Principal Software Engineer, Full Stack

About the Role

We are hiring on behalf of an innovative technology company transforming the industrialized construction sector through advanced design automation and cloud-native platforms. The company develops intelligent digital solutions that enable engineers and designers to automate complex building design workflows, visualize structural systems in real time, and optimize design processes through scalable cloud infrastructure.

They are looking for a Principal Software Engineer, Full Stack, to lead the architecture and development of high-performance systems spanning backend services, cloud infrastructure, and advanced 3D visualization interfaces.

Role Overview

As a Principal Software Engineer, you will architect and build scalable, high-performance systems across both backend and frontend layers. You will play a critical role in designing cloud-based algorithms, integrating REST APIs, and building immersive 3D visualization experiences using technologies such as React, Node.js, and Three.js.

This role also involves providing strong technical leadership, mentoring engineers, and driving engineering best practices while ensuring systems are optimized for performance, scalability, and security.

Key Responsibilities

• Lead the design and implementation of scalable cloud-based architectures and distributed systems.

• Develop algorithms that leverage cloud resources and integrate them with backend services and frontend applications.

• Architect and build full stack applications spanning backend services (Java, Node.js, database modeling) and frontend interfaces (React, Three.js, 3D visualization layers).

• Ensure efficient and secure data flow between frontend and backend components.

• Design and integrate cloud-native systems using Google Cloud Platform services including compute, storage, and databases.

• Provide technical mentorship and leadership to engineering teams through code reviews, architectural guidance, and knowledge sharing.

• Define and drive the technical vision and engineering roadmap for complex systems and product features.

• Collaborate closely with product managers, designers, and other engineering teams to translate requirements into scalable technical solutions.

• Design and maintain secure, scalable REST APIs that enable seamless communication across systems.

• Continuously evaluate new technologies, tools, and frameworks to improve system architecture, performance, and development efficiency.

Requirements

• 10 to 12 years of professional software engineering experience with strong expertise in full stack development.

• Deep experience with Java for backend development and Node.js for scalable server-side applications.

• Strong experience designing, building, and integrating REST APIs.

• Extensive frontend development experience using React and modern JavaScript frameworks.

• Proven expertise with Three.js for developing interactive 3D visualizations and browser-based 3D environments.

• Strong experience with database modeling and scalable database architectures including relational and NoSQL systems.

• Hands-on experience with cloud platforms, preferably Google Cloud Platform.

• Strong understanding of microservices architecture, serverless computing, containerization, Docker, and Kubernetes.

• Proven experience leading engineering teams and making architectural decisions.

• Strong mentoring ability with experience supporting the growth of junior and mid-level engineers.

• Excellent analytical and problem-solving skills.

• Strong communication skills and ability to collaborate across technical and non-technical teams.
