PreSales Engineer - NYC

Description

About this Position:

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 regions and verticals.

We’re a global company with teams across markets, and 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

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 deals.

You will work closely with Account Executives across the AMER region, engaging on strategic accounts and deals above the defined threshold ($30K+ CARR/ARR). You bring equal measures of technical depth and commercial instinct: you know how to run a rigorous scoping session and how to read a room.

This role sits within the Commercial Operations department and reports to the Director of Solutions.

Key Responsibility:

Technical Discovery & Scoping

• 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.

Demo & Proof of Concept

• 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.

Statement of Work (SOW)

• 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.

Sales Partnership

• 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.

Requirements

Must-Have

• 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.

Strong Advantage

• Background in the chargeba
