Backend Engineer

SLAY, founded in December 2022, has swiftly made its mark in the mobile world. The company developed 5 apps and games that reached the #1 spot in the App Store across 3 continents.

Backed by some of the world's most esteemed investors, including Accel, Kevin Weil, Riccardo Zacconi, Scott Belsky, and Ilkka Paananen, SLAY is rapidly growing and reaching millions of users.

Our mission is to create digital life through AI and become the leading company for virtual friends that live, grow and evolve like humans—starting with Pengu. Pengu has become the biggest AI character app with its own IP in the US and Europe.

• In-person working (Berlin). No remote/hybrid.


• A-players only. Only A-players can hire A-players. We’d rather hire 1 A-player and pay an above-market amount (that someone is very happy with) than hire 3 B-players and pay market.


• Drive. You’re hungry to do what it takes for us to win. You likely have a massive chip on the shoulder and/or a neurodivergent brain. Work is a key part of your identity / fulfillment in life.


• Grind. We work/text on weekends and at night. It’s ok to send messages at 3am.


• Urgency. Do in a day what usually takes weeks. Run through walls to get things done. Respond in minutes (or seconds) instead of hours.


• Relentless. Winning comes first. Check-in frequently, double or quadruple-text, call repeatedly if needed.


• Fast firing. If someone isn’t an A player, we part ways quickly. Please be okay with this. We do paid trials to help derisk this.


• Mission-driven. “Help people resonate” as a mission sounds fun to you.


• Wear many hats. No job is not your job.


• EV-based decision making. No buying IBM because it’s safe.


• User-first, not team-first. It’s our job to make things move fast. We dropped the ball if a user feels like we did.


• Flat company org. Titles reflect scope. No political promotion games.

• Having product sense is great


• No product managers


• NestJS (NodeJS / Typescript), AWS / GCP, Redis, Postgres


• 0-1, early stage eng experience is great

• Salary: You'll earn more than in your previous job.
