Overview
We’re hiring a Lead Blockchain Architect to design and deliver a next-generation Layer 1 blockchain. You’ll be responsible for architecting and implementing high-performance distributed systems, capable of handling millions of transactions with sub-second finality.
This is a hands-on architect role: you must be able to design from first principles, build core consensus and execution logic in Rust, and either develop a new L1 or fork and evolve an existing high-performance chain such as Sui.
Candidate Profile
Experience: 8–12+ years in systems programming, blockchain infrastructure, or distributed systems engineering.
Deep Expertise: Rust, consensus algorithms, parallel execution engines, validator networks, cryptography.
Blockchain DNA: Contributed to or forked major L1/L2 projects (Sui, Solana, Cosmos, Ethereum, Aptos, Hyperliquid).
Visionary Builder: Proven ability to design systems that scale to millions of daily transactions.
Claude-First: Comfortable using Claude AI for system design, code generation, audits, and debugging.
Cultural Fit: Outcome-driven, thrives in high-pressure, high-reward startup environments.
Technical Stack / Core Skills
Rust: Expert-level, for consensus and execution engine development.
Move: Familiarity with Move-based smart contract platforms (Sui, Aptos).
Solidity/EVM: Knowledge of EVM standards for interoperability.
Consensus: Experience with Proof-of-Stake, parallel execution, and randomness.
Infrastructure: Validator/node software, networking, sharding, storage layers.
Security: Strong understanding of consensus exploits, cryptographic security, and audit practices.
Tooling: SDKs, APIs, developer environments, block explorers.
Responsibilities
Architect and deliver a new Layer 1 blockchain or evolve an existing fork (e.g. Sui).
Lead the design of consensus, execution, and validator models with sub-second finality.
Define and implement protocol-level tokenomics and staking mechanics.
Design and build secure cross-chain bridges to Ethereum, Solana, and other ecosystems.
Establish coding standards and technical roadmap for the blockchain team.
Use and evangelize Claude-assisted workflows to accelerate architecture and development.
Recruit, mentor, and lead a team of world-class Rust/blockchain engineers.
What We Offer
- Autonomy: ability to move fast and ship without red tape.
- A chance to build one of the world’s fastest and most scalable blockchains from the ground up.
- Authority and ownership: you will define and own the technical direction of the chain.
- Competitive compensation with major equity/token upside.
