Here is the Helius Manifesto so you know what to expect if you join Helius.

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
