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.
Simulation Engineer
Overview
We are seeking skilled Simulation Engineers to join our Simulation & Scenario Enablement team. You will design, develop, and optimize simulation models that power digital twin platforms, enabling real-time scenario planning, what-if analysis, and operational optimization. This is a hands-on role involving physics-based modeling, discrete event simulation, and co-simulation development using industry standards.
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 (SimPy) and continuous simulation
Physics & Optimization
- Physics engines (PhysX, Bullet) for dynamics and kinematics
- OR-Tools for optimization and constraint solving
- Physics-based modeling (dynamics, kinematics, constraints)
Development
- Python and C++ for simulation development
- Real-time simulation loops, time-stepping, and state management
- Performance optimization and scalability
Key Responsibilities
- Design and implement discrete event simulation models using custom engines
- Develop FMU models and integrate them into co-simulation frameworks (FMI)
- Build OpenUSD scene compositions for simulation state and asset management
- Implement physics-based models for dynamics, kinematics, and constraints
- Build optimization algorithms for scheduling and resource allocation
- Create domain-agnostic simulation patterns reusable across use cases
- Write clean, well-tested Python/C++ code and optimize for real-time performance
- Build simulation data pipelines for state management and event processing
- Partner with ML, data, and visualization engineers for end-to-end workflows
- Participate in reviews and document models, algorithms, and assumptions
Preferred Qualifications
- 7+ years of experience in simulation engineering, game engine development, or scientific computing
- Bachelor’s or Master’s in Computer Science, Physics, Mechanical Engineering, Aerospace, Robotics, or related field
- Track record of delivering simulation models in production environments
- Experience working in agile, cross-functional teams
Highly Desirable
- Experience building simulations for digital twin platforms
- Background in operations research or logistics optimization
- Experience with USD for Unity or USD for Unreal plugins
- Familiarity with co-simulation orchestration and multi-domain integration
- Experience with real-time simulation for operational decision support
- Contributions to open-source simulation or game engine projects
- 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™.
