Job summary

Thinking Machines Lab is seeking a Safety Operations Lead to embed safety by default while enabling fast product iteration. You will triage content flags, design safety policy, and build tooling to accelerate casework, partnering with product, security, and legal teams.

You’ll influence product safety across the stack, from model refusals to abuse detection, ensuring scalable protections in a cutting-edge AI environment.

Qualifications

• 7+ years in operational trust & safety, content moderation, or fraud/abuse ops with direct, recurring case-queue responsibility.
• Experience owning policy definition, operationalization, and enforcement end-to-end.
• Direct case experience with cybersecurity abuse, CBRN-relevant risk, youth safety, or prompt injection in production.
• Familiarity with model safety and abuse risk categories and mitigation in live products.
• Experience using AI tools (Claude, Codex, or similar) to build or accelerate operational workflows.

Responsibilities

• Review flagged content, safety escalations, and account-level abuse signals daily; triage cases, apply policy judgment, and take action (flags, bans) ongoing.
• Design and refine safety policy across the product stack based on casework, collaborating with engineering, legal, safety research, and security.
• Build and maintain tooling and automation to speed up casework and ensure consistency (triage workflows, ban/recovery).
• Partner with product teams to embed safety into the product experience (model refusals, content flagging, account review, protections).
• Improve observability and detection for safety-relevant events so the next round of cases surfaces faster with better signal.
