Machine Learning Engineer

Why MemoryBox

AI should start with the person using it. Their memories, context, and ideas should shape the experience—and remain theirs.

Help us build toward that future. At MemoryBox, our ambition is to make AI feel more personal, useful, and unmistakably human.

About the role

You’ll turn personal memory into signal: retrieval, ranking, and evaluation that make every AI answer more relevant without ever leaving the user’s control.

What you’ll do

• Design and evaluate retrieval and ranking over personal memory.
• Build datasets and metrics that measure real usefulness.
• Work with the product team to turn research into shipped features.
• Keep models honest about privacy, cost, and latency.
• Share what you learn so the whole team gets sharper.

What you’ll bring

• Hands-on experience with retrieval, embeddings, or LLM applications.
• Comfort moving between experiments and production code.
• A habit of measuring before believing.
• Interest in human-centered, privacy-preserving AI.
• Clear writing and a collaborative mindset.
