Job Description

Senior Infrastructure Engineer - High-Performance Blockchain Services

Location : New York, San Francisco (Office)

Compensation : $200K - $400K

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).
