Internship Fastapi information

What is an internship in FastAPI?

An Internship in FastAPI is a temporary position for students or recent graduates to gain hands-on experience working with FastAPI, a modern Python web framework for building APIs. Interns typically assist in developing, testing, and deploying web applications using FastAPI, often under the guidance of experienced developers. This internship helps participants strengthen their Python programming skills, learn best practices in API development, and understand the workflow of real-world software projects. It also offers networking opportunities and can serve as a stepping stone to a full-time role in backend or web development.

What types of projects can interns expect to work on during a FastAPI internship?

As a FastAPI intern, you will typically work on building and enhancing backend APIs, often as part of a development team focused on creating scalable web services or integrating third-party APIs. Projects may include implementing new endpoints, optimizing performance, writing automated tests, and collaborating with frontend developers to ensure seamless data flow. You'll gain experience with asynchronous programming, modern Python practices, and tools like Docker and Git, while often participating in code reviews and agile sprint meetings. This hands-on exposure is valuable for understanding real-world backend development workflows and best practices.

What are the key skills and qualifications needed to thrive as an internship FastAPI developer, and why are they important?

To thrive as an Internship FastAPI developer, you need a solid understanding of Python programming, RESTful API concepts, and basic web development principles. Familiarity with FastAPI, version control systems like Git, and experience using tools such as Docker or Postman are typically expected. Strong problem-solving abilities, eagerness to learn, and effective communication skills help interns collaborate and quickly adapt to new challenges. These skills and qualities are crucial for efficiently contributing to API development projects and succeeding in a fast-paced learning environment.

Job description

San Francisco, CA · Hybrid · Full-time
Compensation: $150,000–$250,000 + equity

About the Company

Our client is a seed-stage, venture-backed startup building an agentic AI platform for enterprise software delivery. Their product is already in live use across large enterprise implementations, and they are growing a small, high-caliber engineering team.

Founded 2024 · ~15 people · Industry: B2B, Enterprise, AI

The Role

As a Product Engineer, you will own features end to end across the full stack, working on a product embedded in live, high-stakes enterprise implementations. You will talk directly with customers, turn their problems into working software, and own what you ship all the way through deployment and beyond. You take best practices seriously and treat AI tooling as a way to move faster without cutting corners.

What you will be doing

  • Build across the full stack: data pipelines, LLM integrations, agentic workflows, and the customer-facing interfaces users rely on daily.
  • Work directly with customers to translate real friction into shipped product, then own it through deployment.

Tech stack: TypeScript, Python, SQL, cloud infrastructure, LLMs (React frontend, Python/FastAPI backend)

Requirements
  • 0 to 5 years of experience as a full-stack or product engineer.
  • A track record of shipping products or features to real users (strong internships and substantial side projects count for newer grads).
  • Experience at an organization with a high engineering bar, ideally a venture-backed startup.
  • A computer science degree from a strong program, with clear evidence of technical excellence.
  • Full-stack capability, ideally TypeScript/React on the frontend and Python/FastAPI on the backend.
  • Demonstrated ambition and high ownership, shown through ambitious side projects, hackathons, strong companies, or similar signals.
Nice to Haves
  • Experience at companies building B2B or ERP-adjacent products.
  • Experience building LLM-powered features.
  • A portfolio of recent, ambitious side projects.
Why Join
  • Own meaningful work end to end on a product used in large, real-world enterprise deployments.
  • Join a small, high-bar team where the standard is ambition and ownership.
  • Competitive base pay plus above-market equity at an early-stage company.
Details
  • Location: San Francisco, CA
  • Work policy: Hybrid, in-office Monday to Thursday, remote Friday
  • Compensation: $150,000–$250,000 + equity
  • Visa sponsorship: Open to transfers (OPT, H-1B); H-1B and O-1 sponsorship for US-based candidates
  • Employment type: Full-time
