AI Product Engineer (Fullstack)

We believe talent is everywhere. The chance to live from it isnt.

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 theyre 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 10000 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 150000 creators and 500000 collaborations powering brands like LOréal 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. Were 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.

What youll 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 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
• A scraper fleet: services that scrape platforms which actively fight back (rate limits bot walls reshaped responses) running on their own schedule with their own failure modes
• A newer AWS/serverless edge: internal tooling and some integrations are moving onto Lambda/API Gateway/DynamoDB. This is where a lot of new greenfield work is happening

What AI-driven builder means here:

• You use AI tools openly as your default way of working to read and understand an unfamiliar service fast not just to generate new code. Half the job is what does this cron job actually do and what breaks if I touch it and AI is how you get that answer in minutes instead of a day
• You verify before you trust: youd catch a plausible but wrong AI suggestion before it ships
• You can operate across languages and layers without needing to be a specialist in all of them including ones you dont know yet
• You respect the promotion pipeline. You dont route around dev to test to prod because its slower

The stack youll touch:

Angular and React on the web frontend native iOS in SwiftUI a Node/TypeScript application server and Go for newer backend services a legacy Hack/HHVM core were winding down Kubernetes Helm GitLab CI Docker a Formance-based ledger WebSockets cron-driven scheduled workloads and a growing AWS serverless layer (Lambda API Gateway DynamoDB S3/CloudFront)

Youre a strong fit if..

• Youve operated real distributed systems not just built a monolith and called it done.
• Youre 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
• Youre comfortable being dropped into someone elses 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 behaves
• Youre honest about uncertainty. I dont know let me check the logs beats a confident guess from you or your AI tools

Not expected:

• Any prior Hack (or R) experience. Nobody on the team learned either on purpose and were actively phasing both out
• A portfolio of AI-free work. Were not testing whether you can code without tools were testing whether you build good software in a real system

This is a rare opportunity to build at the intersection of AI creator technology and consumer products.

WePush is backed by experienced operators from companies including Spotify Google and many more. Were entering our next phase of growth with the ambition speed and ownership of a startup but with a proven product and strong market traction.

As an AI Product Engineer you wont be sitting on the sidelines. Youll work closely with the founders and product team to turn new AI capabilities into products used by brands and creators at scale.

What we offer:

• Competitive salary and meaningful equity package
• High ownership from day one with the freedom to ship experiment and influence product direction
• Direct access to founders and leadership with fast decisions and minimal bureaucracy
• A team of builders: Ambitious pragmatic and obsessed with moving fast
• An in-person culture in our Berlin office with flexibility for home office days
• Public transport pass gym membership recurring team lunches and other perks
• A front-row seat to building a category-defining technology company

Regardless of who you are where you come from how you look or what music is playing in your headphones you are welcome.

If you are a builder and move fast this role is for you.
