Job Description

Who We Are 

At Bluehost, we believe all small businesses deserve the opportunity to succeed online. Our mission is to give small businesses the confidence to think big. We're the all-in-one platform for small businesses to grow online with powerful simplicity, premium performance, smart tools and human support. 

This role is a part of Bluehost's innovation team, the group building the AI-native backbone of our platform while the rest of the business scales around us. You'll design async, production-grade backend systems that treat AI as a first-class citizen: multi-agent orchestration, retrieval-augmented generation, and provider-agnostic LLM integration, all woven into products millions of small businesses depend on. We want a true go-getter who can take an idea from whiteboard to production without waiting to be told how. 

What You'll Do & How You'll Make Your Mark 

• Design and scale async REST/WebSocket APIs in Python (FastAPI or similar), using dependency injection, type hints, and clean, vertical-slice architecture 

• Implement multi-agent workflows (sequential, concurrent, and handoff patterns) to route work among specialized LLM agents 

• Integrate multiple LLM providers behind a provider-agnostic layer, enabling A/B testing and cost-aware routing rather than hard-coding a single vendor 

• Build and maintain Retrieval-Augmented Generation (RAG) pipelines against vector stores such as pgvector, Chroma, or a managed vector search service 

• Design schemas and evolve data models (SQLAlchemy/SQLModel-style ORM plus migrations) that support both traditional application logic and AI-driven features 

• Instrument services with structured logs, distributed tracing, and cost/latency metrics, holding a real bar for p95 response time under production load 

• Maintain end-to-end CI/CD ownership, lint, type-check, test, package, and deploy, so releases are boring and safe 

• Champion AI across the delivery lifecycle, not just code generation, and set the guardrails the team works inside: how generated code gets reviewed, how provenance and licensing are checked, and what customer data may enter a prompt 

• Move ideas from concept to production fast, with real ownership over architecture and outcomes, not just tickets 

Who You Are & What You'll Need to Succeed 

• 5+ years building production backend systems in Python, with real async I/O experience 

• Hands-on experience designing and scaling REST or async APIs, including dependency injection and clean service architecture 

• Practical experience integrating LLM APIs (OpenAI, Gemini, or similar) and building AI-readiness into backend systems from the ground up 

• Real experience with vector databases and RAG-style retrieval architectures, not just reading about them 

• Strong relational database skills: schema design, query optimization, and migration discipline 

• AI-augmented delivery: you use AI across the delivery lifecycle, not just code generation, and can say which models suit which problems and where you don't use them. You review AI-generated code knowing its failure modes, and you have set the guardrails others work inside — review expectations for generated code, provenance and licensing checks, and clear boundaries for what customer data enters a prompt and what a security or compliance review will ask for. 

• End-to-end CI/CD ownership, from build and test through packaging and deployment 

• A self-starting, go-getter mindset: comfortable with ambiguity, fast iteration, and owning a problem until it's actually solved 

• Bonus: experience with multi-agent orchestration frameworks (Semantic Kernel, LangChain, or similar) and LLM cost/observability tooling 

Why You'll Love Us 

• Work-life balance. Meaningful work, balanced by a culture that respects your time. 
• A culture of belonging. We celebrate what makes each of us different, with 20+ affinity groups connecting employees globally. 
• We care about you. We offer a Meal Voucher or Food Voucher worth R$44.55 per working day. Comprehensive health and dental insurance, with no employee co-pay.
• Well-being program including Gympass, online meditation, and telemedicine.
• Do you have a dog, cat, rabbit, hamster, goat, turtle, or even a mini dragon? We offer access to a pet health insurance partnership.
• Educational platform: pursue undergraduate and graduate degrees, language courses, and much more through 100+ educational institutions at highly affordable rates.
• Life insurance coverage.
• Free website hosting.
• Where can we take you? Mentorship, new challenges, and real career growth. Unfold new possibilities #OTOD!
