1GLOBAL is a leading telecommunications company dedicated to creating better connections between people, devices, and businesses through innovative mobile solutions. Based in the UK, the company specializes in eSIM technology, internet telephony, and global communication services. By investing significantly in its infrastructure, 1GLOBAL aims to revolutionize connectivity on a global scale, enabling seamless interactions across international enterprises, IoT device makers, and telecommunications operators. Through its unique offerings, 1GLOBAL connects billions of individuals and devices, fostering a world where communication is improved and more efficient.

📋 Description

• Design and build 1GLOBAL’s internal AI platform: RAG pipelines, vector search infrastructure, and conversational interfaces. • Evaluate, integrate, and operate large language models (open-source and cloud-hosted) in production, balancing accuracy, latency, and cost. • Build secure ingestion and indexing pipelines for internal knowledge sources (Confluence, SharePoint, document repositories, internal APIs) with appropriate access controls. • Develop backend services and APIs that expose AI capabilities to internal users and, over time, to product teams building customer-facing features. • Establish engineering standards for the AI function: testing, deployment, monitoring, and model evaluation frameworks. • Own the full development lifecycle from requirements through production monitoring, with a bias toward shipping and iterating.

🎯 Requirements

• 5+ years of software engineering experience, with at least 2 years focused on AI/ML systems in production. • Hands-on experience building RAG pipelines, working with vector databases (Pinecone, Weaviate, Elasticsearch, or similar), and integrating LLMs into backend services. • Strong backend engineering skills: API design, microservices, production operations at scale. Proficiency in Python expected. • Practical experience with LLM fine-tuning, prompt engineering, and evaluation methodologies. • Comfortable with CI/CD, containerization (Docker, Kubernetes), and infrastructure-as-code. • Familiarity with data security practices (PII handling, access controls, data classification). Experience in regulated environments (financial services, telecommunications, ISO 27001) is an advantage. • Telecommunications domain knowledge is a plus but not required. • Strong communicator who can explain technical trade-offs to non-technical stakeholders. Fluent in English. • Self-directed and comfortable with ambiguity. You will be shaping the function, not joining a mature one.

🏖️ Benefits

• Growth Opportunities: Advance your career in one of the fastest growing telecommunications companies, expanding over 100% 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 being 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. • Open Communication Culture: Join a team where your ideas are heard, and open dialogue is encouraged, fostering a supportive and transparent work environment. • Get Things Done Attitude: Be part of a results-driven team that values efficiency, creativity, and the drive to make a tangible impact in the industry.
