About the role

Senior AI-Driven Backend Engineer translating product needs into code at Trengo. Leading architectural evolution of PHP monolith into scalable microservices and focusing on high-speed execution.

Responsibilities

High-Speed Execution: You will translate product needs into working code immediately. You should be comfortable in an environment where the goal is a functional prototype running in production by the end of the day.
AI-Native Workflow: You will use **Cursor** and **Claude.ai** (including **Claude Code**) to handle the heavy lifting of code generation. Your focus stays on high-level architecture while the agents manage the implementation.
Architectural Evolution: You will lead the incremental change of our PHP monolith into scalable, event-driven microservices. You design systems resilient enough to handle the pace of AI-driven releases.
Agentic Logic: Instead of building static systems, you will focus on building AI Agents with specialized skills and connectors. This allows our technology to solve customer problems autonomously.
Outcome-Based Agility: We skip the heavy SCRUM overhead. We focus on engineering practices where the only metric that matters is how fast we deliver value to the customer.

AI-First Approach: You are an expert at using the latest tools to refactor modules and navigate complex codebases. You should be proficient with Claude Code to accelerate your workflow.
Backend Expertise: You have 5+ years of professional experience. Our stack includes **PHP, Node.js, Python, and Vue.js**. We value your ability to solve complex problems more than your knowledge of a specific syntax.
Beyond Infrastructure: You understand that the future is agentic. You know how to build the skills and connectors that allow AI agents to deliver value. You have moved past old RAG-based thinking.
Product Focus: You look for the shortest path to a solution. You would rather find a smart integration or a creative connector to solve a problem in an hour than spend a month building a custom solution from scratch.
Verification Mastery: Since AI writes the code, your value lies in your ability to verify the output quickly. You are the final gatekeeper for security, performance, and architectural integrity.
