Spanish Speaking Engineer Intern Jobs in California

Seasonal Internship • San Francisco

Dedalus Labs is an AI research neolab building infrastructure for AI agents.

We are looking for an exceptional Design Engineer Intern who wants to build the interface for the platform that will power the AI agents of the future.

This is not a traditional summer-only internship. We accept applications on a rolling, year-round basis and typically run four internship seasons each year. Each internship lasts approximately three months and is full-time for the duration.

The program is designed for unusually talented, high-slope builders who may not yet be ready for a full-time role but have already demonstrated exceptional ability for their stage. Strong interns may be considered for full-time opportunities.

• Prototype new interactions using modern browser and rendering technologies.

• Contribute production-quality work rather than disposable intern projects.

• Fluency with AI coding tools.

• A public GitHub showing how you think and build.

• Clear evidence of personal ownership over the work you present.

• The ability to explain your decisions, tradeoffs, failed approaches, and hardest technical problems.

• Experience with Canvas, shaders, GLSL, or WebGPU.

You know what good looks like—and your work demonstrates it.

A beautiful portfolio is not enough on its own. We care about the quality of your implementation, the reasoning behind your decisions, the details others overlook, and whether you can turn taste into working software.

• Applications are accepted throughout the year.

• We typically run four internship seasons annually.

• Each season lasts approximately three months.

• The internship is paid and full-time.

• Start dates are coordinated based on candidate and team availability.

• Interns work on substantive projects with real ownership.

• Exceptional performance may lead to consideration for a full-time position, but conversion is not guaranteed.
  

• Full-time for approximately three months.

• In person, five days per week, in San Francisco.

• Relocation support may be available.

• Visa support may be available based on individual eligibility and timing.

• This is not a remote internship.
  

We care more about exceptional work, learning velocity, ownership, and taste than formal credentials.
