Software Development Engineer 2 – 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: 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. 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! 🚀
