Senior Frontend Engineer (AI-Native)

Our client is a well-funded Web3 / identity startup building a human verification layer for the AI era. The product helps apps and platforms verify real humans without collecting invasive personal data. Think Sybil resistance, privacy-first identity, and developer-friendly infra.

They already have millions of users and a live product. Now they want to level up the frontend and move faster with AI-native engineering workflows.

---

What You’ll Do

• Own the main user dashboard and identity flows (React, Next.js, TypeScript)

• Ship production UI fast using AI coding tools as core workflow

• Build clean, responsive, accessible interfaces for onboarding and verification

• Write and maintain E2E and integration tests for critical flows

• Integrate with backend APIs and auth systems

• Own what you ship in production. Monitor, fix, improve

• Help shape frontend architecture and standards

---

What We’re Looking For

• 4+ years frontend experience with React + TypeScript

• Strong Next.js experience (SSR, modern React patterns)

• Daily use of AI coding tools (Cursor, Claude Code, Copilot, agent workflows)

• Solid testing mindset (E2E, integration)

• Comfortable with monorepos and modern tooling

• Confident with CLI, Docker, basic infra workflows

• Clear async communication

Nice to have

• Web3, identity, ZK, or security-sensitive frontend experience

---

You’ll Do Well Here If

• You treat AI as default infrastructure, not a side tool

• You ship fast and own the result

• You communicate early when blocked

• You can move in messy codebases without drama

• You care about product quality, not just code elegance

---

Stack

• Frontend: React, Next.js, TypeScript, Tailwind

• Backend: Node.js, TypeScript

• Infra: AWS, Docker, CI/CD

• Data: Postgres, Mongo

• Web3: EVM chains

Why This Role Is Different

This is not a traditional frontend role.
The team is fully AI-native. You are expected to:

• Use agentic coding workflows daily

• Let AI scaffold, test, refactor, and debug

• Apply human judgment on auth, security, and data-critical flows

• Know where AI fails and how to catch it

Strong signal if you already work with:

• Claude Code, Cursor, Codex CLI, OpenCode

• Test-first workflows with AI

• Prompt and context management for agents
