Head of Security

As Head of Security at Helius, you own security across the company and lead it hands-on, doing the work yourself while building toward a team. You report to the COO and Head of Engineering, and the leadership team will depend on you to understand, manage, and make clear calls on risk. You have real authority and a clear mandate to protect a company operating critical infrastructure at scale on Solana.

What you'll do

• Lead security at Helius, setting direction and owning execution across infrastructure, cloud, and production systems
• Own incident response end to end: detection, response, runbooks, on-call readiness, and regular tabletop exercises
• Establish a strong security posture across the engineering platform, including identity and access management, secrets and key management, network segmentation, logging, monitoring, and detection
• Review and manage third-party and supply-chain risk
• Partner with engineering to embed security into how you build and ship, without becoming a bottleneck
• Lead the compliance roadmap and respond to customer security reviews
• Hire, develop, and grow the security team as the company scales
• Own the security strategy and roadmap, and maintain the threat model and risk register, prioritizing against real risk
• Communicate clearly about risk with executives, engineers, and customers

What you bring

• 8+ years in security, including experience securing high-availability, internet-facing infrastructure at scale
• Strong engineering skills: you read and write code and can dig into systems yourself
• Deep expertise in cloud security, bare metal, and production environments
• Hands-on experience with detection and response, and you have led through a real security incident
• Experience building a security program or significantly scaling a security function
• Experience securing developer products, APIs, or platforms
• A strong grasp of secrets and key management
• Comfort moving fast, iterating, and making good decisions under pressure
• Pragmatic, high-ownership mindset: you do the work and don't wait for a large team or established tooling
• Clear communication skills: you can partner with engineers and say no without being a blocker
• Comfort working in a fully remote, async-friendly team

Nice to have

• Experience leading a SOC 2 or similar audit
• Prior security leadership at a high-growth startup

What we offer

• Market-leading salary and meaningful equity
• Generous vacation and wellness budgets
• Support for learning and travel
• Fully remote, flexible work environment
