About the Job
Pivotor AI is a conversational career discovery platform. Most systems built to match people to opportunity were designed to read credentials, not careers. That gap is most visible in healthcare, where two people can share the same title and be doing completely different work. We are building a system that reads the work behind the role and finds what is genuinely possible next.
This is an early team. The work you do here will be visible, consequential, and yours. Whatever your function, you will be shaping something genuinely new.
What You'll Do
- Build and maintain FastAPI REST APIs using SQLAlchemy ORM and MVC architecture for internal services and partner integrations
- Implement secure authentication using Firebase Auth (OAuth, secure cookies)
- Develop and productionize proof-of-concept features across backend, data, and AI systems
- Design ETL pipelines with Apache NiFi for scraping, validation, and storage across MongoDB, S3, and LLM endpoints
- Build high-throughput scraping pipelines using BeautifulSoup, Selenium, multiprocessing, and rate-limiting strategies
- Implement NLP pipelines for deduplication, entity matching, and enrichment using spaCy, regex, and LLMs
- Work across AWS infrastructure (EC2, RDS/PostgreSQL, Lambda, S3, IAM, VPC) to deploy and scale services
- Build and maintain CI/CD pipelines with GitHub Actions and production services using NGINX and PM2
- Contribute to LLM + RAG systems, MCP server integrations, and LangGraph agent workflows
- Build internal tools and dashboards using Next.js and Tailwind
- Whiteboard. Iterate. Launch.
Who You Are
You think in systems, not endpoints
You ask why before how
You prototype before you present
You'd rather be in the room than on a thread
What You Bring
0.5 to 1 year of backend engineering experience (projects, internships, or coursework count)
Strong Python backend development experience (FastAPI, Flask, or similar frameworks)
Experience building REST APIs and working with ORMs like SQLAlchemy
Familiarity with SQL and NoSQL databases (PostgreSQL, MongoDB; graph databases a plus)
Experience building data pipelines, scraping systems, or ETL workflows
Exposure to NLP pipelines, LLM APIs, or RAG architectures
Familiarity with cloud infrastructure (AWS) and deployment workflows
Hands-on experience with MCP, Cursor, or Claude for AI-assisted development (mandatory)
A GitHub portfolio that demonstrates how you think and build systems
Requirements
Available immediately and on-site in Fremont
Must accept terms of an unpaid internship with potential for conversion
Why Join
On-site, because whiteboards beat Slack.
This starts unpaid. The 90-day conversion is about equity and full-time.
Our current team includes people from Stanford, UC Berkeley, UCLA, and Carnegie Mellon.
E-Verified employer. Students at UC Berkeley, Santa Clara University, and partner institutions often earn course credit.
