Senior Incident Response Engineer

As the leading provider of Cybersecurity-as-a-Service (CSaaS), RADICL is revolutionizing advanced cyberthreat protection for small and medium‑sized businesses (SMBs) in the U.S. Defense Industrial Base (DIB) and other regulated industries. No longer should SMBs be satisfied with lack luster solutions delivering lack luster protection. RADICL is ushering in a new era of turn‑key and affordable cyberthreat protection via its AI‑powered virtual SOC platform that allows human and digital agents to quickly and seamlessly become SMBs’ day‑to‑day compliance and security operations team.

RADICL’s turn‑key CSaaS offering uniquely combines compliance management with AI and expert‑driven 24/7 security operations. We guide customers to regulatory and best practice adherence with standards like CMMC and NIST CSF while also delivering 24/7 threat monitoring, deep‑spectrum™ threat hunting, incident response, vulnerability management, and security awareness training.

With RADICL, customers can stay mission focused, confident their front, rear, and flank are protected, affordably and without compromise.

If you’re excited about working with industry experts to help SMBs focus on growing their businesses without the constant worry of security and compliance risks, we invite you to join us in our mission to protect American businesses and drive innovation in cybersecurity.

We are looking for a Senior Incident Response Engineer to join our team. In this role, you will serve as a frontline expert and strategic driver of our IR capabilities —leading response to active threats across our customer base, building repeatable playbooks, and pushing the boundaries of how AI and automation can accelerate incident response at scale.

This is not a purely reactive role. You will help shape how we detect, contain, and remediate threats, while also educating and empowering our customers through tabletop exercises and IR readiness programs. For the right candidate, there is also a meaningful opportunity to help build and lead a retained incident response practice — expanding our offerings beyond MDR into a standalone, billable IR consulting capability.

If the above excites you, RADICL Defense is seeking high performing, motivated individuals to join our mission. As an early member, you will work closely alongside an experienced founding team and realize the life‑changing experience of building a company. You will work with the latest technologies in software, cybersecurity, and cloud and will have a significant impact on the formation of our platform and offering.

You enjoy fast‑paced environments, bring a positive attitude, and excel at getting things done. You enjoy being part of a high performing team and are also able to self‑direct and self‑start. You consider yourself to be top tier talent and are eager to help others raise their game. You enjoy working with customers, are an excellent communicator, and able to engage and interact with people of various backgrounds and skill levels.

You want your work to have meaning, to be important. You want to be part of creating something great.
