Research Engineer - AI Research Team

About Metamorphic

Metamorphic is developing new approaches to intelligence by combining machine learning with large-scale experimental neuroscience, informed by the principles that make the brain efficient, flexible, and robust. We are building foundation models trained on rich, continuous neural data — a high-resolution model of the brain at a scale never before possible.

Our founding team spans machine learning, neuroscience, and neurotechnology, with prior work including the MICrONS project, Neuropixels, and the Enigma project, as well as foundational scientific contributions in learning, neural computation, and generative modeling. Our work sits at the frontier of AI research, and we believe the highest-impact discoveries will come from researchers and engineers working as a single, tightly collaborative team.

The name Metamorphic reflects our belief that the next advances in intelligence will come from a change in form, beyond scale — from artificial to natural intelligence.

About The Role

We are seeking Research Engineers to join our growing AI research team. You will work on building and scaling state-of-the-art large language models that power Metamorphic’s next generation of foundation models. This is a high-impact, technically deep role working at the frontier of ML research and engineering. In this role you will interact with many parts of the research and engineering stack, from model architecture and pretraining to evaluation, tooling, and infrastructure. you will design data annotation and evaluation pipelines, run large-scale experiments, and build tooling that accelerates research in service of pushing the quality and scale of our language and multimodal models. You'll have substantial autonomy to shape foundational technical decisions on a small, high-impact team.

You'll Thrive In This Role If You

• Have significant software engineering experience and can move quickly without sacrificing rigor
• Are able to balance research goals with practical engineering constraints
• Are happy to take on tasks outside your job description to support the team
• Enjoy pair programming and deeply collaborative work
• Are eager to learn more about machine learning research in a novel scientific domain
