Software Frontend Engineer
HarfangLab · Paris · Télétravail complet
Publiée le 16 octobre 2026
Who we are?
HarfangLab is the European leader in Workspace Detection and Response, a new approach to protecting the digital environments where people work.
As organizations increasingly rely on cloud services, digital identities, connected devices and AI-powered tools, security teams often have to manage multiple, disconnected solutions. This fragmentation creates gaps in visibility and makes cyber threats harder to identify and stop.
HarfangLab brings these protections together in a single platform. Powered by lightweight software and AI designed specifically for cybersecurity, our technology helps organizations detect suspicious activity, investigate incidents and respond to threats across computers, servers, identities, email, cloud environments, internet-facing systems and AI tools.
Organizations can deploy our platform in the cloud or within their own infrastructure, allowing them to retain control over their technology and data. Our EDR was the first to be certified and qualified by ANSSI, France’s national cybersecurity agency, and the first EDR to receive certification from the BSI, Germany’s Federal Office for Information Security.Today, HarfangLab’s technology protects more than 1,000 customers across a wide range of sectors, from major corporations and public institutions to SMEs, hospitals and local authorities. Having grown from 40 employees in 2023 to 140 today, we now have teams working across several European countries.
As we continue to grow across Europe, we are looking for talented people to join our teams and support the next stage of HarfangLab’s development.
