About the Role

We’re looking for a Solutions Engineer who is both deeply technical and excited to engage with customers. You’ll work directly with merchants’ engineering teams to design integrations, guide them through successful go-lives, and optimize their implementations to unlock maximum value.

This role doesn’t require prior “customer-facing” experience, but you must be eager to work alongside customers, communicate clearly, and enjoy solving problems in real time. You’ll collaborate closely with Sales during the deal cycle, with Product on shaping the roadmap from customer-driven feedback, and with customers from first integration through long-term optimization.

What You’ll Do

Solution Design & Pre-Sales

• Partner with Sales to scope technical solutions for new deals

• Build proof-of-concepts, demos, and code samples that showcase Coinflow’s capabilities

• Advise customer engineering teams on integration tradeoffs and best practices

Customer Onboarding & Go-Live

• Own the technical onboarding process from contract to production launch

• Work hands-on with APIs, SDKs, and front-end components to support customer teams

• Ensure each go-live is smooth, scalable, and optimized for long-term success

Optimization & Growth

• Analyze data to identify adoption and revenue opportunities

• Guide customers to implement new features, payment methods, or workflow improvements

• Collaborate with Sales to expand accounts through technically credible upsell conversations

Internal Collaboration & Enablement

• Translate customer feedback into clear product insights for Engineering and Product teams

• Build internal tools, documentation, and reusable assets that improve speed to launch

• Help define scalable onboarding and solutioning processes as Coinflow grows

What We’re Looking For

• 2–5 years in a technical role (Solutions Engineer, Integration Engineer, Developer, or similar)

• Strong coding skills in TypeScript and React—comfortable debugging and building with customers

• Solid understanding of REST APIs, integrations, and data flows

• Ability to write and run SQL queries for troubleshooting and reporting

• Excellent communicator who enjoys engaging directly with customer developers and stakeholders

• Self-starter with a bias toward ownership and problem-solving in fast-moving environments

• Bonus: Payments, fintech, or transaction-processing experience

Join the team rewriting how money moves worldwide—and become a driving force in the $194 trillion cross-border payments market.
