Upwind is a next-generation cloud security platform that uses runtime context to identify, prioritize, and remediate the most critical risks in cloud environments. By leveraging eBPF-powered sensors and real-time runtime data, Upwind goes beyond traditional cloud security tools, providing precise risk prioritization, actionable posture insights, and effective threat protection. Our platform delivers end-to-end cloud infrastructure security, including agentless posture management, real-time threat detection, and integrated API security, enabling teams to focus on what truly matters while maintaining high efficiency and cost-effectiveness. At Upwind, you’ll join a fast-growing company where creativity, ownership, and impact are part of the day-to-day work, and where your contributions directly shape the future of cloud security.

We are looking for a Software Engineer to join our team and help build advanced security capabilities for macOS environments. In this role, you will design and develop macOS-native components that operate close to the operating system, working on deep integrations with OS internals, networking, and system-level security frameworks. You will collaborate closely with security researchers, backend engineers, and platform teams to build high-performance, reliable, and secure systems that protect cloud and endpoint environments at scale.

Responsibilities:

• Design, develop, and maintain macOS native security components operating close to the operating system
• Work with low-level OS internals, including networking, file systems, and system events
• Build high-performance and reliable software for security and monitoring use cases
• Integrate macOS components with cloud-based security services
• Collaborate closely with security researchers, backend engineers, and platform teams
• Participate in architecture decisions and contribute to scalable, data-intensive systems
• Ensure code quality, performance, and security best practices throughout the development lifecycle

Requirements

• US or EU citizenship / valid work permit
• Bachelor’s degree in Computer Science, Software Engineering, or a related field
• 3+ years of software engineering experience in a high-level programming language (e.g. Golang, Rust, Swift, C, Java)
• 2+ years of experience developing macOS native applications
• Strong understanding of operating system internals, networking, and file systems
• Experience with cloud platforms such as AWS, GCP, or Azure
• Experience building data-intensive systems (databases, event systems, messaging systems, etc.)

Nice to Have

• Experience with macOS Endpoint Security Framework
• Experience with macOS Network Extensions
• Experience working with eBPF
