We are looking for a talented and creative Senior 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 Web/Browsers research in the team.
Research new methods and mechanisms for collecting data, design and develop for the SDK, making it bulletproof and highly performant, and push the new features value in the organisation.
Research the ins and outs of Browser APIs and how they work under the hood, investigate lesser known features and understand upcoming new features.
Take ownership of the entire data flow process - from concept to implementation.
Collaborate closely with analytics and engineering teams to produce value for the company.
Deliver and deploy the SDK to thousands of merchants, 100M+ users every day, making sure its safe, stable, does not interfere with user experience, or website functionality.
Make sure we keep up to date with all the latest browser technologies and changes, important Web standards, features and protocols, security and privacy requirements etc.
Requirements: What you'll need:
6+ 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.
Basic data querying and analysis skills (SQL, Spark - Advantage).
Fluent in written and spoken English.
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.
