Senior Full Stack Engineer; m​/f​/d

Build the software that runs a construction business.

VARM is a technology company  run insulation operations at scale, from the first customer contact to the finished installation, and we are building an AI system that runs every process behind it. Today, people make the decisions and the system does the work around them. As we scale, the system takes on more.

We built that for ourselves. Now we are building it for everyone else in European trade.

You’ll own Blue, our platform for external construction and craft businesses: the software that lets them run their core business on autopilot. It started as our partner portal and has grown into B2B software. You’ll turn it into a product that scales.

No tickets, no PM in between. You talk to the businesses using it, decide what gets built, design it and ship it.

You’ll own a product, not just a codebase.

You have 5+ years of experience building and shipping real software products, ideally in a VC-funded startup or similarly fast-moving environment.

You are strong across the stack, including Type Script, modern frontend frameworks, backend systems, APIs and SQL.

You have integrated AI into production software, whether LLM APIs, RAG, agents or similar, and understand what it takes to make it reliable for real users.

You take ownership from idea to production and don't wait for detailed specs.

You are product-minded, enjoy talking to users and can turn ambiguous problems into simple, working solutions.

You actively use AI and agentic coding to develop faster, but still care about code quality, architecture and knowing when not to use an LLM.

You are comfortable making technical decisions independently and designing reliable systems that can scale and drive business impact.

Experience in B2B products, marketplaces or operations-heavy environments such as field services, construction or logistics.

Working proficiency in German is a plus, since many of the businesses you build for speak German.
