[Hiring] Senior Platform Engineer @Filigran

Role Description

We're looking for a Senior Platform Engineer to join our Platform Engineering team and help us run, secure, and scale the infrastructure behind the XTM Platform, Filigran's open-source platform for agentic Continuous Threat Exposure Management (CTEM).

• Design, build, and operate production Kubernetes clusters, on our own bare-metal infrastructure and on public clouds.
• Roll out and operate Filigran products in new regions and on new providers as our SaaS footprint expands.
• Develop and maintain the ways our products get deployed, by us and by our customers:
  • Helm charts (including a major rework of our charts)
  • Ansible automation
  • CI/CD pipelines
  • A virtual appliance for on-premises environments
• Keep our SaaS instances available and reliable, and continuously improve how we run them: observability, monitoring, capacity planning, incident management, and post-incident reviews.
• Harden the platform and help it meet the requirements of regulated environments (such as FedRAMP and SecNumCloud).
• Use AI agents throughout your daily work (writing infrastructure code, investigating incidents, drafting runbooks) while staying accountable for everything you review and ship.
• Help design the playground for agents: make our repositories, documentation and guardrails agent-friendly, so other teams can contribute safely, and regularly step back on what works and what needs to improve.
• Take problems from first signal to shipped solution: scope them, propose an approach, and document your decisions so others (humans and agents alike) can build on them.

Qualifications

• 5+ years of experience as a Platform Engineer, SRE, DevOps or Cloud Engineer.
• Hands-on experience running Kubernetes in production: operating and troubleshooting clusters, not just deploying to them.
• Strong Ansible skills and experience writing and maintaining Helm charts.
• Solid Linux and networking fundamentals.
• Comfortable working on at least one major cloud provider (AWS, Azure, GCP…), or strongly willing to learn.
• Experience with CI/CD pipelines (GitHub Actions or similar) and an observability stack (Prometheus, Grafana…).
• A security mindset: you think about secrets, access, network exposure and blast radius by default.
• An AI-oriented mindset: you already use AI tools and agents in your work, or you're eager to start, and you review their output with a critical eye.
• Willingness to code: no specific language is required, but you'll read and write scripts and tooling (mostly Python).
• Comfortable in a remote-first, asynchronous team, with a strong sense of ownership, autonomy and team spirit.
• Full professional proficiency in English.

Requirements

• Experience with bare-metal or on-premises infrastructure, where you handle networking, storage, and the cluster lifecycle yourself.
• Terraform, especially for cloud infrastructure.
• Infrastructure security experience (hardening, software supply chain, vulnerability management) or a CKS certification.
• Experience with regulated or compliance-heavy environments (FedRAMP, SecNumCloud, ISO 27001…).
• Operating backing services such as Elasticsearch, RabbitMQ, Redis or S3-compatible storage.
• Hands-on experience designing skills, workflows or guardrails for AI agents.
• Fluent in French.

Benefits

• Competitive compensation + equity — everyone shares in our success.
• Remote-first flexibility — work from wherever you’re based, with flexibility built into how we operate.
• 25 days PTO baseline — real time to disconnect, recharge and enjoy life outside work.
• Volunteer days — paid time to contribute to causes that matter to you.
• Set up for success — choose the equipment that works for you, with additional support for your remote work and development needs as our programs evolve.
• Two annual in-person get-togethers — one global company get-together and one team get-together, creating dedicated time to connect, collaborate and strengthen our culture beyond the screen.
