About the role Route Mobile is seeking a customer-facing Presales professional with strong, proven experience in cloud communications (CPaaS) and AI-led customer engagement.

Coordinate with Product, Heltar specialists, Engineering, Security, Operations, Commercial and Legal to validate feasibility, product gaps, compliance and commercial assumptions. Build reusable demo stories, reference architectures and industry use cases; contribute customer insights and competitive intelligence to GTM and product roadmaps.

Must-have experience and capabilities 5–9 years preferred in enterprise Presales / Solution Engineering within CPaaS, cloud communications, messaging, conversational AI or a closely related provider ecosystem; strong preference for candidates from BSPs, CPaaS vendors, messaging aggregators or customer-engagement platforms.

Hands-on exposure to AI chatbot/agent solutions, LLM-enabled workflows, prompt and knowledge-base design concepts, retrieval-augmented generation (RAG) fundamentals, guardrails and human escalation. Strong REST API, JSON, webhook, OAuth/authentication, Postman and cloud-integration skills; ability to interpret logs, test endpoints and troubleshoot POC issues. Experience with enterprise CRM, contact-center, marketing automation or banking/commerce systems; confident discussing integration patterns and data/security considerations.
