Develop an existing autonomous digital representative project for Mountain Jewels
Mountain Jewels is developing SAM, a photorealistic female digital representative using Unreal Engine and MetaHuman. She will welcome customers into an interactive virtual showroom, hold natural conversations, wear and demonstrate jewelry, provide accurate product guidance, and complete authorized business tasks.
We are seeking a hands-on developer/technical artist who can take ownership across digital character development, animation, and agentic AI integration.
Where the project stands
This is an existing project with visual assets, a showroom, and platform development already underway:
- SAM’s appearance is established: We have an approved character reference and an editable Blender model. The current model is a static bust; full character preparation, rigging, and animation remain to be completed.
- The showroom exists in Unreal Engine: An initial environment has been built, packaged, and uploaded to Vagon for private-preview testing.
- The application foundation exists: Command Center, backend, and Unreal integration work is in place, with an established architecture to inspect and extend.
- The development direction is documented: We have researched character, animation, voice, agent, motion-capture, and streaming tools.
- The next stage is integration and refinement: The complete autonomous SAM experience has not yet been demonstrated end to end.
The successful applicant will assess the existing work, identify what can be retained or improved, and develop it into a convincing, reliable experience. Project materials will be provided through an appropriately scoped handoff.
The work
- Refine SAM’s likeness, skin, eyes, hair, facial/body rig, outfits, and jewelry fitting.
- Create convincing expressions, lip synchronization, gaze, gestures, and body movement.
- Integrate motion capture, voice generation, listening, and interruption handling.
- Develop agent capabilities: reasoning, planning, approved knowledge retrieval, controlled memory, tool use, and task execution.
- Establish permissions, refusal rules, and human escalation. External content and visitor messages must not override company instructions.
- Enable improvement through reviewed knowledge updates and evaluated experience while protecting SAM’s core identity and operating boundaries.
- Connect product information and shopping workflows with Shopify.
- Optimize and test browser streaming, initially using Vagon.
- Maintain source files, documentation, tests, and a repeatable process for introducing products, outfits, animations, and software upgrades.
Experience we are looking for
Strong demonstrated experience across Unreal Engine, MetaHuman, Control Rig, Animation Blueprints, Blueprint/C++, and production AI-agent or API integration.
Relevant supporting tools include Maya, ZBrush, Houdini, Marvelous Designer, Substance 3D, motion-capture retargeting, Live Link, NVIDIA Audio2Face/ACE, and Pixel Streaming.
This role spans several disciplines. Please identify your strongest areas, what you can personally deliver, and where you would require specialist support. We welcome substantial overlapping experience and a credible approach to the complete project.
SAM’s purpose
SAM is Mountain Jewels’ dedicated digital representative. Her identity, knowledge, actions, and customer interactions must reflect the company’s products, values, and policies. She should operate independently within defined boundaries, using persistent context and authorized tools to serve customers and the business.
Engagement
This begins as paid contract work, with the potential to become a full-time position leading SAM’s ongoing development and maintenance. Scope, milestones, compensation, and working arrangements will be agreed before work begins.
To apply
Please send:
- Your portfolio and relevant demonstrations.
- Videos of characters speaking and moving in Unreal, where available.
- Examples of agentic AI, real-time voice, or interactive systems you have built.
- Your personal contribution, technical strengths, and experience taking over existing projects.
- Availability, location/time zone, rates, and interest in a future full-time role.
