Electrical Engineering Internship

About Ephemeris Net

We are extending the internet to space.

Ephemeris Net is a pre‑seed space networking company on a mission to provide space connectivity for all through collaborative engineering of commercial space networking solutions. We are creating the infrastructure that will enable the space internet beyond bent pipe—starting with foundational networking infrastructure that will define how data moves through space.

We are supported by our parent incubator SOE, preparing to launch our first payload that will demonstrate a space-based router in Q1 2027. While our work will be incremental, we believe that now is the chance to build foundational infrastructure for how the internet will work in space within the next 5 years.

We are looking for engineering interns to work directly on our two core products: optical terminals for space-based laser communications and the networking service that connects satellites into a space network.

By the end of this internship, you will have worked on something that either goes to space (if working on hardware or embedded firmware/software) or pushes forward the technical capability of our internal network and node simulation.

Your specific project will depend on your background and where Ephemeris Net's needs are sharpest when you start. We will match you to a project that is both meaningful to the company and a strong learning opportunity for you.

Upcoming intern projects include:

• Design and implement optical transceiver FPGA firmware
  
  Buildaspacenetwork simulator
  
  Design and fabricate test fixtures or mechanical subsystems for optical terminal prototypes or their test fixtures
  
  Buildhigh speed optoelectroniccommunicationtest equipment
  
  Write embedded flight software

How optical terminals work: from photonics and beam steering to link acquisition and tracking

How space networking differs from terrestrial networking: delay, disruption, orbital dynamics, and protocol design

How to take a technical project from various startstages toend stages:from scoping through implementation to integration with a production system

Howto interactwithprofessionalsas partofa small, focused engineering teamthatships hardware and software for space

Demonstrated ability to build things: personal projects, research, coursework, or prior internships where you wrote code, designed hardware, or ran experiments that produced tangible results

Strong fundamentals in at least one of: embedded systems and FPGA development, software engineering (C, C++, Python, or Rust), optical or mechanical design,electrical engineering,information theory,or networking and simulation

Ability to work on-site in El Segundo, CA or Oakland, CA for a minimum of 3 months, 3 days a week

Must be a US person(15 CFR § 772.1)

Prior experience with FPGA development (Verilog, VHDL, orSystemVerilog)
Familiarity with optical systems, laser communications, or free-space optics

Experience with network simulation tools or protocol design

Exposure to space systems engineering, orbital mechanics, or flight software

Experience with CAD tools (Solid Works, NX) or PCB design (Altium,KiCad)

You will be assigned a mentor who worksonthe product area closest to your project. You will have regular check-ins and direct access to them for technical guidance.

Before you start, we willmeet to understand your strengths and growth goals andcome up witha project for you.

You are expected to scope your project, execute, and present your results to the team at the end of the internship.

Salary: $70,400 annual salary, prorated for length of internship
