About The Position

We are seeking a Senior Software and Architecture Engineer for a hybrid position, preferably based in New York City, though strong candidates on the East Coast will be considered. This role requires an engineer with over 15 years of professional experience who is comfortable taking the lead, owning architectural decisions, setting technical direction, and mentoring teammates while remaining hands-on. Experience with CTEM is a plus. The ideal candidate values continuous learning, has a genuine interest in cybersecurity, and communicates clearly. Our current services are built on Django (Python) and React (TypeScript), hosted on AWS, with many more services to be developed. This is a startup environment where adaptability and a proactive approach are essential. We are looking for a relentless go-getter who thrives under pressure, moves with urgency, and makes quick, correct decisions. Strong communication and close collaboration with penetration testers and the business are paramount. If this energetic environment excites you, you will fit right in.
