Executive Assistant at Ephemeris Net, Inc – El Segundo, California

About Ephemeris Net

We are extending the internet to space.

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

We are supported by our parent incubator Second Order Effects, institutional VCs, and our network of space advisors. As space use scales and more space native networks come online, we believe that now is the chance to build foundational infrastructure for how the internet will work in space.

The role

We are hiring an Executive Assistant to be the operational backbone of Ephemeris Net. This is a high-trust, high-visibility role that touches nearly every part of the company; people, office, vendors, IT, and executive support.

We want to be upfront about the shape of this role. In the early days, the work will lean heavily toward executive support and day-to-day administration: scheduling, onboarding logistics, processing invoices, owning the office, and covering operations functions in transition from our parent incubator. That is the foundation, and it is the job for the first several months.

From there, the role grows with you. As the company scales, you will have the option to either broaden into general ownership across the Operations function, or go deep into supporting a specific executive - our CEO or our CTO. We will shape the path with you based on your interests and where the company needs the most leverage.

Depending on long term career interests and preferred base office (LAX or OAK), this role will report to the Head of Commercial Growth and Operations, the CEO, or the CTO.
