About the Role

As a Protocol Research Engineer at Raiku, you’ll dive deep into Solana’s consensus mechanisms, validator dynamics, and block-building edge cases to help push the boundaries of what’s possible on-chain. 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.

Infrastructure & DevOps Engineer at Raiku

As an Infrastructure & DevOps Engineer at Raiku, you will lead critical engineering efforts that drive the performance and scalability of next-generation distributed systems. You’ll join a highly proficient team of core engineers, all of whom have contributed to foundational and novel infrastructure innovations.

We believe in hiring exceptional individuals who are deeply motivated by complex core infrastructure challenges and guided by a coherent system design philosophy that moves our industry forward. Expect frequent group discussions on architecture, design specs, and code reviews. We ship quality code quickly and often — and we are deeply committed to it.

About Raiku

Raiku is reimagining Solana’s transaction and consensus ecosystem by enabling validators to connect directly with purpose-built execution environments. Our platform delivers unprecedented performance, guaranteed transaction inclusion, and deterministic settlement for the next generation of internet-native applications. We unlock radical bandwidth and latency improvements by shifting Solana’s focus to efficient state verification — enabling high-velocity, reliable applications at massive scale​.

About the Team

Our entire platform is built in Rust, connecting Solana’s L1 with advanced L2 extensions and enabling deeply complex network interactions. Your primary focus in this role will involve Rust systems programming, infrastructure architecture (e.g., Kubernetes), and operational scripting across languages such as Rust, Go, and Typescript. Full-stack understanding — from bare metal to application interfaces — is critical to success here.

What You’ll Bring

• 4+ years of experience in infrastructure engineering, preferably within high-standard fintech, data, cloud, or DevOps environments.
• Senior-level experience as an SRE or Infrastructure Engineer with a strong Kubernetes background.
• Deep proficiency with Infrastructure as Code tools (Terraform/Terragrunt) and infrastructure automation (Helm, GitOps).

• Languages: Rust, Golang, Typescript, PostgreSQL
• Smart Contract Development: Anchor, Solana Program Library (SPL)

Preferred Qualifications

• Experience operating validators on distributed networks.
• Active engagement with the blockchain security research community, through open-source contributions, publications, or speaking at conferences.

Benefits

• Competitive compensation packages based on ongoing market analysis, including tokens.
• Remote-first culture with flexible hours — self-initiative and independence are highly valued.
• Work with highly talented engineers passionate about building the future of the internet.
• A collaborative and dynamic work environment that rewards individual ownership and impact.
• Opportunities for rapid professional growth within one of the most technically ambitious projects in web3.

Nimbus is a research team that focuses on developing an Ethereum client and library. We believe that the largest deployment of Ethereum will potentially be on embedded systems and Nimbus is designed to perform well on embedded, mobile and generally resource-restricted devices.

Building the stack from the ground up, we’re translating the latest Ethereum research into practical, performant and reusable libraries to provide a fertile exploration ground for further R&D.

About Nomos

Nomos is a new blockchain designed from the ground up with the original cypherpunk ethos: decentralisation, censorship resistance, permissionless-ness and privacy. It will serve as the trustless agreements layer of the Logos stack. The forthcoming Nomos network will provide a common infrastructure layer upon which communities and aspiring network states can build social, governance, and financial services that uphold their community members’ fundamental rights and values.
