Key job responsibilities

‍
As a Guidance, Navigation, and Control software engineer, you will develop real-time, embedded software that flies the satellite; ground-based applications that predict orbital state, monitor for potential collisions, and optimize maneuvers; high fidelity modeling and simulation software; and all sorts of infrastructure needed to develop and operate the system. Because GNC is the heart of the satellite flight system, you will frequently be pulled in to help with a broad spectrum of problems standing in the way of satellite integration and test, manufacturing, and even flight operations.

‍

A day in the life

‍
This is an opportunity to play a significant role in the design of an entirely new satellite system with challenging performance requirements. The large, integrated constellation brings opportunities for advanced capabilities that need investigation and development. Scale also puts emphasis on engineering excellence so our tools and methods, from conceptualization through manufacturing and all phases of test, will be state of the art as will the satellite and supporting infrastructure on the ground. You will split time working well defined SW projects needed by the program on a schedule, prototyping design concepts that may or may not make it to production, participating in component and satellite level testing, and helping with flight operations.

Basic Qualifications

- Experience programming with at least one modern language such as Java, C++, or C# including object-oriented design

Preferred Qualifications

- Experience in at least one of embedded systems and avionics, feedback control systems, or real-time software
- Familiarity with interdisciplinary developments that involve hardware, software, and algorithm co-design and verification
- Expertise in real-time operating systems, embedded Linux with real-time extensions, systems programming, concurrency, and scheduling.
- Expertise building, testing, and verifying real-time or safety-critical systems.
- Experience with sensors, actuators, embedded vehicle electronics/avionics, and/or control systems.
