Job description

Andersen is hiring a Solutions Architect for a telecom project in Kazakhstan. The role focuses on supporting BSS system transformation and vendor selection to improve business processes and IT systems. 

 

The customer is a prominent player in the telecommunications industry, distinguished by its commitment to innovation, customer experience, and employee development. As a pioneer in launching cutting-edge technologies like 5G in Kazakhstan, the customer continuously invests in network quality and digital transformation.

The project is focused on supporting the client in the strategic transformation of its BSS system, including the preparation and execution of a full-cycle RFP process to select a new vendor. The goal is to enhance business flexibility, optimize operational processes, and modernize the IT landscape through a structured and expert-driven vendor selection approach. 

 

Responsibilities: 

  • Analyzing the client’s current architecture (“As-Is”), studying documentation, and collecting data on integration links and dependencies. 

  • Identifying architectural risks and technical limitations. 

  • Mapping business needs against target requirements (ToR), participating in the development and refinement of requirements, and validating their completeness and feasibility. 

  • Evaluating vendor architectural solutions, analyzing RFP descriptions, assessing flexibility, scalability, compatibility, and identifying potential conflicts or mismatches. 

  • Performing GAP analysis of architectural components, creating GAP tables, and comparing vendor solutions by architectural parameters. 

  • Conducting GAP analysis of finalists, building GAP matrices, and justifying required modifications and their impact on TTM (time to market). 

  • Assessing TCO and licensing, analyzing CAPEX/OPEX impact, and verifying ownership cost calculations (clustering, redundancy, etc.). 

  • Preparing architectural recommendations, contributing to the final assessment, and documenting risks and assumptions. 

  • Updating ToR and GAP “As-Is,” defining requirements for architecture, integrations, and SLA, and drafting architectural sections of ToR. 

  • Preparing final architecture sections for reports and presentations. 

 

Must-haves: 

  • Experience as a Solutions Architect in BSS implementation or transformation projects for 5+ years. 

  • Experience in analyzing “as-is” and designing “to-be” architectures. 

  • Experience in documenting integration scenarios (ESB, API, batch). 

  • Experience in assessing architectural risks and technical feasibility of solutions. 

  • Participation in RFP processes and vendor architecture evaluations. 

  • Knowledge of architectural frameworks (TOGAF, eTOM, SID — will be a plus). 

  • Proven expertise in subsystems such as Billing, CRM, Order Management and Provisioning, Product Catalog, and Integration Layer (SOA, ESB, REST/SOAP, file exchange, Kafka). 

  • Experience with vendor solutions: Amdocs, Netcracker, Huawei CBS, Ericsson BSCS, BriteBill, CSG (at least some of them). 

  • Experience working in multi-vendor environments, participating in RFP evaluations, technical due diligence, and billing migrations. 

  • Level of English – Intermediate+ and above.
