Customer Integration Engineer (f/m/d)

Remote, München - HQ, Stuttgart Steyg

Full-time

Permanent employee

About the Job

We are looking for a Customer Integration Engineer (f/m/d) to own the technical onboarding of our largest enterprise customers. You will lead data migrations from customer legacy systems into Certivity, build the API connectors that link Certivity to customer tooling, and serve as the direct technical contact for customer IT, engineering, and regulatory teams.

This is a hands-on engineering role with daily (remote) customer contact. You will write code most of the time, but you will also explain your work to non-Certivity engineers, gather requirements directly from customer experts, and translate enterprise customer needs into shipped backend features.

What you will do

Run data migrations from customer legacy systems (e.g. IBM DOORS, Polarion, internal databases) into Certivity, including schema mapping, validation, and post-migration reconciliation.
Build and maintain API connectors between Certivity and customer services.
Work directly (usually remotely) with customer IT, engineering, and regulatory teams to scope, plan, and execute integrations.
Use AI coding tools (Claude Code, Cursor, Copilot) as part of your daily workflow to move efficiently across our Python and Java codebases.
Own each customer technical integration end-to-end, from kickoff to handover.

Your profile

Must-haves

4+ years of hands-on backend software engineering experience.
Hands-on experience with data migrations between systems, including schema mapping, data validation, and reconciliation.
Strong Python or Java backend skills (we use both; you can be strong in one and willing to work in the other with AI tooling support).
Experience integrating with REST APIs and working with relational or document databases (PostgreSQL, MongoDB or comparable).
Comfortable working with cloud infrastructure (AWS, Azure, or GCP) and Docker.
Excellent English communication skills, written and spoken, at a level where you can lead a technical call with a customer IT lead without preparation. C1 or higher.

Nice to have

Experience with IBM DOORS, Polarion, or other requirements management systems
Familiarity with automotive or other regulated industries
Background in enterprise SaaS implementation or customer-facing engineering
Spring Boot experience
