About the role

Key responsibilities & impact

Full Stack Feature Development: Architect and deliver end-to-end features across a modern TypeScript monorepo (Bun, Turborepo) with an emphasis on type-safe boundaries, domain-driven design, and system correctness for financial workloads.
Edge Infrastructure & Serverless Services: Build and manage stateful, event-driven systems utilizing the Cloudflare platform (Workers, Workflows, Durable Objects, Queues, R2, D1, KV, Pipelines, and scheduled triggers) using Wrangler and Alchemy.
Web3 Integration & Execution: Implement Web3 workflows using Viem/Wagmi, ZeroDev Kernel smart accounts, session-key permissions, SIWE/Privy authentication, and bundler/paymaster infrastructure across EVM environments.
Backend & Workflow Orchestration: Design idempotent, replay-safe execution paths across distributed services using Hono, tRPC, Zod, and real-time event systems.
Frontend Engineering: Develop responsive, accessible, and high-performance interfaces using React, Vite, TanStack Router/Query/DB, and Tailwind CSS with polished motion and real-time state updates.
AI & Agent Infrastructure: Integrate practical AI workflows utilizing the Cloudflare Agents SDK, Workers AI, AI Gateway, Vectorize, structured outputs, tool calling, and evaluation-driven pipelines.
Modern Engineering Workflows: Leverage AI-assisted coding tools (e.g., Codex, Claude Code) for rapid research, testing, and implementation while maintaining strict ownership of architecture, security, and code quality.
Quality Assurance & Observability: Maintain high test coverage using Vitest, Playwright, and workerd-based integration tests while monitoring system health via structured logs, correlation IDs, Sentry, and Cloudflare observability.

Requirements

What you’ll need

Core Technical Fundamentals: Strong mastery of TypeScript and software engineering principles, with experience building robust, maintainable systems.
Deep Onchain & DeFi Knowledge: Solid technical and economic understanding of core Web3 primitives, including automated market makers (AMMs), decentralized exchanges/swaps, lending protocols, and perpetual futures.
Stack Versatility: Meaningful technical depth in at least one key area of the stack (Cloudflare edge infrastructure, EVM/smart contracts, complex React frontends, or distributed backends) with a demonstrated ability to learn new technologies quickly.
EVM Proficiency: Solid experience with EVM execution environments. Familiarity with Solana (SVM) or cross-chain messaging/execution frameworks is a strong plus.
Distributed Systems & Debugging: Practical experience with distributed tracing, structured telemetry, and edge-native debugging.
Mindset: Adaptable, autonomous, and motivated by building meaningful financial tools at the technical frontier.
