Senior Software Engineer

About the role

Carbon operates at the crossroads of hardware, software, and materials science to deliver production-grade 3D printing for commercial customers. You will join a small, collaborative engineering group building the web applications and backend systems that power a global network of printers. The work spans front-end interfaces, cloud infrastructure, and API design, all aimed at keeping the platform fast and reliable as it grows.

Key facts

What you'll do

• Design and deliver customer-facing web applications that connect with core platform services including Fleet Management, Auth, and internal APIs
• Build REST and gRPC interfaces that expose platform capabilities to other teams, with attention to clean contracts and versioning
• Own front-end and cloud integration work using Google Cloud Platform and scalable database systems to bridge web and edge devices
• Develop complex, data-intensive React interfaces that function as control systems, not simple dashboards
• Lead features from initial design through production release, making architectural choices and selecting appropriate technologies
• Step into unfamiliar parts of the stack when problems arise, learning quickly rather than waiting for a specialist
• Work with product managers to turn customer needs into software designs and support junior engineers through code review and pairing

Requirements

• Bachelor's degree in Computer Science, Software Engineering, or related field, or equivalent hands-on experience
• 6+ years of professional software engineering experience
• Strong React and modern front-end abilities, including component architecture, state management, and performance tuning
• Track record building and shipping web applications that integrate with backend services via REST or gRPC APIs, authentication, and real-time data
• Experience designing production APIs that external applications or clients consume
• History of scaling web applications in production, whether for performance, data volume, or user growth
• Working knowledge of at least one backend language such as Go, Python, Java, C++, or TypeScript/Node, with ability to read and contribute backend code
• Familiarity with cloud platforms (GCP preferred, AWS or Azure acceptable) and modern database architectures
• Solid communication, debugging, and problem-solving abilities
• Willingness to work outside your primary stack when needed
