Helius is an equal opportunity employer.

We’re seeking a highly skilled Senior/Staff Backend Engineer passionate about solving complex problems and motivated to shape the MEV landscape on Monad with high-performance solutions. In this role, you will help design, build, and optimize MEV-related infrastructure, with a focus on block building, transaction ordering, and low-latency execution strategies etc. You’ll work on systems at the intersection of blockchain, trading, and networking, helping to advance the frontier of MEV innovation.

What You’ll Do

• Design and implement performance-critical backend systems for MEV infrastructure throughout the transaction lifecycle.
• Contribute to the development of infrastructure for validator-client integration, relay communication, and block propagation.
• Optimize code for latency, throughput, and reliability in adversarial network conditions.
• Stay informed about MEV developments in Ethereum, Solana, and other ecosystems

What We’re Looking For

• 4-10 years of backend programming experience with expertise in low-level languages like C++ and Rust (experience in both is a plus, but not required).
• Proven backend engineering experience in MEV infrastructure, trading/searching, or block-building organizations.
• Experience designing production-grade, low-latency, high-performance networking architecture and distributed systems.
• Proven track record of technical leadership and project ownership from start to finish.
• Ability to work autonomously in a fast-paced, collaborative remote environment with strong ownership.

Nice to Have

• Familiarity with blockchain internals and validator client behavior.
• Contributions to open-source MEV infra or tooling projects.
• Experience in performance tuning and networking stack optimization.
• HFT experience.
• Academic background from a top-tier university and/or experience at a well-regarded technology company

Why Join Us

Work at the frontier of crypto and DeFi infrastructure Join a tight-knit, low-ego team with deep technical chops Competitive compensation, bonus and token upside Fully remote, flexible work culture

Why This Role Matters

You’ll be our first engineering manager. You’ll lead a world-class team of engineers across multiple product lines and be the technical backbone and organizational glue that helps us scale while maintaining our fast-paced, high-impact culture.

What You’ll Do

• Lead a team of backend and systems engineers.
• Set a high technical bar: Lead design reviews, challenge assumptions, and guide architecture of distributed systems, low-latency services, and high-throughput APIs.
• Hire and grow the team: Own hiring end-to-end for your team with support from founders and recruiting.
• Work closely with founders to scale the company’s engineering culture, processes, and infrastructure.
• Execute fast in a demanding environment: Tradeoffs, uncertainty, pressure—we embrace it all.
• Drive impact on real crypto infrastructure used daily by top Solana teams and protocols.
• Split your time:
  • 60% engineering management (planning/execution, hiring, team health)
  • 25% technical leadership (system design, mentorship)
  • 15% coding (unblocking critical paths)

You’ll Thrive Here If You…

• Bring 1–2+ years of engineering management (startup or high-growth org) and know when to coach vs. dive in.
• Possess 5+ years of backend / systems engineering (Rust, Go, C++, or similar) and can still jump into code for a well-scoped fix or prototype.
• Have shipped and operated distributed, performance-sensitive systems (queues, caches, databases, pub/sub, low-latency services).
• Are comfortable hiring, coaching, and occasionally parting ways to keep the bar high.
• Communicate crisp trade-offs under pressure and keep teams laser-focused on outcomes.
• Care deeply about developer experience and impacting the Solana & crypto ecosystem.
• Are excited to shape Solana and broader web3 infra alongside an ambitious team.

Nice-to-Haves

• Production Rust expertise.
• Prior work on infra, DeFi, exchanges, or other high-throughput environments.
• Familiarity with Solana internals or web3 developer tooling.

What We Offer

• Competitive comp and equity.
• Fully remote + flexible work (core overlap with Americas time zones).
• Tight-knit, ambitious team with low ego and high ownership.
• A rare chance to shape the future of crypto.

We believe great managers amplify engineers. If you get energy from removing blockers, growing people, and occasionally rolling up your sleeves to unblock a launch or patch a critical bug, let’s talk.

Compensation Range: $250K - $300K

Waku is part of the Logos tech stack, a movement supporting the development of the decentralised web.
