(Senior) Customer Engineer (m/f/d)

Empower every employee.

AI has changed how office workers work. For the 80% of the global workforce who are not desk-bound, it has hardly arrived yet. Flip AI changes that.

Flip AI is the #1 Frontline Agentic Operating System (OS) for building, automating, and orchestrating any use case for frontline teams, on a foundation of secure identity, communication, and strong UX. In practice, this means: one app through which frontline employees in retail, production, and logistics can access their systems, manage their processes, and use AI.

More than 1,000 brands trust Flip AI, and over two million people worldwide use the platform at companies like Bosch, REWE, FORVIA HELLA, and Greif. In August 2026, Notion Capital and HV Capital invested again with a new round of $25 million, bringing the total to over $85 million.

Our Mission: Connect every employee to everything they need in one touch.

Job Description

As a Customer Engineer, you will work at the interface between our product and our customers' environment: their identity stack, their HR systems, their security review, their AI roadmap. You will take a tenant from zero to hundreds of thousands of active users and decide how the technical side will be solved. Sometimes by designing the integration and enabling customer-side IT to build it themselves, sometimes by building the first version yourself and then handing it over. This includes the part where our AI goes live with the customer: agents in the app, tool access via MCP, and the authentication questions underneath that nobody has solved yet.

What awaits you here

• End-to-end technical responsibility: You will be responsible for the technical side of our enterprise onboardings, from the initial architecture discussion to stable broad rollout.

• Integrations that make Flip AI viable: You will design and deliver identity and authentication (OIDC, Entra ID, Frontline Identity), SCIM provisioning, REST APIs, and connections to HR and operational systems like SAP SuccessFactors, Workday, or UKG.

• Advise and empower instead of doing it yourself: You will guide customer-side IT, their partners, and our external development partners to a solution that you yourself would endorse, and ensure that it can be operated without you.

• Build where it solves the rollout: Where building is the fastest way to prove an approach or to get a rollout back on track, you will build the first version and then cleanly hand it over with documentation and a handover meeting so that it endures.

• AI where it meets the customer: You will shape how agents, tool access via MCP, and agent-to-agent scenarios are received in real enterprise environments, including the auth and data boundaries that must be maintained.

• Technical authority in the account: You will align requirements with project management, IT, security, business departments, and works councils, make technical decisions, and feed back the gaps you identify to our product and engineering team. Expect regular travel to customers, approximately 10 to 30 percent of your time.

What you bring to the table

Must-haves

• Approximately 3 to 5 years (or more) in IT or tech consulting, Customer Engineering, Forward Deployed Engineering, Solutions Engineering, or SaaS implementation, with real enterprise experience.

• Hands-on experience with enterprise integration and identity: SSO and authentication (OIDC, OAuth, Entra ID or comparable), REST APIs and API-based integrations that you have delivered in real enterprise IT landscapes.

• Technical responsibility with customers in enterprise projects where you made technical decisions jointly with IT, Security, and business departments, not just coordinated them.

• Real technical depth without writing product code full-time: You read code, review a design, debug an integration, and build a working prototype.

• German at C1 level or higher and fluent English.

Nice-to-haves

• Experience with SCIM provisioning and connections to HR or workforce systems like SAP SuccessFactors, Workday, or UKG.

• A well-founded, current view on where agentic AI is heading: MCP, A2A, EMA, and the authentication questions underneath. We are looking for someone who closely follows the field and has their own opinion on it, not years of experience that don't exist yet.

• Prior experience as a Customer Engineer or Forward Deployed Engineer at a product company rather than exclusively in traditional consulting.

• Workflow automation tools (n8n or similar), routine with logs, metrics, and dashboards, or experience with co-determination and data protection in an enterprise environment.

What we offer you

• Work Mode: We are remote-first, giving you the flexibility to work from home. At the same time, we highly value the benefit of personal collaboration. Depending on the role, you will occasionally participate in team events, workshops, or meetings at our offices in Berlin or Stuttgart – always with sufficient advance notice, of course. We will discuss the exact balance transparently during your application process.

• Work-Life Balance: We don't want you to get stuck to your desk chair, so we cover the costs for your E-Gym Wellpass membership and offer Job-Rad leasing.

• Celebrating Success: You'll meet highly motivated and dedicated people in a relaxed working atmosphere.

• In the thick of it, not just on the sidelines: You actively shape Flip AI. Incidentally, you are an enabler of the rapid growth process of a young tech company and grow with your goals. Good mood guaranteed.

• Happy to be a Flipster: Look forward to regular team events and culture days that unite us as Flipsters.

• Working abroad: At Flip AI, you can also work from other European countries; let's talk about workations in the interview.

To make our job ads easier to read, we use the masculine form of address in the text. At Flip AI, everyone is welcome, regardless of your gender or age. Sexual identity, origin, religion, worldview, and disabilities play no role. The most important thing is that YOU fit with us!
