Required skills

We’re looking for an experienced endpoint systems developer to help drive and evolve our product. 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.
- 2+ years of experience working with low-level system APIs on macOS (file system, network, process APIs), or experience with a similar OS and ability to learn macOS very quickly
- Prior work on at least one systems native application deployed to thousands of end-users
- Experience debugging and optimizing the performance of low-level system software
- Experience with Swift or ability to learn it very quickly
- Experience with agile development and SCRUM
- Excellent verbal and written communication skills in English
- Availability to frequently communicate with a distributed engineering team in Central European and US Eastern time zones

As a plus

- Experience building endpoint security products — such as DLP or antiviruses — this is a big plus!
- Experience designing and implementing application architecture
- Experience collaborating with a distributed cross-functional team

We offer

- Competitive salary, excellent benefits
- Equity grants — you will own a part of the company
- Working in an exceptionally strong team and opportunities to learn and grow professionally
- Having a real and visible impact on the technology, the company success, and ultimately, on stopping data breaches everywhere in the world
- English classes
- Flexible schedule
- Great office space and support to make sure you can comfortably work from either home or the office, depending on your preference

Responsibilities

You will be solving multiple exciting technical challenges, including:
- Design and implement components of our state-of-the-art system sensor that traces all data movement across all applications and files on desktop machines on macOS and takes action to prevent data exfiltration when needed
- Solve challenging performance optimization problems: we’re building software that monitors hundreds of thousands of events while using less than 1% CPU
- 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

Project description

We’re a Silicon Valley startup building technology that stops data breaches using a completely new approach that by far outperforms everything else that exists today, and are looking for experienced low-level systems developers. We’re recording millions of events per second from thousands of devices and collecting them in a large-scale cluster to reconstruct a complete graph of all data flows across entire companies, and then analyzing this graph in real-time to detect exfiltrations before they happen. Our product is already being used by companies like Motorola, Zoom, Western Digital, and future-looking agencies like DARPA (the one that builds AI robots and has created the internet!) to protect their most sensitive data.
