About this role
Runway is a company focused on building AI to simulate the world by merging art and science. They are seeking a Trust & Safety Engineer to ensure the positive impact of their generative AI models, collaborating with product, research, and policy teams to address model safety and build necessary infrastructure.
Responsibilities:
- Serve as a core safety partner embedded across product and research teams, providing Trust & Safety engineering support for all launches - from early design review through post-launch monitoring
- Build and maintain safety infrastructure that ensures Runway's models have a positive impact on the world as they reach millions of users
- Design, execute, and continuously improve red teaming systems to proactively surface model safety issues, such as harmful content generation, filter bypasses, and policy-violating outputs, before they reach production
- Translate ambiguous, fast-evolving T&S challenges into concrete technical solutions, often without an existing playbook; comfort with navigating uncertainty and proposing novel approaches is essential
- Improve the performance, reliability, and code quality of our codebases
Requirements:
- 3+ years of experience in software engineering, with production experience in Python or TypeScript
- A proactive, ownership-oriented mindset - you'll own systems end-to-end (infrastructure, monitoring, logging, metrics, incident response) and be responsible for identifying risks, not just responding to tickets
- Comfort working across the stack - from writing model evaluation scripts to building internal tooling to debugging infrastructure issues in AWS or GCP
- Experience with data pipelines or analytics infrastructure (we use ClickHouse heavily for abuse detection and policy enforcement signals)
- Ability to translate ambiguous, fast-evolving policy requirements into concrete technical solutions - you'll often be defining the approach, not following an existing playbook
- Strong written communication skills; you'll work closely with legal, policy, and product teams to document safety decisions and explain technical tradeoffs
- Humility and open mindedness; at Runway we love to learn from one another
