Job description

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service deliveryassociated with traditional satellite and terrestrial IoT systems.

We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.

We are looking for a Senior Electromechanical Engineer to own electrical, optical and sensing harness/interconnect products for a space-based antenna application. This is a hands‑on role for someone who enjoys developing unique solutions to unique problems - from preliminary system design and component selection to qualification, integration & flight.

What you'll do:

• Own the design and selection of the spacecraft’s wiring harness — electrical wiring, optical fiber, connectors, and interconnects.
• Own antenna specific sensors and their integration, routing, and signal interfaces.
• Define harness and connector requirements and drive component selection and supplier evaluation.
• Take harness, connectors, and fiber through qualification for the flight environment.
• Develop routing, strain‑relief, and integration approaches compatible with a spacecraft structure.
• Create harness drawings, wire lists, and interface documentation.
• Support assembly, integration, and test, and resolve harness‑related anomalies throughout the entire product lifecycle.

Required qualifications:

• Own the design and selection of the spacecraft’s wiring harness — electrical wiring, optical fiber, connectors, and interconnects.
• Own antenna specific sensors and their integration, routing, and signal interfaces.
• Define harness and connector requirements and drive component selection and supplier evaluation.
• Take harness, connectors, and fiber through qualification for the flight environment.
• Develop routing, strain‑relief, and integration approaches compatible with a spacecraft structure.
• Create harness drawings, wire lists, and interface documentation.
• Support assembly, integration, and test, and resolve harness‑related anomalies throughout the entire product lifecycle.

Preferred qualifications:

• Optical fiber / fiber‑optic harness experience.
• Sensors and instrumentation integration.
• Space or flight environmental qualification (thermal‑vacuum, vibration, radiation).
• Experience with space structures.

Location

On‑site in California or Texas. Some travel between sites may be required.

Additional Requirements

This is a fast‑paced, high‑impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.

$140,000 - $190,000 a year

This role is ideal for an engineer who gets excited about impossible parts and has the skills to build whatever it takes to make them work at production volumes.

We are redefining how satellites are designed, manufactured and used—so we’re looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in‑orbit activities. If that’s your experience – then we’ll be immediately wow‑ed.

E‑Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.

Why E‑Space is right for you:

As a member of our team, you will play a crucial role in driving our success. Our team members have a strong sense of dedication and responsibility; this includes a strong commitment to our mission to create an entirely new suite of global capabilities to improve lives, business efficiencies and build a smarter planet. This means that there will be times when extra hours, including nights and weekends, may be needed to meet critical deadlines and mission goals. In return, we offer a dynamic work environment with opportunities for professional growth and development and the chance to make a meaningful impact in a high‑growth industry.

We want you to make the most of your journey at E‑Space. That’s why we support and invest in the physical, emotional and financial well‑being of our team members and their families. Some of what you can expect when working at E‑Space:

• An opportunity to really make a difference
• Sustainability at our core
• Fair and honest workplace
• Innovative thinking is encouraged
• Competitive salaries
• Continuous learning and development
• Health and wellness care options
• Financial solutions for the future
