AI Engineer (Founding Team)

The construction industry loses $1.6 trillion annually to inefficiencies. A huge part? Repeating the same mistakes over and over because critical information is still stuck in paperwork and scattered systems.

alago fixes this by putting existing data to work, instead of letting documentation gather dust. We help teams eliminate double data entry and manual busywork by connecting to existing tools, processing project data, and automating workflows between people and AI. With every project, alago gets more powerful —spotting risks and turning past challenges into future wins.

We’ve just raised a seven-figure pre-seed led by top construction tech VCs and one of Germany’s largest project developers. 75% of the infrastructure that will exist in 2050 does not exist today . Let’s build it better!

Aufgaben

As one of our first hires, you'll have unprecedented technical autonomy to architect novel AI systems from the ground up, working directly with founders who understand that breakthrough AI requires both deep technical expertise and creative freedom.

You'll be solving genuinely hard AI problems that don't have established solutions—the kind that require reading papers, prototyping novel approaches, and pushing the boundaries of what's possible in production systems.

• Design novel AI architectures: Build production agentic systems that go far beyond simple LLM wrappers—create sophisticated multi-agent workflows with custom reasoning, memory, and tool-use patterns.
• Push the limits of multimodal AI: Work with some of the most challenging unstructured data you've encountered (construction documents, images…) and develop novel approaches to extract structured insights at scale.
• Own the full research-to-production pipeline: From experimenting with cutting-edge techniques to building robust evaluation frameworks to optimizing inference at scale—you control the entire technical journey.
• Build AI-first infrastructure: Design and implement novel data pipelines, vector architectures, and evaluation systems that enable rapid experimentation while maintaining production reliability.

What makes this role unique:

• $500+/month AI budget for experimentation with latest models and techniques
• Direct customer feedback loop to validate AI performance in real-world scenarios
• No legacy constraints —green field opportunity to implement state-of-the-art approaches
• Research freedom to explore and implement novel techniques from recent papers

You'll be working closely with Vinzenz (CTO) and Ann (CPO) - both technical founders who understand that great AI requires both deep technical investment and product intuition.

Qualifikation

This is the perfect role for an AI engineer who wants to join an early-stage company and push the boundaries of what's possible with AI in construction.

Must-Haves:

• C1 fluency in German – You'll work with complex construction industry data and need to understand domain nuances to build effective AI systems that actually solve real problems.
• 2+ years building production AI systems – You've shipped AI features that real users depend on, not just experimented with APIs. You understand the gap between "demo magic" and production reliability.
• TypeScript proficiency – When your AI system needs a frontend interface or API integration, you can build it without waiting for other team members.
• Shipping velocity – You prototype fast, measure everything, and iterate based on real user feedback . When you say "I'll build an AI feature to solve this," it ships within days, not months.

Bonus Points:

• Previous startup experience – especially if you were the "AI person" who had to figure everything out
• Domain expertise in construction, manufacturing, or other complex industries with messy data
• Open source contributions or impressive side projects in AI/ML
• You've built AI systems that replaced hours of manual work – show us the impact

Benefits

As one of our first hires, you’ll do more than contribute — you’ll help shape how Alago works: our culture, systems, and growth strategy. You’ll work directly with the founders, gain exposure to every function, and ship projects that have immediate impact.

• 10× Learning Curve. Work with cutting-edge AI to tackle real-world challenges every day
• You ship fast and own the outcome. You’ll design solutions that take the pain out of project management, automating away the repetitive tasks and overhead teams hate.
• Work directly with the founders. You’ll own critical parts of alago end-to-end, laying the technical foundation while balancing rapid iteration, customer value, and long-term scalability.
• A vibrant in-office culture in our central Munich office . We come together in our Munich office at least three days a week. Beyond that, you’re welcome to work remotely for a few weeks at a time whenever your circumstances or preferences require it.
• Competitive salary & meaningful equity stake , so you are invested in our success
• Your needs and well-being matter to us . You’ll get access to sponsored EGYM Wellpass to find inner peace at yoga or kill it at HIIT workouts.

We’re building for scale — but right now, it’s still early. That means lots of autonomy, tight feedback loops, and the freedom to grow into whatever role suits your strengths, whether that’s become top individual contributor or stepping into leadership roles like VP Engineering.
