BLOCKS is bringing big-company cloud efficiency to startups and SMEs. We guarantee 20% savings from day one by pooling cloud spend into a group-buying model. From there, our AI agent “Major Tom” acts like a virtual DevOps engineer, finding waste, optimizing infrastructure, all in an automated way to maximize cloud efficiency. We are building Blocks because startups deserve cloud economics that actually make sense.
Our founders (Oliver and Andreas) are serial entrepreneurs, have raised >$1 billion, and successfully sold multiple businesses.

Improve reliability and delivery workflows, contributing to CI/CD pipelines, frontend build optimizations, and quality checks that keep both web and chat clients fast and dependable
דרישות
Frontend experience: Strong experience with modern Typescript frameworks (e.g. React with NextJS), building responsive UIs with clean component architectures
Deep expertise in Python: End-to-end systems with async patterns (DI/await/async ORM); modern web frameworks (e.g., FastAPI/Django/Flask)
API integration expertise: Design/expose scalable APIs; handle AWS data/internal services with multi-tenant isolation/rate limits

Great to have: Practical experience shipping event-driven chat apps or bots (e.g., Slack Bolt SDK with OAuth, JS/TS integrations for Microsoft Teams etc.), including webhook processing and interactive UI flows
Startup execution mindset: You have shipped 0→1 products fast with high ownership, autonomy, and accountability

Direct communicator: You value clarity and feedback as tools for speed, improvement, and alignment
Demonstrated impact: You have impressive achievements from previous jobs and from side projects. Please share them with us.
What we offer
Build where AI actually matters. Real AI shipped into production that changes how companies run cloud infrastructure.
Work with founders who’ve done it before. Unicorn builders, $1B+ raised, zero politics, fast calls, radical candor. We move, not debate.
Zero to One. The opportunity to build a product which startups will consider standard infrastructure.
Real ownership, not theater. We challenge, you make calls. Some will be wrong. That’s fine. We fix fast and keep shipping.
Compensation that reflects ambition. Top market cash compensation plus meaningful equity upside.
Berlin, in person, by design. Early stage companies are built together, not on Zoom. We support relocation.
How we hire
We believe hiring should be like we build: Fast, respecting your time and ours, to the point:
Intro call with a founding team member (30 min)
Tech interview/assessment with an engineer (~60 min)
In-person case study with the founders (1-2 hours)
Offer call within 24 hours with a founder (15 min)
If you want comfort, this is not for you. If you want ownership and speed, we should talk.
