AirOverflow is looking for a motivated and technically curious Backend Developer Intern to join our engineering team and contribute to the systems, APIs, and infrastructure that power our growing suite of cybersecurity products. Behind every platform AirOverflow builds — whether it's a CTF environment, a security training platform, or a client-facing tool — there is a backend that needs to be well-architected, secure, and reliable. In this role, you will get hands-on experience working on real backend systems in a professional engineering environment, writing code that is reviewed, refined, and shipped. Our backend stack is Python-first, and we work with frameworks including Django, FastAPI, and Flask depending on the requirements of the product — meaning you will be exposed to different approaches to backend development and gain a well-rounded understanding of how Python powers production systems. This internship is designed for someone who has gone beyond the basics of Python, has started building things independently, and is ready to take their skills into a collaborative, professional setting for the first time. We are not looking for someone who has all the answers — we are looking for someone who writes clean code, asks good questions, and takes genuine pride in building things that work. If that sounds like you, come build with us.

A Note on Requirements: Our requirements for internship positions are not strict. The job description simply outlines what we would love for you to have — not a checklist you must fully satisfy. If you are curious, driven, and eager to learn, we want to hear from you.

What You'll Do

• Develop and maintain backend APIs and services using Python with Django, FastAPI, or Flask
• Work on database design, queries, and integrations using relational databases such as PostgreSQL or MySQL
• Assist in building and improving core backend features across AirOverflow's platforms and internal tools
• Collaborate with frontend developers to design and deliver well-structured REST APIs
• Write clean, maintainable, and well-documented code following team standards and best practices
• Debug and resolve backend issues across development and staging environments
• Participate in code reviews and incorporate feedback from senior engineers
• Learn and apply backend security best practices relevant to AirOverflow's cybersecurity context

What We're Looking For

• Solid foundational knowledge of Python — you should be comfortable writing scripts, functions, classes, and working with libraries
• Some hands-on experience with at least one Python web framework — Django, FastAPI, or Flask — even through personal projects or coursework
• Basic understanding of how REST APIs work and how they are structured
• Familiarity with relational databases and writing basic SQL queries
• Comfort using Git for version control and working in a collaborative codebase
• Strong problem-solving instincts and the ability to independently work through errors and bugs
• A portfolio, GitHub profile, or any examples of backend or Python work you have built

Nice to Have

• Experience with Django REST Framework (DRF) or Pydantic for API development
• Familiarity with Docker and containerized development environments
• Basic understanding of authentication mechanisms such as JWT or OAuth2
• Exposure to task queues such as Celery or message brokers like Redis
• Awareness of common web security vulnerabilities — SQL injection, broken authentication, insecure APIs
• Any experience with cloud platforms such as AWS, GCP, or Azure
• Prior work on open source projects, hackathons, or freelance backend projects

What We Provide

• Hands-on experience developing backend systems for real, live products in a cybersecurity company
• Mentorship and code reviews from experienced backend and full-stack engineers
• Exposure to Python backend development across multiple frameworks — Django, FastAPI, and Flask
• Internship certificate and letter of recommendation upon successful completion
• Opportunity to transition into a full-time Backend Developer role based on performance
• A strong, verifiable body of professional backend work to anchor your portfolio
• The chance to build in an environment where backend security is taken seriously from day one
