Founding Engineer

ArcaLabs is hiring founding engineers to build the platform behind AI agents that perform sell-side financial workflows. The role spans agent runtime and infrastructure, evaluation and observability, secure customer deployments, and shared platform features for customer-facing teams.

Responsibilities:

• Build and own components of our agent runtime including retrieval, memory, evals, and potentially more core AI work with finetuning and RL
• Build infrastructure for our agents and agentic workflows: sandboxes, VMs, lifecycle management, security, observability, data pipelines, and more
• Work on evals and observability for our agents and agentic workflows, so that we can ship better agents faster
• Make the platform deployable in customer VPCs with single-tenant, KMS-keyed, audit-logged isolation, so that we can get inside customer networks without lighting hair on fire
• Act as a foundation for our Forward Deployed Engineers and sales teams to harden the patterns that show up across multiple customers into shared platform features
