Meet the team behind this journey
Research Tooling Team’s mission is to provide the tooling, services and workflows that enable our researchers to build and train cutting-edge AI models. Our services include large-scale compute & processing orchestration, managing CI/CD pipelines for our ML code base, and providing tooling and workflows for overall research productivity. We collaborate closely with technical researchers, ML & HPC Engineers and Platform teams to run thousands of model training jobs per day on one of the largest NVIDIA super compute infrastructure in Europe.
Your responsibilities
Design and build full-stack features: You will own problems end-to-end, collaborating closely with our researchers to design, build and deliver tooling for efficient research workflows.
Maintain and Improve Systems: Build and maintain CI/CD pipelines for our ML code base and manage service deployments to ensure fast, safe, and reliable releases
Operational Excellence: Improve observability, monitoring and automation to proactively detect and resolve incidents
Ensure code quality and clarity: You’ll participate in thoughtful code reviews, contribute to architectural decisions, and help raise the bar for engineering excellence across the team
Collaborate cross-functionally: You’ll work closely with researchers, ML engineers and platform teams to ensure we’re solving the right problems and delivering real value to our users
Qualities we look for
Deep empathy for solving user problems and bringing a product-oriented mindset toward internal tools, balancing technical excellence with usability, adoption and measurable impact
Strong software engineering skills - clean abstractions, robust data modeling, sound architectural decisions, and ability to make things scale.
Comfortable working across the stack, even if your strengths lean more towards backend, frontend or infrastructure. Our tech stack includes Python, FastAPI, React, PostgreSQL, and Kubernetes. We do not expect a one-to-one match with these technologies.
Technical leadership, driving cross-team initiatives, mentoring peers, and setting engineering standards.
Clear communicator, active listener, and team player. You thrive in a collaborative environment and welcome feedback.
Eager to learn, open to new challenges, and not afraid to work with unfamiliar languages or tools when the problem demands it.
