Jobbeschreibung

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!

Tasks

As one of our first hires, you’ll play a pivotal role in shaping both our product and technical direction, working closely with the founders from day one.

You’ll enjoy true agency—owning the entire technical vision—and have the chance to develop taste by engaging directly with customers to understand what truly matters. This rare combination of ownership and insight will empower you to make a real impact.

• Own high-impact projects: Take customer-facing AI-powered features from concept to production.
• Build agentic workflows: Design and build production-ready agentic workflows that equip agents with the right steps and context to automate even the most challenging construction processes.
• Tackle challenging data: Work with some of the most complex and unstructured multimodal data you’ve encountered, and take ownership of building, improving, and scaling our data pipelines.
• Experiment with cutting-edge AI: Explore novel approaches to streamline and enhance construction management workflows.

You will be working closely with Vinzenz (CTO) and Ann (CPO) who own tech and product respectively.

Our Stack: We use TypeScript across both frontend and backend, with Next.js and Tailwind for the frontend. Our backend runs on serverless Node.js functions. For LLM chains, we leverage LangChain and LangGraph. Our infrastructure is based on Vercel and Supabase (PostgreSQL with vector embeddings). You should be familiar with a majority of these but we trust that you can pick up a new language/framework quickly.

Requirements

This is the perfect role for an experienced engineer who wants to join an early-stage company and shape the future of construction with applied AI.

• C1 fluency in German – You’ll navigate complex construction industry jargon and must be able to refine prompts or dive deep into our German data to optimize them effectively.
• You have 1+ years of experience building AI features in the OpenAI and Anthropic era—whether that's RAGs, recommendation engines, or document-filling pipelines.
• You ship fast, are comfortable wearing multiple hats, and take full ownership of your projects. When you say "I'll figure it out," we know it will get done.
• You are comfortable working across the entire stack—from building evaluation frameworks and setting up robust backend services on GCP to launching your own AI features.
• You’re eager to shape our product – whether you do it by analyzing user feedback, ramping up analytics, or championing your own ideas.
• You are self-updating, question your assumptions, and adjusting your strategies whenever you learn something new.
• You have impressive achievements from previous careers and from side projects — we’re excited to hear about these!

Bonus Points

• You’ve started a company or worked at a very early-stage startup
• You've built something where 100 lines of code replaced hours of manual work

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.
