About

Sekoia.io repense la cybersécurité pour la rendre encore plus pertinente, efficace et accessible. L'un des principaux défis que nous relevons est d'analyser et de comprendre en permanence les menaces émergentes afin de définir des stratégies appropriées et d'avoir la capacité de les exécuter à grande échelle. En combinant la technologie et une équipe pluridisciplinaire de passionnés de Threat Intelligence, Sekoia.io a un fort impact sur la cybersécurité avec une approche qui brise les silos, qu'ils soient technologiques, organisationnels ou culturels.

Job Description

We’re creating a self-hosted SaaS platform designed for the most critical, regulated and air-gapped environments. As a Senior Frontend Engineer, you will design and deliver the operator-facing user experiences that make our Self-Hosted platform installable, observable, and operable by customers in highly constrained environments. Your mission is to build robust, offline-capable UIs that extend our SaaS DNA into self-hosted deployments.

📍 The position is available in Rennes, Paris or fully remote in Europe.

Your Missions

• Build a wizard-like installer/updater with preflight checks (CPU, memory, OS/K8s versions) that guides operators and fails gracefully on incompatibility.
• Develop UIs that let operators trigger diagnostics, capture logs/metrics/configs, and generate signed export bundles
• Ensure all UIs are offline-capable (service workers, caching strategies).
• Provide clear remediation guidance and runbooks integrated into the UI.
• Design a UI for browsing, staging, and applying signed offline bundles (CTI, AI models, detection rules) with pin/rollback and compatibility checks.
• Ensure design and component consistency with our SaaS product, while adapting flows to on-prem constraints.
• Work closely with Backend Engineers and SREs to keep UX aligned with deployment architecture.
• Provide a lifecycle management UI for one-click upgrades, rollbacks, and version pinning.

• You have a minimum of 5 years professional experience in front-end development, with strong experience with Angular.
• You are autonomous in your technological watch and you are up-to-date with latest standards
• You ensure code quality by following good development practices and strong test strategies. You are driven by simplicity & efficiency.
• You participate in code reviews and provide constructive feedback to team members.
