(If you have core programming skills in any language and are excited to hack away at these, you're a match). * AI Curiosity: You actively experiment with AI tools, prompts, or automation scripts to supercharge your efficiency and solve technical puzzles faster. * Communication: Fluent in English. You'll be collaborating daily with cross-functional engineering teams worldwide. * Bonus Points: Previous experience in FinTech, the payments industry, or handling database structural changes. ## Description * Deep-Dive Troubleshooting: Don't just route issues; open the hood. Triage and resolve Tier-2 internal application bugs by analyzing code behavior, system logs, and data flows. * Bridge to Core Engineering: Work hand-in-hand with core backend/frontend squads. You'll isolate Tier-3 bugs, assist in database structural changes, and deploy toolsets that keep our global platform stable. * AI & Automation First: We hate repetitive tasks. You will lean on your tech curiosity and AI-driven tools (like AI coding assistants and LLMs) to automate workflows, build scripts, and optimize our support infrastructure. * Architect Documentation: Translate complex system behaviors into clean, technical documentation for Tier-1 teams and internal alignment. ## Related Videos - [Your next 10x engineer isn't in your city.
