Software Engineer, Full Stack

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
