About the role

Senior Platform Engineer at Kilvin, an AI-native software agency that builds custom internal tools for non-technical teams, delivering via Kilvin's platform. High-ownership role shaping core infrastructure, multi-tenancy, and AI-assisted tooling.

Responsibilities

  • The app runtime and workspace - how custom apps are deployed, isolated, and served to clients inside a single secure environment.
  • The build & deploy pipeline - the AI-assisted system that takes a user request from requirements to specs to software to working software.
  • Multi-tenancy and access control - tenant isolation, fine-grained permissions (who can open which app and see which data), and the auth model underneath it.
  • Integrations - a framework for connecting client apps to CRMs, spreadsheets, email, and databases they rely on, so data moves between systems.
  • Reliability & observability - monitoring, performance, and tooling to run many production deployments with confidence.

Qualifications

  • 6+ years building and operating production software, with meaningful time spent on platform, infrastructure, or backend systems.
  • Strong fundamentals in distributed systems, data modeling, and API design.
  • Experience with multi-tenancy, auth/permissions, or sandboxing.
  • Experience with LLM orchestration or AI-assisted code generation in production.
