Keycard Labs is a company that specializes in creating a unified identity infrastructure for agents, tools, and applications. They provide solutions that enhance agent security and control through dynamic, task-scoped access tokens, allowing developers to build trusted AI experiences while ensuring compliance and visibility. With a focus on eliminating secret sprawl, Keycard Labs enables organizations to delegate access securely and efficiently, supporting the development of autonomous agents in a compliant manner.

📋 Description

• 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.

🎯 Requirements

• You're a builder first, operator second — a programmer at heart who uses Go and/or Rust to create platforms and product systems. You've built developer-facing platforms (Kubernetes operators, CI/CD abstractions, internal tooling) as well as core services, and you think in terms of dynamic, reactive systems. • Strong distributed systems instincts. You have expertise in consensus, coordination, and state management, and you build systems that are secure, resilient, and fault-tolerant with best-in-class observability. • You treat the path to production as a product surface. You create automation, pipelines, and developer platforms that make shipping reliable software the default — empowering every engineer to deliver quickly and with confidence. • You thrive in 0→1 environments. You make hard trade-offs to ship today while laying groundwork for the long-term system, and you use iteration to accelerate the learning loop. • You lead by example — raising the bar for technical excellence while helping those around you grow. You communicate clearly through written plans and async updates, and know when to jump on a call. • Strong Candidates May Also Have: Experience with identity and access protocols (OIDC, OAuth, mTLS) and active engagement with emerging agent protocols like MCP and A2A. • Experience extending runtimes with eBPF, service meshes, custom Kubernetes operators, or plugin-driven architectures (WASM, dynamic policy engines).

🏖️ Benefits

• Build at the Frontier: Work every day at the frontier of agent-native systems — shipping, inventing, and iterating on technology that hasn’t been built before. You’ll be given huge autonomy, the opportunity to gain mastery, and the chance to work in a team that holds each other accountable to succeed. • Truly Agent-Native Culture: At Keycard, we don’t just enable others to adopt agents — we use them ourselves to build. You’ll help shape an organization that embeds AI into its foundation as an enduring competitive advantage. • Compensation With Upside: Market-competitive salaries and generous equity packages (4-year vest, 1-year cliff) give you the security to focus on building — and the asymmetric upside of ownership in a company chasing a category-defining mission. • Comprehensive Benefits & Recharge: Health, dental, vision, and paramedical coverage for you and your family, plus 4 weeks vacation, 11 statutory holidays, and 1 volunteer day annually. We encourage at least 2 weeks off each year to fully recharge. • Tools That Keep You Ahead: A new MacBook Pro, a $500 stipend for peripherals, and the best AI tools available so you can work at the forefront of agent-native workflows. • Remote-First Flexibility: We are a remote-first team prioritizing asynchronous collaboration, with hiring focused in North and South America. Work where you’re strongest — we just want the best.
