Job description

Imagine a piloted air taxi that takes off vertically, then quietly carries you and your fellow passengers over the congested city streets below, enabling you to spend more time with the people and places that matter most. At Joby, we've been working to make that dream a reality since 2009 and we're now in the final stages of certifying our aircraft with the FAA. With plans to launch our aircraft in the US and Dubai, we're now scaling manufacturing and preparing for the launch of our commercial service.


Join the Air Taxi Systems team at Joby Aviation as a Software Engineer Intern, where you will directly contribute to building the software that brings quiet, emissions-free flight to the world. In this role, you will assist in developing features across our full technology stack, including backend services, data pipelines, and implementing AI-driven features. You will collaborate closely with product managers, designers, and operations teams to deliver scalable software solutions from ideation to release.


Assist in the development and implementation of features across various parts of the full-stack system, including backend services and internal tools.

Collaborate with cross-functional teams (Product, Design, Flight Ops) to contribute to defining requirements and delivering mobile solutions.

Assist in designing and implementing data flows for seamless app functionality.

Contribute to client/server interactions and occasionally assist with backend APIs.

Contribute to the implementation and integration of AI/ML models into operational software and data pipelines.

Participate in team software processes such as requirement and test plan generation, design doc creation, code reviews and deployments.


Currently pursuing a BS/MS in Computer Science or a related technical field

Basic knowledge of a common modern language (e.g., Python, Go, Java).

Familiarity with foundational concepts in data structures, algorithms, and software engineering.

Familiarity with system design concepts, including client/server interactions.


Experience with a backend language (e.g., Java, Go, Python).

Previous experience in aviation, transportation logistics, or regulated industries.

Experience in high-growth, startup-like environments.

Basic exposure to or coursework in machine learning, data science, or AI applications.


Relocation Assistance: This position does not offer relocation assistance. Candidates must live in the immediate area or relocate at their own expense.
The pay range for undergraduate interns, which includes freshman to senior level students, is $22-$31/hr.
