• Collaborate closely with designers, artists, and stakeholders to understand project requirements, translate them into technical specifications, and ensure successful project execution
• Create and optimize 3D graphics, shaders, and rendering techniques to achieve high-quality visual output and optimal performance
• Utilize your expertise in React and GraphQL to integrate front-end applications with back-end APIs, databases, and services
• Meet product requirements in a timely manner, while not compromising the operational stability of the overall product
• Implement and maintain code repositories, version control systems, and deployment pipelines to ensure efficient project management and collaboration
• Mentor and provide technical guidance to junior engineers, conducting code reviews and offering constructive feedback to enhance the team's skills and capabilities
• Stay up-to-date with the latest advancements, trends, and best practices in web-based 3D graphics, including Three.js, shaders, and rendering techniques
• Conduct performance optimization and troubleshooting to ensure smooth rendering, efficient resource utilization, and an optimal user experience across various devices and platforms.
• Collaborate with backend engineers to integrate front-end applications with GraphQL APIs, ensuring data consistency, efficient queries, and a seamless user experience
• Actively participate in agile development processes, including sprint planning, daily stand-up meetings, and retrospectives
• Visualize satellite metric data 
• Perform other duties as assigned (to be less than 10% of the responsibilities listed above)
• Build and design React/three.js components 
• Executes all position responsibilities in alignment with Slingshot’s core values, mission, and purpose

Pre-Requisites

• Must be eligible to obtain or maintain US Government Security Clearance

Minimum Requirements

• BA/BS in Computer Science, Computer Engineering, related field, or equivalent experience
• 3+ years experience with Three.js and related libraries/frameworks for creating high-quality and performant 3D experiences on the web, including projects that involved rendering a large number of objects (50K+) in real-time
• Proficient in Typescript  and have experience with front-end web technologies, such as HTML, CSS, and modern JavaScript frameworks (e.g., React)
• Experience implementing interactive 3D web applications using the Three.js library and other related technologies, such as WebGL, WebXR, React-three-fiber, drei, and GLSL
• 5+ years experience in software and application development, with a strong focus on web development 
• Proficiency in React and its ecosystem, including state management with zustand or equivalent (e.g., Redux, MobX) and component-based architecture
• Strong proficiency in web technologies along with their latest standards and features
• Demonstrated experience with version control systems (e.g., Git), code repositories (e.g., GitHub, Bitbucket), and CI/CD deployment pipelines
• Strong communication skills, both verbal and written, with the ability to articulate technical concepts to both technical and non-technical stakeholders
• Possess strong knowledge of 3D graphics principles, including modeling, texturing, lighting, and animation

Preferred Skills

• Experience with plotly or similar graphic framework 
• Space industry or early-stage tech startup experience 
• Designing and implementing multiplayer/collaboration features in web applications
• Practical knowledge of Graphql, Graphql subscriptions or websockets   
• Prior experience working within DOD software factory environments
• Familiarity with backend development using Node.js, Kotlin, or Java
• Experience with AWS Cloud Native Technologies
• Astrodynamics knowledge
