Fullstack AI Engineer

Preconstruction is the foundation of every project, where the work gets chosen, priced, and put together. But while the projects have grown, the documents multiplied, and the requirements gotten heavier, the way the work gets done looks almost the same as it did decades ago.

Arctis AI is transforming how preconstruction works, making the people who run it faster, sharper, and able to take on more than ever before.

We're a small, talent-dense team out of TUM, with backgrounds spanning Bain, KPMG, SAP, Snowflake, and AWS. We're backed by PT1, EWOR, and operators and investors from European construction and tech, including the owner of PERI and partners at Atlantic Labs and La Famiglia.

As Fullstack AI/LLM Engineer
, you'll build the agentic systems behind bid comparison, clause extraction, and risk detection, on top of large volumes of unstructured construction data.

Deployments: Run each rollout end-to-end - data onboarding, agent configuration, pipeline setup, launch. When something blocks go-live, it's yours to clear.

Data & integrations: Get customer data into shape - past projects, prices, documents, sub lists and connect Arctis to the systems precon teams use.

Prototyping: Build fast prototypes that solve emerging customer problems, then work with the core team to turn the good ones into product.

Feedback loop: You'll see how the product holds up in the field before anyone else. Bring what you learn back into the roadmap - which failures repeat, which requests keep coming up, what to build next.
