About this role
About Gradera — Digital Twin & Physical AI Platform
At Gradera, we are building a next-generation Digital Twin and Physical AI platform that enables enterprises to model, simulate, and optimize complex real-world systems. Our work brings together strategy, architecture, data, simulation, and experience design to power decision-making across large-scale operational environments such as manufacturing, logistics, and supply chain networks.
This platform-led initiative applies AI-native execution, advanced simulation, and governed orchestration to help organizations test scenarios, predict outcomes, and continuously improve performance. We operate with an enterprise-first mindset prioritizing reliability, transparency, and measurable business impact as we build intelligent systems that scale beyond a single industry or use case.
Lead Simulation Engineer
Overview
We are seeking a hands-on, visionary Lead Simulation Engineer to drive the technical direction, architecture, and delivery of our simulation platform for digital twin solutions. This is a foundational leadership role responsible for building the simulation engine that powers real-time scenario planning, what-if analysis, and operational optimization across enterprise digital twins.
You will lead a team of simulation engineers, architect the simulation platform using industry standards (OpenUSD, FMI/FMU), and bridge the gap between physics-based modeling and real-time operational decision-making. We value candidates with strong simulation fundamentals — whether from game engines (Unity, Unreal) or scientific computing backgrounds.
Our simulation platform stack includes:
Scene Description & Composition
- OpenUSD (Universal Scene Description) for hierarchical scene composition and asset management
- Scene graph architecture, layering, and variant sets
- Asset pipelines and schema design
Simulation Standards & Co-Simulation
- FMI/FMU (Functional Mock-up Interface) for model exchange and co-simulation
- Multi-domain system modeling and integration
- Discrete Event Simulation (DES) (SimPy) and continuous simulation
Physics & Optimization
- Physics engines (PhysX, Bullet) for dynamics and kinematics
- OR-Tools for optimization and constraint solving
- Multi-physics modeling (mechanical, thermal, fluid where applicable)
Development
- Python and C++ for simulation development
- Real-time simulation loops, time-stepping, and state management
- Performance optimization and scalability
Key Responsibilities
- Define and own the simulation platform architecture for scalability, extensibility, and performance
- Define and own the simulation strategy data strategy and architecture
- Lead adoption of OpenUSD for scene composition, asset management, and simulation state
- Architect FMI/FMU-compliant components for interoperability and co-simulation
- Design simulation patterns for real-time and batch what-if analysis
- Lead development of discrete event and physics-based simulation models
- Build optimization algorithms for scheduling and resource allocation
- Design co-simulation frameworks integrating multiple domain models
- Optimize simulation performance and build validation frameworks
- Establish engineering standards, code quality guidelines, and architectural patterns
- Provide team leadership: mentorship, code reviews, hiring support, and skills development
Preferred Qualifications
- 10+ years of experience in simulation engineering, game engine development, or scientific computing, with 4+ years in technical leadership roles
- Master’s or PhD in Computer Science, Physics, Mechanical Engineering, Aerospace, Robotics, or related field
- Track record of architecting and delivering production-grade simulation platforms
- Experience building simulation systems that integrate with enterprise data and ML pipelines
Highly Desirable
- Experience building simulations for digital twin platforms
- Background in operations research or logistics optimization
- Experience with real-time simulation for operational decision support
- Contributions to OpenUSD, FMI standard, or open-source simulation projects
- Experience with USD for Unity or USD for Unreal plugins
- Familiarity with visualization pipelines (Three.js, WebGL, or native rendering)
- Publications or patents in simulation, physics modeling, or game engine architecture
- Exposure to industrial domains such as Manufacturing, Logistics, or Transportation is a plus.

About Gradera
For decades, the technology services industry has been built on people and projects.
But in an age of intelligent systems and adaptive learning, that model has reached its limit.
At Gradera, we’re defining the next evolution of enterprise transformation — Software-Orchestrated Services™ (SoS™) — where software governs how work flows across humans, digital workers, and systems to deliver measurable, governed outcomes at scale.
Our model unites advisory, platforms, and solution suites into one orchestrated system of intelligence — continuously learning, evolving, and compounding value across the enterprise.
Through Software-Orchestrated Services™, human expertise is amplified, not replaced. Digital workers and intelligent systems operate through governance, feedback, and explainability to deliver outcomes with trust and precision. Transformation no longer ends; it evolves.
From strategy to scale, Gradera turns enterprise operations into orchestrated, self-improving systems.
Our frameworks — Neural IQ™, NexusFlow™, PhiSphere™, and Value360™ — bring together governance, orchestration, and measurable ROI to help organizations accelerate outcomes and sustain continuous innovation.
Founded by the leadership behind PK Global, Gradera carries decades of enterprise modernization experience — now focused on replacing project-based transformation with a governed, software-orchestrated model of continuous enterprise evolution.
The result is an enterprise that thinks for itself — governed, adaptive, and built to last.
Gradera — defining the era of Software-Orchestrated Services™.
