The role

As MLOps Engineer youll join our tight-knit machine learning team working on psychology foundation models.

Our models have real-world impact so this is a pragmatic high-impact role. We ship a lot. Youll be able to work at a faster pace than almost anywhere else while writing high-quality code and producing meaningful scientific insights. We have a rich and growing dataset and constantly run experiments to find the best way to use it to improve our models. Some of our current work includes data collection curation continued pre-training ablation studies creating synthetic datasets supervising the creation of hand-crafted data preference optimisation training reward models and state-of-the-art reinforcement learning research.

As MLOps Engineer youll be responsible for ensuring that our data pipelines model training setup and model serving infrastructure work together smoothly. Youll also contribute to our end-user product improving user experience through your work on our models and model orchestration.

Youll be working with the latest open-source language models as well as frontier models through our deep partnerships with the largest AI labs. Youll read papers and identify state-of-the-art techniques for us to learn from and contribute to our core ML research.

We write high-quality typed Zen code mostly in Python. Our application backend is written in Kotlin and our ML stack utilizes modern tooling in the ML space including some that weve developed in-house (React/Typescript).

About you:

• Experience applying deep learning frameworks (PyTorch/TensorFlow/JAX) in production including model deployment monitoring and lifecycle management.

• Experience training and adapting open-source language models with a strong focus on dataset pipelines reproducible environments and scalable training workflows.

• Solid software engineering fundamentals ideally with experience in at least one non-Python language and an understanding of modern service architectures and distributed systems.

• Able to clearly explain complex ML and MLOps concepts to non-technical stakeholders.

• Enjoy a fast-paced environment and make pragmatic decisions. Ultimately youd rather prove out an idea through quick MVP code than present a slide deck to explain it.

• Understand and appreciate that deep learning is magic!

Key responsibilities:

• Build and maintain scalable training and evaluation pipelines ensuring data quality reproducibility and smooth operation across GPU clusters.

• Design implement and run eval systems to measure model performance detect regressions and automate benchmarking before models reach production.

• Develop and operate the infrastructure powering model training and inference improving reliability throughput and cost efficiency.

• Stay current with SOTA ML research and identify techniques that can be integrated into robust production workflows.

• Contribute across the stack when necessary helping integrate new models tooling and ML capabilities into the product from prototype to production deployment.

What we offer:

• A chance to join a passionate tight-knit team working on something to change the world

• Competitive compensation (we target 90th percentile)

• Travel between our NYC / London offices

• Usual startup perks like free lunch in our offices generous learning budget

• Generous budget to cover your personal therapy
