Are you a software engineer who thinks the last mile of analytics deserves better than an email with a spreadsheet attached?

Crunch builds the data-driven companies of tomorrow. Behind the scenes that means forecasts, optimization models, and AI agents. But people don't use models. People use applications. We are looking for the engineer who builds that final, decisive layer: the screen where a planner, buyer, or manager actually takes the decision.

That means treating UI, UX, and engineering as one discipline, not three departments.

As aSoftware Engineer for Analytical Applications, you build the tools our clients open every morning. Generative BI interfaces where you converse with your data instead of hunting through it. Planning cockpits where a forecast, its uncertainty, and the recommended action sit on one screen. Approval flows where a human confirms, overrides, or corrects what a model proposes, and the result flows straight back into the business process. You know that a data-intensive application lives or dies on details: perceived speed, progressive disclosure, a table that stays readable at 10,000 rows. And you can actually build those details, not just point at them in Figma.

In your role, you sit between our data scientists, AI engineers, and the client's daily reality. Your job is making the clever stuff usable.

What will be part of your responsibilities?

Design and build web applications on top of our data platforms: decision cockpits, generative BI front-ends, what-if tools;
Integrate those applications into real business processes: write-backs to ERP, approval workflows, alerts where people already work;
Make model output understandable on screen: uncertainty, confidence, and the "why" behind a recommendation, without drowning the user;
Own the full slice: front-end, API layer, and the glue to the data platform underneath;
Choose the right weight for the job: full custom build, Streamlit prototype, or low-code, and defend that choice;
Prototype fast for sales and pilots, then harden what wins into production software;
Push the whole team's bar on UX. If a first-time user needs a manual, you're not done.

Above all, you measure your work by adoption. Not by demos, not by deploys: by people choosing to open your application again tomorrow.
