About the Role We’re hiring our first Head of Security. You’ll own security across Helius and lead it hands-on: doing the work yourself across our engineering platform while building toward a team. You’ll report to our COO and Head of Engineering, and our leadership team will depend on you to understand, manage, and make clear calls on risk.

Your priorities are to establish a strong security posture across our engineering platform and to own incident response. You’ll have real authority and a clear mandate to protect a company operating critical infrastructure at scale.

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 our 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 we build and ship, without becoming a bottleneck

• Lead our compliance roadmap and respond to customer security reviews

• Hire, develop, and grow the security team as we scale

• Own the security strategy and roadmap, and maintain our threat model and risk register, prioritizing against real risk

• Communicate clearly about risk with executives, engineers, and customers

What We're Looking For

• 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’ve led through a real security incident

• Experience building a security program or significantly scaling a security function

• Experience securing developer products, APIs, or platforms

• Strong grasp of secrets and key management

• Comfortable moving fast, iterating, and making good decisions under pressure

• Pragmatic and high-ownership: you do the work and don’t wait for a large team or established tooling

• Clear communicator who can partner with engineers and say no without being a blocker

• Comfortable 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

Why Helius?

• High-impact work: Your code will power applications used by millions across the Solana ecosystem, including Coinbase, Jupiter, and Phantom.

• Serious engineering: Build fast, reliable systems across distributed infra and high-throughput backends.

• Ownership & growth: Lead critical initiatives, influence architecture and product direction, and take on more responsibility as the company scales.

• Remote-first flexibility: Work where you’re most effective with a flexible, fully distributed team.

• Competitive comp & perks: Market-leading salary, meaningful equity, generous vacation, wellness budgets, and support for learning and travel.

• Mission-driven team: Join ambitious builders who move fast, take ownership, and are shaping the future of decentralized apps.
