A quick run-down of the job

We're looking for a Lead Security Architect to own and elevate security across the entire company. This is a hands-on, senior leadership role responsible for defining our security strategy, strengthening security practices, and driving solutions across our infrastructure, applications, and internal systems.

This role is responsible for security across the company, with a particular focus on application security and emerging Web3 and AI-related security risks. You'll set the direction for how our teams build securely, strengthen the security posture of our products, identify vulnerabilities, and introduce scalable security processes and tooling.

We're looking for someone who can quickly understand our systems, identify risks, and drive action - not just produce reports. You'll also coordinate external audits and build security awareness across the company. You'll work closely with engineering, AI, automation, and operations teams, and collaborate with our existing security architect to strengthen security practices across the company.

• Stay current on the evolving Web3 threat landscape and ensure the organisation is positioned ahead of emerging risks

What makes a Good Candidate

We're looking for someone who combines strategic thinking, strong judgment, and the technical credibility to lead across engineering and leadership

Experience

• Proven experience owning or leading a security function — not just executing within one

• Background in security engineering or architecture — you understand how systems are built and where they break

• Experience building or maturing security programmes in fast-moving engineering organisations

• Experience in a Web3 or payments fintech environment
  

Technical knowledge

• Strong understanding of modern application security practices

• Experience with security reviews, threat modelling, and vulnerability management

• Familiarity with cloud infrastructure security and developer tooling

• Understanding of AI security risks and emerging attack vectors is a strong plus

• Experience managing or mentoring security teams is a plus
  

Mindset

• Strategic thinker who can translate risk into priorities and communicate them clearly to leadership

• Comfortable operating with autonomy in a fast-moving, ambiguous environment

• Able to influence without authority across engineering and leadership

• Proactive by default - you identify problems before they're escalated to you

• Comfortable getting into the detail when the situation calls for it

Company culture

• Embracing the differences

  • Embrace your own differences

  • Respect and welcome the unique qualities of others

  • See others’ differences as an opportunity to grow

  • Hold yourself to a high bar for execution

  • Make bold decisions, and be accountable

  • Understand your limitations and seek for help

• Fail forward

  • Try - don’t be afraid to fail

  • Learn - don’t make the same mistake twice

  • Adapt - grow with the experience

• Have fun together

  • Take the time to get to know and understand each other better

  • Don’t take yourself too seriously and keep it light-hearted

  • Fun should be coming from a place of love and respect

• Annual company offsites — we've explored Thailand, Vietnam, Morocco, and Greece together. Next stop for 2027: TBD!

• 30 days of PTO

• Flexible remote days

• Flexible working hours

• Equity participation from day 1

• Entitlement to work computer (choice of equipment)
