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:

We want our team to feel like owners because they are owners. We trust our people to manage their results and their time.

• Meaningful Equity: Every "Safestar" is a shareholder. You aren’t just an employee; you are a partner in our success.

• Unlimited Leaves: We don’t believe in clock-watching. We offer unlimited leave because we trust you to take the time you need to recharge while staying committed to the mission.

• Comprehensive Benefits: We provide top-tier medical insurance and wellness benefits to ensure you and your family are well cared for.

• Career Trajectory: We are growing aggressively. For high-performers, the path for advancement moves at the speed of your ambition.

Role Overview:   We are looking for an SDE II – Sensors to build customer-deployed security software that runs inside enterprise environments and continuously discovers assets, evaluates exposures, and securely communicates telemetry back to SAFE.
This role is suited for engineers with strong C++, Go or Python programming skills, Windows/Linux, networking, and cybersecurity fundamentals, particularly those who have worked on endpoint agents, security sensors, network/security products, or other long-running system software.

What You'll Do:

• 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.

What We're Looking For:

• 3–6 years of software development experience, preferably building systems, infrastructure or security products.

• Strong programming experience in one or more of C++, Go or Python.

• Strong understanding of Windows/Linux and operating-system fundamentals.

• Good understanding of networking concepts, including:

• TCP/IP and sockets

• DNS

• HTTP/HTTPS

• TLS

• Proxies

• Routing

• NAT

• Firewalls and network segmentation

• Experience with multithreading/concurrency, asynchronous programming and inter-process communication.

• Understanding of software security and secure communication practices.

• Ability to troubleshoot issues independently across code, OS and network boundaries.

Strongly Preferred:

• 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.

What Good Looks Like:

You should be comfortable going beyond:

"The API returned an error."

and investigating: Sensor → process → socket → DNS → proxy/firewall → network → cloud service to determine exactly where and why something failed.

You should be equally comfortable reasoning about:

• Why is a process consuming excessive CPU or memory

• Why communication works in one customer network but fails in another

• How to safely upgrade thousands of deployed sensors

• How to recover when a sensor loses connectivity for several hours

• How to execute security scans without destabilising customer infrastructure

• How to collect enough diagnostics to troubleshoot systems you cannot directly access

The ideal candidate is fundamentally a systems/security engineer who can build reliable software, rather than a conventional CRUD/backend application developer.

If you’re passionate about cyber risk, thrive in a fast-paced environment, and want to be part of a team that’s redefining security, we want to hear from you! 🚀
