Software Engineer, Console

At Keycard, we’re building identity & access infrastructure for the agent-native era—where software isn’t static, but a dynamic, constantly changing system of AI agents working on behalf of people and businesses to complete dynamic tasks at runtime.

Our mission is to unlock the agent economy by empowering developers and enterprises with the secure, scalable foundations they need to build, deploy, adopt, and trust agentic applications. To do this, we’re building the real-time, in-band, contextual guardrails required to transition from human-driven to truly autonomous and agentic workflows that give users, builders, and security teams the confidence and control they need to bring agents out of the lab and into production.

At our core, we’re laser-focused on delivering a delightful, best-in-class developer experience that gives them the tools they need to create category-defining applications and experiences while giving platform and security teams the security, scalability, visibility, control, and enablement they need to accelerate their organizations journey to becoming agent native.

We’re a small, distributed team of repeat founders and builders, with backgrounds from Snyk, Auth0, HashiCorp, and Heroku.

Joining Keycard now means helping define not just our technology, but also the culture and company we’re building together—during a once-in-a-generation platform shift.

We're hiring a software engineer to build the surfaces where agents and humans interact with Keycard: the console, the CLI, the APIs, and whatever new interaction patterns emerge as agents become first-class users of developer platforms.

Agents won't on-board to Keycard by clicking through web interfaces alone. They'll use CLIs, APIs, and machine-readable configuration. The web console is still a large part of this role — humans need to set policy, investigate events, and understand what their agents are doing — but it's not the only interface.

You'll work on the primary customer-facing team, building across the full stack. Some days that's React. Other days it's CLI commands or API ergonomics for agent onboarding. You care about how things feel to use, whether the user is a person or a program.

• Full-stack experience. Comfortable building a React/Next.js frontend, a CLI in a language like Go, and the API layer underneath.

• You use AI tools daily and have opinions about how agent-facing interfaces should work. You've thought about what it means to design for non-human users.

• Design sense. You notice when something is awkward, slow, or confusing.

• You've built CLIs, SDKs, or developer-facing tools and understand that the quality bar is different from internal tooling.

• Comfortable in an early-stage environment where you'll define the product as much as you build it.

• Experience with design systems, component libraries, or establishing frontend standards on a small team

• Background in developer tools and API design

• UX/UI design experience, even informal — Figma skills, design background, or a portfolio of things you've built that look and feel good

• Experience building interfaces that serve both human and programmatic consumers

• 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.

Keycard is building the fundamental unlock for the next generation of software: enabling truly secure and trusted agentic applications. Under the hood, we’re building a new identity and access control stack to take us from a world of static, user-focused, long-lived roles and credentialing to one of mixed machine & human interaction that is dynamic, contextually-scoped, and short-lived.

By joining as an early employee, you’ll have the opportunity to help curate a culture of iterative craftsmanship, disciplined design, empowerment to own meaningful problems, and consistent high-quality delivery with real impact. You’ll collaborate with the founders and investors who have championed identity, security, and developer tools from seed to scale with companies like Snyk, Auth0, and Heroku.

If you’re energized by tackling complex distributed systems and want to advance both developer productivity and security posture, with a hunger to learn, have an impact, and move quickly with determination we’d love to explore how you can help us shape the future of software.
