AI works great in tutorials. We make it work in the real world.
At Core Reply, we operate at one of the most exciting—and least talked about—frontiers of generative AI: legacy modernization. Our clients run complex systems, decades-old architectures, and historical data environments that are anything but straightforward. Our job is to bring GenAI exactly where it creates the greatest impact.
If you have an AI-first mindset and aren't intimidated by real-world complexity, this is your opportunity.
What You'll Do
We don't start from scratch. We start from real enterprise systems—complex, established, and sometimes challenging—and transform them with GenAI as the primary driver.
This means getting your hands dirty: working with Java, Python, legacy architectures, and production constraints. But you'll do it while leveraging LangChain, LLMs, and AI pipelines as part of your everyday toolkit. It's precisely this combination that makes our projects unlike anything you'll find elsewhere.
Depending on your level of experience, you'll work on:
Developing and deploying GenAI solutions in enterprise environments
Integrating LLMs into existing systems and architectures
Backend development with Java and/or Python
Optimizing AI algorithms and system performance
Building internal tools that support the software development lifecycle
Producing technical documentation and sharing best practices
(For senior profiles) Mentoring team members and supporting team growth
Who We're Looking For
This position is open to junior, mid-level, and senior professionals. We're not looking for people who already know everything—we're looking for people with the right mindset.
Here's what you should know before applying: you'll be working in legacy environments, with enterprise-grade languages and architectures. That's not a limitation—it's where GenAI proves its real value. If you're looking for greenfield projects and perfectly curated datasets, we're probably not the right fit. If you enjoy solving problems that others struggle even to define, keep reading.
