About the role
We’re looking for an experienced systems software engineer to help drive and evolve our product. This person would extend and own our on-endpoint network proxy solution, intercepting and manipulating the network traffic of third party software. Our technology is new and rapidly evolving, and you’ll have a chance to be an early contributor with a substantial impact on the product architecture.
What you'll do
Hook or redirect outbound connections, terminate and re-establish TLS sessions, and apply content-aware policies in real time
Add low-level collectors that trace data flows across apps, files, sockets, and pipes, feeding a unified event stream
Solve challenging performance optimization problems: we’re building software that monitors hundreds of thousands of events with minimal impact on performance of the endpoint applications
Design and build highly reliable code that never impacts the end-user experience
Build secure-by-design hardened software that must withstand real-world attacks, while processing untrusted data and communicating with a backend over the internet
Who you are:
Strong track record in network interception and parsing
Prior work on at least one forward proxy used by security software
Experience debugging, profiling, and optimizing the performance of low-level system software
Proficient in designing and implementing application architecture
Experience with agile development and SCRUM
Proven ability to collaborate with a distributed cross-functional team
Possess verbal and written communication skills in English
Availability to frequently communicate with a distributed engineering team in Central European and US Eastern time zones.

What We Do
Cyberhaven was founded by computer scientists and security experts from MIT and EPFL to rethink data security. Instead of stopping threats at the perimeter, we trace the full lineage of sensitive data, where it originates, how it moves, and who uses it. This breakthrough became the foundation of our data lineage platform, now powering Cyberhaven’s leadership in data detection and response and protecting enterprises from insider threats and data loss.
Our Data Detection and Response solution transforms how enterprises protect their data with a unique technology called data lineage. Cyberhaven records every event for every piece of data – every move, copy, edit, and share to fully understand how data moves throughout your company. We developed an architecture that achieves complete visibility of your data, including as it transits unmanaged cloud apps and unmanaged devices.
As data moves throughout your company, from person to person and application to application, it fragments and gets combined with other data. We calculate the lineage for every piece of data starting with its origin through every step it takes. Our product allows you to define what is risky for your organization, enforce actions to protect data, and educate your workforce in real time.
Why Work With Us
Cyberhaven is a Series D unicorn in AI-driven data security, protecting 300+ customers like Motorola, Reddit, and Snowflake. We solve next-gen DLP by tracing full data lineage and enabling real-time insights. As a value-driven company with remote and hybrid work, you’ll grow alongside bold thinkers, making real impact.
