Python Engineer for API Automation & Integration

Backend Python Engineer – Automation Pipeline & API Integration (No Frontend) Please read carefully: This is strictly a backend and infrastructure role. We run a scaling digital goods marketplace that sells premium subscription API keys. We are currently processing around 50 orders daily, and we need to completely automate our fulfillment pipeline so we can scale higher without manual bottlenecks. You will be building the "glue" that connects our isolated backend systems into one automated, high-concurrency lifecycle running on a Linux VPS with a MongoDB database. The Pipeline Architecture: You will be writing the Python logic that bridges these three existing endpoints: The Creation Tool: Our internal system that generates the raw web accounts. The API Generator: A custom fork of sub2api hosted on our VPS. This converts the raw accounts into usable API keys. (We have already built the core functionalities here). The Storefront: The platform that receives the customer's order and delivers the final key. How It Needs to Work: When a customer places an order, your script must trigger automatically. It needs to pull a fresh account from the Creation Tool, pass it into our sub2api fork, generate the unique API key, and push that key back to the Storefront for delivery. The Technical Challenge: We need an engineer who understands state management and queueing. You must account for concurrency and failure states. If an account gets blocked during generation or an endpoint times out, your script needs to handle the error gracefully, flag the bad account, and retry with a new one without crashing the entire order queue. Tech Stack: Python (FastAPI / automation scripting) REST APIs & Webhooks Linux VPS (Background process management) MongoDB How to Apply: I am filtering out bots and copy-pasted cover letters. To be considered: Start your proposal with the exact word "Nightowl". Watch this short architectural explainer video so you know exactly what you are walking into: [login to view URL] In your proposal, give me a brief, no-nonsense explanation of how you would architect the queue system and error-handling logic between these three endpoints. Include one specific detail from the very end of the video linked above. I don't need a long cover letter about your past jobs—just show me you understand the logic required for this pipeline. Looking forward to your proposals!
