Job description

ABOUT BLOCKIT Time is the the most valuable resource we have, yet coordinating it remains stuck in the dark ages. At Blockit, we're building the AI that finally fixes this: an autonomous time agent that handles the full complexity of scheduling—timezones, group coordination, in-person logistics—like an executive assistant that never sleeps. While every LLM application to date has been a one-on-one conversation, Blockit is one of the first multiplayer, stateful AI agents—coordinating between multiple people, maintaining context across conversations, and taking real actions in the world. As more people connect their calendars, our network becomes exponentially more powerful. This is the foundation of a platform of AI agents with access to the world's time. We're backed by Sequoia, and we're a small, sharp team that moves fast, ships constantly, and holds a high bar. If you want to build something genuinely new, we'd love to talk. You can visit our teams page notion.so to learn more about our team and culture! THE ROLE You'll expand what Blockit can do and where it shows up in people's lives. This isn't traditional growth engineering, it's about building new agent capabilities, opening up new surfaces (Slack, mobile, desktop, etc.), and finding ways for Blockit to handle workflows we don't support yet. You'll ship features end-to-end: talking to users, prototyping, building, and measuring. The work spans frontend, backend, and agent engineering. WHAT YOU’LL DO - Build new features end-to-end: backend, frontend, and agent integrations - Add new tools and capabilities to our agents to handle new workflows - Build and improve integrations with external services (Slack, email, calendar providers) - Collaborate with design and GTM to figure out what's missing and what's broken for our users - Prototype quickly, ship, and iterate based on what you learn - Work across the codebase—you'll touch a lot of different systems WHAT WE’RE LOOKING FOR - 2+ years of industry experience shipping production software - Ability to work across the stack as needed - Product sense: you care about UX, correctness, and clarity, not just passing tests - Pragmatic approach to building: you validate quickly, then harden what works - Clear communicator—written and verbal. You'll be working across eng, design, and users LOCATION - San Francisco, CA. On‑site 4 days per week
