Job Description

This isn’t your regular job. Almedia is a place where those who want to push harder can accelerate their careers faster than anywhere else. We’re aiming to become Germany’s second bootstrapped unicorn. Almedia is already Europe’s #3 fastest-growing company in 2025 (FT1000).

We are building the future of marketing by rewarding our community of over 60 million users for engaging with our advertisers’ products. We are offering a new way to acquire users for the biggest companies in the world.

We’re looking for a Backend Engineer to co-own and scale our Advertiser Platform — the internal system powering offer, game, and budget management across our ad network products.

If you like owning backend systems end-to-end, shipping fast, and improving infrastructure while building real product features, let’s talk.

Tech Stack 💻

• Python, FastAPI (Pydantic)

• MongoDB, BigQuery, Memcached

• Docker, GitHub Actions, PM2, Hetzner

• Next.js / React / TypeScript (you'll touch frontend but backend is the focus)

• Google Cloud Platform (BigQuery, Cloud Storage)

What You’ll Do 🎯

• Own and extend our FastAPI backend (routers, services, data layer).

• Build end-to-end features from MongoDB/PostgreSQL through API to our Next.js frontend.

• Maintain strict backend–frontend contracts using Pydantic (auto-generated TypeScript types).

• Build and optimize our Database layer/access (queries, caching with Memcached/Redis, DBT/Dataform).

• Integrate third-party platforms (HubSpot, Slack) & different internal services via API

• Improve CI/CD (GitHub Actions), Docker-based deployments (Hetzner / PM2), staging environment, build/expand our testing suite, and own observability.

What You’ll Bring 💡

• Strong Python experience (FastAPI or similar async frameworks).

• Solid API design and data modeling skills.

• Hands-on experience with MongoDB and/or PostgreSQL (or comparable).

• Experience with BigQuery or similar analytics systems.

• Comfortable owning features from idea to production.

• Experience with Next.js / React / TypeScript is a big plus.

What Makes You a Great Fit 🌟

• Ownership-driven and pragmatic.

• Product-minded with a strong quality bar.

• Comfortable in a fast-moving environment.

• Clear communicator in English.
