Employer immigration record

from this employer's Department of Labor filings

Files H-1B transfers

10 transfer filings in the last year, covering 10 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.

Sourced from Department of Labor LCA, PERM and prevailing-wage disclosure data. Employer matching is by name, so figures may be split across an employer's legal entities. Absence of a filing means none appears in our copy of the data, not that none exists.

About the role

  • Every MNO onboarding ends at a technical test gate.

Responsibilities

  • Own the IREG Testing Strategy: Define the roadmap for MNO onboarding-including clear pass/fail criteria, evidence requirements, and sign-off processes-so we can scale our roaming partnerships faster and more reliably.
  • Drive Testing Innovation: Look beyond manual execution to build a long-term automation strategy that makes our roaming validation smarter, faster, and eventually hands-free.
  • Build the Testing Lab: Design, scale, and maintain an automation harness capable of reliably running both standard GSMA and custom NB-IoT NTN scenarios.
  • Ensure End-to-End Interoperability: Validate the entire roaming journey (Registration, S6a/S6d, SGd, IP, NIDD), ensuring smooth handoffs across satellite and cellular networks.
  • Translate Complex Tech into Test Cases: Build comprehensive test scenarios by combining GSMA standards, partner network configurations, and our unique NB-IoT NTN traffic profiles.
  • Own the Defect Lifecycle: Don't just log bugs-track them down to the root cause, partner with engineering on the fix, and see them through to complete closure.
  • Keep Leadership Informed: Build and share clear dashboards covering test cycle times, defect rates, and overall readiness so the business always knows where MNO onboarding stands.

Requirements

  • 5+ years of experience in roaming, mobile core, interconnect, IREG, or telecommunications network testing.
  • Experience reading Wireshark or equivalent signalling traces and diagnosing network failures involving multiple parties.
  • Experience designing automated telecommunications testing frameworks using Python or comparable languages and CI practices.

Nice to have

  • NB-IoT, NTN, NIDD, IoT roaming, GSMA test-suite, or device-lab experience.
  • Familiarity with IMSI Tracing, Diameter/SS7 testing tools, Jira, Confluence, and dashboarding.
  • Experience integrating network testing with TAP and billing validation.
  • 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
  • Open, transparent, inclusive culture that blends Silicon Valley, Nordic, and South Asia characteristics.

Skills

  • The world still has coverage blind spots.
  • Skylo has pioneered a standards-based approach to satellite connectivity.
  • No special hardware, no entirely new networks.
  • Just billions of existing devices, suddenly reachable anywhere on Earth.
  • 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.
  • 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 hybrid in Mountain View, CA
