Software Development Engineer II – Sensors / Systems & Security Engineering

Most boards and executives are currently flying blind when it comes to cyber risk. They are guessing. At Safe, we’ve built an AI-driven engine that finally gives the C-Suite a clear, quantified, and real-time view of their security posture. We don’t just provide data; we provide certainty.

We are a $170M Series C-funded category leader. We don’t play in the mid-market; we operate at the highest levels of global enterprise. Today, we are proud to serve 10% of the Fortune 500, protecting global icons such as Apple, Netflix, AT&T, Verizon, and Victoria’s Secret.

As we scale toward our next chapter, we are looking for high-performers who want to do the best work of their careers at the intersection of AI and Cybersecurity.

The Culture Memo: Our Operating System

Safe is not a typical corporate environment. We are a high-intensity, mission-driven team. We value builders who want to define a category and work alongside people who are equally committed to excellence.

• Extreme Ownership: We don’t do "not my job." We hire people who see a gap and own the solution from start to finish.

• The Elite Standard: We serve the most sophisticated companies on the planet. Our work must be bulletproof. Whether it’s a line of code or a sales deck, we aim for Tier-1 quality every time.

• Methodology & Rigor: We don’t wing it. From Force Management and MEDDICC in sales to data-driven sprints in engineering, we rely on proven frameworks to stay disciplined and predictable.

• Radical Candor: We move too fast for politics or sugar-coating. We value direct, honest feedback that helps us find the right answer quickly.

• The Series C Hustle: We have the stability of a well-funded leader but the heart of a startup.

The Perks & Ownership:

• Design and develop lightweight security sensors/agents running inside customer environments.

• Build capabilities for asset discovery, network scanning, vulnerability detection and exposure validation.

• Develop reliable, long-running system software with a focus on performance, resource usage, concurrency, and stability.

• Work extensively with Windows/Linux internals, processes, sockets, filesystems, networking and system APIs.

• Build communication between distributed sensors and the SAFE cloud with secure authentication, encryption, retries and offline recovery.

• Implement sensor lifecycle management, including installation, configuration, health monitoring and software/rule updates.

• Debug complex issues spanning application code, operating systems, customer networks, proxies, firewalls and infrastructure.

• Build strong diagnostics, telemetry and logging so problems can be investigated without requiring direct access to customer systems.

• Participate in low-level and high-level design discussions and independently own well-defined components/features through production.

• Experience building endpoint agents, sensors, collectors, daemons or system services.

• Experience working on cybersecurity, endpoint security, vulnerability management, micro-segmentation, EDR or network security products.

• Experience building software deployed across large heterogeneous enterprise environments.

• Familiarity with CVE, CVSS, vulnerability scanners and exposure management.

• Experience with secure auto-update / software distribution mechanisms.

• Familiarity with containers and technologies such as Docker and Kubernetes.

• Experience developing software that needs to operate reliably across Windows and Linux environments.
