Staff Engineer

Do you love untangling messy systems shipping real improvements and setting a higher engineering bar

Join meinUnterricht Germanys leading platform for teachers as a Staff Engineer.

Youll own the architecture of the core systems that run our business and decide how a decade of accumulated complexity gets simplified. We want a hands-on architect who questions the status quo and pushes our AI-first engineering even further.

Our Tech Stack

We believe in transparency. You will be working across both legacy and modern systems with a strong mandate to help us consolidate and modernize over time.

Where we are going (the new stack): Monorepo architecture APIs built with Hono Prisma for DB migrations Vitest PostgreSQL Stripe and AWS CDK for infrastructure.

What we currently have: React Redux (Hapi) MongoDB (Mongoose) MySQL Zuora and AWS (EC2 ECS CloudFront).

• Drive System Architecture: Lead the technical direction for our core systems including subscription infrastructure cloud foundations shared backend services database architecture and data pipelines.

• Modernize the Foundation: Identify what should be kept replaced merged or removed across our legacy systems and turn that into a pragmatic target architecture with an execution path.

• Technical Ownership: You stay deep in the code on the highest-impact problems. You make the architecture decisions and the hard technical tradeoffs and you set the bar others build to.

• Raise the Bar with AI: Model an AI-first engineering culture by using tools like Claude Code Codex or similar across coding migrations infrastructure and workflow automation.

• Broad Systems Depth: Strong backend (fluency in TypeScript/) and infrastructure experience across areas like databases cloud services queues caching networking integrations or pipelines. Not just one narrow specialty.

• Migration Experience: You have led or played a major role in moving production systems from old to new and you understand the messy middle: dual-running rollout strategy data integrity and rollback planning.

• Product Sense: You think beyond the system to the user and the business. You balance long-term architecture against the value that needs to ship now.

• Cloud & Platform Experience: Youre comfortable working in AWS-heavy environments and have practical experience improving infrastructure reliability and developer workflows. IaC experience is a big plus.

• AI-Native Mindset: You actively use AI tools in real engineering work and see them as a serious force multiplier not a gimmick.

• Meaningful Product: Build infrastructure behind a platform that helps tens of thousands of teachers prepare better lessons faster.

• Real Ownership: Youll own a critical systems domain with direct impact on revenue product velocity and the technical future of the company.

• AI-First Engineering Culture: We invest heavily in AI tooling (Claude Max Plan or equal) and expect engineers to use it deeply and practically in day-to-day work.

• Strong Berlin Setup: Work from our office at Potsdamer Platz with a hybrid setup that supports both focused execution and in-person collaboration.

• Meaningful Benefits: A device of your choice Deutschland Ticket or Urban Sports Club work remotely from anywhere in the world for up to 10 days per year Jobrad and more.

• Remote coding challenge

• Technical interview (video call)

• System design interview (preferably on site in our offices in Berlin)

• Technical leadership interview (preferably on site in our offices in Berlin)
