Role
Who you are
- 10+ years of professional backend engineering experience, including at least 2 years in an engineering management or technical lead role
- Strong PHP development skills, including solid knowledge of design patterns, SOLID principles, and clean code practices
- Production experience with identity, authentication, or authorization systems at scale, including a solid understanding of OAuth 2.0, OIDC, and the realities of running multi-tenant, high-availability systems in security-critical domains
- Experience leading distributed engineering teams and managing stakeholder relationships across functions
- Fluent English communication skills. German is a plus
- Nice to have: hands-on Keycloak experience (configuration, custom authenticators, realm management, identity brokering)
- Nice to have: familiarity with enterprise identity protocols (SAML, SCIM, LDAP), PHP frameworks like Symfony or Laravel, relational databases (PostgreSQL, MariaDB, MySQL), or containerized cloud infrastructure (Kubernetes, Docker, CI/CD)
- We welcome people of all backgrounds, identities, and perspectives, because transforming education for a better tomorrow starts with equal opportunities today. If you’re excited about this role but don’t meet every requirement, we’d still love to hear from you
What the job involves
- As Engineering Lead for Identity, you own and evolve Seven Education's Identity & Access Management platform
- The platform is built on Keycloak and serves more than 10 million users across Europe: schools, teachers, parents, and students who rely on it to access our ecosystem every single day
- You combine hands-on engineering with technical leadership, ship code yourself, and shape the architecture of a security-critical system at scale
- Lead the Identity team, a distributed group of engineers across Europe: run 1:1s, remove blockers, set technical direction, and grow the people on your team
- Drive the SSO rollout across all our products (Sdui App, Pupil, Fox, Educamos, Additio, Educa) and own the migration from our legacy authentication bridge to the unified Keycloak platform
- Own the technical architecture of the IAM platform: Keycloak configuration, custom authenticators, identity brokering, and the multi-tenancy model designed for 10M+ users, 50K+ tenants, and 10K concurrent authentications at sub-100ms latency
- Act as the primary integration partner for product teams adopting centralized IAM: define API contracts, review integrations, and ensure a smooth developer experience
- Stay hands-on. Write production code, review pull requests, and make pragmatic technical decisions alongside your team
- Mentor engineers, foster knowledge sharing, and continuously raise engineering standards
- Collaborate closely with the Director of Domain Engineering to align roadmap, priorities, and cross-team dependencies

Our take
Germany-based Sdui is helping schools and daycares transform for the digital age, with a range of GDPR-compliant communication solutions. From its "digital classroom" - which allows chat and video conferencing - to parent letters and push notifications, Sdui provides all the tools for enhancing communication in the education and childcare spaces.
Serving thousands of schools and daycare centres across Europe, the company has already taken strides towards its vision of a world in which technology enables everyone to benefit from the best possible education. Strong funding and a string of acquisitions support the company in accelerated international expansion and scaling of its products.
As the company has expanded, it has become a group of many brands like KidsFox, SchoolFox, Additio App, Educamos, Konecto and Pupil. This group has now rebranded to Seven Education, which Sdui is considered a part of. The company itself continues its aim of becoming a first-choice partner for educational institutions across Europe.
