Cryptio

Cryptio is an enterprise-grade crypto back-office platform. Our software helps financial institutions, corporates, and crypto-native companies navigate the fragmented digital-asset landscape with confidence. We’ve raised $26M to date and are backed by tier-1 investors including Point Nine, 1kx, BlueYard, Tim Draper, Alven, and Ledger Cathay. Some of our clients include Circle, Uniswap, and the Government of El Salvador.

We’re tackling one of the biggest challenges in crypto today - building the infrastructure that will enable institutional adoption. And we’re playing to win.

Location

Although this is a remote-first role, we’d like to find someone who is based in the UK with easy access to our hubs in London and Paris.

The Role

We’re looking for a Head of Security; a pragmatic engineer who will own security across our product, infrastructure, and organisation. This is a hands-on builder role, not just governance or policy. You’ll be deploying tools, writing code, setting up processes, and helping us pass audits, sometimes all in the same quarter.

You’ll work closely with engineering, product, and operations to bake security into everything we do. This is an opportunity to take ownership of the security function from day one and grow it into a broader leadership role as the company scales.

What You’ll Be Doing

• Secure CI/CD pipelines, container workflows, infra-as-code, and deployment tooling
• Define and enforce access controls, auditing, and logging for internal services
• Evaluate and manage security tools (EDR, vulnerability scanners, SCA, etc.)
• Own and manage internal authentication (SSO, MFA, identity lifecycle)
• Secure endpoints, laptops, and internal systems
• Lead security awareness and employee training programs
• Drive SOC 1/2 and other compliance frameworks
• Build internal security policies, playbooks, and operational processes
• Manage relationships with vendors, auditors, and pentesters

We’re Looking For Someone Who Has

• 5+ years of hands-on experience in security engineering, ideally in a SaaS environment
• A CISSP or similar certification
• Strong knowledge of cloud security, secure software development, and common vulnerabilities
• Proven experience securing production environments and CI/CD systems
• Familiarity with security compliance frameworks (SOC 2, ISO 27001)
• Experience deploying and operationalising security tools
• Excellent communication skills and the ability to collaborate across teams
• A pragmatic, system-oriented mindset that balances risk and speed

Interview Process

2. 1st Interview – 60 minutes with Lucas (Senior Product Engineer)

3. CTO Interview – 30 minutes with Lukasz

4. Final Interview – 30 minutes with Antoine (CEO/Co-founder)

Benefits

• Fully-Remote / Hybrid – The choice is yours!
• 25 Days Paid Holiday + Bank Holidays

• Earn an extra day of annual leave for every year you’re at Cryptio
• Access to Mental Health, Wellbeing, and Coaching
• Attractive Maternity and Paternity Policies
• Gym Classes or Spa Treatments with ClassPass (or gym reimbursements)
