Requirements
- 4–8+ years of experience in backend software engineering, ML/platform engineering, or similar roles.
- Strong proficiency in TypeScript/Node.js (our primary backend language), with strong API and microservice design skills. Working proficiency in Python is a plus for ML/model integration work.
- Hands-on experience building and operating production backend systems at scale — distributed systems, databases, message queues.
- Experience integrating ML or Generative AI models (LLMs, multimodal models) into backend services — inference, orchestration, and evaluation.
- Solid understanding of cloud infrastructure (AWS, GCP, or Azure) and containerization (Docker, Kubernetes).
- Experience designing and operating data pipelines (batch and/or streaming) across structured and unstructured data.
- Hands-on experience building retrieval-augmented generation (RAG) systems and AI memory architectures — retrieval pipelines, vector stores, context management, and long-term/session memory for LLM applications.
- Strong grasp of system design fundamentals: scalability, reliability, security, and observability.
