Construction doesn't buy "AI". It buys answers it can act on, and an answer can look completely plausible while being wrong in the way that costs money on a real project. The Construction Evaluation Engineer role exists to catch exactly that: to define what great looks like for our agents, find where they fail, and turn that judgment into something our systems can measure.

It starts hands-on and close to the data, and gets more technical as you grow, from evaluating outputs to owning eval pipelines, graders and datasets. You'll work alongside our forward deployed engineers, design partners and construction experts. Evaluation here happens close to the customer.

What you'll do

• Run our agents against real construction workflows and judge the outputs on correctness, completeness and practical usefulness
• Turn real workflows, edge cases and production failures into repeatable eval cases: reference outputs, scoring rubrics, failure taxonomies and expert-reviewed datasets
• Grow into the systems around the work - eval harnesses, automated graders, regression tests, model comparisons
• Work out what genuinely needs human judgment, then engineer the rest away
• Capture what we learn from customers, experts and agent failures so every deployment improves the underlying system

You might be a fit if

• You have real exposure to construction, engineering, project planning, estimating or surveying
• You're strongly quantitative and analytical, with a serious interest in modern AI systems
• You're extremely detail-oriented - you can work through hundreds of cases without letting the quality bar drift
• You're curious about why systems fail, not just whether they fail
• You have an instinct for automation: understand the manual workflow first, then build the system around it
• You have high ownership
• You speak Swedish and English

You don't need to already be an experienced AI engineer. But you do need the raw ingredients to become one.

The practical details

Part-time to start, roughly 15–20 hours per week, flexible on how they're distributed. Hybrid with meaningful time at the office at Linnégatan 89B, Stockholm.
