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 complete technical ownership of our product, working directly with founders to build a category-defining platform from the ground up.

You'll enjoy true end-to-end ownership —from database architecture to user interface—and direct customer impact by shipping features that solve real problems for an industry ripe for disruption.

• Own the full product experience: Build customer-facing features from database design through beautiful, responsive frontends that users actually love using.

• Architect for scale: Design robust, scalable systems that handle complex workflows and large datasets while maintaining excellent performance and developer experience.

Why this role is different:

• Complete technical autonomy to choose technologies and approaches

• Direct founder collaboration on product and technical vision

• Modern, best-in-class stack chosen for developer happiness and velocity

You will be working closely with Vinzenz (CTO) and Ann (CPO) who prioritize developer experience over premature optimization.

We prioritize speed: instant deploys, no infra headaches, and developer velocity over cost. AI is baked into everything—engineers spend above €500 per month for AI tools like Cursor Background-Agents and Claude Code. Our product teams handles small features and fixes with AI agents, leaving you only the hard problems.

Our stack at a glance: TypeScript, Next.js, Vercel, Supabase (PostgreSQL + vectors), LangChain, TanStack Query, shadcn

Qualifikation

This is the perfect role for a full-stack engineer who wants to join an early-stage company and build a product that transforms how an entire industry operates.

Must-Haves:

Bonus Points:

• Previous startup experience – especially early employees who wore multiple hats

• Domain experience in construction, manufacturing, or complex B2B workflows

• Strong design sense – can create clean, usable interfaces without needing detailed mockups

• Experience in integrating AI – comfortable working alongside AI features, even if you're not building the AI itself

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.

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.
