Head of Security

You'll be our first Head of Security. There's already a real foundation here—bug bounty, pen tests, automated code and configuration scanning on the production and code side, phishing simulations on the people side. You’ll add to it across access and identity, SecOps and monitoring, incident response, vendor security, employee security practices, and policy. You'll own the whole posture. This is a player-coach role. Early on, you'll do the scoping and the hands-on work yourself; this is not a role where you direct from above. As the work demands it, we're fully prepared to build a team here—and we're looking to you to define what that team should be and when.

Responsibilities

Own Tremendous' security posture end-to-end, partnering with our engineering team on production infrastructure and code security; Assess where we have gaps, prioritize them, and tackle our highest-leverage gaps first. We’ll have opinions, but you own the prioritization and implementation; Treat incident response as core, not afterthought. We may not be able to prevent a breach, but your job is making sure it's small, contained, and that we know exactly what to do; Drive security as a cultural shift across the company—introducing controls incrementally, working with teams rather than over them. "Yes, and," not "no"; Lead our AI-security posture. We invest heavily in AI tooling; your job is to manage that risk and enable it, not to ban it; Define when and how to staff up the security function, and hire your own team.

Requirements

Real, hands-on security experience at a company that scaled; Deep experience in at least one core security domain—product/production security, security operations, or access/identity and policy—with enough range to reason across the others; You defined the security posture, not just executed someone else’s playbook; An engineer's mindset. You reach for code to solve problems and can read our codebase and understand our infrastructure (Ruby on Rails; TypeScript + React; PostgreSQL; Google Cloud). You won't write much day-to-day, but you're not lost in the code; Judgment over checklists. You can explain the actual risk of a given decision, hold a firm line where it matters, and give ground where 'best practice' doesn't apply to us or real business need pulls the other way. You can hold your own in a debate about whether to open up broad data access for AI tooling; Bedside manner. You drive hard change by bringing the team around to your point of view, rather than just telling them no. Engineers and the rest of the company want to work with you.

Nice to have

Ideally as an early security hire who grew with the business through high growth; Experience building or co-building a small security team is a plus; Fintech, payments, or regulated-industry experience is a plus.

Benefits

You define the function. First security leader, with the budget for the required tools and team; A real mandate. The push for this hire comes straight from the founders; We invest in your tools. Everyone has a $5k/month budget for AI tools. Use it; Meaningful equity; Fully remote. Work from anywhere in the Americas; Great culture.
