About the role

We are looking for a Customer Solutions Engineer to take ownership of the technical success of our enterprise banking clients. This is a high-impact, remote consultancy engagement within Europe, requiring availability within ±1 hour CET.

In this role, you will work closely with the CPTO and the Customer team, acting as the primary technical counterpart for global banks operating in highly regulated environments. You will stand at the intersection of product, engineering, and enterprise clients, shaping how our platform scales, integrates, and delivers long-term value.

You own the technical relationship across the client lifecycle. From discovery and architectural guidance to migrations and escalations, you ensure that integrations are scalable, secure, and aligned with product strategy. You are not just solving tickets, you are safeguarding product integrity while building trusted relationships with senior technical stakeholders.

You will guide and elevate support operations and step in directly on complex cases when needed.

The impact you will have

Our clients are global banks operating in highly regulated environments. The way we design and manage technical integrations directly impacts scalability, compliance, and long-term value creation.

You will safeguard the integrity of our product by setting clear architectural boundaries, evaluating change requests rigorously, and avoiding custom consultancy traps. At the same time, you will cultivate trusted relationships with technical stakeholders and help develop support operations that are proactive, efficient, and focused on maximizing value throughout the client journey.

• Security & Auth: Guide bank security teams through the implementation of mTLS, token handling, and user authentication, ensuring they understand the requirements for end-user session handling.

• Feasibility & Scaling: Evaluate client change requests (CRs) and ad-hoc technical demands. Perform research to determine if requests can be met with existing functionality or if they require product development, ensuring we avoid "custom consultancy" traps and maintain a scalable product.

• Migration Leadership: Partner with existing clients to plan and execute technical upgrades.

Client Lifecycle

• Technical Point of Contact: Act as the "face of tech" for enterprise clients. Lead regular technical syncs and provide progress summaries on open issues and Jira tickets.
