What does a prototype engineer intern do?

A Prototype Engineer Intern assists in designing, building, and testing early versions of products or components. They work closely with engineering teams to turn concepts into physical models, often using tools like 3D printers, CNC machines, and hand tools. Their role may involve troubleshooting, documenting results, and suggesting improvements based on testing. This internship provides hands-on experience in the product development process and helps interns develop practical engineering skills.

What types of projects and responsibilities can a prototype engineer intern expect during their internship?

As a Prototype Engineer Intern, you can expect to work on hands-on projects that may include designing, building, and testing prototypes for new products or features. You'll likely collaborate closely with engineers, designers, and sometimes manufacturing teams to bring concepts to life quickly. Typical responsibilities include CAD modeling, assembling physical prototypes, running experiments, and documenting results. This role often requires adaptability and problem-solving, as you'll need to iterate designs based on feedback and test outcomes. It's a great opportunity to gain experience with rapid prototyping tools and processes while working in a collaborative, innovative environment.

What are the key skills and qualifications needed to thrive as a prototype engineer intern, and why are they important?

To thrive as a Prototype Engineer Intern, you need a solid background in engineering fundamentals, hands-on fabrication skills, and experience with prototyping processes, typically supported by coursework in mechanical or electrical engineering. Familiarity with CAD software (such as SolidWorks or AutoCAD), 3D printing technology, and basic laboratory or workshop tools is often required. Strong problem-solving abilities, attention to detail, and effective communication help interns excel in collaborative and fast-paced development environments. These skills are crucial for efficiently transforming design concepts into functional prototypes that support innovation and product development.

What is the difference between Prototype Engineer Intern vs Mechanical Engineering Intern?

AspectPrototype Engineer InternMechanical Engineering Intern
Required CredentialsEnrolled in Mechanical, Electrical, or related engineering programsEnrolled in Mechanical Engineering or related programs
Work EnvironmentHands-on prototyping, product development labs, manufacturing settingsDesign, analysis, testing in labs or office settings
Industry UsageProduct design, hardware development, R&D teamsDesign, analysis, manufacturing, and testing teams

Prototype Engineer Interns focus on creating and testing physical prototypes, often working closely with hardware and manufacturing teams. Mechanical Engineering Interns typically engage in design, analysis, and testing of mechanical systems. While both roles require engineering knowledge and may overlap in industry settings, Prototype Engineer Interns are more hands-on with prototyping processes, whereas Mechanical Engineering Interns may have broader design responsibilities.

Job description

Oligo is building a manufacturing-in-the-loop foundation model to automate spacecraft design and production worldwide. Our approach allows customers to focus entirely on their own technology and mission objectives, while we handle everything, from design and manufacturing to launch and operations. Leveraging cutting edge AI-driven generative design and automated manufacturing, our ex-MIT, Harvard, and NASA JPL team work to create the most advanced payload-specific spacecraft at scale in weeks over months.

With world‑class advisors on our board, and fresh funding from top investors like Lux Capital, we’re always on the lookout for exceptional builders, fast learners, and ambitious engineers. Whether your passion lies in spacecraft systems, avionics, ML/AI, or advanced manufacturing, you’ll be collaborating across disciplines on real missions that fly, perform in orbit, and scale internationally.

We pair world-class AI/ML talent with top-tier satellite engineers under one roof to reimagine how space systems are built, starting from first principles. No bureaucracy. No legacy thinking.

If you think you’re a fit, we are extremely excited to meet you.

Spacecraft Engineer Intern (Flight Software)

Are you obsessed with the intersection of code and hardware? Do you want to see your algorithms execute in orbit? Do you thrive on solving complex problems in real-time, high-reliability environments? Join our team as a Spacecraft Engineer Intern and help us build the foundational software for our next generation of spacecraft.

Play a pivotal role in designing, developing, and deploying the critical software that enables our spacecraft to perform their missions. If you're an expert in F-prime, real-time operating systems, and building robust embedded solutions, we want to talk to you!

What You'll Do

As a Spacecraft Engineer Intern, you'll assist in the development, testing, and deployment of our spacecraft’s FSW stack. You will work closely with senior mentors to support:

  • Flight Software: Design and implement flight software components within NASA/JPL’s open-source F-prime framework, focusing on resource-constrained embedded systems.

  • Hardware Interfaces: Write and debug software that talks directly to hardware (sensors, actuators, radios) across protocols like I2C, SPI, UART, and Ethernet.

  • Build Systems: Help maintain and extend our CMake build systems to ensure a smooth development pipeline.

  • Verification & Testing: Develop unit tests and support Hardware-in-the-Loop (HITL) testing to ensure our code survives the harsh environment of space.

  • Documentation: Assist in authoring Interface Control Documents (ICDs) and technical design notes, essential for mission success.

  • Collaborate: Work across disciplines with Avionics and Mission Ops to troubleshoot complex hardware/software interactions.

  • Optional: Researching, prototyping, and integrating Machine Learning (ML) and Artificial Intelligence (AI) algorithms into flight software, optimizing for real-time performance and resource efficiency.

What You'll BringMinimum Qualifications

  • Academic Path: Currently pursuing a Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related STEM field.

  • C++ Proficiency: Strong foundational knowledge of C/C+++ in an embedded context (you should know your way around pointers and memory management).

  • Embedded Curiosity: Prior experience (via internships or high-level student projects) with bare-metal programming or an RTOS .

  • Linux/Git: Comfortable working in an Ubuntu/Linux environment and using Gitfor version control.

  • Problem Solver: A "builder" mindset—you enjoy debugging at the register level as much as you do writing high-level logic.

  • Communication: Ability to explain a technical bug and your proposed fix clearly to the team.

  • Physical: Ability to lift/carry up to 40 lbs (for moving test rigs and hardware benches).

Preferred Skills and Experience

  • F' Familiarity: Previous exposure to the F-prime framework or similar component-based architectures.

  • Networking: Understanding of the OSI model and basic networking protocols.

  • Testing Frameworks: Experience with GTest, PyTest, or CI/CD pipelines.

  • Hardware Tools: Familiarity with oscilloscopes, logic analyzers, or multimeters for debugging.

  • AI/ML: An interest in or exposure to deploying Machine Learning models on edge devices.

Pay Range

  • Salary range: $100,000 - $120,000 / per year.

  • This role is on-site in Hawthorne, CA

Benefits

  • Unlimited PTO

  • Catering provided on-site everyday.
