Full Job Description
Join a fast-growing global leader in cybersecurity, trusted by some of the biggest names in the industry. Besides many enterprises and government agencies, nearly 30% of the world’s top MSSPs rely on our platform, and that number is growing every day as more companies recognize the value of next-generation security solutions. We're at the forefront of protecting organizations against sophisticated cyber threats using cutting-edge AI and automation technologies. We offer a highly competitive compensation package on par with industry leaders like Google and Microsoft, ensuring our team is rewarded for their expertise and dedication. We are fully remote, providing the flexibility to work from anywhere in Taiwan or Japan. We are rooted in transparency and openness, without rigid hierarchies. We are feedback-driven, encouraging open communication and innovation at every level. Our culture is built on diversity, openness, and collaboration, fostering creativity and innovation that drives real impact in the market. Stellar Cyber is looking for a Senior or Staff Software Engineer to own parser development on our Automation-Driven Open & Unified SecOps Platform (powering our AI-driven SIEM, NDR, Open XDR, and Multi-Layer AI). Parsers are the front door of our platform—every security event from firewalls, endpoints, cloud logs, and SaaS tools flows through the components you build before it can be detected, correlated, or acted on. The quality, coverage, and performance of your work directly shapes what the rest of the platform can see. Stellar Cyber needs someone who treats parsing as an engineering domain to own, not a ticket queue to grind through—someone who can independently drive the parser framework forward, pick up new log formats and vendor quirks quickly, make sound design decisions on schema and normalization, and raise the bar for the engineers around them. We move fast, give engineers real autonomy, and embrace AI not just in our products but in how we build them
