About Subzero Labs
Subzero Labs is building the next generation of decentralized infrastructure.
Position Overview
We seek exceptional Software Engineer: Distributed Systems to design and build critical infrastructure components for our decentralized network.
What You'll Do
Block Propagation & Networking: Design peer-to-peer protocols for efficient block gossip, implementing error-coding, compression, and retransmission strategies to minimize bandwidth and latency.
Dynamic Workload Management: Architect schedulers handling unpredictable conditional transactions while preserving system throughput.
State-of-the-Art Consensus: Design and implement state of the art consensus protocols optimized for low latency, fairness, and throughput under adversarial conditions.
Parallel Execution: Implement concurrency control using lock-free data structures and speculative execution to run hundreds of transactions in parallel without state conflicts.
State Management & Storage: Architect high-performance Merkleized key-value stores with efficient pruning, compaction, and snapshotting mechanisms for fast bootstraps and state syncs.
Censorship Resistance: Build mechanisms ensuring transaction submissions cannot be blocked by single nodes or external observers.
Performance Engineering: Implement real-time metrics and Grafana dashboards tracking end-to-end latency, throughput, and resource consumption. Profile systems to identify performance bottlenecks and mitigate them.
Required Qualifications
