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
