Application Support Engineer II (Dev & AI Tech Enthusiast)

We are looking for an Application Support Engineer II with a developer's mindset and a passion for AI-driven efficiency—someone who looks at a Tier‑2 bug and wants to read the source code to understand why it broke.

Responsibilities

• Deep‑Dive Troubleshooting: 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; isolate Tier‑3 bugs, assist in database structural changes, and deploy toolsets that keep our global platform stable.
• AI & Automation First: lean on your tech curiosity and AI‑driven tools (e.g., AI coding assistants, 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.

Qualifications

• 1 to 5 years with a background in software development, technical application support, or a strong programming foundation (Junior Developer profiles are highly welcome).
• Developer Mindset: can read code, understand logic, and navigate databases.
• Tech Stack: our ecosystem runs on Ruby on Rails, Java, and React, backed by MySQL, MongoDB, Redis, and RabbitMQ.
• AI Curiosity: actively experiment with AI tools, prompts, or automation scripts to supercharge efficiency and solve technical puzzles faster.
• Communication: fluent in English.
• Bonus: previous experience in FinTech, the payments industry, or handling database structural changes.
