United States onlyAbout Magic Labs
Magic is innovating at the intersection of crypto and AI to make wallets invisible and capable of running on autopilot.
In 2018, we introduced the first embedded wallet, enabling users to create wallets with just an email or social login. This approach has since become standard across much of the industry. To date, we’ve helped onboard over 50 million wallets and 200,000 developers, supporting projects like Polymarket, Helium, WalletConnect, and Immutable, as well as enterprises such as Forbes, Mattel, and Naver. We’re backed by investors including PayPal Ventures, Lightspeed, Placeholder, SV Angel, Naval Ravikant, and Balaji Srinivasan.
Today, we’re building Newton to help bring about the wallet endgame—where AI and automation completely abstract away the complexity of onchain interactions beyond wallet creation. This means applying state-of-the-art technologies from both AI and crypto and delivering them through a product and protocol that can scale to billions. Our vision is a future of self-driving capital that extends the financial system upgrade made possible by web3.
This role is open to candidates based anywhere in the US or Canada, with a slight preference for those in commuting distance of NYC.
Unfortunately, we are unable to sponsor or take over sponsorship (ex., H-1B transfer) of employment visas, and applicants must be authorized to work for any employer in the US or Canada.

- 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 and signing curves
- Experience integrating with blockchains: RPC, on‑chain transactions (i.e., viem), gas/nonce management, wallet flows.
- Familiarity with cloud infrastructure at scale: Kubernetes/ECS, serverless, CI/CD (GitHub Actions), distributed logging/metrics.
- 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.)
Preferred Skills
- Direct experience building or contributing to blockchain/dapp infrastructure or tooling.
- Nice to have: Knowledge of zero knowledge proofs - cryptographic proofs (ZKPs)
- Built authentication flows (OAuth, session management, 3rd‑party identity providers, embedded wallet flows).
