About KAST

KAST is redefining what it means to bank with stablecoins – think Revolut, rebuilt from scratch on Web3. Backed by top-tier VCs, we’ve grown from 0 to 1 million users in under a year. We’re building the next-gen global bank based entirely on stablecoins.

Design is at the heart of everything we do – it’s how we simplify the complex, make money feel easy, and turn crypto skeptics into brand ambassadors.

KAST is redefining what it means to bank with stablecoins — think Revolut, rebuilt from scratch on Web3. Backed by top-tier VCs, we’ve grown from 0 to 1 million users in under a year. We’re building the next-generation global bank powered entirely by stablecoins.

Security is foundational to everything we build. Our mission is to make digital banking safe, transparent, and trustless — without sacrificing speed or innovation.

The Role

We’re hiring a Security Lead to build and run the security function at KAST — spanning governance, engineering, and operations.

You’ll set the standards, design the architecture, and build systems that balance startup velocity with banking-grade security. From cloud hardening to third-party risk assessments, from incident response to compliance readiness — you’ll own it, build it, and grow it.

You’ll work directly with leadership to shape security culture, lead audits, and define the controls that protect both users and the company.

This role is broad by design — combining GRC, SecOps, and technical depth. It’s for someone who thrives on variety, handles pressure, and makes bold decisions with clarity.

What You’ll Be Doing

  • The owner of KAST’s security posture — from code to compliance
  • The architect of secure infrastructure, integrations, and resilient systems
  • The link between engineering, compliance/risk, and leadership
  • The person who ensures “secure by design” is the default, not the afterthought

What You’ll Bring

  • 10+ years in tech, covering multiple domains (engineering, GRC, architecture, operations)
  • Experience in fintech or crypto/blockchain/web3
  • Proven ability to design and implement secure systems across cloud, network, and app layers
  • Experience leading audits, compliance programs, or risk management frameworks (ISO 27001, SOC 2, etc)
  • Strong technical grounding in cloud security (AWS/GCP), containerization, CI/CD, and identity systems
  • Demonstrated ability to lead teams and influence culture, not just enforce controls

Why KAST?

  • Define what “secure banking” means for the stablecoin era
  • Lead from first principles — not playbooks
  • Work with a world-class team building a real financial product, fast
  • Remote-first, high-trust culture with true ownership and autonomy
  • Competitive comp + meaningful equity upside

How To Apply?

  • Referrals only, find your way in
  • Ask someone from the KAST team to vouch for you
  • Show us what you’ve built that proves you’re world-class
  • Or surprise us — the best builders always do
