How often are new jobs added?

New internships are added continuously throughout the day. We monitor company career pages and hiring tools in real time, so most roles appear on InternshipsHQ shortly after they’re posted.

Why can I only view a limited number per day on the free plan?

The free plan is designed to let you explore the platform and see how fresh the listings are. Limits help us prioritize serious applicants and keep the signal high. Pro removes these limits and gives you full access.

What sources do you pull internships from?

We source internships directly from company career pages, startup hiring platforms, and applicant tracking systems like Greenhouse, Lever, Ashby, Workable, and others. This helps us surface roles earlier and avoid repost-heavy job boards.

Are these internships legitimate?

Yes. We actively filter out expired, duplicate, misleading, and low-quality listings. Each role is checked for legitimacy and posting freshness so you’re not wasting time on dead or fake opportunities.

Can I filter by location, experience level, remote, or salary?

Yes. You can filter internships by role, location, experience level, remote or hybrid status, and pay when available. Pro users get access to more advanced and saved filters.

Why are early alerts so important?

For internships, timing matters more than volume. Most callbacks happen when roles are still new and applicant pools are small. Early alerts help you apply before listings get flooded.

Do you show salary or pay information?

When companies include pay information, we display it clearly. Not all internships list salary upfront, but we prioritize transparency whenever the data is available.

Is InternshipsHQ suitable for senior or experienced roles?

InternshipsHQ is primarily built for internships, entry-level, and early-career roles. If you’re looking for senior or leadership positions, you may find limited results here.

About The Company

Astranis builds low-cost satellites for high orbits. Our first product, MicroGEO, offers the world’s lowest-cost satellite broadband. Operating in geostationary orbit, each MicroGEO satellite can provide dedicated satellites to small and medium-sized countries, Fortune 1000 companies, and other commercial customers. Astranis has built a $1 billion backlog for 12+ MicroGEO satellites launching over the next two years. Astranis also offers services across orbits and use cases. With contracts in place with Space Force, NASA, and other government partners, Astranis is working across MEO and GEO to support government science, PNT, and communications missions. Astranis has raised $750 million from top global investors and employs a team of over 400 engineers and builders, headquartered at Historic Pier 70 in San Francisco, California.

About the Role

Astranis builds advanced satellites for high orbits, expanding humanity’s reach into the solar system. Today, Astranis satellites provide dedicated, secure networks to highly-sophisticated customers across the globe— large enterprises, sovereign governments, and the US military. With five satellites on orbit and many more set to launch soon, the company is servicing a backlog of more than $1 billion of commercial contracts.

Astranis is the preferred satellite communications partner for buyers with stringent requirements for uptime, data security, network visibility, and customization. Astranis has raised over $750 million from some of the world’s best investors, from Andreessen Horowitz to Blackrock and Fidelity, and employs a team of 450 engineers and entrepreneurs. Astranis designs, builds, and operates its satellites out of its 153,000 sq. ft. headquarters in Northern California, USA.

Internships at Astranis typically last for twelve weeks, and are hourly roles designed for students who are currently enrolled at a four-year university.

If you have already graduated from a four-year university, please apply to be an Associate Engineer.

As our Radiation Effects Intern, you will be supporting the modeling, analysis, and rigorous electrical testing of actual spacecraft hardware within the space radiation environment. You will have a direct impact on our space vehicles by characterizing electrical component degradation and executing hardware testing at various laboratories across the U.S.

Role:

Evaluate and electrically test fault-tolerant electrical systems operating in a radiation environment
Assist in creating electrical test plans, developing test fixtures, and documenting test activities and results. Practice efficient issue diagnosis and draft clear documentation for review by the team
Support radiation testing campaigns to up-screen components for TID and SEE, focusing on electrical parametric characterization before, during, and after exposure
Work in a cross-discipline manner across teams to inform their decisions with regards to radiation considerations
Support test development and early-stage activities, which include breadboarding electrical circuits, automated test setup verification, and basic cable harness fabrication

Requirements:

Currently pursuing a B.S. in Electrical Engineering, Computer Engineering, or a related engineering field
A passion for hardware development, including working in a fast-paced environment and hands-on electrical testing and troubleshooting
Strong proficiency with essential electronics lab equipment, including the standard use of oscilloscopes, multimeters, power supplies, and source meter units
Experience with Altium Designer (or other PCB design software) for schematic capture and board layout
Demonstrated ability to personally design, build, and rigorously test electrical hardware from scratch
US Citizenship or Green Card
Don't meet them all? Not a problem. Please apply even if you do not meet all these criteria

Bonus:

Familiarity with the space radiation environment and effects on semiconductor devices
Experience with SPICE-based simulators (LTSpice, PSPICE, ADS, etc.) to simulate circuit behavior and faults
Comfortable with soldering, rework, and building specialized test harnesses
Familiarity with fundamental electronics concepts and components (integrated circuits, PCBAs, sensors) and how to benchmark their performance
Experience with radiation transport software (FastRAD, Novice, MCNPX, etc.)

The base pay for this position is $29.00 per hour.
