About The Position

Rocket Lab is seeking a Senior Software Engineer I for its Digital Engineering team, based at the Littleton, Colorado site. The role develops next-generation simulation and modeling tools supporting aerospace systems, including flight and ground software capabilities. The engineer contributes across the software development lifecycle, from requirements definition and design through coding, testing, and deployment, and works with a collaborative team to deliver scalable architectures, intuitive user interfaces, and robust solutions. The technology stack includes .NET, Angular, relational databases, and RESTful APIs. The position involves building mission-level wargaming tools covering space, air, and ground domains, and products for analyzing laser communication constellation networks. Applications use web technologies and must run across Windows and Linux. The engineer applies UI/UX practices, collaborates on requirements and system architecture, participates in design and code reviews, and improves performance and scalability for large simulations and data processing. U.S. citizenship is stated as required due to program requirements.

Requirements

Bachelor's degree in Computer Science, Computer Engineering, or a related technical discipline.
At least 5 years of software development experience, focused on simulation, modeling, or aerospace systems.
Proficiency in C#/.NET and Angular, or a similar frontend framework such as React or Vue.
Experience with TypeScript/JavaScript and building RESTful APIs.
Strong understanding of relational databases such as MySQL, SQL Server, or SQLite.
Solid grasp of object-oriented programming principles and design patterns.
U.S. citizenship is required due to program requirements.
