Senior Applied Research Engineer

Zep is the memory and context layer for AI agents. As a Senior Applied Research Engineer, you'll explore novel approaches to memory, context, and context generation, then own those ideas all the way to production.

This is a research role with a hard applied bent. We're not hiring ML researchers chasing publications. We're hiring engineers who can run rigorous experiments, train and evaluate models, and ship the result as production code our customers depend on.

What you'll do

• Explore novel approaches to memory, context, and context generation. Define the problem, run the experiments, ship the result.
• Own research to production end-to-end: dataset creation and curation, experiment design, evaluation, training and finetuning, and production deployment.
• Train, finetune, and evaluate models on Zep's domain. Build the eval harnesses that catch regressions before they ship.
• Work with our model serving stack to operate inference at low latency and reasonable cost on AWS.

What we're looking for

• 6+ years of production engineering with a strong backend systems background. You've shipped services with real throughput and latency requirements.
• Master's in Computer Science or equivalent.
• Strong research skills: methodology, dataset creation and curation, experiment design, and evaluation. You can frame an open problem and design experiments that actually answer the question.
• Hands-on experience with model finetuning. Working familiarity with transformer architectures, training and finetuning workflows, and evaluation. PyTorch and OpenAI Triton for experimentation.
