About the role

Flight Software Engineer

As a Flight Software Engineer at Argo, you will be a member of the team architecting the full software and simulation stack for Argo's refuellable in-space transport vehicles and other space and ground test systems. You’ll develop C/C++ flight applications, simulations, hardware-in-the-loop tests, and interfaces to avionics, propulsion, and GNC systems. You will help drive the overall spacecraft system architecture, execute vehicle design and higher-level performance and communication system trade studies, and implement the spacecraft’s GNC algorithms into software that controls the vehicle systems. You will actively contribute to the full life cycle of software development at Argo, from early architectural decisions and design through to hardware in the loop testing, on-vehicle functionality, and flight operations.

Responsibilities

Write rigorous, high performance code to support Argo’s high-deltaV, refuellable transport spacecraft to make in-space transportation abundant and affordable

Drive rapid execution and iteration efforts that put our spacecraft in orbit quickly

Hands-on prototyping, integration, troubleshooting, and testing of simulations, flight algorithms, and hardware in the loop testing

Implement rapidly developed code to support development and testing of avionics, propulsion, electromechanical, and other spacecraft systems

Negotiate requirements by having a deep understanding of the company and mission objectives and providing alternative solutions

Conduct design reviews, test readiness reviews, and flight readiness reviews with a heavy emphasis on technical excellence

Qualifications

Bachelor's degree in relevant computer science or engineering discipline

Capable of maintaining flexibility in direction under changing circumstances

Track record of delivering novel, excellent technical products

Strong understanding of operating systems, data structures, networking protocols, communication standards, and computer architectures

Understanding of modeling and simulation, and software development skills, particularly in C/C++/Python

Proven system engineering and configuration management skills

Excellent written and verbal communication skills

Engineer II

1+ years of experience designing flight software for spacecraft or similar systems

2+ years of experience designing complex software that operate in novel time-sensitive and/or embedded environments (autonomous vehicles, drones, spacecraft, etc.)

Senior Engineer

3+ years of experience designing flight software for spacecraft or similar systems

6+ years of experience designing complex software that operate in novel time-sensitive and/or embedded environments (autonomous vehicles, drones, spacecraft, etc.)

Preferred Qualifications

Masters degree in computer science, engineering or physics

Experience writing code for real-time operating systems requiring execution at a deterministic rate

Experience with existing spacecraft flight software frameworks such as ROS, NASA cFS, or MAX

Experience in a start-up or fast-paced software development environment

Experience with spacecraft on-orbit operations and troubleshooting

About Argo Space

The rocket gets you to orbit. Argo gets you everywhere else. We design, build, and operate in-space transportation and mobility vehicles, propelled by water, creating the logistics network necessary to open the industrial space age. Today, space still operates on a fragile, expeditionary, mission-based architecture. Every operation is coupled to launch, and every spacecraft is constrained by the propellant it is built with. Argo breaks these constraints. We are creating the affordable, high-throughput logistics network necessary to enable the industrialization of space. To do this, we created a new class of spacecraft with a unique combination of technologies: high-performance dual-mode water propulsion, on-orbit refueling, post-launch payload pickup, and unprecedented deltaV. Argo spacecraft combine with LEO launch to provide the lowest-cost delivery to GEO and Lunar orbit on demand. Beyond delivery, Argo spacecraft provide next-generation in-orbit logistics, sustainment, and mobility within and across every orbit. Our spacecraft family serves every type and size of customer asset, from delivery or repositioning of traditional small or large satellites to transport of massive cargo containers or propellant tanks. We serve commercial operators, defense users, and civil space programs that need freedom of movement and maneuver: the ability to affordably, responsively deploy to any orbit, reposition assets, and operate without the constraints of launch vehicle capacity or satellite propellant. Argo's long-term architecture sources water propellant from Lunar regolith, creating the first in-space commercial resource and untethering space operations from Earth. This is the transition from the traditional launch-centric, mission-based architecture to a multimodal logistics network. Earth’s economy runs on logistics - the same will be true in space. The industrial space age is coming. Argo is building its foundation. Be a part of our mission: argospace.com
