About Blockbrain

For mid-sized companies, knowledge is the last real competitive lever. Yet knowledge gets stuck in tools and SharePoint folders — or disappears when experts leave. While IT is still planning, employees are already using ChatGPT and the like — without governance, and sensitive data is leaking out.

With the Knowledge Bots platform, Blockbrain creates what companies truly need: AI-powered knowledge management that is quick to implement, flexibly scales, and operates in a compliant manner. Teams use our GenAI building blocks to build tailored AI assistants, agents, and workflows in minutes — just like Lego.

Series A funded with strong growth momentum (10x product usage & 5x revenue in 2025)

Enterprise clients such as Roland Berger, Bosch, IONOS , and Harting from industries including manufacturing, finance, and legal — sectors with the highest security requirements

ISO 27001 certified, EU AI Act ready. Made in Germany.

Role & Impact

You’ll work across our engineering organization. In areas like Agents, Knowledge, Enterprise, or Mobile - taking meaningful, sometimes ambiguously defined problems from understanding through implementation to production monitoring. You’ll own problems end-to-end, make technical decisions within your scope, and use coding agents as a core part of how you build. Not as a novelty, but as a multiplier for speed, quality, and technical depth.

Responsibilities

Own problems end-to-end:Understand the why before touching the code, ship robust solutions with tests and observability, and follow through in production.

Make sound technical decisions:Choose the right approach within your scope and stand behind it.

Write strong code reviews:Catch real issues such as logic errors, missing edge cases, weak abstractions, and technical debt early.

Surface risk proactively:Identify technical risks before they turn into incidents or product issues.

Collaborate cross-functionally:Work closely with Product, Design, and other Engineering teams to turn ambiguous requirements into clear solutions.

Mentor other engineers:Support Junior and Mid-Level Engineers with concrete, actionable feedback on real work.

Contribute to operational excellence:Participate in incident reviews and help turn learnings into lasting improvements.

Use AI as part of the workflow:Leverage AI tools and coding agents to structure work, accelerate implementation, and improve documentation and code quality.

Profile

Several years of experiencein product-focused software engineering, ideally in complex, distributed, or fast-moving environments.

Strong TypeScript experience:You feel at home in TypeScript monorepos and build maintainable, production-ready software.

Pragmatic Python knowledge:You use Python where it adds value.

Solid infrastructure mindset:You are comfortable with Kubernetes, containerized environments, and Infrastructure as Code.

Distributed systems thinking:You understand event-driven architectures, scalable services, and cloud-native patterns.

Production-minded:“Merged” does not mean “done” — you care about observability, reliability, and long-term maintainability.

Technically decisive and honest about complexity:You clarify unclear requirements early and communicate trade-offs clearly.

Genuinely curious about AI systems:You’re interested in agent runtimes, workflow orchestration, retrieval pipelines, and tool use — and you’re open to using AI daily as a co-pilot.
