About The Position

We’re looking for a Senior Software Engineer to build and scale the backend systems that power our AI agent. This role sits at the intersection of backend engineering, machine learning, and product, and is focused on turning AI capabilities into reliable, production-ready systems. You won’t be training models, but you will make them work in the real world. You’ll build APIs, services, and data systems that connect LLMs and ML models to user-facing experiences, ensuring performance, reliability, and scalability.

Requirements

5+ years of experience in software engineering, with strong backend focus
Strong proficiency in Python and experience building production-grade systems
Experience designing APIs and service-oriented architectures
Experience working with ML/AI systems in production environments (LLMs, ranking, recommendations, or similar)
Familiarity with databases (SQL and/or NoSQL) and data-intensive systems
Experience with cloud platforms (AWS, GCP, or Azure) and modern infrastructure
Exposure to containerization and orchestration (Docker, Kubernetes)
Ability to operate in ambiguity and take ownership of loosely defined problems
Strong product mindset with focus on real user outcomes
Clear communication and ability to collaborate across engineering, ML, and product

Responsibilities

Design and build APIs and backend services that power AI-driven product experiences
Develop systems that integrate LLMs and ML models into production workflows
Build and maintain data pipelines supporting training, inference, and evaluation
Partner closely with ML Engineers, Data Scientists, and Product to ship end-to-end features
Improve system performance, reliability, and scalability across services
Contribute to experimentation and feedback loops that improve model and product performance
Debug complex production issues and drive root cause resolution
Raise the bar on code quality, system design, and engineering standards
