About the Company:
World is building a real human network designed to accelerate people in the age of AI. As bots and autonomous agents reshape the internet, people, institutions, and applications need a trusted way to confirm who is a real human while preserving privacy. Our products make this possible: the Orb verifies real people, World ID proves it privately, and World App enables and distributes the new applications made possible by this technology. Together, they form a new layer for AI internet.
We’re one of the fastest-growing networks in tech. More than 17 million people across 160 countries have verified with World ID, and we complete over 350,000 verifications each week. World App is already among the most used wallets globally. Developers are integrating World ID to build safer online experiences and create spaces where real people can participate, earn, and be recognized in ways AI simply can’t replicate.
World was founded in 2019 and launched globally in 2023. We are more than 400 people across hardware, software, AI, cryptography, mobile engineering, and global operations. Our teams come from OpenAI, Tesla, SpaceX, Apple, Google, Stripe, Meta, Coinbase, Palantir and MIT Media Lab. We’re backed by leading investors, including a16z, Khosla Ventures, Bain Capital Crypto, Blockchain Capital, Variant, Tiger Global, and Coinbase Ventures, as well as prominent operators and founders across fintech and AI.
World has been featured on the cover of TIME Magazine, highlighted in Fast Company’s Next 5 in Fintech, and explored in a Bloomberg deep dive. The New York Times, Bankless and TechCrunch have all recognized our progress in identity, cryptography, AI, and global-scale hardware deployment. Our leadership is also named to the Time AI 100.

About the Team
You’ll join a fast-moving product engineering team responsible for end-to-end experiences across web and APIs — from design to deployment.
We build and operate:
- Next.js apps with React/TypeScript
- Node.js services and serverless functions
- A GraphQL-powered data layer and event-driven pipelines
- Secure auth flows and developer tooling for fast iteration
We value strong product sense, pragmatism, and craftsmanship. You’ll work closely with design, data, security, and infra to ship measurable impact quickly.
What You’ll Do
- Build polished, accessible user experiences in Next.js/React/TypeScript
- Design and implement performant Node.js APIs and serverless endpoints
- Integrate with GraphQL (Hasura) and internal services with robust typing and codegen
- Ship secure auth and session flows (Auth0, middleware, edge/runtime where appropriate)
- Own features end-to-end: specs, implementation, observability, rollout, and iteration
- Improve performance (SSR/SSG, caching, streaming, bundle budgets) and reliability
- Collaborate on API contracts, data models, and experiment frameworks with product/data
- Contribute to developer experience: shared libraries, lint rules, codegen, docs
What We’re Looking For
- Substantial experience shipping production web apps:
- Next.js, React, TypeScript, Tailwind CSS
- Node.js/TypeScript services (REST/GraphQL), serverless and edge patterns
- Strong product intuition — balancing speed, UX quality, and correctness
- Familiarity with data modeling and GraphQL (preferably Hasura) and SQL fundamentals
- Clear communication, ownership mindset, and ability to execute in ambiguity
- IC3: independently delivers scoped features end-to-end; contributes to team standards
- IC4: leads multi-sprint projects; improves architecture; mentors others; raises the quality bar
Nice to Have
- AWS (Lambda, API Gateway, S3, CloudFront, CloudWatch) and IaC (CDK/Terraform)
- Observability (metrics, tracing, logging) and performance profiling
- CI/CD, feature flags, canary/gradual rollouts, OpenNext/serverless Next.js experience
- Write high-quality tests (unit, integration, e2e with Vitest/Playwright) and maintain CI quality bars
How We Work
- Pragmatic, testable designs; small, fast iterations
- Type-safe APIs and shared contracts
- Strong code reviews, clear RFCs, and data-informed decisions
- Blameless postmortems and continuous improvement
Minimum Qualifications
- Professional experience with Next.js, React, TypeScript, and Node.js
- Track record of shipping user-facing features and backend integrations
- Proficiency with Git, and modern build tooling
