Game Physics Engineer

Unity / Unreal Engine Developer — Real-Time 3D & Physics Systems Location: India (Remote / Hybrid) Experience: 2–4 years
Type: Full-time

About Kloth.me Kloth.me is building the next generation of fit-intelligent fashion technology — helping people understand how clothes fit their bodies before they buy.
We work at the intersection of 3D geometry, real-time simulation, and AI , turning complex physical and visual systems into fast, intuitive product experiences.
This is not a traditional game studio role.
It’s a real-time 3D and physics systems role applied to a real-world problem at global scale.

Founding Team

• Khanaz K A — Founder & CEO
• 14 years in e-commerce; IIM Ahmedabad MBA.
• 8.5 years at Amazon (Prime & Growth); ex-CPO at Simpl.
• Prateek Chugh — Co-founder & CBO
• Former sales & growth leader at OYO, Classplus, and Simpl.
• One of the strongest go-to-market leaders in India.
• Aditya Todi — Co-founder & CTO
• IIIT Hyderabad alumnus; founding engineer across multiple startups.
• A first-principles thinker with deep systems intuition.

The Role We’re hiring a Unity or Unreal Engine developer to help build and integrate real-time 3D simulation and physics-driven systems that visualize how digital objects interact with human bodies.
You’ll work on engine-level systems that involve:
Integrating and extending built-in physics engines
Configuring soft-body / cloth-style simulations
Bridging approximate real-time physics with deterministic outputs
Supporting downstream AI and rendering pipelines
The deeper intelligence and proprietary pipeline details will be shared after joining or under NDA .

What You’ll Work On

• Integrating and configuring physics systems within Unity or Unreal
• (e.g., Chaos Cloth, custom constraints, collision layers, parameter tuning)
• Building real-time 3D simulation pipelines that are stable, repeatable, and performant
• Working with skeletal meshes, attachments, and runtime bindings

~ Extending engine physics behavior via:

• Custom components
• Constraint logic
• Runtime parameter control
• Tooling for inspection and debugging
• Creating deterministic render outputs for internal use and downstream systems
• Developing internal tools to inspect, debug, and iterate on physics-driven behavior
• Collaborating closely with ML, product, and design teams

What We’re Looking For

• 2–4 years experience with Unity (C#) or Unreal Engine (Blueprints / C++)
• Demonstrated experience integrating, tuning, or extending physics engines in production projects

~ Strong understanding of:

• Runtime physics systems
• Collision handling & constraints
• Soft-body / cloth-like simulations
• Camera, lighting, and rendering fundamentals
• Ability to reason about performance vs realism tradeoffs
• Comfort working in ambiguous, first-principles environments

Nice to Have
Experience beyond games (simulation, visualization, XR, tools)
Prior work where physics output needed to be stable, explainable, or inspectable
Exposure to deterministic rendering or data-generation pipelines
Curiosity about applying real-time physics to non-entertainment domains
Why Join Kloth.me
You’ll work on hard, novel systems , not commodity gameplay
Your work sits close to the core product and IP
You’ll have real ownership and autonomy
You’ll collaborate closely with founders and senior engineers
You’ll help define a new category at the intersection of 3D, physics, and AI
If you enjoy building and integrating real-time physics systems — and care about making them usable, debuggable, and production-ready — we’d love to talk.
