Why QuantumSpring
Build with people who care about craft and delivery.
We combine product thinking, rigorous engineering, and AI-native workflows. If you like moving fast without sacrificing quality, you'll fit in.
AI-native delivery
Ship with an advanced AI toolchain, autonomy patterns, and engineers who know how to keep quality high while moving fast.
Small, senior teams
Work with peers who own the whole lifecycle — discovery, build, launch, and iteration — without layers of management.
Real production impact
We build AI systems that ship to customers, not just demos. You will see your work used in production quickly.
Prague base, remote friendly
Core team in Prague with flexibility across Europe. We gather frequently for build weeks and client launches.
How we work
Clear ownership, strong tools, and bias to action.
Our rituals are lightweight. We align quickly, build, and iterate with customers. You'll have autonomy to choose the right implementation while staying close to the outcome.
Ownership over tickets
We expect engineers and designers to shape the solution, not just implement tasks. Clear ownership beats long meetings.
Bias to shipping
We prototype early, validate with customers, then harden. Every sprint ends with something tangible in users’ hands.
Tooling obsessed
Cursor, Claude Code, custom scripts, and automation to remove toil. We continuously refine our stack to stay fast.
Direct communication
No politics. Straight feedback, lightweight rituals, and written context to keep everyone aligned.
