Description

  • Design and build core security primitives and services that protect MongoDB Atlas compute, networking, and identity across AWS, Azure, and GCP.
  • Build secure-by-default infrastructure using Linux security mechanisms, Kubernetes, and eBPF to enforce runtime policies and improve system visibility.
  • Develop APIs, automation, and tooling to manage security posture at scale, including CSPM, vulnerability management, and workload identity.
  • Create monitoring, logging, and alerting pipelines that integrate with internal tooling such as Grafana, Splunk, and Victoria Metrics.
  • Integrate security controls into CI/CD and infrastructure-as-code workflows using Terraform so they are versioned, reviewed, and deployed like application code.
  • Lead complex projects end to end, from problem discovery and design documentation through implementation, rollout, and long-term ownership.
  • Collaborate with SRE, platform, and product engineering teams to define secure architectures for new infrastructure and services.

Requirements

  • 5+ years of experience in Software Engineering, Site Reliability Engineering, or a similar role, preferably with relevant security work.
  • Proficiency in at least one programming language such as Java, Golang, Rust, Python, or C/C++.
  • Experience with infrastructure-as-code tools, especially Terraform, to automate security configurations and processes.
  • Deep understanding of Linux and networking concepts, including low-level fundamentals and how they work together in complex systems.
  • Experience building security-related platforms or features such as runtime monitoring, CSPM, or vulnerability management.
  • Experience with at least one cloud provider, such as AWS, GCP, or Azure, and their security best practices.
  • Hands-on experience with Kubernetes and its security ecosystem, such as RBAC, OPA/Gatekeeper, Kyverno, eBPF, Falco, or Tetragon.
  • A systems mindset with attention to failure modes, performance, observability, and operability alongside security and correctness.
  • Strong communication skills and the ability to explain complex security concepts and tradeoffs to both technical and non-technical stakeholders.

Benefits

  • Role can be based in MongoDB’s Dublin office or worked fully remotely in Ireland.
  • Supportive culture focused on employee growth, wellbeing, and personal and professional development.
  • Employee affinity groups.
  • Fertility assistance.
  • Generous parental leave policy.
  • Accommodation support for individuals with disabilities during the application and interview process.
