**Location:** Unspecified
**Role:** ML Engineering
**Skills:** TypeScript, Rust, Workers, Durable Objects, Kv, R2, D1, Postgres, Vectorize, Workers Ai, Ai Gateway, Agent Sdk, LLMs, Prompt Engineering, Evals
**Posted:** 2026-07-15

> Build and ship production AI agents on Cloudflare's edge platform using Workers, Durable Objects, and AI tools. Requires strong TypeScript/Rust experience, observability expertise, and hands-on LLM tooling for evals, safety, and multi-agent systems.

## Job Description

## What You Will Do
- Build agents on Workers with Durable Objects for state and short term memory
- Wire tools with the Agent SDK, MCP, and function calling
- Use Vectorize, KV, R2, and D1 for semantic memory, cache, files, and config
- Run models through Workers AI and AI Gateway; integrate third parties when needed
- Create evals, guardrails, and audits. Measure, tune, re-ship fast
- Build agents that summarize, propose fixes, and escalate cleanly to humans
- Expose agent health and metrics in transparent dashboards
- Integrate with queues and webhooks; publish events on Queues or Pub/Sub
- Cut cost per case and time to first response. Prove it with data.
- Take end to end ownership including on call for what you ship (with team support)
- Design and maintain robust observability for distributed AI workflows, implementing structured logging and end-to-end tracing across async service boundaries
- Architect security boundaries for agent-led operations; implementing secure credential handling, multi-layer approval gates, and fine-grained trust scoping for mutative actions.

## Must Have
- Demonstrated success shipping production systems. Repos and releases that show real work.
- Strong in TypeScript or Rust on Workers. HTTP, queues, async, performance
- Fluency with Durable Objects, KV or R2, and either D1 or Postgres
- Hands on with model tooling. Prompt I/O, tool calling, evals, safety checks
- Observability mindset. Logs, traces, metrics, redlines
- Experience with a2a/multi-agent frameworks
- Experience developing LLM evaluation frameworks; automated scoring systems, CI-integrated quality gates.
- Bias for simple, scalable designs

## Nice to Have
- Workers AI, AI Gateway, and Vectorize in production
- Salesforce or Service Cloud experience. Webhooks and case APIs
- Security depth. Prompt injection protection, secrets detection, PII handling
- OSS agent frameworks. Know what to borrow and what to throw away.
