• Act as the primary technical point of contact with telecom operators and internal/external stakeholders, facilitating effective communication and collaboration.
• Ensure solutions comply with industry standards, regulatory requirements, legal frameworks (e.g., IPA 2016, GDPR), and security/compliance standards (e.g., ISO 27001, NIST, TSA).
• Provide technical leadership in solution integration, design reviews, documentation, and testing.
• Support operational teams with troubleshooting, performance optimisation, and knowledge sharing.
• Manage technical risks, issues, assumptions, dependencies, and all types of change throughout project lifecycles.
• Proactively identify and resolve delivery project issues (technical and non-technical).
• Contribute to continuous improvement and organisational knowledge sharing.

Required Skills and Experience:

• 5-10 years' experience working with telecommunications operators and delivering technical solutions in enterprise or service provider environments.
• Minimum 5 years' experience in writing and managing HLD/LLD documents for complex end-to-end IT and Telco solutions.
• Designing and integrating IT solutions (e.g., data repositories, middleware, workflow, CRM) with Telco networks and supporting technologies (OSS, BSS, IMS, NAT, CGNAT, IPv4/IPv6).
• Defining interface specifications (protocols, messages, formats).
• Leading teams and collaborating with multiple suppliers/third parties in a 'one-team' approach.

• Strong analytical, verbal, and written communication skills.
• Proven experience in software engineering and understanding of software development principles.
