runway-ml - Member of Technical Staff, Trust & Safety Engineer

• Please note that this role will occasionally involve handling sensitive content, including content that is sexual, violent, or otherwise disturbing. • A PEEK AT OUR TECHNICAL STACK • Our API for content moderation and policy enforcement is written in TypeScript, and runs in ECS containers on AWS Fargate. We leverage multiple AWS-native components, such as S3, CloudFront, Lambda, Kinesis, and SQS, as building blocks of our infrastructure. • Our inference backend — where safety checks run inline with generation - is written in Python (PyTorch), and is deployed across multiple clusters. We heavily leverage LLMs - both Anthropic Claude and Google Gemini - as part of our safety and moderation systems. We invest in Prometheus and Grafana for monitoring, and Terraform to manage our infrastructure. • 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 • Runway strives to recruit and retain exceptional talent from diverse backgrounds while ensuring pay equity for our team. Our salary ranges are based on competitive market rates for our size, stage and industry, and salary is just one part of the overall compensation package we provide. • There are many factors that go into salary determinations, including relevant experience, skill level and qualifications assessed during the interview process, and maintaining internal equity with peers on the team. The range shared below is a general expectation for the function as posted, but we are also open to considering candidates who may be more or less experienced than outlined in the job description. In this case, we will communicate any updates in the expected salary range. • Lastly, the provided range is the expected salary for candidates in the U.S. Outside of those regions, there may be a change in the range, which again, will be communicated to candidates. • WORKING AT RUNWAY • Great things come from great teams. https://www.youtube.com/watch?v=kwmj4ato2kw&ab_channel=Runway We’d love to hear from you. • We’re committed to creating a space where our employees can bring their full selves to work and have equal opportunity to succeed.
