Stealth Cybersecurity Startup – Backend Engineer

About the Role

Seasoned Backend Engineer with a proven track record of delivering mission-critical systems in high-stakes, early-stage environments. Expert at navigating the "zero-to-one" phase, specialising in transforming ambiguous product requirements into robust, high-performance distributed systems that serve as the backbone for scaling startups.

Driven by a hybrid mindset, I balance deep technical execution with high-level architectural influence. I am focused on building secure, resilient, and developer-friendly infrastructure, ensuring that every line of code contributes to a scalable foundation for long-term growth.

Key Responsibilities

• Own the end-to-end lifecycle of core backend services, from initial architectural design to deployment and production monitoring.
• Design and implement scalable, low-latency APIs and microservices that support complex data flows and high-concurrency user demands.
• Develop sophisticated data schemas and optimize database performance to ensure data integrity and system responsiveness under heavy load.
• Lead the integration of third-party security protocols and internal identity management systems, maintaining a "security-first" approach to development.
• Ship high-quality, production-ready code in rapid iteration cycles, consistently meeting aggressive milestones without compromising on system stability.
• Influence the technical roadmap by identifying architectural bottlenecks and proposing modern, cost-effective solutions to improve system throughput.
• Collaborate across the engineering team to establish best practices for testing, CI/CD, and asynchronous documentation.

Skills and Experience Years of Experience: 4+ years in backend-heavy roles, specifically within the Cybersecurity or SaaS sectors. 

Core Tech Stack:

• Backend: Go, Python, Node.js.
