Fal AI Machine Learning Engineer, Safety at Fal AI responsible for owning ML models and infrastructure powering safety and abuse-detection systems. Improve detection pipelines and integrate safety systems into core platform infrastructure.
Responsibilities
fal is looking for a Machine Learning Engineer to own the ML and the ML infrastructure that power our safety systems end-to-end — from the models that detect harmful content and misuse to the pipelines and infrastructure that run them reliably at scale. This is a dedicated, hands-on engineering role sitting on the Trust & Safety team, working alongside our safety engineering function to keep detection capability ahead of a fast-growing platform with 1,000+ models.
Design, build, and maintain the ML models and the ML infrastructure behind fal's safety and abuse-detection systems, end-to-end
Improve the accuracy, coverage, latency, and scalability of detection pipelines across the platform
Partner with Security and Infrastructure Engineering to integrate safety systems deeply into core platform infrastructure
Evaluate and integrate third-party safety tooling and vendor models where it makes sense
Stay current with the ML safety/detection landscape and bring new techniques and infrastructure patterns into fal's stack
Some core technologies we use include Python, torch, diffusers, Kubernetes, and the fal Python SDK
You'll work alongside a team dedicated to quickly iterating on and deploying new AI breakthroughs — your job is to make sure that speed never comes at the cost of safety
