These core values are fundamental to us — as individuals and as a team.

LVL 01

Sustain­ability

So you can invest in your personal growth for years to come — rather than a short sprint to level up and burn out.

LVL 02

Deep mastery

So you can seek consistent, incremental improvement in the areas you want to become an expert at.

LVL 03

Playful creativity

So you constantly try new things, even tiny ones. Doing things for the first time lets us test new areas for growth — and builds our capacity for failure.

LVL 04

Raw happiness

So you feel excited arriving at work, in a safe and supportive environment. Positivity, empathy and happiness are skills worth learning.

LVL 05

Authen­ticity

So you feel the direct impact of what you do on the business, while acting on what feels right to you. By being who we are, we escape competition — doing what we do best, and love, for the long run.

LVL 06

Teamwork & collaboration

So you know someone else has your back. We celebrate differences and synergies — and push for them.

$ git push origin culture/main

min(bureaucracy), max(ownership).

Nine principles we actually ship by. Each one rolls out like any change here: through a pull request, straight to production. Watch the aisle light up, or ship one yourself.

autonomy with min(bureaucracy)

Small teams, big mandates. We keep process light so engineers can move fast and own their calls.

  1. Small teams, big mandates. We keep process light so engineers can move fast and own their calls.
  2. You own it end to end, production included — and you can move between domains as your curiosity does.
  3. We try new tools, question old assumptions and share what we find — in design reviews, at meetups and on our blog.
  4. Take the initiative and course-correct fast, rather than waiting for permission.
  5. Coding agents, MCP-connected tools and LLM evaluations are part of how our teams build, every day.
  6. Infrastructure as code and GitOps: every change reviewable, reproducible and reversible — through a pull request.
  7. We fix root causes, automate the toil and rehearse with competitive game days.
  8. Resilient distributed systems for the world’s largest brands, where being down — or even slow — is not an option.
  9. The bar we hold ourselves to — in the code, in reviews and in every conversation.

Everything as code. All the good toys.

We run on AWS with immutable infrastructure — and pick the right tool for every job, from JVM hot paths and real-time streams to production AI agents.
