Role Overview We are seeking a Senior Pre-Sales Engineer to bridge the gap between complex technical architectures and strategic business outcomes for enterprise merchants. This role sits at the heart of our go-to-market motion, partnering closely with Sales, Product, and Customer Solutions to demonstrate how agentic intelligence and advanced data orchestration unlock growth, reduce operational friction, and optimize cost structures. You will lead the technical side of the sales process—translating fragmented data, payment complexity, and operational pain points into clear, value-driven solutions for C-level, finance, and e-commerce leaders. This role is designed for a high-impact individual with the potential to grow into future leadership within Sales Engineering or Solutions Architecture. Key Responsibilities Pre-Sales Strategy & Execution - Own the technical sales cycle from discovery through deal closure, acting as the main technical advisor to enterprise prospects. - Partner with Sales to position agentic intelligence, multi-agent systems, and bespoke strategists as solutions to real operational and financial problems. - Manage all technical stages of the sales pipeline to ensure a seamless transition into onboarding and delivery.

Value Engineering - Quantify ROI and business impact, identifying hidden costs in manual processes, data silos, and inefficient payment flows. - Build value-based business cases that connect cost, performance, and revenue outcomes. Technical Discovery - Conduct deep technical and operational discovery to uncover: - Data fragmentation and lack of business context in existing AI or BI tools - Payment inefficiencies (acceptance rates, chargebacks, reconciliation, routing) - Operational bottlenecks in finance, tech, and operations teams Bespoke Presentations & POCs - Create customized presentations and proofs of concept aligned to each merchant’s KPIs, goals, and operating model. - Map how our platform integrates into the merchant’s current PSP, acquirer, and data stack. Voice of the Customer - Act as a critical feedback loop to Product and Engineering, using insights from the field to shape the evolution of our multi-agent platform and AI strategists. Mandatory Qualifications - Industry Experience: 5+ years in Sales Engineering, Pre-Sales, or Solutions Consulting within SaaS and Payments. - Languages: Native or professional fluency in Spanish and English. - Payments & Integrations Expertise: Strong understanding of APIs, SFTP integrations, and no-code connectors - Enterprise Sales Experience: Proven ability to navigate complex, multi-stakeholder sales cycles with global enterprise customers. - Value-Based Selling: Demonstrated ability to build cost-to-performance and revenue impact business cases. Technical Toolkit: - Postman - Ability to read and understand API payloads - Strong at reading and interpreting technical documentation - Comfortable explaining integrations and flows in demos (Coding or implementation is not required — this is a demo, discovery, and value-engineering role.)
