The Role

The Senior Sales Engineer is a curious, consultative advisor who pairs with sales to win net-new ARR and expand existing accounts. You connect Entersekt's capabilities to the customer's business outcomes: surfacing the real problem behind the stated request, then mapping it to higher approval rates, lower fraud losses, improved regulatory compliance, or an enhanced customer experience.

You partner with Sales as the trusted technical advisor on qualified opportunities across our payments and authentication suites. Customers are predominantly issuers, merchants, acquirers, and payment networks. The work is technical, the buyers are sophisticated, and the regulatory context (SCA, GDPR, card network rules, and EMV 3DS specifications) is non-negotiable.

This is not a product-led demo role—we sell on value, not features.

Key Responsibilities

• Engage qualified opportunities as the technical lead, partnering with Account Executives to win net-new ARR and surface expansion opportunities in the existing book.
• Run discovery with technical and business stakeholders to understand pain points, current architecture, and commercial drivers; translate these into use cases and a credible Entersekt solution narrative.
• Articulate Entersekt’s differentiators in language the customer can use internally to build their own business case.
• Address technical objections directly, including comparative positioning against incumbent vendors and in-house alternatives.
• Lead technical workshops, demos, and POC scoping with customer and partner technical teams.
• Lead the technical sections of RFP/RFI responses in partnership with Sales.
• Contribute to solution design alongside Solution Architecture, with clear scope boundaries: SE shapes the win, SA owns the build.
• Deliver clean handovers to Solution Delivery at contract signature so the delivery team can execute without re-discovery.
• Escalate product gaps, integration blockers, and competitive intelligence to Product, Engineering, and Sales leadership.
• Build product, domain, and integration knowledge to handle most customer queries independently.
• Produce technical content that accelerates pipeline: customer-specific briefings, integration guidance, and comparative positioning material.

Skills and Experience

• Experience: 7+ years in a customer-facing pre-sales, solutions engineering, or technical consulting role, ideally within a SaaS environment specialising in payments or authentication.
• Deep Technical Expertise in one of:
  • Payments: EMV 3DS, 3DSS or ACS operations, issuer/acquirer integrations, transaction flows, authorisation rate optimisation; or
  • Authentication: Strong Customer Authentication (SCA), out-of-band MFA, mobile and web SDK integration, trusted device endpoints, orchestrated authentication journeys.
• Domain Fluency: Working fluency in the secondary domain sufficient to support an opportunity end-to-end.
• Commercial Credibility: Proven track record of carrying technical credibility into commercial conversations with technical and executive audiences.
• Regulatory Environments: Comfortable operating in regulated environments; financial services experience is strongly preferred.
• Education: Engineering, Computer Science, or related technical degree, or equivalent practical experience.
• Travel: Typically 25–30%.

Personality Attributes

• Curious: You ask the next question and assume the stated requirement is rarely the real requirement.
• Tenacious: You escalate, follow up, and hold colleagues to commitments to get customer answers.
• Self-sufficient: You build knowledge actively and carry most customer conversations alone.
• Consultative: You sell value, not features, sitting on the customer's side of the table without losing commercial positioning.
• Comfortable in Ambiguity: You find a clear path in fast-moving fintech, evolving products, and changing regulation.
• Strong Communicator: Effective across whiteboards, slides, written prose, or code.
