Skills
Must have
- You've operated real distributed systems, not just built a monolith and called it done.
- You're just as comfortable tracing a bug from a UI symptom (web or native) down through the application server into the backend that caused it as you are building the fix on either end
- You're comfortable being dropped into someone else's code, in a language you may not know, with real production traffic on it, and using AI tools plus your own judgment to figure out how it actually b
- You're honest about uncertainty. "I don't know, let me check the logs" beats a confident guess, from you or your AI tools
Full description
We believe talent is everywhere. The chance to live from it isn't.
Millions of creators are talented and invisible at the same time. The value they create flows to middlemen, while the brands who want to reach them are stuck in a non-transparent, fragmented market. So we built the tools to fix both sides at once.
Creators turn an account into an income: join a campaign in minutes, make something they're proud of, and get paid fairly for creativity, not follower count. Brands brief once, activate hundreds of creators, and see content live within 24 hours.
Next year, 10,000 creators will make a living from WePush. When a creator earns, a brand grows. When a brand grows, more creators earn. WePush is the fastest-growing creator marketing platform in Europe, with over 150,000 creators and 500,000+ collaborations powering brands like L'Oréal, ABOUT YOU, Zalando, and Sony Music. Two numbers matter to us: how many people make a living through WePush, and how many millions of people brands reach through them.
**Technical Overview:
**We run on a real distributed system: Angular and React frontends, a native iOS app, a Node/TypeScript application server handling booking and matching logic, a fleet of independently deployable backend services on Kubernetes, a real-time layer, a ledger that moves actual money, and a small army of scrapers. We're looking for a Fullstack AI Product Engineer who is comfortable moving across all of those layers and who uses AI agent tools as genuine leverage. We use these tools daily to read unfamiliar services, ship changes, and move fast.
Tasks
What you'll actually work on:
- A native iOS app: SwiftUI, rewritten natively
- Web Frontend: our marketplace apps are built in Angular, and newer internal tooling is React.
- An application server layer: a Node/TypeScript service sitting between the frontend and the backend fleet, handling booking, scheduling/matching logic, invoicing, and PDF generation.
- A polyglot microservices fleet, with a shrinking Hack/HHVM legacy core and a growing set of services in Node.js and Go, each independently versioned, containerized, and deployed via Helm to Kubernetes
- A real CI/CD pipeline: GitLab CI building images with Kaniko, tag-based semver releases (nightly unstable builds, stable releases promoted through dev to test to a manually gated prod), and cross-service pipeline triggers when a shared dependency publishes
- Scheduled workloads at scale: a couple dozen CronJobs per environment (reminders, payout checks, stat rollups, token refreshes, media polling), each independently schedulable, tunable, and killable without redeploying the whole service
- Money movement: a ledger service backing real balances and payouts
