Who we are?

HarfangLab is a cybersecurity scale-up that has developed an EDR (Endpoint Detection and Response) software, designed to prevent, detect and neutralize attacks targeting workstations and servers. In 2024, our solution has incorporated EPP (Endpoint Protection Platform) capabilities and monitoring tools to simplify IT infrastructure audits.

Since our founding in 2018, HarfangLab's technology has earned widespread recognition, winning prestigious awards and achieving the distinction of being the first ANSSI-certified EDR in 2020, followed by becoming the first to receive ANSSI qualification in 2025.

We have raised a total of €30 millions, enabling us to strengthen our teams and expand internationally across Europe. In just three years, HarfangLab’s workforce has nearly tripled, with the majority of its team members coming from technical backgrounds and dedicating themselves to R&D and continuous product enhancement.

Today, HarfangLab protects the endpoints of several hundred clients of all shapes and sizes, from CAC 40 corporations and government agencies to SMEs, hospitals, and local councils.

Driven by a strong sense of teamwork and global ambitions, HarfangLab continues to grow while staying true to its mission: to protect organisations from increasingly sophisticated cyber threats while ensuring that customers maintain full control over their data.

What you will do with us?

You will join the Product Division, which represents 60% of the company and brings together all the teams contributing to the development of our EDR. You’ll be part of the Front-End team, currently made up of 8 people working on the development of HarfangLab’s web application. You’ll collaborate regularly with other teams, including Back-End, Agent, AI, DevOps, CTI, QA, etc...

Your missions will include:

• Designing and developing new features: Harfanglab continuously strives to create new features to provide the most professional cybersecurity application for its clients. These features are developed and deployed using agile methods to ensure that the user experience remains the best in the market.
• Ensuring scalability: The code of the web application must remain simple, readable, and scalable to continue to adapt to the needs of the clients.
• You will mainly work with Vue3 using SASS.

What you can expect from your future team?

You will join a team of passionate engineers who are committed to continuously improving our product. Like every team at HarfangLab, we value autonomy and mutual trust. Do you think something needs to be improved, a new library tested, or a feature added? Propose it — and make it happen. We also hold bi-monthly meetings to share updates from the front-end ecosystem and discuss newly developed features.
