Nice to Have * Custom agent runtimes or orchestration frameworks; agentic coding systems or autonomous development environments. * Persistent or hierarchical agent memory, context engineering, retrieval architectures, or long-running agent workflows. * Secure code execution, sandboxing, Docker, Kubernetes, microVMs, or ephemeral compute. * Multi-agent coordination, MCP servers, tool registries, capability-based permissions, model routing, or agent evaluation and tracing. * Enterprise SaaS, M&A, virtual data rooms, regulated data, financial services, or complex document-centric workflows. ## Description * Lead the architecture and evolution of Datasite's custom agent harness, including reasoning and execution loops, planning, tool selection, state transitions, structured outputs, and runtime controls. * Design layered agent memory spanning working context, episodic history, semantic knowledge, and durable workflow state; build retrieval, consolidation, compaction, provenance, retention, and access controls. * Architect isolated, containerized agent execution environments for code, files, and tools, with ephemeral workloads, tenant boundaries, resource quotas, restricted networking, and secure credential handling. * Build resilient agent orchestration: asynchronous tasks, specialized subagents, delegation, checkpoints, resumability, retries, failure recovery, and human approvals. * Create secure, extensible tool integrations using MCP and related interfaces, with authentication, authorization, least-privilege permissions, and safeguards against prompt injection and unsafe actions. * Establish agent evaluation, tracing, observability, and regression testing to measure task quality, correctness, reliability, latency, and cost; drive measurable improvements * Make high-impact technical tradeoffs between probabilistic model behavior and deterministic application logic, validation, or human review. * Partner with Product, Machine Learning, Security, and platform teams to turn diligence, research, and deal workflows into production-grade agent experiences; mentor engineers while remaining hands-on in critical implementation.
