Job Description
About Rhombus Research:

Rhombus Research is an independent research lab in San Antonio. We build systems that make the behavior of autonomous machines visible and verifiable: coordination and accountability infrastructure for autonomous fleets, spanning swarm robotics, systems security, and data visualization. We treat engineering and design as one discipline. Our work has been presented at IEEE ICRA and will be presented at ITS Texas.

Position Overview:

We are building a public API for Reptile, our browser-based simulation engine for autonomous fleet coordination, so outside researchers can author their own scenarios and run experiments against it. The intern will help design, implement, and test that interface: endpoints and data contracts, a test suite, reference examples, and developer documentation, including validating the API through Reptile's built-in AI scenario builder. You would work directly with the founder on production code from the first week. React and TypeScript required. Remote, with occasional in-person collaboration in San Antonio.

Rhombus Research
Summer 2027 Software Engineering Intern: Simulation API
About us

Rhombus Research is an independent research lab in San Antonio working on coordination and accountability systems for autonomous infrastructure. Our work spans swarm robotics, systems security, and data visualization. Recent work has been previously presented at IEEE ICRA and upcoming at ITS Texas.

We are small enough that you would work directly with the founder on production code from your first week.

The role

We are building a public API for Reptile, our browser-based simulation engine for autonomous fleet coordination. Today Reptile runs scenarios we author ourselves. The goal is an interface that lets outside researchers define their own scenarios, bring their own devices and data, and run experiments against the engine.

You would help design, implement, and test that interface.

Specific work includes

Design an API interface alongside Rhombus Research
Implementing API endpoints and data contracts
Writing the test suite: unit tests, integration tests, and validation against malformed input
Building reference examples that demonstrate how an outside user would use the API
Writing developer documentation, including a getting-started guide and API reference
Identifying gaps and inconsistencies in the design

This is a platform engineering role centered on API design, shared services, and building reliable developer tooling.

What you would get

A portfolio project: A shipped, documented public API with your name in the commit history.
Founder mentorship: Direct collaboration with the founder, including structured weekly one-on-ones and daily communication as needed.
Hands-on domain experience: Practical work across simulation engineering, API design, and developer tooling.
Compensation: Funded through the Students + Startups program. A $6,000 stipend for the 10-week summer term, with housing support and onboarding handled by the program.

What we are looking for
Required

Proficiency in React and TypeScript
Comfort with Git and collaborative development
Ability to read an existing codebase and work within its conventions
Clear written communication, since documentation is part of the job

Helpful but not required

Three.js or react-three-fiber
Experience working with LLM APIs
Experience writing tests, any framework
Interest in autonomous vehicles, swarm systems, or infrastructure

Logistics

10 weeks, 40 hours per week.

Remote. Occasional in-person collaboration in San Antonio.

We prioritize core engineering fundamentals over specific toolsets or domain experience. If you are a strong programmer, we encourage you to apply.
