About Keycard

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, and we’re backed by world-class investors including Boldstart, a16z, and Acrew Capital. 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.

What You'll Do

Unlock the Future of Agentic Workflows: Craft the experiences and visualizations that make it easy for anyone to understand and build trusted agent experiences with best-in-class Generative UI and Asynchronous Workflows using drop-in SDKs.
Distill Complex Concepts into Simple Experiences: Work with the entire team to create a beautiful, simple, and easy to onboard experience that gets developers deploying to production in minutes instead of hours that balances rapid-fire flows for engineers with data-rich, investigation-grade views for security.
Design & Build Rich, Graph-Based Experiences: Build a Figma-like canvas that makes it easy for engineers and security alike to understand and modify the behaviour of agents and the resources they're attempting to access with zero code changes in real time.
Own the End-to-End Stack: Establish the design system, build pipeline, testing strategy, and performance budgets for all web assets, and embeddable widgets.
Mentor, Learn & Grow: Share knowledge through pairing, design reviews, and internal talks while learning from experts in systems, security, and AI.
Shape Engineering Culture: Influence how we work and the standards we set for developer experience, accessibility, and technical excellence.
Architect & Implement our Frontend Platform: Use React/Next.js + TypeScript, leaning on modern paradigms like Server Components and edge rendering that enables us to quickly deliver stunning, and simple user experiences with confidence.
Build State of the Art, Data-Intensive Experiences: Create powerful data-intensive experiences, from rich-graph visualizations to slick onboarding experiences that make it simple to get up and running in seconds through graph-based drag & drop experiences (SVC/WebGL/Canvas) and data-rich visualizations that embed AI natively throughout using the latest LLM & RAG techniques.
Establish the Tone for Frontend Engineering at Keycard: Establish the norms and expectations for what a best-in-class web experience looks like at Keycard, ensuring we deliver beautiful, performative, and reliable frontend experiences using Web Vitals budgets, Playwright/Cypress suites, and a fully instrumented experience for data-driven iteration.
Establish a Scalable, Design Esthetic: Partner with design to codify a design system with a component library that bakes in accessibility for Keycard and Generative UI experiences.

What We're Looking For

5+ years building production SPAs/SaaS products with React/Next.js, TypeScript, Vite/SWC.
Graph & Data‑viz Chops: Comfort with D3, Visx, or similar for large‑scale graph rendering, and a track record of performance‑tuning Canvas/WebGL apps.
Design‑System Mindset: Experience creating or evolving component libraries at scale, documented in Storybook or similar.
Figma‑Like Interaction Expertise: Built or contributed to node‑based editors, diagramming tools, or collaborative canvases (CRDTs/op‑based syncing a plus).
Security & Developer‑Tool Empathy: Familiarity with IAM, policy engines, or AppSec workflows; passion for clean abstractions that serve both builders and defenders.
Ownership & Autonomy: Thrive in 0→1 environments, balancing long‑term vision with rapid delivery.

Strong Candidates May Also Have

Experience visualizing identity graphs, authorization policies, or threat‑model diagrams.
Familiarity with LLM app frameworks (LangChain.js, Next.js AI) and embedding conversational agents into UIs.
Exposure to edge‑rendering and server components on platforms like Vercel or Cloudflare Workers/Pages.
Contributions to open‑source front‑end tooling, data‑viz libraries, or AI/identity projects.
Passion for automation—scripts, bots, or agents that remove toil from your workflow.

What We Offer

Mission-Orientated Culture: Join a team laser-focused on delivering the future of identity and access controls for agents – a once in a generation opportunity to build the foundational infrastructure and help define the protocols and primitives necessary to unlock the real potential of agents and help build an industry-defining company from the ground up.
Be Heads-Down & Focused: Feel the impact of your work everyday, building, inventing, and iterating on all aspects of our product. Spend your time being heads-down shipping at the forefront of agentic systems and wake up every day understanding the significance of your contributions with a team who wants to win.

Why Join Us?

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.
