The Infrastructure team under Apstra owns and evolves the backend infrastructure for Apstra.

Join a team where systems and data engineering converge

Youll work at the core of a high-performance, custom-built infrastructure platformwhile also helping shape the data pipelines that power our next-gen cloud analytics stack. This role offers rare dual exposure: from low-level optimization in performance-critical systems, to hands-on feature development in in-house time-seriesand graph databases. Youll contribute to building and refining connectivity for these databases to the cloud, driving real-world data flows across hybrid environments. If youre excited by deep infrastructure, data-intensive workloads, and full-stack thinking, this is where your impact multiplies.

What youll do:

1. Core Infrastructure (60% of Role)

• Maintains and enhances the backend platform that powers Apstraconfiguration, telemetry, and analytics pipeline.

• Owns:

  • Product packaging, upgrades, and deployment orchestration

  • Homegrown file-based telemetry database (custom-built, optimized for performance)

  • Distributed querying, data merging, system calls, IPC

  • Python + C++ hybrid execution, including C-extensions for performance

2. Data Engineering (40% of Role)

• Enables data synchronization from on-prem Apstra to on JCloud.

• Constructs data pipelines and ETL flows to prepare, transform, and deliver telemetry for downstream cloud analytics consumers.

• Owns cloud enablement and sync logic (e.g. examples datasets, format normalization, usage signals).

Why Candidates Should Join This Team

Youll Build Real InfrastructureNot Just Configure It
This isnt infra as codeitinfrastructure as a product. Youll design, scale, and optimize distributed systems that support real-time, multi-version enterprise network workloadsacross campus, data center, and WAN fabrics. Itinfrastructure that directly powers next-gen cloud analytics.

Hybrid Challenge: On-Prem Meets Cloud
Few roles offer this blend: deep low-level systems workcoupled with forward-looking data engineering. Youll help bridge Apstraon-prem legacy with its evolving cloud-native future, working across environments to modernize and integrate.

Deep Ownership + Technical Core
This team doesnt just connect APIs. It owns the architecturebehind Apstraanalytics and telemetry enginescritical infrastructure that underpins Junipermost advanced networking insights.

Custom Database Engineering + Analytics Edge
Youll work directly on our in-house telemetry database, focusing on:
