JOB DESCRIPTION

Python Developer (Sales Automation tooling)

Mission

Own and evolve our existing Python-based Vendor-Specific tools that support quoting, pricing and renewals. Keep them running reliably, adapt to vendor/API changes, and extend them so a single solution works across countries.

Scope of the current codebase (for handover)

• Vendor API client with token management (OAuth endpoints, token file persistence, refresh, error handling).
• GUI apps (CustomTkinter/Tkinter) for SKU extraction and operator workflows, incl. streaming to a local LLM service, SKU table, progress bars, and status messages.
• Pricelist tool: reads/caches Excel (openpyxl/pandas), manages config and auto-updates, resolves Product SKU variants (-EU/-B2B), and prepares outputs for downstream processes.
• Configuration & updates: JSON config with versioning, LLM URL, update paths (SharePoint-synced folder to local), Excel source/target, plus credentials placeholders for Product API.
• Token cache file for API auth (access/refresh/expiry).

Key responsibilities

1. Maintenance & reliability

• Keep the Product API client working (auth flows, token refresh, error handling, timeouts/retries).
• Ensure GUI apps run smoothly on Windows (packaging, icons, paths, file permissions).
• Maintain pricelist ingestion (Excel schema changes, caching, performance).

1. Adaptation to vendor changes

• Track Product API or data model changes and update request/response handling accordingly.
• Adjust SKU logic for new suffix/category rules.

1. Enhancements (if required)

• E.g.: Extend SKU extraction and validation logic; refine LLM integration (connection checks, streaming fallback).

1. Transition from the Python solution to the core IT integration

• Midterm: we will integrate the solution into our core IT landscape, and this requires input about the processes inside the solution.

Tech stack (must be comfortable with)

• Python 3.10+; requests, pandas, openpyxl, Tkinter/CustomTkinter, threading, json, pickle.
• REST APIs & OAuth
• Windows environment (paths, file permissions).

Relevant:

• Experience with Excel/PDF/email parsing at scale and performance tuning.
• Familiarity with NAV/Business Central data needs for quoting/renewals (to shape outputs).
• Basic LLM client integration experience (HTTP streaming, resilience).
