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
- 2+ years of contributing to new and current systems architecture and design (architecture, design patterns, reliability and scaling) experience
- 1+ years of non-internship professional software development experience
- Bachelor's degree in computer science or equivalent
- Experience with full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations
- Experience with algorithms, data structures, data modeling, schema design and test-driven development

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.
- Experience with simulation in various contexts: hardware-in-the-loop, monte-carlo, emulators.
- Experience with operating remotely deployed systems in extreme environments.
- Experience supporting infrastructure and tool development for scientific/engineering users.

About the company

Amazon

Company overview
Amazon runs a wide set of consumer and enterprise businesses, including online retail, Prime Video and other subscription services, advertising, devices, and Amazon Web Services (AWS). Amazon also builds large-scale software and infrastructure for logistics, payments, and cloud computing, and hires across engineering, product, operations, corporate functions, and frontline roles. Amazon’s early-career hiring spans both office-based teams and operational sites, which means “entry-level” can look very different depending on the org.

Locations and presence

Amazon has major corporate hubs in Seattle and Arlington (HQ2) plus large engineering and operations sites across North America, EMEA, and Asia-Pacific. For many corporate roles, Amazon’s stated expectation has shifted to five days per week in-office for office-based employees (with exceptions depending on role and site).

/ 100
Amazon is one of the most accessible early-career employers at scale, with recurring internships and graduate hiring across many disciplines and geographies. Amazon also provides unusually clear public information about interview mechanics and publishes pay ranges on a large share of roles, which supports informed decision-making. The biggest drag on outcomes is the combination of high-performance culture signals and recent corporate job cuts, which adds risk for early-career stability depending on team and org.
