Role Profile

• Department: Customer Solutions

• Team: Sales Engineering

• Reports to: Head of Customer Solutions

We are seeking a Senior Sales Engineer who is ready to bridge the gap between complex technical architecture and strategic business value. This role is designed for a dedicated professional who thrives on solving the deep-seated "data silo" problems of enterprise merchants and is driven to evolve into a future leadership position. You will be the technical heart of our sales process, partnering with E-commerce, Financial, and Product executives to demonstrate how agentic intelligence solves fragmented data issues and optimizes cost structures.

Key Responsibilities

• Strategic Demos & Storytelling: Own the technical demo process, translating "agentic intelligence" into clear, execution-ready outputs for C-suite stakeholders.

• Value Engineering: Work with enterprise clients to quantify ROI by identifying hidden costs in manual data cleaning versus the growth potential of AI-driven optimization.

• Technical Discovery: Conduct deep-dives to uncover specific pain points, such as the lack of business context in off-the-shelf AI tools or constant firefighting in operational teams.

• Bespoke Presentations: Customize technical presentations and POCs that reflect the specific KPIs, goals, and operational nuances of the merchant.

• Pipeline & Project Management: Manage the technical stages of the sales pipeline, ensuring all cross-functional intelligence requirements are met for a seamless transition.

• Voice of the Customer: Act as a critical link between the field and the Product team, using on-the-ground experience to influence the development of our multi-agent systems and "Bespoke Strategists".

Mandatory Qualifications

• Industry Experience: 5+ years of experience in a Sales Engineering or Pre-Sales role specifically within the SaaS and Payments sectors.

• Language Proficiency: Native or professional fluency in both Spanish and English is required.

• Technical Acumen: Deep understanding of APIs and SFTP integrations, as well as no-code connections with major PSPs and acquirers such as Adyen, Braintree, and Fiserv.

• Enterprise Expertise: Proven track record of navigating complex sales cycles with large-scale, global enterprise clients.

• Value-Based Selling: Strong background in value engineering, with the ability to build business cases around cost-to-performance insights and revenue impact.

Preferred Attributes (Value Engineering & Growth)

• Benchmarking Proficiency: Ability to compare a merchant’s current performance against industry payments benchmarks to surface proactively identified opportunities.

• Operational Insight: Familiarity with the operational friction points of finance and tech teams, including chargeback data management and authorization outcomes.

• Scenario Simulation: Skilled in using analytics tools to perform scenario simulations and forecasting to prove potential gains in acceptance rates.

• Opportunity Detection: Expertise in building systems for high-impact opportunity detection and sizing.

What will you find when you join DEUNA?

• A multicultural team distributed throughout LATAM

• Dynamism, agility and constant innovation

• Being part of a high-impact solution for an entire region

• The best tools and technology to operate

• Being part of the startup culture.

• We are in full expansion!
