Who are we?

HarfangLab is a cybersecurity scale-up, and we have developed an Endpoint Detection and Response (EDR) software to detect and mitigate modern cyberattacks on a company's workstations and servers. Our algorithms detect abnormal behaviors and generate security alerts or block program execution.

From 50 employees in 2023 to 115 as of now, HarfangLab is experiencing hypergrowth and has already achieved several significant milestones: winners of the Ministry of Defense's cyber challenge in 2019, recipients of the BPI's I-Nov competition in 2020, and software certified by ANSSI in 2021.

Our initial clients include CAC40 industrial companies and government entities. We completed our first funding round of €5 million in 2021 and our second funding round of €25 millions in 2023, which will enable us to strengthen our teams, and to expand internationally in Europe.

Our mission is to protect businesses and government agencies from modern cybersecurity threats (cybercrime, data theft, influence) that endanger the economic health of companies and the security of the nation.

What Will You Do With Us?

We’re a cross-functional team handling both build and run tasks, so your missions will be varied and impactful.

Here’s what you can expect to work on:

• Build and Improve the Product: Add new features and enhancements to make it even better.
• Optimize CI/CD Pipelines: Collaborate with developers to ensure the pipeline is as efficient as possible, using GitLab-CI, Kubernetes (K8s), Helm, KubeVirt, and a suite of complementary tools.
• Automate Client On-Premise Installations: Help with initial deployments and develop automation to make subsequent setups seamless. We use Ansible, k3s, Helm, and some custom Python code.
• Monitor and Maintain Internal Cloud and Infrastructure: Ensure smooth operation, fix issues, and automate repairs across our internal cloud stacks.
• R&D for New Tools and Frameworks: Stay ahead of the curve by researching and experimenting with new technologies that could benefit our team.
• Be On-Call When Necessary.

What Are We Looking For?

Hard Skills:

• Strong knowledge of Kubernetes and containerd/Docker.
• Proficiency with Linux systems and Git.
• Familiarity with a CI/CD toolchain.
• Solid bash scripting skills.
• Coding skills (preferably in Python or Go).

Bonus Skills:

• Experience with Ansible or other Infrastructure-as-Code tools (e.g., Puppet, Chef, Terraform).
• Knowledge of Virtual Machines.
• Expertise in Monitoring/Observability (e.g., Prometheus, Datadog, CloudWatch).
• Familiarity with Cloud Platforms (e.g., OVHCloud, AWS, GCE).
• Security knowledge (network, system, or container security).

Soft Skills:

• Ability to clearly communicate your progress and ideas.
• A team player who thrives both in-person and remotely.
• Curiosity and a knack for keeping up with the latest tech trends.
• Strong sense of confidentiality.
• Thoughtful problem-solving: better to spend a day researching a solution than rush into a quick fix you might have to undo.

What Can You Expect From Your Manager and Team?

You’ll join a 6-person team where everyone contributes across the board. As with all teams at HarfangLab, we enjoy significant autonomy and make decisions collectively whenever possible.
