  • Partnering with Product Design to deliver intuitive, robust enterprise workflows
  • Tackling complex technical challenges across large-scale data pipelines, secure access, event-driven systems, and multi-tenant architectures
  • Embedding Agile, DevOps, and best practices into the engineering organisation

    • What they’re looking for:

  • 10+ years of experience building and managing distributed engineering teams across multiple regions
  • Proven track record as a global leader, managing local leads and scaling high-performing teams
  • Experience delivering enterprise-grade SaaS applications in a high-growth B2B environment
  • Strong technical depth across:
  • Backend: Node.js, Typescript
  • Frontend: React.js, Typescript
  • Database: MySQL
  • Cloud/Infra: AWS, ECS, K8s, Airflow, Kafka, Serverless
  • Solid understanding of SaaS fundamentals: onboarding, authentication, SSO, granular authorisation, multi-tenancy
  • Familiarity with workflow orchestration, asynchronous tasks, and event-driven architecture
  • Ideally, exposure to cybersecurity platforms or large-scale security data systems

    • Why join?

    ✅ Competitive compensation & benefits
    ✅ Key leadership role in a high-growth cybersecurity scale-up
    ✅ Opportunity to shape global engineering strategy and culture
    ✅ Work with cutting-edge technology solving complex, industry-wide challenges
    ✅ Endless career progression — growth and internal promotion are core to their DNA

    This is a rare chance to lead a global engineering function at a company reshaping how the world’s biggest organisations stay ahead of attackers. If you’re a proven applications leader with SaaS and security experience — this one’s for you.

    Apply now — your next big challenge starts here.
