## Job description

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 remote UK-based position places you at the core of Skylo's European partner ecosystem, driving the critical MNO relationships that define our presence in the region. You will collaborate onsite several days a week with a high-velocity, global team spanning multiple time zones. While London is our hub, we are open to remote arrangements for the right candidate located elsewhere in Europe.

## How You Will Impact Skylo

You will own end-to-end program delivery across the three systems that determine whether an MNO partner can be onboarded, whether traffic flows correctly, and whether it settles correctly: the packet core, the signalling plane, and billing & settlement. You sit at the seam between Network Engineering, Product, Solutions Engineering, Finance/Billing, and external partners (MNOs, IPX providers, clearing houses, roaming suppliers), and you are accountable for turning a growing partner pipeline into predictable, on-time technical delivery.

This is a builder's role. You will be defining the onboarding program, the release cadence, and the launch-readiness bar — not inheriting a mature machine.v

## What you'll do

- 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 signalling 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.

Sound like you? You bring: You know how wholesale roaming works end to end, and you have the program management discipline to keep a complex multi-partner portfolio running smoothly without losing track of the details.

- 8+ years in mobile core / signalling engineering or technical program leadership, with deep, hands-on time in the signalling plane
- Understanding of Signalling in 3GPP core, across EPC and 5GC:
- NAS procedures (attach, TAU, service request) and the interfaces that carry them — S6a, S6c, S13, SGd, T6a — with fluency in Diameter base protocol, AVP design, realm/application routing, and error/overload handling.
- DRA/DEA architecture: understanding of routing policy & topology
- A clear grasp of the SS7/MAP ↔ Diameter boundary and IWF interworking (e.g. legacy SMS via MAP over IPX vs. SGd Diameter).
- NB-IoT / CIoT and NTN signalling specifics: control-plane CIoT EPS optimisation, NIDD, and the way NTN propagation delay and timer handling (Rel-17 NTN) change attach/retransmission behaviour.
- Hands-on roaming operations: IREG/TADIG, IR.21/RAEX, IPX interconnect, and per-partner signalling readiness.
- Working understanding of billing & settlement as it depends on signalling and CDR generation: TAP3 (TD.57), RAP (TD.32), NRTRDE, and the CDR lifecycle from record generation to settlement.
- Demonstrated track record shipping cross-functional network programs on time across engineering and external partners.
- Credible in a signalling design review and in a partner integration call alike — equally at home with core engineers and external carrier counterparts.Every role at Skylo uses AI tools daily to amplify output. We expect active habits using AI tools and a track record of picking up new ones quickly.

It would be great if you had experience with:

- NTN, NB-IoT, or cellular IoT connectivity experience.
- SMS-over-NAS delivery paths (SGd Diameter and MAP-via-IPX), and CIoT optimizations (NIDD, control-plane CIoT).
- Experience with wholesale roaming, MVNO/MVNE, or roaming-hub environments.
- Familiarity with BCE and next-generation settlement, and with ERP/finance-system integration for billing.
- Exposure to clearing-house and IPX supplier commercial/technical management.

What Success Looks Like (First 6-12 Months)

- A single, trusted onboarding program that partner-facing and engineering teams both plan against — with cycle time trending down as volume grows.
- Signalling and billing readiness treated as a gated part of every partner launch, not a post-launch surprise.
- The multi-supplier roaming transition de-risked with a clear cutover and rollback plan, and no single-supplier lock-in surprises.
- Program-level visibility into signalling and settlement health that leadership actually uses to make calls.
