We're looking for a builder with a backend backbone--someone who can spot an opportunity, sketch a solution, and ship a working service fast. You'll turn AI ideas into production-grade APIs and microservices, then iterate based on real data and feedback.
You'll work at the edge of what's possible with LLMs, RAG pipelines, and vector-based retrieval. The mission: wire up smart systems that automate workflows, elevate productivity, and make AI feel less like magic and more like reliable infrastructure.
Get the tools to grow globally at . Follow: , , ,

• In this role you'll:
• Design, build, and scale backend services and RESTful APIs that power AI features.
• Train, deploy, and maintain ML models--especially in NLP and deep learning contexts.
• Stand up and iterate on LLM-driven apps, including RAG pipelines and vector-store retrieval.
• Own end-to-end delivery: prototyping, evaluation, deployment, monitoring, and iteration.
• Define clear KPIs, run experiments, and optimize based on what the data says.
• Collaborate with product, data, and engineering to turn ideas into shippable systems.
• Stay current on the LLM ecosystem and quickly put new tools and methods to work.

Requirements:
What you'll need:

• 4+ years of professional software development experience with a strong backend focus
• Proven track record building and deploying AI/ML models (NLP/deep learning)
• Hands-on expertise with RESTful APIs and microservices architecture
• Practical experience with : LLMs, RAG pipelines, or vector-store-based retrieval
• Excellent communication, a bias for action, and comfort working in fast-moving teams

Bonus points for

• Solid grounding in data-science fundamentals (statistics, preprocessing, feature engineering)
• Experience integrating generative models with external knowledge via RAG
• Proficiency with embeddings and vector databases (e.g., FAISS, Pinecone)
• Working knowledge of LLM workflows: prompt engineering, inference, fine-tuning, and evaluation
• Familiarity with Agile practices and a habit of staying on top of the latest AI research and tools
