Core Engineer

Bulk Exchange is building the first block-less, leader-less, geographically distributed exchange (CLOB), targeting <25 ms matching latency globally. By embedding our “Bulk Tile” matching layer within a custom fork of the Solana validator (Bulk-Agave), we deliver HFT-grade performance with L1 security and on-chain finality.

Our team culture

• High ownership: Every team member drives architecture and roadmap decisions.
• Fast execution: We ship, measure, and iterate
• Technical excellence: We solve complex problems with cutting edge research. Latency deltas matter; we profile until they disappear.

If you’re excited about any of the below verticals… We want to hear from you.

• Designing High-frequency systems
• Forking Agave/Jito to build a new client that hosts bulk stack
• Building cutting-edge distributed systems
• Contributing to making markets better by building the best CLOB.

We’re not just building another L2 CLOB - we are pioneering the future of defi through the pinnacle of distributed systems. Your work will impact the future of market structure, enabling the true ethos of defi without sacrificing decentralization or performance.

We offer competitive compensation, significant equity, and the chance to solve problems that matter. Don’t just watch markets evolve - build it with us.

About the Role

We are seeking an exceptional Engineer to join our core team building critical, next-generation infrastructure and exchange. You'll be exploring uncharted technical territory and building novel solutions across our stack:

Your duties will include;

• Implement proposed Orderbook, Propagation layer and Consensus Layer.
• Design and Implement risk kernels, clearing house, matching engine collaborating with quantitative.
• Implement Bulk T1 (orderbook) on solana core validator stack (jito-agave)
• Optimize validator consensus and execution (Agave & Firedancer forks) to boost throughput and reduce latency.
• Profile and optimize pathways on our Order Propagation Layer, Consensus layer, Matching layer -> goal is to reach 200k+ orders/sec.

Background preference

If you have experience in any of the following, you may be a good fit:

• Firmware, Compilers

• Operating Systems Trading systems

• HFT

• Embedded Systems

• Networking Systems

Requirements

• 3+ years of systems-level programming in C, C++, or Rust (we use Rust). Bonus if you’ve built and scaled an orderbook.
• Obsessed with progress, not just activity; eager to dive deep, root-cause issues, and learn.
• Clear, concise communication; high agency; passion for DeFi and high-performance systems

This role comes with an extremely competitive overal compensation package, including bonuses and token allocation.
