## Job description

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 $1.2 billion from some of the world’s best investors, including Andreessen Horowitz, Baillie Gifford, Blackrock, Fidelity, Franklin Templeton, and Snowpoint, and employs a team of 500 engineers and entrepreneurs. Astranis designs, builds, and operates its satellites out of its 153,000 sq. ft. headquarters in Northern California, USA.

Thermal Intern (Summer 2027)

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

As an Intern, you will have an amazing opportunity to work on hard problems — we pride ourselves on giving everyone at Astranis a chance to do meaningful work on complex projects, no matter their seniority. Many past interns have designed and tested hardware/software that is heading to space on our first satellite, and many of them are now full-time employees at Astranis.

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

## Role

- Work together with the engineering team to design, evaluate, build, and test satellite hardware and/or software.
- Support design trades that successfully balance performance margins, resource use, risk, cost, and schedule.
- Perform thermal analysis to varying degrees of fidelity (simplified to detailed) on a variety of different types of hardware such as propulsion components, batteries, high powered electronics, RF components, mechanisms, and printed circuit boards (PCBs).
- Design, evaluate, procure and test thermal solutions such as heaters, heat pipes, thermal interface materials, and surface coatings.
- Develop processes and procedures for integration and assembly which ensure thermal design intent is met. Collaborate with the integration and test team in the installation of thermal hardware as needed.
- Plan and run thermal vacuum testing and verification at the component and spacecraft level.

## Requirements

- Currently pursuing a B.S. or M.S. in mechanical, aerospace, or equivalent technical degree (e.g. physics or applied math)
- A passion and enthusiasm for hardware development, including working in a fast-paced environment and hands-on design and development
- Demonstrated ability to personally design, build, and test 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

- Experience with CAD
- Experience with analytical software thermal analysis such as ANSYS and Thermal Desktop
- Experience with electronics systems design and packaging
- Experience (projects or previous internships) related to aerospace

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

Base Hourly Pay $29—$29 USD

U.S. Citizenship, Lawful Permanent Residency, or Refugee/Asylee Status Required

## About Astranis

## Company Overview
- **One-liner**: Astranis designs, builds, and operates small, radiation-hardened geostationary (GEO) satellites for dedicated broadband and government missions.
- **Entity Type**: Private (Series E, total funding >$1.2B)
- **Headquarters**: San Francisco, California, United States
- **Founded**: 2015
- **Founders**: John Gedmark (CEO), Ryan McLinko (CTO)

## Core Business
- **Primary industry**: Space Research and Technology – geostationary communications satellites.
- **Target customers**: Telecommunications operators (B2B), U.S. Government (Space Force, NASA), allied nations.
- **Mission statement**: “Connect the world” and “extend humanity’s reach beyond Low Earth Orbit.”

## Products & Services
- **[MicroGEO]**: A small, radiation-hardened GEO satellite that delivers dedicated broadband (up to 8.5 Gbit/s per satellite). Used for commercial connectivity and government missions (communications, PNT, science).
- **[Government Programs]**: Prime contractor for Space Force’s Resilient GPS program; contracts with NASA and other defense partners for high-orbit spacecraft.
- **[Satellite Services]**: End‑to‑end design, manufacture, test, and operation of GEO satellites. Over $1 billion in satellite services sold across 10+ satellites on contract.

## Market Standing
- **Valuation**: Not publicly disclosed.
- **Key Metric**: Total funding raised >$1.2 billion (latest Series E of $450M added in 2025).
- **Notable Investors/Partners**: BlackRock, Venrock, Andreessen Horowitz, Y Combinator (Winter 2016 cohort). Customers include Pacific Dataport (Alaska), Orbits Corp (Philippines), Thaicom (Thailand), Orbith (Argentina), Apco Networks (Mexico), and U.S. Space Force.
- **Growth Signals**:
  - Headcount: 439 employees (+21.4% YoY) as of mid‑2025.
  - 5 satellites currently on orbit; 10+ under contract.
  - Goal to launch 100 satellites by 2030.
  - Selected to design next‑gen Resilient GPS satellites for Space Force.
  - Expanded into government science, PNT, and national security missions.

## Competitive Advantages
- **Only company building small, radiation‑hardened satellites for GEO** – traditional GEO satellites are behemoths costing hundreds of millions; Astranis’s compact design slashes cost and lead time.
- **In‑house manufacturing and testing** at Historic Pier 70 (San Francisco) – full vertical integration from machining to final test.
- **Radiation‑tolerant electronics** that survive the harsh GEO environment without expensive custom radiation‑hardened components.
- **Dedicated satellite networks** – each MicroGEO provides a private, resilient link, unlike shared LEO constellations.

## Strategic Focus
- Scale production to 100+ satellites by 2030, targeting both commercial broadband and major U.S. Government programs of record.
- Expand beyond communications into position, navigation, and timing (PNT), science, and national security missions.
- Strengthen “New Prime” role for defense space contracts.

## Why Work Here
- **Culture**: “Calling, not a career” – mission‑driven team working on the world’s most advanced high‑orbit satellites.
- **Work model**: Fully in‑person, 5 days per week at a historic factory/shipyard turned spaceship factory.
- **Compensation**: Competitive pay, broad equity ownership, and comprehensive health/wealth/well‑being benefits.
- **Impact**: Directly connect millions of people to affordable internet and support U.S. national security from space.
- **Growth**: 131 active job openings across hardware, software, manufacturing, operations, and government programs (as of mid‑2025).
