Remote only
Founded in 2022, Filigran is a global cybersecurity company on a mission to empower defense teams to be proactive through open-source solutions that uncover threats and drive action.
Filigran stands out in the cybersecurity ecosystem through its open-source, AI-powered and threat-informed approach to Continuous Threat Exposure Management (CTEM). Our eXtended Threat Management (XTM) platform brings together threat intelligence, exposure validation and cyber risk reduction, enabling organizations to better understand their threat landscape and take action.
At the heart of Filigran is our open-source approach. Our vision is to unite defenders into a global community to make security more open, resilient and collaborative.
As Filigran continues to scale globally, we are building the organization, infrastructure and capabilities needed for our next stage of growth. How we scale matters just as much as how fast we scale: our CORE values: Cohesion, Openness, Responsibility and Equity shape how we work together, make decisions and build for the future.
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).
Our customer base keeps growing, in more regions and on more providers, and our platform grows with it: our own bare-metal Kubernetes cloud, the major public clouds, sovereign and regulated environments, and on-premises deployments for customers who run our products themselves.
You'll work across the whole platform, from Kubernetes clusters and deployment tooling to observability, security, and on-call, in a team that has made AI agents a core part of how it works.
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, and 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
You'll report to the Director of Platform Engineering
You'll join a collaborative, non-siloed Platform Engineering team of about fifteen people across three verticals, working closely with our Technical Product Manager and fellow platform engineers, including staff engineers
You'll work hand in hand with software development teams and customer support on reliability, scalability and the rollout of new products and features
On-call: a shared rotation of around one daytime shift and one night shift every two weeks, plus one weekend every six weeks or so. Night and weekend on-call is compensated.
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
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
