About the role
We're looking for a Founding Engineer to own core pieces of our agent runtime and developer/product surface area. You'll build the systems that let agents operate safely, deterministically, and measurably in production: memory + context management, tool integration, sandbox execution, data syncing, evals, and AI-native UX.
This is a hands-on role where you'll ship to production quickly, work directly with design partners, and help define what "good" looks like for enterprise-grade agents.
What you'll own
Agent runtime + orchestration
- Agent loop design (planning → tool-use → verification → recovery) with strong guardrails.
- Context assembly pipelines: retrieval + compression + summarization + "state" that survives long workflows.
- Memory management: short-term working memory, long-term memory, user/org/project memory, and safe write policies.
- Multi-agent patterns: delegation, handoffs, coordinator/worker setups, and concurrency.
Tooling + integrations
- Tool definition frameworks: typed schemas, validation, retries, idempotency, rate limits, and observability.
- Connectors + data syncing: SaaS APIs, webhooks, polling strategies, incremental sync, conflict resolution.
- Browser automation / computer-use flows (auth, session handling, DOM variability, screenshots, network traces).
Sandbox + execution
- Secure execution environments for "agent writes code / runs scripts / transforms data."
- Permissions, isolation, secret management, and audit trails.
