Solution Engineer - NYC

About the role

We're seeking an experienced, independent Solution Engineer to join our growing New York team. This is a critical role requiring complete ownership of complex technical processes — from initial pre-sales through full customer onboarding. The ideal candidate is a seasoned professional with exceptional communication skills and the ability to lead processes independently in a fast-paced startup environment.

Location & travel: This position is based in New York, NY. We operate on a hybrid model, with time split between our NYC office and remote work. Some travel is expected — to meet prospective and existing clients, support on-site integrations, and collaborate with teammates — so candidates should be willing and able to travel as needed.

Responsibilities

• Take full ownership of the technical aspects of the sales cycle, including a deep understanding of customer requirements and matching them to the right solutions.
• Conduct professional product demonstrations and technical workshops for prospective clients.
• Develop and present customized solutions that address specific client challenges and business objectives.
• Lead the complete technical implementation of Justt's solutions for new clients, ensuring seamless integration with their existing systems.
• Provide comprehensive training and ongoing support so clients maximize the value they get from our solutions.
• Proactively identify and resolve technical challenges throughout the onboarding process.
• Work closely with sales, product, customer success, and engineering teams to exceed client expectations.
• Translate client needs into clearly defined technical tasks for R&D and help drive them to completion.
• Contribute to the development of technical documentation and training materials.

Requirements

• 5+ years of proven experience in solution engineering, pre-sales, or technical consulting roles.
• 2+ years in fintech or payments — a strong bonus.
• Deep understanding of AI-powered solutions, payment processing systems, and their applications in fraud prevention, chargeback management, and dispute resolution.

Skills

• Proven, hands-on experience with integration processes, APIs, and data mapping.
• Strong problem-solving abilities and a critical-thinking approach to client challenges.
• Ability to define and scope technical tasks for engineering teams and manage them through delivery.
• Strong project management capabilities — able to plan, coordinate, and drive multiple onboarding and integration projects to completion, keeping stakeholders aligned and timelines on track.
• Exceptional communication and presentation skills — able to explain complex technical concepts to both technical and non-technical stakeholders.
• Independence and proactivity — you thrive managing multiple projects simultaneously in a rapidly changing environment.
• Composure under pressure and a customer-first mindset.
• Cultural fit for a fast-paced, creative startup atmosphere and our hybrid NYC team.
• Fluency in English; additional languages are advantageous.

Benefits

At Justt you'll take real ownership from day one, work alongside a talented and collaborative team, and help shape how the world's merchants win back revenue lost to chargebacks.
