About Keycard

Keycard is on a mission to redefine machine identity for the AI Era—empowering developers to seamlessly connect people, agents, and services across networks, clouds, and applications. As generative AI and agent-based workflows grow more sophisticated, they demand real-time, adaptable access patterns. Keycard unlocks dynamic, identity-based credentials, ensuring every agent and service operates with precise, contextual permissions—creating a robust foundation for trusted AI systems.

We envision a global identity network, underpinned by open protocols, allowing distributed systems to adapt dynamically, scaling to handle complex AI workloads, and maintain cryptographically verifiable trust relationships. By rethinking secret management and machine identity from first principles, our goal is to delight developers, meet the performance demands of platform engineers, and establish new security primitives for cloud-native architectures—all in an inclusive, collaborative environment focused on consistent, high-quality execution and crafting products that developers love so much they bring them everywhere they go.

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

→ Competitive Compensation & Equity: Market-competitive salaries with generous equity packages for early employees, vesting over 4 years with a 1-year cliff.

→ Comprehensive Benefits: Competitive health, dental, vision, and paramedical coverage for you and your family, so you can focus on building and staying healthy.

→ Flexible, Remote-First Work: As a remote-first company, we prioritize asynchronous collaboration, with hiring focused in North and South America. We want to hire the best.

→ Time Off to Recharge: We offer 4 weeks of vacation, 11 statutory holidays, 1 volunteer day, and parental leave. We encourage at least 2 weeks off annually to recharge so you can show up and push forward every day.

→ Autonomy & Impact: Join our team and shape not only our technology but also what we build and how we build it. You'll be empowered to make meaningful decisions, grow in your craft, and lead at the forefront of the AI infrastructure that is transforming the future of work.

→ Top-of-the-Line Equipment: A new MacBook Pro plus a $500 stipend for peripherals (headphones, mic, camera) so you can collaborate at your best.

→ Access to the latest AI tools: The way developers build software is evolving. To lead this transition and stay at the forefront of agent-driven workflows, you need the most powerful developer capabilities available.

Why Join Us?

Core Mission

Keycard is driving a fundamental shift in AI infrastructure: enabling trusted, autonomous agents through dynamic, identity-driven access controls. This is a rare opportunity to help define how AI systems interact and operate in production environments.

Technical Impact

You'll help invent and shape the critical infrastructure that enables widespread adoption of AI in production use cases, reinventing how developers build and deploy autonomous systems while ensuring they remain secure and trustworthy.

Culture & Team

By joining as an early employee, you'll have the opportunity to help curate a culture of iterative craftsmanship, disciplined AI development, and consistent high-quality delivery with real impact. You'll collaborate with founders and investors who have championed identity, security, and developer tools from seed to scale with companies like Snyk, Okta, Auth0, Signal Sciences, Heroku, Kraken, and Salesforce.

If you're energized by the intersection of AI systems and distributed infrastructure and want to advance both developer productivity and AI security, with a hunger to learn & have an impact, we'd love to explore how you can help us shape the future of software.
