Job summary

Bluehost is seeking an experienced backend engineer to design and scale async Python services, focusing on AI-enabled features and multi-agent workflows. You will integrate multiple LLM providers, build robust RAG pipelines, and own CI/CD from development to production.

Requirements include 5+ years in production Python backends with async I/O, REST API design, and experience with vector databases and AI-readiness. A self-starter mindset and ability to own architecture end-to-end are essential.

Qualifications

• 5+ years building production backend systems in Python with async I/O experience.
• Hands-on experience designing and scaling REST or async APIs with dependency injection and clean service architecture.
• Practical experience integrating LLM APIs (OpenAI, Gemini, or similar) and building AI-ready backend systems.
• Experience with vector databases and RAG-style retrieval architectures.
• Strong relational database skills including schema design and migrations.
• End-to-end CI/CD ownership from build to deployment.
• Self-starting, go-getter mindset with ownership of problems until solved.
• Bonus: experience with multi-agent orchestration frameworks (Semantic Kernel, LangChain, or similar).

Responsibilities

• Design and scale async REST/WebSocket APIs in Python (FastAPI or similar).
• Implement multi-agent workflows to route work among specialized LLM agents.
• Integrate multiple LLM providers behind a provider-agnostic layer for A/B testing and cost-aware routing.
• Build and maintain RAG pipelines against vector stores (pgvector, Chroma, etc.).
• Design schemas and evolve data models (SQLAlchemy/SQLModel) with migrations.
• Instrument services with structured logs and distributed tracing; monitor cost and latency.
• Own end-to-end CI/CD, linting, typing, testing, packaging, and deployment.
• Set guardrails for generated code, provenance, licensing checks, and data prompts handling.
• Move ideas from concept to production with strong ownership over architecture.
