Requirements

5+ years in a Solutions Engineer, Pre-Sales Engineer, or Technical Account Executive role in B2B SaaS, fintech, or payments.
Demonstrated track record selling to or supporting enterprise and mid-market clients in a technical capacity.
Hands-on experience with REST APIs: reading documentation, testing endpoints, debugging payloads independently.
Experience working directly with PSPs or payment gateways (e.g. Stripe, Adyen, Braintree, Checkout.com).
Native or near-native English as you will lead technical conversations with senior stakeholders at enterprise prospects.
Strong commercial instinct: you understand that your technical work is in service of winning the deal.
Ability to simplify complex technical concepts for non-technical audiences such as merchants, finance teams, legal, C-suite.

Nice To Haves

Background in the chargeback, dispute management, or payments fraud domain — you already speak the language.
Experience in fintech or payments infrastructure companies (acquirers, PSPs, gateways, fraud/risk platforms).
Experience authoring Statements of Work or complex technical scoping documents.
Exposure to data enrichment pipelines or event-driven data flows.
Experience selling into US enterprise retail, travel, or marketplace verticals.

Responsibilities

Lead technical discovery on qualified prospects: understand their payment stack, PSP(s), data architecture, chargeback volume, and existing dispute processes.
Define and scope the integration approach: API connectivity, PSP evidence retrieval, data enrichment options, and any custom requirements.
Identify gaps, risks, and blockers early and surface them clearly to Sales and internal stakeholders.
Act as the internal relay between Sales and Product/Engineering when non-standard requirements surface during the sales cycle.
Deliver compelling, tailored technical demonstrations and adapt to the prospect's actual environment, stack, and use case.
Build and run proof-of-concept (POC) sessions that prove Justt's fit technically and commercially.
Handle technical objections confidently and independently turning blockers into reasons to move forward.
Translate scoping outputs into a precise, commercially sound SOW: integration approach, timelines, data requirements, and acceptance criteria.
Own the SOW as a living document through the sales cycle and updating it as requirements evolve.
Hand off a clean, complete SOW to the onboarding SE team at contract signature.
Operate as a true partner to the Account Executive, not a support function. You co-own deal progression on the technical track.
Know when to go deep and when to keep it simple. Prospects should leave every call feeling confident, not confused.
Represent Justt's technical credibility across the US market: in enterprise and fintech environments where the bar is high.
Maintain a clean Jira board for all active pre-sale engagements; flag capacity and prioritization issues early.
