Security Engineer

xdof | Full-Time | San Mateo

At xdof, we’re at an inflection point. Frontier labs are racing to build general-purpose robots, and high-quality training data is the bottleneck. We’re building the foundation behind the foundation models – the data collection systems, operational capability, exabyte-scale data warehouse, and software toolchain – to help our partners drive the field forward

.As more enterprise partners depend on our platform, security is infrastructure. We’re looking for a Security Engineer to own the security posture of our AWS environment and the external-facing platform our B2B customers integrate with every day. We’re early-stage, so you’ll have broad scope for security ownership across the stack
