About the Job

Requirements

  • Strong English communication skills to explain complex ideas and collaborate across global teams.
  • Perseverance in designing robust solutions for complex, evolving external systems and navigating dynamic behaviors through systematic debugging and experimentation.
  • Ability to collaborate effectively with diverse teams and stakeholders across large organizational structures and understand the business context behind commercial offerings.

About the Company

Gigs

Global eSIM and SIM integration platform

Gigs provides seamless connectivity integration for platforms, devices, and eCommerce, offering eSIM and SIM options that can be embedded into a client’s existing systems to enable global internet subscriptions, top-ups, and secure connections in 200+ countries. Clients manage offerings through a fully digital platform that supports payments, identity verification, and self-management, allowing two-minute sign-up without becoming a connectivity provider. The company differentiates itself by prioritizing integration-first connectivity rather than building its own network, focusing on rapid go-to-market, end-to-end platform management, and favorable margins for partners. Its goal is to help partners expand global reach, boost conversion rates and subscription revenue, and reduce product returns by delivering easy-to-integrate, worldwide connectivity.
