2026 PhD Software Engineering Internship, Aarhus
About the team:
Uber Denmark is the powerhouse behind the core infrastructure that runs Uber globally. We don't just build mobile apps; we build the systems that deploy and run every microservice, database, and data workload across the world. For a PhD intern, this means your research isn't destined for a shelf, it's destined for production at a scale few companies can match.
You will be embedded in a team of specialists to tackle bold, unsolved problems in computer science. As a PhD intern, you will own a project from ideation to implementation, with the explicit goal of bridging the gap between novel research and production impact. You'll work alongside a concentrated group of PhDs and engineers in Aarhus who speak your language, providing a high-caliber peer group that understands how to translate academic rigor into industry-shaping technology.
About the Role:
This role is for the PhD student who thrives in the gap between "theoretically possible" and "operationally reliable." You will join a stellar team of engineers in Aarhus, including several with PhDs, where you will solve high-stakes problems in reliability and efficiency. The challenge is real: our systems are massive, the pace is relentless, and the data is often messy. You'll need more than just technical depth; you'll need the grit to navigate ambiguity, the ownership to see a project through to implementation, and the adaptability to pivot when real-world constraints clash with your initial hypothesis. If you are motivated by seeing your algorithms and models directly impact millions of users, this is where you belong.
Example projects ( you'll focus on one primary project):
- Optimize bin packing in our dynamic environment to increase host utilization rates, reducing global infrastructure costs.
- Build a code risk scoring model that predicts the likelihood of a code change causing a production incident, helping us block high-risk changes before they land.
- Navigate the messiness of incident data to build classifiers that distinguish between true and false positive rollbacks, creating a robust dataset for automated mitigation of production failures.
- Advance the state of Cadence workflow versioning by designing "correct-by-design" systems that prevent the manual, error-prone versioning issues that currently lead to production outages.
- Apply Generative AI or static/dynamic analysis techniques to identify patterns in incident postmortems, preventing future regressions before they happen.
- Collaborate cross-functionally with teams in Reliability and Efficiency to translate complex business problems into elegant, scalable technical solutions.
- Own your research end-to-end-from initial idea and experimentation to building a prototype that works within Uber's production ecosystem.
