About Lab0

AI FDEs to make your B2B SaaS Go Live in Days, not Months

Tech

Tech at Lab0 - Go backend and React frontend - GCP as the primary cloud - A customized Google ADK agent harness - A Bifrost-powered LLM gateway - Models from Anthropic, OpenAI, and Gemini - SaaS, self-hosted, on-prem, and air-gapped deployments We have millions in API credits and expect our engineers to use agents heavily in their own work. What we're working on Enterprise platforms were built for people, not agents. Our work includes: - Building agent-safe CLIs, connectors, API wrappers, and browser automation - Limiting the impact of mistakes in production systems Adding dry runs, snapshots, restore tools, and compensating actions where native undo does not exist - Building audit trails that fit customer change-management processes - Managing shared agent memory, including versioning, conflicts, and provenance - Creating evaluation systems without an established ground truth - Running low-latency voice agents across Zoom, Teams, and Meet - Supporting cloud, on-prem, and offline environments with different models and infrastructure - Defending against prompt injection with restricted identities and tool allowlists

The role

### What you will do* Own difficult problems from prototype through production, including the agent loop, backend, and infrastructure.* Build agent-facing CLIs, connectors, idempotent API wrappers, and browser automation for enterprise platforms.* Improve tool design, context management, guardrails, and evaluation loops.* Own deployments across SaaS, self-hosted, on-prem, and air-gapped environments, including model routing, IAM, and upgrades.* Work directly with live customer implementations where agent actions have real consequences.* Use agents to build agents. We expect you to use them heavily instead of defaulting to manual work.### Who we're looking forYou are a strong generalist who has gone deep in backend engineering, infrastructure, ML systems, or another demanding technical area.You already use agents heavily and have clear opinions about harnesses, evaluation, and context engineering. When documentation is incomplete, you would rather inspect the network traffic than guess.Unfamiliar systems do not put you off. ABAP and X++ look like puzzles to solve. You think about injection, permissions, audit trails, and blast radius before something reaches production.You have high agency, low ego, and can work through the ambiguity of early-stage 0→1 development.Experience with SAP, Salesforce, NetSuite, D365, real-time voice systems, on-prem or air-gapped deployments, govtech, banking, defense, or founding and early-stage roles is a bonus.
