About the Company/Team

Beget is a personal digital-twin platform that constructs a persistent, behaviorally grounded model of an individual using multi-modal signals: communications, decisions, schedules, interaction traces, and workflow patterns. This model functions as a policy-bounded autonomous agent, capable of generating actions, recommendations, and responses that reflect the user’s cognitive style, preferences, and operational heuristics. Instead of isolated copilots relearning the user in every application, Beget provides a unified, user-centric intelligence substrate, a portable digital self that can be queried, simulated, and safely delegated to across domains.

About the Role

You will be responsible for co-creating the core of Beget: Building the representation model of the digital self (behavior, preferences, heuristics). Designing and implementing the identity engine: ingestion pipelines, long-term memory, and personalization layers. Architecting the delegation + policy layer that controls what a user’s Beget can do on their behalf. Designing scalable APIs for third-party tools to interact with each user’s digital self. Shipping early prototypes to validate the UX and technical foundations. Making foundational choices around architecture, data governance, security, and compute strategy. This is not a “build a chatbot” role, it’s creating a trusted, responsible, personal digital-twin infrastructure that can support real users at scale.

Beget gives you the chance to work at the frontier of AI identity, building a persistent, trusted digital self that can think and act alongside real people. They’ll work on problems top research labs are exploring, contribute to foundational system design, and ship product features that directly shape the future of human-AI interaction. This is a hands-on, high-impact opportunity to influence a new category of technology at the earliest stage.
