As a Blockchain Engineer at Fullstack, you will build the foundational infrastructure that powers a next generation trading platform. You will design and ship core blockchain systems that prioritize reliability, speed, and precision under real world conditions. You will work deep in consensus, networking, and execution layers. You will collaborate closely with product and frontend teams to ensure the underlying protocol delivers a seamless experience for end users, even in the most demanding market conditions.
Consensus & State Machines: Implement, harden, and extend consensus protocols to guarantee safety and liveness under adversarial network conditions. Design and optimize state transition functions. Handle block proposal, voting, and finalization logic.
Execution Layer Integration: Work with Ethereum-compatible execution clients. Bridge consensus layer with execution engine. Implement payload building, block validation, and state root verification. Design execution extensions for data pipelines.
Cryptographic Primitives: Implement signature schemes for validator authentication and vote aggregation. Work with threshold signatures, BLS aggregation, or similar schemes. Ensure cryptographic security across the stack.
Performance & Scalability: Optimize block times, transaction throughput, and state storage. Profile consensus critical paths. Design for horizontal scalability and network growth.
Experience: 2+ years building blockchain systems or consensus engines in Rust (not just smart contracts). Deep understanding of memory management, concurrency, and performance optimization.
Distributed Systems: Strong grasp of leader election, state machine replication. Experience with consensus protocols like PBFT, HotStuff, Tendermint, or similar.
Storage & Performance: Comfortable working with low-level storage engines (RocksDB, MDBX) and optimizing state trie structures. Know your way around key-value stores.
Cryptography: Solid fundamentals in applied cryptography: elliptic curves, BLS signatures, threshold schemes.
Networking: Experience with P2P networking and gossip protocols. Can reason about network partitions and adversarial conditions.
Cross-Chain (Bonus): Experience with cross-chain bridges, interoperability protocols, or multi-chain architectures.
In-Person Collaborator: Thrive in high-bandwidth, in-person engineering environments.
Work Authorization: Must be authorized to work in the United States.
