Conduct technical discovery calls with prospective customers to understand business objectives, technical requirements, integration constraints, and success metrics, and document findings in the CRM.
Deliver engaging, tailored product demonstrations and proof-of-concept (POC) sessions that align product capabilities to customer use cases and ROI objectives, both live and recorded.
Design, configure, and present solution architectures, including reference designs, network diagrams, API/integration flows, and security considerations for enterprise and SMB customers.
Create and maintain technical proposals, solution briefs, response templates for RFP/RFI/RFQ, and statement of work (SOW) drafts that clearly articulate value, scope, and technical assumptions.
Collaborate with account executives to qualify leads, prioritize opportunities, and develop account strategies that maximize win rates and deal size.
Configure pricing and product bundles using CPQ or quoting tools; produce accurate quotes, bill of materials (BOM), and configuration guides for sales review and approval.
Execute hands-on POCs, sandbox builds, or lab environments to validate technical feasibility, troubleshoot issues, and present test results with recommended next steps.
Act as the technical escalation path during the sales cycle — rapidly triage customer technical concerns, work with engineering/product teams, and provide timely resolutions.
Maintain and update demo environments, scripts, and sample data sets to ensure demos are reliable, reproducible, and showcase the latest features and competitive differentiators.

Build repeatable playbooks for common verticals, use cases, and integration patterns to accelerate time-to-demo and reduce custom engineering efforts.
Ensure compliance with internal processes for security, privacy, and regulatory requirements during technical evaluations, including NDAs, data handling, and access controls.
Monitor competitive landscape during sales cycles — perform feature comparisons, price-to-value analysis, and present defensible reasons to select your solution over alternatives.
Manage multiple concurrent POCs and proof-of-value engagements with clear timelines, success criteria, and stakeholder communication plans.
Partner with onboarding and professional services teams to ensure smooth transition from signed contract to technical onboarding and implementation kickoff.
Maintain up-to-date knowledge of cloud platforms (AWS, Azure, GCP), networking fundamentals (TCP/IP, VPNs), identity providers (SAML, OAuth), and common enterprise integrations.
