Staff AI Engineer, Agentic Automation

Every application Cerby protects needs Cerby to know how it works - its API, or the clicks behind its login, password rotation, MFA setup, or access change - and that knowledge breaks whenever a vendor redesigns its site or changes its API. We are looking for a Staff AI Engineer to own the AI agents that onboard new applications and repair automations when they drift. You will start with two agent systems we have already built and benchmarked:

API catalog generation: reads a vendor’s public API docs in a headless browser and produces a validated OpenAPI spec, with per-job cost ceilings and an accuracy benchmark.

Browser workflow generation: performs a task in a SaaS app’s web UI and writes a replayable automation workflow, handling MFA, one-time codes, and CAPTCHAs along the way.

Your job is to take them to production, make them self-healing, and set the direction for agentic automation at Cerby. These agents handle real customer credentials and browse untrusted sites, so security is part of the job, not an afterthought.

• You have shipped an LLM agent with tool use that ran unattended for real users, and owned a backend system in production.

Technical Skills

• Strong in Python or TypeScript, and productive in both.
• LLM agents and tool use: agent loops, structured outputs, retries, and the failure modes they create.
• Eval discipline: you have built benchmarks or eval harnesses and used them to make decisions.
• Depth in browser automation (Playwright or similar) or backend and API-integration systems, and comfort in the other.
• Distributed systems: queues, idempotency, and durable workflow engines (Temporal, Step Functions, or similar).
• Security judgment for systems that handle secrets, including agent-specific threats such as prompt injection., * Temporal in production; Pydantic AI or a comparable agent framework.
• Open-weight model serving (Fireworks, Together, Bedrock) and LLM cost modeling.
• Computer-use agents or browser extensions (Chrome MV3); OpenAPI tooling.
• Identity, IAM, or credential-management experience; AWS and Terraform.

Soft Skills

• Clear technical writing and trade-offs other teams can depend on.
• You take an early system to production without waiting to be told how, and care that it keeps working after launch.

Cerby extends your security perimeter to include your disconnected applications, providing identity automation and eliminating manual processes.
