Senior Backend Engineer (m/f/d), 2 positions

NYBA is the Revenue OS for live entertainment. The platform forecasts ticket demand for every show, runs campaigns on every channel that sells tickets, and measures every euro against verified ticket sales from the ticketing system. 75M+ tickets sold, 1,200+ events a year and clients such as Live Nation, Cirque du Soleil and BBC Earth.

Please note: our engineering team works in English. German is a plus, not a requirement. You should be based in the EU.

Your role

Every campaign at NYBA should go live without a human touching it. Today parts of that still run on no-code tools and manual checks. You rebuild the core in code: the build engine for the ad platforms, the payment and ledger system, and the API that ticketing platforms use to plug NYBA into their dashboards. Two positions are open, one focused on the build engine, one on payments and the partner API.

What you will do

• Build the campaign build engine for the Meta, Google and TikTok ad APIs, including a build loop that verifies every campaign before it goes live
• Build payments and the ledger: wallet, charge after campaign end, dunning, automatic pause
• Design and ship the partner API and webhooks for ticketing platforms
• Write background jobs that are idempotent, retry safely and are easy to monitor
• Model campaign, event and order data cleanly in PostgreSQL
• Add tests, logging and alerts so failures are found by the system, not by customers
• Review code and help set the standards of a young engineering team
• Replace manual operations with product features, one escalation at a time

What you bring

• 5+ years of backend engineering in TypeScript (Node) or Python
• Production experience with PostgreSQL, queues and background workers
• You have integrated third-party APIs at scale and handled their rate limits, errors and version changes
• Experience with payments (Stripe or similar) or with ad platform APIs
• You write tests and care about observability
• You work independently, ship in small steps and document what you build
• Comfortable in a small team where you own whole features
• Fluent English; German is a plus
• Based in the EU, remote

Bonus points

• Experience with Supabase
• Meta Marketing API, Google Ads API or TikTok Marketing API
• Experience with AI-assisted development and AI agents
• Event-driven architectures
• Startup or scale-up experience

What to expect

• Work directly with the Head of Engineering and the founder
• A clear backlog in a clear order, no feature theatre
• Market-rate fixed salary and a share in NYBA's success
• Remote within the EU, with team days in Frankfurt
• Modern AI infrastructure and demanding technical challenges
• International clients such as Live Nation, Cirque du Soleil and BBC Earth
• Flat hierarchies and fast decisions
• Flexible hours, extra holiday days, training and team events
