Back End Developer

We're building something that doesn't exist yet — and we're looking for an Ad Tech Engineer based in Berlin to help us do it. Our model is simple: we deliver advertising revenue back to independent local broadcasters in developing countries. What makes this technically interesting: → We're building a first-party ad server and DMP from scratch on a lean open-source stack (Python / FastAPI / PostgreSQL / AWS) → Audience measurement via Triton Webcast Metrics — certified from day one → Telco data enrichment via AWS Clean Rooms — matching our listener profiles against subscriber data from Telcos to create targeting capabilities that don't exist anywhere else in this market → Serving audio at 12 kbps on 2G networks and 48 kbps on 4G — every byte counts What we're looking for: → Strong Python / backend engineering → Experience with ad tech: OpenRTB, VAST, Prebid, or similar → AWS experience (ECS, RDS, CloudFront, or Clean Rooms a plus) → Interest in working on something that matters beyond the sprint board If this sounds like your kind of problem please mail to [email protected]
