A zero-instrumentation observability solution that automatically discovers services running on each host. It supports both plaintext and TLS-encrypted traffic, classifies Layer 7 protocols, decodes service-level communication, and reports RED metrics (requests, errors, duration). By leveraging low-level user and kernel APIs, the team captures comprehensive signals from the system. Beyond networking, they tackle complex challenges such as protocol versioning, TLS detection across varied languages and runtimes, and ensuring robust performance in production environments.
We're looking for a senior engineer with strong systems-level thinking and deep familiarity with Windows. You should be comfortable working close to the kernel - ideally with experience in kernel development, or a strong desire to get there. Proficiency in C/C++ is essential; experience with Go is a plus. A solid understanding of networking protocols and TLS internals is highly valuable.
Youll join a high-impact team tackling ambitious technical challenges - like decoding traffic across multiple protocols, and ensuring high-fidelity metrics in complex, real-world environments. Youll be expected to lead design and implementation efforts, contribute to roadmap planning, and collaborate across teams to ensure our solution remains robust, scalable, and frictionless for our users
This role is a great fit for engineers who thrive on low-level, performance-sensitive problems, and want to shape the future of observability through cutting-edge kernel technology.
we place value in our office culture - the relationships that it builds, the creativity it brings to the table, and the collaboration of being together. We operate as a hybrid workplace to ensure our employees can create a work-life harmony that best fits them.
What Youll Do:
Own new feature development end-to-end from ideation to implementation
Build low-overhead data collection tools based on Windows kernel drivers that collect important metrics from the kernel and in particular the network stack
Develop systems to auto-discover services, classify L7 protocols, and extract RED metrics from both plaintext and TLS traffic
Solve complex challenges around protocol parsing, encryption handling, and performance at the kernel level
Collaborate across teams to drive technical direction, improve reliability, and scale the system for production use
Requirements: You have in depth knowledge with C/C++ and Windows OS kernel development
You have strong low-level Windows OS internals knowledge
You have experience working with and developing in the Windows operating system, developing and troubleshooting kernel drivers (using WFP, Win 32 APIs, DDK, )
You have a deep understanding of the various layers of the network protocol stack and have hands-on experience troubleshooting networking or API related issues
You have significant experience building high throughput/low latency systems
You are motivated by solving problems for our customers first and foremost and building beautiful products that our customers love
This position is open to all candidates.
