Senior Product Engineer - Blockchain Developer Tools

Location: Remote (Global) | Blockchain Hubs Preferred

About Us

We’re redefining blockchain infrastructure by building a high-performance Layer 1 protocol that pushes distributed systems to their physical limits. Our team of low-level engineers and cryptographers is creating the foundation for next-generation decentralized applications, optimized to run on commodity hardware at unprecedented scale.

The Role

As a Senior Product Engineer, you’ll architect the developer tools and SDKs that empower thousands of engineers to build on our blockchain. You’ll bridge cutting-edge protocol development with end-user experiences, ensuring seamless integration for web, mobile, and decentralized applications.

What You’ll Build

1. Developer SDKs: TypeScript/React libraries for web and mobile that abstract blockchain complexity
2. Secure Wallets: Reference implementations with best-in-class authentication and key management
3. CLI Tooling: Code-gen pipelines, contract deployment utilities, and testing frameworks
4. RPC Infrastructure: High-performance endpoints for querying chain data and submitting transactions

Key Responsibilities

1. Design ergonomic APIs that expose advanced cryptography and consensus features to developers
2. Optimize developer experience (DX) through intuitive documentation, samples, and error handling
3. Collaborate with protocol engineers to align SDK capabilities with network upgrades
4. Lead open-source initiatives, gathering feedback from hackathons and ecosystem partners
5. Implement CI/CD pipelines and automated testing to ensure SDK reliability at scale

Tech Stack & Requirements

1. Core Languages: TypeScript, React, React Native, Swift/Kotlin (mobile)
2. Blockchain: JSON-RPC, smart contract integration, wallet standards (EIP-1193, BIP-39)
3. Tools: Node.js, Vite, Webpack, Jest, Playwright
4. Experience:
5. 4+ years shipping developer-facing tools (SDKs, CLIs, libraries)
6. Proven track record optimizing developer onboarding and adoption
7. Familiarity with blockchain concepts (wallets, transactions, gas mechanics)

Mindset:

1. Obsessed with DX metrics (time-to-first-query, error rates, etc.)
2. Thrives in ambiguous, fast-paced environments
3. Communicates complex concepts with clarity (written and verbal)

Nice-to-Have Skills

1. Rust, Go, or C/C++ for contributing to protocol-layer integrations
2. Experience with MPC, hardware wallets, or zero-knowledge proofs
3. Background in distributed systems or performance optimization
4. Open-source contributions to developer tools or blockchain projects
