Backend Data Engineer – APIs

Backend Engineer (Python / FastAPI)(Internship)(Unpaid)

On-Site (No Remote) | Full-Time | Fremont, CA

Build With Us

We are building
Talentix

, the career mobility platform for healthcare.

Five million plus clinicians in the United States need faster ways to match, get hired, and move forward.

We are the starting point for that journey.

We are not another job board.

Talentix enables career pivots for clinicians by turning skills and history into next-step paths and routing them to hiring teams.

Join us in the room. Whiteboard. Build. Ship.

We need builders who move fast, solve problems, and get things done.

No perfect resume required. If you've shipped backend systems, we want to see them.

What You'll Build

• Design, build, and maintain REST APIs using
  FastAPI

and
Flask

with ORM models, transactions, and tested endpoints.
- Implement core business logic—validation, pagination, filtering, idempotency, and structured error handling.
- Integrate backend APIs with minimal

views to validate features end-to-end.
- Write
unit and integration tests

(pytest, FastAPI TestClient), maintain
CI/CD

pipelines, and review PRs.
- Apply API security fundamentals: object-level authorization, authn/authz, and input hardening.
- Own SQL and
MongoDB

data models, optimize queries, and manage ORM sessions and transactions.
- Deploy and operate services on
AWS

(EC2, RDS, S3, IAM/Lambda) with least-privilege IAM and basic observability.
- Monitor, debug, and document all builds.
