About the company
fal is the generative media ecosystem powering the next generation of AI products. We build the infrastructure, tools, and model access that teams need to move from idea to production, and do it at scale without compromise. For developers and enterprises, fal is the foundation that makes generative media not just possible, but practical: a unified platform where high-performance inference, orchestration, and observability come together to unlock new categories of AI-native products.
As generative media reshapes industries across a market projected to grow by hundreds of billions over the next decade, fal is becoming the ecosystem that ambitious teams build on.
About the Role
We’re hiring for a Staff Detection & Response Engineer to build fal’s detection and response (D&R) program. You’ll own how we find, investigate, and contain threats across our organization and ecosystem. You’ll set the strategy, select the tooling, build the system, and lead incidents end to end, with room to grow the team as the program matures. Proficiency in building with and using AI is central to this role.
What You’ll Do
Build Detection
•
Stand up logging and telemetry pipelines across cloud, Kubernetes, bare-metal GPU hosts, threat intel platforms and identity/SaaS providers
•
Write, test, and tune detections as code, keeping signal high and noise low
•
Lead and run threat hunting to turn findings into lasting detections
•
Build AI-driven detection and response, using LLMs and agents for triage, enrichment, investigation, and alert correlation
Own Incident Response
•
Lead incidents from triage and containment through forensics, communication, and post-incident review
•
Write the IR plan and playbooks, establish severity models, and set on-call rotations
•
Design and lead tabletop exercises with engineering and leadership
Shape the Program
•
Own the D&R roadmap and build-vs-buy decisions
•
Define and report on coverage, MTTD, and MTTR
•
Partner with infra, platform, and ML teams to fix the gaps exposed by incidents
•
Own detection and incident response controls and evidence for SOC 2, ISO 27001
