Pre-Sales Engineer

About Open Open is building an AI-native customer experience platform that helps companies automate and manage customer communication across chat, email, WhatsApp, and voice. Our customers include fast-growing technology companies and global enterprises across fintech, commerce, logistics, travel, and other industries. We are looking for a strong Pre-Sales Engineer who can work closely with our commercial team and prospective customers to turn complex requirements into clear, technically credible solutions. The Role As a Pre-Sales Engineer at Open, you will sit between Sales, Product, Engineering, and the customer. Your job is to deeply understand a prospect's technical environment, workflows, integrations, security requirements, and business objectives, then design and demonstrate how Open can solve them. You will be heavily involved in enterprise sales cycles, from the first technical discovery call through solution design, demos, pilots, security reviews, and handoff to implementation. This is not a role where you simply give standard product demos. You should be comfortable understanding complex systems, APIs, enterprise software, AI agents, telephony, workflows, and customer support infrastructure. Responsibilities Join enterprise sales calls and lead technical discovery with prospects. Understand the customer's existing architecture, systems, workflows, integrations, and operational requirements. Design proposed Open solutions around each customer's use case. Build highly customized demos and proof of concepts for strategic opportunities. Configure AI agents, workflows, integrations, APIs, and automations for demos and pilots. Explain Open's architecture, AI stack, integrations, security model, infrastructure, and data flows to technical stakeholders. Work with customer engineering, security, IT, operations, and procurement teams. Answer technical questions during RFPs, security reviews, vendor assessments, and procurement processes. Work with Open's engineering and product teams when a deal requires new functionality or deeper technical validation. Help define technical scope and success criteria for pilots and proof of concepts. Identify technical risks early in the sales process and help resolve them before they block a deal. Support integrations with platforms such as Salesforce, Zendesk, Intercom, Genesys, ServiceNow, CRMs, ERPs, payment platforms, and internal APIs. Help customers understand how Open can interact with their backend systems through APIs, MCP, webhooks, workflows, and custom integrations. Demonstrate AI voice, email, chat, WhatsApp, workflow automation, and agentic use cases. Create reusable technical documentation, demo environments, architectures, and solution patterns for the sales team. Provide structured feedback from prospects to Product and Engineering. Ensure a clean technical handoff from Sales to the implementation and customer success teams. What Success Looks Like Within your first…
