About the role: As a Senior Python Engineer, become a part of a cross-functional development team engineering experiences of tomorrow. Project Description: The project focuses on developing a remote scanning engine capable of discovering IP-based devices across enterprise networks using a combination of network protocols and integration techniques — without requiring agents on target systems. Collected data is processed, enriched, and synchronized with a CMDB to support accurate configuration item management and infrastructure mapping. Responsibilities: Develop Core Scanning Logic: Write high-performance, concurrent code in Python or Go to handle large-scale network sweeps using Nmap, ICMP, and ARP Implement Agentless Interrogation: Build and maintain the modules responsible for remote data extraction via SNMP (v1-v3), WMI, and SSH to query diverse hardware without local agents Build Fingerprinting Heuristics: Create and refine logic for device identification, accurately mapping raw scan data to specific vendors, models, and firmware versions Engineer Data Pipelines: Develop backend processes for data normalization and deduplication, ensuring that messy network data is cleaned before it hits the database API Integration & Sync: Build and optimize RESTful APIs to push enriched configuration item (CI) data into the Xurrent CMDB, ensuring synchronization is reliable and performant Network Troubleshooting: Debug complex discovery issues related to TCP/IP fundamentals, such as routing hurdles, VLAN segmentation, and firewall blocks Cloud & Hybrid Discovery: Develop API-based collectors to bridge the gap between physical on-prem hardware and cloud-managed network devices Maintain Technical Documentation: Document protocol-specific quirks, discovery schemas, and API contracts to ensure the engine remains maintainable by the wider engineering team Requirements: Strong proficiency in Python and/or Go Solid understanding of TCP/IP networking fundamentals (subnets, VLANs, routing) Hands-on experience with network discovery and scanning protocols (Nmap, ICMP, ARP) Experience working with SNMP (v1/v2c/v3) for querying network devices (routers, switches, firewalls, printers) Familiarity with WMI for remote Windows system interrogation Experience with SSH-based discovery across Linux/Unix environments Experience integrating with REST APIs, including cloud-managed network devices Strong knowledge of device fingerprinting techniques (OS detection, vendor, model, firmware identification) Experience building data pipelines for deduplication and normalization Experience developing REST APIs for CMDB integration and CI synchronization Hands-on experience with CMDB integrations (CI creation, updates, conflict resolution, relationship mapping) Background in SaaS or product engineering environments is preferred Familiarity with tools such as Netdisco, OpenNMS, or JDisc is a plus What`s in it for you?
