Current location: About the Role

We are looking for a Development Lead to own the engineering of a core module within our observability platform, focused on discovery, monitoring, and performance management of networking devices and infrastructure (routers, switches, firewalls, load balancers, wireless controllers, and related network/IoT endpoints). This is a hands-on technical leadership role: you will design and build high-throughput data collection and processing pipelines, lead a team of engineers, and set the technical direction for how the platform monitors, correlates, and alerts on network health at scale.

The ideal candidate has deep experience building monitoring/NMS (Network Management System) style products or modules — comparable to the engineering work behind commercial network and infrastructure monitoring platforms — and is equally comfortable writing production Python code and guiding architectural decisions.

Key Responsibilities

Lead design, development, and delivery of network device discovery, polling, and monitoring capabilities within the observability platform.

Design and develop scalable data collection pipelines (polling, streaming, and event-driven) capable of handling large device inventories and high-frequency metric ingestion.

Drive engineering decisions around polling engines, protocol handlers, MIB/OID management, topology mapping, and alerting/thresholding logic.

Lead, mentor, and grow a team of Python developers; conduct code reviews, design reviews, and enforce engineering best practices.

Ensure the platform's collectors and agents are resilient, secure, and performant across heterogeneous vendor devices and firmware versions.

Collaborate with QA, DevOps, and Support teams to ensure reliability, observability of the observability stack itself, and fast root-cause turnaround for field issues.

Evaluate and integrate recent protocols, data sources, and third-party MIBs/device packs as network technology evolves (SD-WAN,



wireless, cloud-networking, IoT/OT).

Participate in sprint planning, estimation, and stakeholder communication; report on progress, risks, and technical trade-offs to senior leadership.

Maintain a strong security posture across credential handling, encrypted transport, and role-based access for device communication.

Domain & Protocol Scope

Candidates should have hands-on experience developing against or integrating with the following network management and telemetry protocols/standards:

SNMP (v1/v2c/v3): GET/GETNEXT/GETBULK polling, trap/inform handling, MIB parsing and compilation, custom OID mapping.

Flow-based telemetry: NetFlow, sFlow, IPFIX for traffic analytics and bandwidth monitoring.

Syslog: RFC 3164/5424 ingestion, parsing, and correlation for event and log-based monitoring.

ICMP: Ping/traceroute-based reachability and latency monitoring.

CLI-based collection: SSH/Telnet automation and screen-scraping for devices lacking API/SNMP support.

NETCONF/YANG and RESTCONF: Structured configuration and state retrieval from modern network devices.

WMI/WinRM: Windows-based server and infrastructure monitoring.

Topology discovery protocols: LLDP, CDP for physical/logical network mapping.

REST/SOAP APIs and gRPC: Vendor and cloud-provider integrations (firewalls, wireless controllers, SD-WAN controllers, public cloud networking).

Streaming telemetry & modern observability standards: OpenTelemetry, Prometheus exposition format/remote-write, StatsD, gNMI (desirable).

IoT/OT telemetry (desirable): MQTT, TR-069/CWMP for CPE/customer premise device management.

Time-series and event pipelines: Kafka, RabbitMQ, or similar for high-volume metric/event streaming.

Familiarity with routing/switching fundamentals (BGP, OSPF, VLANs, STP) and general network engineering concepts is expected,



even though the role is development-focused rather than network operations.

Required Skills & Experience

10+ years of professional software development experience, with at least 5 years in a technical or engineering lead capacity.

Strong, production-grade Python development skills: asyncio/concurrency patterns, performance optimization, packaging, and testing (pytest or equivalent).

Demonstrated experience building or extending network monitoring, NMS, APM, or observability products/modules.

Solid understanding of SNMP and at least two additional protocols listed above, with real implementation experience (not just conceptual knowledge).

Experience with time-series ,columnar and graph databases (e.g., Prometheus, InfluxDB, OpenTSDB, Clickhouse, Neo4J) and metric storage/query patterns at scale.

Practical experience with containerization and orchestration (Docker, Kubernetes) and CI/CD pipelines.

Strong Linux systems knowledge; comfortable with networking fundamentals (TCP/IP stack, DNS, routing).

Experience with relational and NoSQL data stores, and designing schemas for large-scale telemetry data.

Track record of leading small-to-mid-sized engineering teams (4-10 engineers), including hiring, mentoring, and performance management.

Strong written and verbal communication skills; ability to translate between deep technical detail and business/product priorities.

Preferred / Nice-to-Have

Experience with additional languages relevant to agent/collector development (Go, Java, or C/C++).

Exposure to public cloud networking services (AWS VPC/Transit Gateway, Azure VNet, GCP networking) and their native monitoring APIs.

Familiarity with anomaly detection, baselining, or ML-assisted alerting techniques applied to network/infrastructure metrics.

Experience with ITSM/ITOM integrations (ticketing, CMDB sync, event correlation with tools like ServiceNow).

Prior work on agent-based and agentless monitoring architectures, and plugin/extensibility frameworks for third-party device support.

Security certifications or hands-on experience with secure credential vaulting, TLS/mTLS, and role-based access control for device communication.
