A Keycard Labs é uma empresa especializada em criar uma infraestrutura unificada de identidade para agentes, ferramentas e aplicações.

Com foco na eliminação da disseminação de segredos, a Keycard Labs capacita as organizações a delegar acesso de forma segura e eficiente, apoiando o desenvolvimento de agentes autônomos de maneira conforme.

Descrição

• We're hiring an engineer to join the team that builds and owns the Keycard Agent SDK — the libraries that bring trust, governance, and telemetry to AI agents in production. • Keycard is a control plane for agents: policy enforcement, identity propagation, audit logging, and runtime governance. The SDK is how developers use it. • You'll build the SDK libraries, maintain compatibility with upstream frameworks, contribute to open protocol work (MCP, A2A), and advocate for what agent developers actually need. • You'll work directly with founders, product, and the systems engineers building the underlying services.

🎯 Requisitos

• You follow the agent ecosystem closely — you build with these tools and have opinions about what works, what doesn't, and when to use which framework. • Strong systems engineering instincts. You write tests, think about backwards compatibility, version correctly, and care about API surface area. • You've built libraries or SDKs that other developers depend on. You understand the difference between building a product and building a tool others build products with. • You work across multiple languages without treating any of them as second-class. • Strong candidates may also have • Experience with plugin systems, provider architectures, or marketplace/ecosystem engineering (Terraform providers, VS Code extensions, Stripe integrations, etc.) • Contributions to open source agent frameworks or protocols • Background in identity/auth protocols (OIDC, OAuth, mTLS) at the library level • Experience with code generation tools (OpenAPI, protobuf, smithy) for multi-language SDK maintenance

🏖️ Benefícios

• 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.
