About the role
- As a Senior Full Stack Software Engineer on the Systems Integrity Group (SIG) initiative, you will build simulation and digital twin validation frameworks that verify manufactured output matches engineering intent.
- You will develop full-stack applications powered by Unreal Engine 5 for 3D visualization, create V&V automation tooling, and build interfaces that give engineering and operations teams data-rich, walkable views of the factory and production systems.
Responsibilities
- Build full-stack web applications that orchestrate simulation frameworks, digital twin validation, and V&V automation workflows for manufacturing verification.
- Develop UE5-based 3D visualization interfaces that ingest real-time data from the Unified Namespace and render data-rich, interactive views of factory operations, manufacturing processes, and production systems.
- Partner with manufacturing engineers and factory operators to understand production workflows and translate them into software requirements.
- Write production-quality code with comprehensive tests, participating in code review and architectural discussions.
- Design and implement tooling that verifies manufactured output matches engineering intent by comparing as-built geometry, assembly sequences, and quality measurements against design specifications.
- Build frontend and backend systems that integrate with simulation frameworks (OMNeT++, SimPy, Gazebo, CARLA) to enable factory co-simulation and "what-if" scenario testing.
- Develop automated V&V pipelines that run integration tests, validation checks, and compliance verification across design, manufacturing, and operations domains.
- Deploy and operate your systems in factory environments, including edge compute clusters and OT networks.
- Architect data pipelines that connect CAD models, PLM data, real-time factory sensors, and simulation results into unified visualization and validation workflows.
- Build responsive web interfaces for V&V dashboards, test management, requirements traceability, and system-level validation reporting.
Requirements
- 6+ years of experience in a software engineering role building production systems, ideally in a fast-paced environment.
- Deep expertise in full-stack web development, with demonstrated mastery of both frontend and backend systems.
- Strong technical fluency in modern software architectures, APIs, distributed systems, CI/CD, and cloud or edge infrastructure.
- Proficiency with web-based technologies including JavaScript/TypeScript, React, Next.js, Node.js, and modern web frameworks.
- Experience with real-time 3D engines (Unreal Engine, Unity) or advanced 3D visualization frameworks (Three.js, Babylon.js, WebGL).
- Experience building systems that must operate reliably under real-world operational constraints (high availability, low latency, or constrained environments).
- Strong understanding of 3D graphics, rendering pipelines, and data visualization for complex geometric or spatial data.
- Excellent written and verbal communication skills, with the ability to collaborate across engineering, manufacturing, and operations teams.
- Degree in Computer Science, Information Systems, Engineering, or related technical field, or equivalent practical experience.
- U.S. Person status is required as this position needs to access export controlled data.
Preferred qualifications
- Experience in manufacturing, industrial, or OT-adjacent domains (MES, SCADA, PLC integration, factory automation, IoT).
- Hands-on experience with Unreal Engine 5 (or Unity) for industrial visualization, digital twin applications, or non-gaming applications such as training, simulation, or operations visualization.
- Experience building verification and validation (V&V) systems, test automation frameworks, or quality management software for manufacturing, aerospace, or defense.
- Background in computational geometry, CAD/CAM systems, or visualizing and comparing 3D geometric data (STEP, IGES, OpenCASCADE).
- Experience with simulation frameworks (OMNeT++, Simulink, SimPy, Gazebo, CARLA) and integrating simulation results into visualization or reporting systems.
- Familiarity with frontier AI tooling, AI coding assistants, and AI-enabled software development workflows.
- Experience in hyper-growth startup-like environments, with demonstrated success balancing speed, ambiguity, and long-term system health.
- Familiarity with enterprise systems such as ERP, MES, WMS, PLM, or requirements management tools (Jama, DOORS, Polarion).
