Hivemind; San Francisco (CA); On-site; USD 180,000 - 260,000; Full time

Benefits offered by this job

Founding-team equity

Studio in downtown San Francisco

Job summary

Hivemind is building a social AI that talks to many people at once, with one-on-one conversations. We are seeking founding members of technical staff to co-own the foundation from day zero and shape the team as it grows.

You will define technical standards, build core infrastructure, and push towards shipping innovative social intelligence capabilities at scale. This role is based in San Francisco, with the founding team in a hands-on, high-ownership setup.

Qualifications

• You've shipped and scaled robust, reliable systems, and you're comfortable owning backend and infra outright.
• You've built social products, think in network effects and product outcomes.
• You've worked on scrappy, early teams or were a founder in a past life, so you value the collision between vision and reality we call "shipping."
• You're fearless inside your craft and a good student outside it.

Responsibilities

• Build fast, efficient infrastructure that enables social interaction across a large volume of users across the globe.
• Build the sourcing engine at Hivemind's core: out of thousands of people, figuring out who to ask, when, and how, so that they actually answer.
• Build and scale systems that learn continually from many users' feedback in real time.
• Ship within hard, interesting constraints: Hivemind lives in iMessage, and real-time social intelligence has to feel alive at any scale.
• Own context management, model orchestration, and systems that let one AI reason across a fractal network of relationships.
• Work across backend, AI infra, data, and devops as the work demand, going from idea to production in days, with attention to craftsmanship, quality, and reliability.
