Senior Python Engineer - Backend & Data (Remote)
About this role
About Bold Business
Bold Business is an AI-first U.S.-based company building automation systems, AI agents, and production software for clients like AT&T, JP Morgan, and Verizon. We ship real systems that deliver impact — not experiments.
The Role
We’re hiring a Senior Python Engineer who can own both backend systems and the data layer behind them. This role sits between backend and data — you will build APIs, design pipelines, and ensure the data powering AI systems is clean and reliable.
You’ll work under a Lead Architect. You are expected to execute independently and own outcomes.
What You’ll Do
- Build and maintain production Python APIs (FastAPI or similar)
- Design and run data pipelines (ETL, ingestion, transformation)
- Own data quality — validation, monitoring, failure handling
- Structure data for RAG systems and AI agents
- Design and manage databases (PostgreSQL + vector DBs)
- Integrate external systems (APIs, webhooks, third-party tools)
- Debug across backend, data pipelines, and AI outputs
Non-Negotiables (Knockout Requirements)
You should not apply if you cannot clearly demonstrate all of the following:
- Strong English communication (written and spoken)
You can clearly explain technical concepts to non-technical stakeholders and operate in a U.S.-based team environment. - You have built and maintained production Python APIs
(not tutorials or small scripts — real systems in use) - You have owned data pipelines end-to-end
(ingestion → transformation → reliability in production) - You are strong in SQL and database design
(schemas, performance, tradeoffs — not just basic queries) - You have worked with real, messy data
(multiple sources, failures, edge cases — not clean datasets)
Required Skills
- Python (4–6 years, production backend + data work)
- FastAPI or similar frameworks
- Strong SQL and database design
- API integrations (REST, webhooks)
- Testing and clean Git workflows
AI / Data Context (Expected Working Level)
- LLM API integration (OpenAI, Anthropic, etc.)
- Understanding of how RAG systems use data
- Prompt structure and output handling
- Exposure to vector databases (pgvector, Pinecone, etc.)
Nice to Have
- LangChain, LangGraph, CrewAI
- Airflow, Prefect, or pipeline orchestration
- AWS / GCP experience
- Docker / CI-CD
- Basic BI / analytics tools
What This Role Is
- A hands-on builder role
- Ownership of backend + data layer
- High accountability, low hand-holding
What This Role Is Not
- Not a pure Data Engineer
- Not an ML research role
- Not a junior position
Final Note
- We will go deep into your past work.
- If you can clearly explain what you built, why you built it that way, and what broke — you’ll do well here.
- If not, this role will be a stretch.
Bold Business — AI-First. Delivery-First.
