Senior Infrastructure Engineer - High-Performance Blockchain Services

Location: New York City (Office)

Compensation: $200K - $300K

Join the Infrastructure & Platform team at a high-growth crypto derivatives exchange that is rapidly capturing market share in a multi-billion dollar annual sector. Our current focus is on building a multi-asset margin feature that leverages blockchain technology to allow users to post variable forms of collateral which is essential as multi-asset margin comprises over 86% of crypto accounts.

You will play a pivotal role in designing architecting and deploying highly reliable scalable blockchain services with lightning-fast performance. You will lead the development of mission-critical core infrastructure that powers our products enabling us to bring financial venues directly to the user.

The Senior Infrastructure Engineer will be responsible for building the core components of a high-throughput low-latency distributed system focusing heavily on performance and cryptographic integrity.

• Core Systems Development: Develop foundational components including storage layers execution engines transaction pools gossip protocols and state-machine replication mechanisms to deliver high-throughput low-latency performance.
• Consensus Engineering: Implement harden and extend consensus algorithms (e.g. PBFT HotStuff Tendermint) to guarantee safety liveness and high performance under real-world network conditions.
• Performance Optimization: Deeply profile CPU memory I/O and network stacks identify system bottlenecks and push performance limits across the platform.
• Cryptography Integration: Integrate diverse cryptographic primitives including hash functions Merkle proofs digital signatures encryption schemes key-exchange protocols and zero-knowledge proof systems.
• Networking & Transport: Design and implement reliable networking components for peer discovery NAT traversal connection pooling load balancing congestion control encrypted networking (TLS) and multiplexed transports (e.g. TCP UDP QUIC).

• Experience: 2 years of professional experience building blockchain-based distributed systems and consensus engines.
• Low-Level Languages: Expert proficiency in C Rust Zig or other low-level languages.
• Consensus Deep Dive: Deep understanding of consensus protocols (e.g. PBFT HotStuff Tendermint) and distributed systems theory.
• Cryptography Fundamentals: Strong knowledge of cryptography fundamentals including hashing Merkle trees multisignatures and elliptic-curve cryptography.
• Networking: Solid networking experience covering TCP/UDP QUIC peer discovery and NAT traversal.
• Database Experience: Hands-on experience with key-value store databases (e.g. RocksDB MDBX) for efficient state storage and high-throughput access.
• Legal: Authorized to work in the United States.
