About Justt
Justt helps many of the world’s largest and most recognizable brands turn chargebacks from a constant headache into a managed, predictable part of doing business. Our AI-driven platform powers chargeback operations at scale, automating disputes end-to-end, recovering revenue that would otherwise be lost, and removing a major operational burden from finance, risk, and operations teams across multiple markets and verticals.
We’re a global company with teams in diverse disciplines, working closely with leading players in the payments ecosystem. Our culture is built on clear thinking, collaboration, and a strong sense of ownership. At Justt, you’ll partner with product, engineering, data, success, and go-to-market teams to build technology that sits at the core of modern payments and has a direct, measurable impact on the bottom line for some of the biggest companies in the world.
Role Overview
The Pre-Sale Solution Engineer is Justt’s technical co-pilot in the sales process—present from the first meaningful discovery call and fully accountable for all technical workstreams until the contract is signed. This is a pure pre-sale role: you do not own onboarding or post-launch support.
Your focus is singular: help Sales win technically complex, high-value $30K+ CARR/ARR deals across the AMER region. You bring equal measures of technical depth and commercial instinct—you know how to run a rigorous scoping session, understand stakeholder needs, and read a room.
This role sits within Commercial Operations and reports to the Director of Solutions.
Key Responsibilities
Technical Discovery & Scoping
- Lead technical discovery on qualified prospects, including:
- Understanding their payment stack, Payment Service Providers (PSPs), data architecture, chargeback volume, and existing dispute processes.
- Defining and scoping the integration approach, including:
- API connectivity
- PSP evidence retrieval
- Data enrichment options
- Any custom requirements
- Identifying gaps, risks, and blockers early and surfacing them clearly to Sales and internal stakeholders.
- Acting as the internal relay between Sales, Product, and Engineering when non-standard requirements arise.

Demo & Proof of Concept (POC)
- Deliver compelling, tailored technical demonstrations, adapting to the prospect’s actual environment, stack, and use case.
- Build and run proof-of-concept sessions that prove Justt’s technical and commercial fit.
- Handle technical objections confidently—turning blockers into reasons to move forward.
Statement of Work (SOW)
- Translate scoping outputs into a precise, commercially sound SOW, covering:
- Integration approach
- Timelines
- Data requirements
- Acceptance criteria
- Maintain the SOW as a living document through the sales cycle, updating it as requirements evolve.
- Handoff a clean, complete SOW to the onboarding SE team at contract signature.
Sales Partnership
- Operate as a true partner to the Account Executive (AE), co-owning deal progression on the technical track.
- Know when to go deep and when to simplify—prospects should leave every call confident, not confused.
- Represent Justt’s technical credibility across US enterprise and fintech markets, where the bar is high.
- Maintain a clean Jira board for active pre-sale engagements, flagging capacity/prioritization issues early.
Requirements
Must-Have
- 5+ years experience in a Solutions Engineer, Pre-Sales Engineer, or Technical Account Executive role in B2B SaaS, fintech, or payments.
- Demonstrated track record of selling to or supporting enterprise and mid-market clients in a technical capacity.
- Hands-on experience with REST APIs, including:
- Reading documentation
- Testing endpoints
- Debugging payloads independently
- Experience working directly with PSPs or payment gateways, e.g., Stripe, Adyen, Braintree, or Checkout.com.
- Native or near-native English proficiency (to lead technical conversations with senior stakeholders).
- Strong commercial instinct—understand that technical work is in service of winning deals.
- Ability to simplify complex technical concepts for non-technical audiences (e.g., merchants, finance teams, legal, C-suite).

Strong Advantage
- Background in the chargeback, dispute management, or payments fraud domain—familiarity with the terminology speaks volumes.
- 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 markets in retail, travel, or marketplace verticals.
What This Role Is Not
- Onboarding or implementation ownership (transitions to the onboarding SE team at contract signature).
- Post-launch technical support (handled by the full-cycle SE team).
- A demo operator or slide deck builder—this is a technical partnership role focused on deal progression.
- Involvement in every discovery call—only engaged on qualified deals above the $30K+ threshold.
Cross-Functional Interfaces
- Account Executives (AEs): Primary partners; you co-own the technical track of every deal.
- Director of Solutions: Your manager; owns capacity, prioritization, and development.
- Onboarding SE team: Handoff recipients; your output is a clean SOW and complete discovery.
- Product & Engineering: Relay for non-standard requirements and feasibility questions during scoping.
