As a global specialty telecommunications provider, 1GLOBAL serves financial institutions, enterprises, mobile network operators, and consumers across 42 countries, offering fully regulated voice, data, and SMS services. As pioneers in the eSIM revolution, we have built a complete ecosystem that drives our growth with partners such as Apple, Palo Alto Networks and Google, while attracting customers like Goldman Sachs, JP Morgan, Revolut, Netflix and Tesla.

  • Identify areas of improvement in the codebase and promote them through seamless integrations, documenting solutions, and new flows;
  • Mentor junior members when needed and contribute with meaningful reviews.

Requirements:

  • Experience in Java software development;
  • Experience with unit/integration/e2e testing (test-driven development is a plus);
  • Proficiency with REST APIs, both in implementing and consuming interfaces;
  • Experience with development tools and processes (Git-flow, peer reviewing);
  • Familiarity with relational databases, CI/CD flows, Git, Docker, and Kubernetes;
  • Good understanding of cloud services and scalable infrastructure;
  • Excellent communication skills (fluent in English, both written and spoken), with a self-motivated and autonomous mindset.

Salary: $120,000 - $180,000 per year (estimated)

Growth Opportunities: Advance your career in one of the fastest-growing telecommunications companies, expanding over 40% year-on-year under the leadership of successful tech entrepreneurs.

Major Transaction Exposure: Be in the driver’s seat for transactions that will have an impact on the future telco industry.

Work with a Talented Team: From the Board and the Founders to the Senior Management Team, you will collaborate daily with the most capable and renowned external advisors, and constantly be exposed to talented and driven individuals.

Dynamic Work Environment: Thrive in a collaborative, fast-paced workplace where innovation is encouraged, and every contribution counts.

Professional Development: Work alongside industry experts to enhance your skills and knowledge in a cutting-edge field.

International Experience: Gain opportunities to work in different 1GLOBAL offices around the world as you grow within the company.
