CodiLime engineers work within the platform's Assurance & Integrations area, building and extending the integrations that connect the platform to third-party network systems and controllers - such as Cisco Meraki, VMware vCenter, Juniper Mist, and Infoblox. These integrations run as lightweight discovery agents that securely connect to a customer's infrastructure, continuously identifying devices, interfaces, and the relationships between them. The discovered data is then delivered through the platform's declarative data ingestion API. The platform is built AI-first, with its own Claude Code agent skills and MCP server, and that mindset carries over to how the team works: AI-assisted development is actively cultivated day to day to help the team move fast and consistently land high-quality results.
