We are looking for a talented and creative Principal Security Researcher with experience conducting low and high level research on Browsers to join our Cyber R&D.
Our Javascript SDK runs on 100M+ users worldwide everyday. It collects advanced and unique digital intelligence data points that help us catch the bad guys. It is highly performant and maintains strict privacy standards, running on a very broad device and browser landscape.
Data points created by SDK feed our rich data aggregation and enrichment systems, allowing for extremely high and accurate decision making. Very high scale data streams produced by the SDK are handled by servers which are also written and maintained by our team, and youll take part in owning those systems too.
What you'll be doing:
Dive deep into browser internals, understand the low-level core components of Chromium and Webkit, and become an expert on the topic.
Lead browser and web research initiatives, setting direction and driving innovation across the team.
Design and build advanced data collection features in our SDK - ensuring performance, resilience, and privacy at scale.
Take ownership of the entire data flow process - from concept to implementation.
Collaborate with Engineering, Analytics, and Product teams to turn research into business value.
Act as a technical authority on browser technologies - mentoring others and shaping long-term strategy.
Ensure our SDK remains safe, stable, and effective across 100M+ users, staying ahead of browser and web standards.
Requirements: What you'll need:
7+ Years of proven hands-on work research or development experience with modern technologies or frameworks.
Proven track record in applied technical research, experimentation, or in-depth technology analysis
Understanding of Cloud services, AWS, Kubernetes.
Experience working in large-scale production environments with real users.
Strong grasp of Computer Systems fundamentals: OS, Networking, Security.

A go-to person mindset, someone others rely on for support and solutions.
Curiosity and a passion for solving complex problems.
Creative thinking and a fresh approach to challenges.
A team-oriented mindset and love for collaboration.
It would be cool if you have:
Deep and broad knowledge of all things Web - JavaScript, HTTP, TLS, DNS, and browser internals (performance, security, APIs/features).
Hands-on experience with Web and browser research.
Familiarity with AdBlockers (on either side of the fence).
Experience working with non-mainstream browser APIs such as WebRTC, WebGL/WebGPU, WebAudio, PaymentRequest, WebAuthn, and others.
This position is open to all candidates.
