Areas of Responsibility

You will be responsible for analyzing, designing, developing, and maintaining various frontend and backend Python and Go applications. These applications interact with the BICS telecom network and integrate existing commercial monitoring systems.

Typical applications include:

• Collecting, parsing, and enriching network data, then transferring it to the BICS Business Intelligence team or loading it into databases (e.g., Oracle, PostgreSQL) to build real-time dashboards or alarming frontends
• High-performance real-time distributed processing of network probing data feeds (50k+ records/sec) using packages like asyncio, PyPy, and Redis and being transitioned to Go
• Network monitoring-oriented database-driven applications with API-based backends using FastAPI and Ariadne (GraphQL) and frontend frameworks like React, or more traditional Django/Flask, HTML, JavaScript, CSS, and Oracle/Postgres (e.g., for planned works management, capacity planning, resources reservation, etc.)
• High-performance Go backend applications processing large volumes of data, reading/writing CSV or Parquet files, embedding DuckDB, exposing API endpoints for data query and instrumentation

These applications help BICS Operations teams work more efficiently by automating tasks and providing better visibility of the network status.

• Skills in using relational databases (Oracle, Postgres) as backends, writing SQL queries, extending data models, and utilizing ORMs and migrations
• Ability to work independently, learn business domain concepts, and engage directly with product owners and users
• Computer science background with the ability to make pragmatic design choices, select appropriate architectures and data structures (e.g., trees, deques, caches, circular buffers), and understanding of their computational complexity (O(n), O(n log n), etc.) and their resource usage (CPU, memory, network, disk, latency, etc.) and compromises
• Familiarity with CI/CD pipelines, with the ability to configure GitLab for running unit tests, building Python packages, and compiling Go binaries
• Commitment to best practices, producing idiomatic, maintainable code with unit tests, documentation, and structured packaging
