Role

Who you are

7+ years as a Full‑Stack Engineer or equivalent experience, with a focus on:
Front‑end: Production-grade React & Next.js, Typescript, modern web tooling
Backend: Python (FastAPI/Django/Flask), microservices, REST/GraphQL, distributed systems
Proven track record at scale - building high‑traffic, low‑latency systems (e.g., handling tens of millions of users/wallets)
Solid familiarity with blockchain fundamentals (EVM chains), crypto wallets, wallet abstraction, dapp architecture
Experience integrating with blockchains: RPC, on‑chain transactions (i.e., viem), gas/nonce management, wallet flows
Strong understanding of security best practices and compliance; experience in security-minded architectures
Excellent communication, mentorship, and autonomous execution at a senior engineering level
Proficiency with AI coding tools (Copilot, Cursor, Codex, Warp, etc.)

Desirable

Direct experience building or contributing to blockchain/dapp infrastructure or tooling
Nice to have: Knowledge of secure enclaves and zero knowledge proofs—handling secure approvals, cryptographic proofs (TEEs, ZKPs)
Proficiency with Rust
Built authentication flows (OAuth, session management, 3rd‑party identity providers, embedded wallet flows)
Familiarity with cloud infrastructure at scale—Kubernetes/ECS, serverless, CI/CD (GitHub Actions), distributed logging/metrics

What the job involves

We’re seeking a Senior Full‑Stack Engineer to join the Magic Labs team
You’ll play an integral role in building and supporting systems, including our TKMS secure enclave key management system (TypeScript, node.js), API Wallet Express, our easy to implement API based key management system (Python), and new products that leverage Netwon, our blockchain-based policy engine (Python, TypeScript, React, Next.js)
This role will solve challenging implementation problems at crypto-scale, onboarding additional chain support, adding new use cases, and building both frontend and backend features
Architect and implement full‑stack features: responsive UIs with React/Next.js and robust Python APIs with FastAPI services
Build, optimize, and scale backend services supporting millions of users
Work closely with product and security teams to ensure our systems meet Security and SOC 2/ISO/HIPAA-grade standards
Design and integrate features that leverage the Newton policy protocol and help bring experiences that leverage the protocol to the masses
Collaborate with protocol team to enable verifiable on‑chain agent actions (powered by TEE + ZK proofs)
Lead and mentor other engineers, drive code reviews, set best practices for maintainable, scalable architecture
Ensure and enhance authentication flows (Email OTP, passkey, Web3 logins, session safety) in our full‑stack apps

Our take

Password-based authentication is notoriously fragile - with many people reusuing the same password for every site they use, and the majority of all breaches caused by passwords. Magic is striving to bring an end to the traditional password authentication method, by providing developers with the tools to adopt secure, passwordless instant access to Web 3.0 wallets.

The company is trusted by Web 3.0 trailblazers including ImmutableX, Magic Eden, Zerion and Helium. It has continued to develop new capabilities as the Web 3.0 space matures - for instance with its collaborative launch of an all-in-one Web 3.0 loyalty solution with Uptop - to ensure that it remains able to deliver what the industry needs.

Magic has attracted significant investment from the likes of Northzone and Tiger Global, as well as from PayPal Ventures. This capital is being used to support the expansion of its functionality and the building up of more use cases.
