Join the Fulcra Team

Why work here

Who we are

Fulcra Dynamics is building the future of agent memory, starting with Context, the personal data platform that aggregates health, fitness, nutrition, and lifestyle data from every wearable and app — then makes it actionable through AI-powered insights and a personal MCP server. We're a small, senior team of engineers, designers, and operators who previously built HUMAN Security (a cybersecurity unicorn), led product at major tech companies, and pioneered AI applications for personal data. We work remotely, move fast, and care deeply about data ownership and user privacy. At Fulcra, you'll work on hard problems at the intersection of personal data, AI agents, and health optimization. You'll ship features that real users depend on every day — from wearable integrations and data pipelines to LLM-powered analysis and native iOS experiences. We value clear thinking, strong ownership, and a bias toward building. If you want to work on something that matters — helping people actually understand and use the data their lives are already creating — we'd love to hear from you.
