Coinflow is a trailblazing startup headquartered in Chicago, dedicated to revolutionizing payments. We enable merchants and marketplaces to accept global payment methods with instant settlement and fraud guarantees. Over the past year and a half, we’ve become a leader in the digital payments ecosystem—powering the next generation of online commerce through speed, trust, and innovation.

Join us to help shape the future of payments in a dynamic, collaborative, and fast-paced environment where your work directly drives customer success and company growth.

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.
