and IoT devices directly to satellites. No special hardware, no entirely new networks. Just billions of existing devices, suddenly reachable anywhere on Earth. We're not building toward this future. We're already in it.

Our direct-to-device service is live on millions of activated devices across five continents, covering more than 72 million square kilometers, in partnership with leading satellite operators, mobile network operators, Tier-1 chipset makers, and OEMs worldwide. And we're just getting started.

At the heart of it all is Skylo's commercial NTN vRAN: a 3GPP standards-based, cloud-native platform that seamlessly bridges terrestrial and satellite networks. It's the infrastructure that makes true anywhere, anytime connectivity possible.

When you join Skylo, you'll work at the intersection of three markets reshaping how the world stays connected: mass-market consumer devices, automotive, and industrial IoT. Enabling people outdoors and critical workflows in the world's most remote places.

This is a rare chance to work on technology that matters, at a company that's already proving it works

This role is fully remote in the U.S

ABOUT THE ROLE

We are hiring a senior program leader to own end-to-end technical delivery across packet core, signalling, and billing systems for MNO partner onboarding. This role sits at the intersection of Network Engineering, Product, Solutions Engineering, and Finance, converting a growing partner pipeline into predictable, on-time launches. You will build and define the onboarding program, release cadence, and launch-readiness standards from the ground up to ensure seamless traffic flow and correct financial settlement.

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.
• REQUIRED QUALIFICATIONS
• 8+ years of experience in mobile core/signaling engineering or technical program leadership with hands-on time in the signaling plane.
• 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/DEA 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.

PREFERRED QUALIFICATIONS

• Experience with NTN (Non-Terrestrial Networks), NB-IoT, or cellular IoT connectivity, including Rel-17 NTN propagation delay and timer handling.
• Familiarity with control-plane CIoT EPS optimization, NIDD, SMS-over-NAS delivery paths, and roaming-hub environments.
• Experience with BCE (Billing and Charging Evolution), next-generation settlement, and ERP/finance-system integration.
• Exposure to commercial and technical management of clearing-houses and IPX suppliers
• Track record of rapidly learning and integrating new AI productivity tools into daily engineering workflows.

WHAT WE OFFER

• Competitive compensation packages including a stock option-based equity program
• Comprehensive benefits including medical, dental, vision, and retirement plan
• Monthly allowances for wellness and education reimbursement
• A generous time-off policy, holidays, and the opportunity to temporarily work abroad
• A once-in-a-career opportunity to operate the world's first commercial, live direct-to-device satellite network
• Access to a world-class team across software, hardware, chipsets, telecom, satellite, and network virtualization
• The estimated base salary range for this role is
• $130,000 — $145,000

. Within the range, individual pay is determined by work location and additional factors, including job-related skills, experience, and relevant training.

In addition to base salary, Skylo offers a competitive benefits package including health insurance, retirement plans, paid time off, and equity options.
