Senior Developer / Technical Lead

Company Description

StrongKeep is a Singapore-based cybersecurity startup reinventing how smaller businesses achieve security and compliance. We build an affordable, automated cybersecurity SaaS platform that integrates best-in-class open-source tools, smart defaults, and AI-driven automation — so small teams can achieve enterprise-grade protection.

Role Description

This full-time, on-site Senior Developer / Technical Lead role owns the technical delivery of StrongKeep's platform on a lean 7-person team. You will lead a small group of engineers, own our GEN 2 delivery and the Compliance module end-to-end, and set the bar for architecture, code quality, and shipping pace. You are equally comfortable writing the hard code yourself and unblocking the people around you.

A strong interest in AI (LLMs, GenAI, agentic workflows) is expected — we build AI-assisted development into our daily workflow (Claude Code and similar), and the product itself is moving toward embedded intelligence and automation.

You will work closely with a locally-based, multi-disciplinary team — engineers, a designer, a PM - mentoring junior engineers while staying hands-on yourself.

Software Development

Collaboration & Delivery
