Responsibilities

• Work closely with business stakeholders, delivery managers, and other teams to translate business requirements into DLT-based technical solutions. Ensure that the architectural vision aligns with business objectives and user needs.

• Serve as a technical authority on DLT during the presales process, advising clients on platform selection (public vs. private vs. permissioned networks), privacy models, interoperability, and the business impact of these choices. Answer technical questions and concerns raised by clients, helping to build trust and confidence in the proposed solution.

• Collaborate with sales and project management teams to develop detailed proposals that include technical specifications, project timelines, and cost estimates. Ensure the proposed architecture is feasible, scalable, and meets the client’s expectations.

• Identify opportunities to combine DLT solutions with AI capabilities (e.g., LLM-based automation, analytics, compliance monitoring) to add value to client platforms.
