Senior Software Engineer - Web (f/m/d)

Mission At Bliro, we're transforming how businesses capture and leverage customer interactions with privacy and AI at the core. We're extending our small, elite team of engineers who will define our technical foundation and shape a product used by leading businesses across Europe. As a Senior Full-Stack Engineer, you'll own critical systems end-to-end from the React frontend to the Node.js backend and everything in between. You won't just write features. You'll design the architecture that lets us move fast at scale, ship AI-powered workflows that actually work, and build the engineering culture from the ground up. From the start, you'll lead technical initiatives. This is a role with real impact on how we build. What You'll Do Own systems, not tickets. Take full responsibility for major product areas from database schema to deployment pipeline. You scope, build, ship, and iterate. Build AI-native product experiences. Design and implement the backend services and frontend interfaces that power Bliro's personal AI assistant - real-time transcription, intelligent summaries, automated CRM syncs, and agentic workflows. Set the technical bar. Help us establish patterns, conventions, and guardrails that the engineering team will build on. Ship across the stack. Work in TypeScript/React on the frontend, Node.js on the backend, MongoDB for persistence, and Azure for infrastructure. You're comfortable in most areas in this stack. Lead by example. Drive architectural decisions in code reviews, and create a culture where quality and velocity aren't trade-offs. What You Bring Must-haves: Strong computer science fundamentals from a top-tier university (TUM, ETH, RWTH, KIT, or equivalent) 3-5 years of hands-on full-stack experience with TypeScript, React, and Node.js Deep understanding of MongoDB or similar document databases at scale Experience designing and operating production backend systems Track record of owning and shipping complex features end-to-end, ideally in a startup or as a technical co-founder Strong opinions on code quality, testing, and system design - loosely held Nice-to-haves: Experience building or scaling your own product (side project, startup, open-source) Previous CTO, tech lead, or founding engineer role Familiarity with LLM integration patterns such as prompt engineering, structured outputs, agent architectures Electron or desktop app development experience Azure or AWS infrastructure experience (serverless, container apps, CI/CD) Understanding of compliance requirements (SOC 2, ISO 27001, GDPR) in production systems Why Bliro Real ownership from day one. No ticket factories. You pick up problems, not tasks, and you own them until they're solved. Technical depth meets product impact. You're not building internal tooling. Every line of code ships to paying customers and directly moves the business. Elite, small team. 10 engineers, seed-stage, Munich-based. Everyone knows everyone. No layers, no politics. Leadership trajectory. Step into a technical leadership role early on. Define how we build, not just what we build. All inclusive package. Experience various company benefits including VSOP participation so you benefit directly from the company's success.
