AI Prompt Engineer (Codebase Modernization & Microservices)

We have a massive, battle-tested legacy codebase written in PHP and Python. It has served us well, but it’s time for its next evolution. We are decomposing this monolith into a modern, lightning-fast microservices architecture—and we are doing it by leveraging the full power of Generative AI.

We are looking for a hybrid Software Engineer & AI Prompt Engineer who knows how to orchestrate LLMs to refactor, translate, and modularize complex code safely and at scale. This isn't about just typing queries into ChatGPT; it’s about building automated AI pipelines that write clean, production-ready microservices.

What You Will Do

Architect AI Pipelines: Design, test, and optimize advanced prompt workflows and agentic chains (using frameworks like LangChain, LlamaIndex, or LangGraph) to automate code translation.
Deconstruct the Monolith: Analyze existing PHP/Python codebases and guide LLMs to split them into clean, decoupled microservices.
Build AI Guardrails: Develop automated testing and validation pipelines to ensure AI-generated code is secure, idiomatic, and bug-free.
Collaborate with Architects: Work closely with our senior backend engineers to define target architectures, API contracts, and data schemas.
Benchmark & Iterate: Continuously evaluate different LLMs (GPT-4o, Claude 3.5 Sonnet, DeepSeek, etc.) to find the best tool for specific refactoring tasks.

What We Are Looking For

Strong Software Engineering Foundation: You need to understand what good code looks like. Professional experience with Python is a must; familiarity with PHP (to read and understand the legacy code) is a huge plus.
Deep LLM & Prompting Expertise: Proven experience with advanced prompt engineering techniques (few-shot, Chain-of-Thought, program-aided language models) and building AI-driven agent workflows.
Microservices Mindset: Solid understanding of microservices design patterns, REST/gRPC APIs, and containerization (Docker/Kubernetes).
The "Hacker" Spirit: You love pushing the boundaries of what AI can do, but you also know when to step in and write code manually because "the robot is hallucinating."

What We Offer

The Ultimate AI Playground: Direct, enterprise-level access to the latest frontier models and AI tooling.
High Impact: You won't be fixing minor bugs; you will be shaping the core infrastructure of our next-generation platform.
Flexible & Remote-Friendly: We trust you to get the job done, wherever you work best.
No Bureaucracy: Quick decision-making, direct communication, and a highly collaborative team of tech enthusiasts.
