ABOUT DOUBLEZERO

DoubleZero is a decentralized, permissionless protocol that revolutionizes network performance for distributed systems like blockchain. The mission is simple: increase bandwidth and reduce latency.

DoubleZero increases bandwidth by filtering junk data that currently plagues validators and other network operators. DoubleZero reduces latency by connecting these filters with underutilized private fiber links in the form of a mesh network. By combining these improvements and routing the right data through optimized, low-latency paths, the DoubleZero protocol empowers blockchains and other systems to reach performance levels that are currently impossible.

In short, DoubleZero is a new Internet for distributed systems. It is supported by two organizations: DoubleZero Foundation, which drives the adoption, decentralization, security, and advancement of the protocol; and Malbec Labs, which develops the technical components of the protocol itself. We look forward to hearing from you.

Your work will directly inform and evolve Raiku’s infrastructure — including ahead-of-time auctions, deterministic inclusion, and decentralized execution environments.

This role is ideal for an engineer who obsesses over protocol-level behavior, from slashing conditions and fork choice rules to novel token incentive structures and inclusion guarantees. You will collaborate closely with our core engineering team, lead technical research deep-dives, and shape future SIMD proposals and Raiku-native designs.

Core Responsibilities

Protocol Research & Development

  • Analyze Solana protocol changes (SIMDs) and model their impact on consensus, block production, and validator incentives.
  • Explore alternative leader schedules, transaction scheduling policies, and failure recovery mechanisms.
  • Design and prototype changes to Raiku’s validator sidecar, ackermann-node, and execution environment logic.

Incentives & Economics

  • Simulate and reason about token-level economics (e.g. fee markets, slot auctions, stake redistribution) in the context of Raiku’s architecture.
  • Collaborate with the team on reward structures that align validators, apps, and execution primitives.
  • Contribute to internal tooling for simulating validator behavior under new fee models or coordination layers.

Research & Thought Leadership

  • Write internal memos and public-facing research exploring protocol edge cases, inclusion determinism, and priority fee market design.
  • Lead technical discussions and workshops across the team and ecosystem partners.
  • Represent Raiku in upstream governance and protocol forums (e.g., GitHub SIMDs, community calls).

What We’re Looking For

  • Deep understanding of Solana’s architecture, consensus algorithm (Tower BFT), and validator mechanics.
  • Proficiency in systems programming (Rust or C++) and experience working with validator or node clients (Agave, Jito, etc.).
  • Comfort reasoning about distributed systems, forks, slashing, transaction lifecycle, and fee markets.
  • Demonstrated ability to write clear, technical research — either internal design docs or public content.
  • A rigorous, systems-level thinker who thrives in ambiguity and wants to help shape the frontier of internet-scale consensus.

Bonus Points

  • Experience contributing to SIMD proposals or L1 protocol development (Solana, Cosmos, Ethereum, etc.).
  • Familiarity with execution environments (SVM, EVM, Move) or decentralized scheduling infrastructure.
  • Interest in MEV mitigation, slot auctions, or validator tokenomics.
  • Past experience in distributed systems research, zero-knowledge design, or compiler/runtime engineering.

Why Join Raiku?

Raiku is building a high-performance execution layer atop Solana that enables guaranteed transaction inclusion, pre-confirmations, and slot-level coordination — unlocking a new design space for ultra-reliable onchain apps. We’re backed by leading investors, deeply technical, and shipping fast.

  • Work with a world-class engineering team building core infrastructure from first principles.
  • Help define the next evolution of block production and validator coordination on Solana.
  • Remote-first, async culture optimized for focus, ownership, and velocity.
  • Competitive salary + meaningful token upside.
  • Home office and workstation setup stipend.
