About the role

Orion Innovation is a premier, award-winning, global business and technology services firm.  Orion delivers game-changing business transformation and product development rooted in digital strategy, experience design, and engineering, with a unique combination of agility, scale, and maturity.  We work with a wide range of clients across many industries including financial services, professional services, telecommunications and media, consumer products, automotive, industrial automation, professional sports and entertainment, life sciences, ecommerce, and education.

Our Partner

Our partner (listed on NASDAQ) is the leading expert in 5G ready cloud-native, network intelligence solutions for telecom operators transitioning to 5G. Their Network Intelligence consists of Network Visibility, Service Assurance, and Network Insights. The Network Intelligence suite offers intelligent, container-based, on-demand solutions to deliver network analysis from the RAN to the Core for 5G assurance. Utilizing automated and dynamic solutions with smart minimal data collection and on-demand troubleshooting and cutting-edge techniques based on machine learning, these solutions work in harmony to provide operators an understanding of the entire customer experience and allow them to troubleshoot network performance from a high to granular level while reducing storage costs and cloud resource utilization.

Overall Objective of the Role

We are looking for a Senior Backend Developer to join us in building a new generation of backend microservices that combine telecom-grade robustness with the power of AI. You’ll develop high-performance systems while integrating and orchestrating Large Language Models (LLMs) directly into backend flows – not just consuming APIs, but shaping how AI enhances network data processing, automation, and reasoning. This is a hands-on role where you’ll be working in a small, agile team with strong AI and telecom collaboration. Our goal is to bring together structured data, intelligent backend design, and state-of-the-art AI models to solve real-world problems in telecom. You’ll also work with telecom-specific AI components such as the RAN Intelligent Controller (RIC) – a critical part of 5G network automation. 

Responsibilities

  • Design and develop backend microservices using: Python and Go (and possible latter Java/Spring Boot).
  • Create services that embed and interact with LLMs (e.g., prompt pipelines, output parsing, feedback loops).
  • Contribute to the architecture of hybrid AI + telecom systems.
  • Build scalable APIs and efficient pipelines to process telco/networking data and expose them through API Gateways.
  • Package and deploy services with Docker & Kubernetes.
  • Collaborate closely with AI engineers and telecom domain experts in a fast-paced, agile team.

Requirements

Must Have:

  • BSc in Computer Science, Engineering or similar technical degree.
  • 4+ years of backend development experience using Python.
  • Solid understanding of microservices architectures and API-based systems.
  • Hands-on experience with Docker, Kubernetes, and CI/CD pipelines.
  • Familiarity with CI/CD workflows and Linux environments.
  • Understanding of SQL and relational databases.
  • Passion for AI and some practical exposure to LLMs (OpenAI, Hugging Face, LangChain, etc.) even in hobby/personal projects.
  • Willingness to learn telecom concepts like 4G/5G, RAN, Core.

Nice to Have:

  • Experience with Java is preferred.
  • Experience with Go is nice, but not by itself only.
  • Understanding of telecom networks, 5G architecture, or network automation.
  • Experience building orchestration logic or wrapper services for LLMs.
  • Familiarity with embedding/vector databases (e.g., Pinecone, Weaviate, Qdrant).
  • Familiarity with API Gateways and request-routing logic.

Reasons to Work with Us

  • Competitive financial conditions.
  • Opportunity to work on internationally recognized projects.
  • Flexible schedule and a hybrid work model, prioritizing remote work as much as possible to support work-life balance.
  • An exciting career path within a friendly, dynamic, and growing organization.
  • Professional development opportunities in a multicultural environment. 
  • Private medical coverage with Medlife or Regina Maria.
  • Meal vouchers.
  • Gift vouchers for special occasions such as birthdays, weddings, o
