About the role

Senior Software Engineer responsible for designing, building, and operating the AI Platform's shared services (agent and MCP infrastructure, evaluation pipelines, and AI observability) to accelerate AI feature delivery while meeting security, cost, and quality standards in a cybersecurity-focused environment.

Responsibilities

  • Design, build, and operate services of the AI Platform, such as evaluation pipelines, agent and MCP infrastructure, and observability tooling.
  • Lead small-to-medium features from technical design through completion, working independently within a clear roadmap.
  • Ensure the platform is reliable at scale, including testing, monitoring, on-call participation, and postmortems with root cause analysis.
  • Collaborate with product and feature teams adopting the platform, at times building customer-facing AI features alongside them, and turn their needs and pain points into platform improvements.
  • Share knowledge across the team through code reviews, documentation, and mentoring less experienced colleagues.

Qualifications

  • 5 or more years of experience building backend services and distributed systems running in production.
  • Strong coding skills in a mainstream backend language, such as Python or Java, and working experience with Kubernetes and cloud infrastructure.
  • Experience building with LLMs, including model API integration, retrieval, agents, or evaluation tooling; production experience is a strong plus, and demonstrated personal projects also count.
  • Operational maturity, having owned services in production, including monitoring, debugging live issues, and incident response.
  • Experience shipping customer-facing product features is preferred.
  • Experience in cybersecurity or another regulated or high-trust domain is preferred.
