I am partnering with an international (New York, Singapore) well-funded, analyst-recognised cyber security scale-up (nearly $30m raised) that helps large enterprises and critical infrastructure providers understand how they could be hacked in real time. Their platform blends threat intelligence, real attacker telemetry and automated red teaming to give security teams time to respond before attackers succeed.

• Design, build and maintain features across backend and frontend.
• Turn product and design requirements into scalable, high-quality code.
• Collaborate with product, design and engineering to deliver seamless user experiences.
• Solve challenges around performance, scalability and developer efficiency.
• Help improve engineering standards, tooling and processes.

The Person

• We are seeking two engineers, one mid-level and one Senior-level to build enterprise SaaS products across the full stack (cybersecurity experience is a strong plus).
• Backend: TypeScript, NestJS, REST APIs, GraphQL or similar ORM, MySQL and NoSQL, Kafka or similar.
• Frontend: React, Next.js, TypeScript, Chakra UI, React Query (or similar), GraphQL integration.
• Comfortable working with complex dashboards and data-heavy UIs.
• Able to interpret designs and flows from tools like Figma.
• Experience in startups or high-growth environments, with an ownership mindset and ability to thrive under pressure.

Nice to have : AWS, Kubernetes, and knowledge of infrastructure / networking.

Interview process : Technical exercise plus 2 stage remote video call.
