Keycard Labs

Full-stack Engineer

• We're hiring a Staff Platform Engineer to build the core systems and infrastructure that power Keycard — from identity services and enforcement paths to the developer platforms and automation that let every engineer ship with confidence.
• You'll work directly with founders, product, design, and the engineers building our SDKs and core services. You'll also help shape how we use agents internally — contributing to how Keycard becomes an agent-native engineering organization, not just a company that builds for one.

Software Engineer – Systems

• We're hiring a Staff Identity Engineer to design and build the core identity, authentication, authorization, and data systems at the heart of Keycard.
• The systems you build need to be dynamic, multi-tenant, and fast — delivering auth decisions in under 10ms across cloud, edge, and hybrid deployments.
• Your work will span from core distributed services to the SDKs and APIs that developers use, ensuring a seamless, trusted experience end to end.
• You'll work directly with founders, product, design, and the engineers building our SDKs and platform services. You'll also help shape how we use agents internally — contributing to how Keycard becomes an agent-native engineering organization.

Software Engineer, Identity

• We're hiring a Staff Data Engineer to design and build the operational data systems that power Keycard — the pipelines, storage layers, and APIs that drive near real-time enforcement, feedback loops, and customer insights.
• The systems you build will serve both the transactional needs of our core identity services and the OLAP requirements that help organizations understand and improve their security posture. You'll balance streaming and batch paradigms — knowing when low-latency streaming is essential and when batch provides clarity and power.
• Your work will span from integrating external data sources to enabling policy evaluation to surfacing insights in dashboards and APIs.
• You'll work directly with founders, product, and the engineers building our core services and SDKs. You'll have deep autonomy, accountability to deliver, and the chance to shape the data architecture of a category-defining company from the ground up.
