Unity Developer

About the Role

• nCircle Tech Company is looking for a Unity
• developer with a technical-art mindset to expand the equipment library in
• Skyhook, our construction logistics and BIM visualization application. You will
• take hard-surface construction equipment models, such as cranes, excavators,
• and lifts, and make them move realistically and reliably inside Skyhook. You
• will also teach the system new behaviors by building out our action library.
• This role is hands-on and implementation
• focused. You will work within an established codebase and architecture, adding
• to it rather than reinventing it.

What You'll Do -

• Prepare equipment models for procedural
• animation
• Import FBX models of construction
• equipment and restructure their transform hierarchies in the Unity prefab
• editor to support procedural movement, including Inverse Kinematics.
• Set correct pivots, parenting, and
• joint relationships so booms, jibs, hoists, tracks, and attachments
• articulate cleanly.
• Validate that each prefab behaves
• correctly across its full range of motion.
• Add new equipment to existing systems
• Integrate new models into Skyhook's
• existing equipment framework, following established patterns and
• conventions.
• Extract technical data from
• manufacturer manuals and load charts (for cranes: load capacities, boom
• lengths, radii, configurations, and operating modes) and convert it into
• the dictionary-based data structures referenced at runtime.
• Check data for accuracy, since this
• information drives how users plan lifts and logistics.
• Expand the action library
• Design and code digital,
• robotic-style equipment movements by manipulating transforms through C#.
• Build reusable, composable actions.
• For example, a crawler crane pick-and-place sequence: swing into position,
• lower the hook to the top of the object, raise the hook with the load,
• swing to the destination, and lower the load to its target location.
• Extend the library to a wide variety
• of equipment types, keeping actions modular so they can be chained into
• larger sequences.

Required Qualifications

• Working proficiency in the Unity
• Editor, especially prefabs, transform hierarchies, and the prefab editor.
• Solid foundational C# skills and
• familiarity with the Unity API (MonoBehaviours, transforms, coroutines or
• equivalent, ScriptableObjects, collections and dictionaries).

Experience preparing and importing

• FBX assets, including hierarchy, pivot, and scale cleanup.
• Understanding of how procedural
• animation works, including Inverse Kinematics and transform-driven motion.
• Comfort reading and navigating an
• existing codebase and extending it in line with its conventions.
• Ability to read technical
• documentation and translate tabular or chart-based data into structured,
• accurate code.
• Strong attention to detail and a
• habit of testing your own work.

Preferred Qualifications

Experience with heavy equipment or

• hard-surface mechanical models.
• Familiarity with construction
• equipment, especially cranes, and how to read load charts.

Experience with Unity's Animation

Rigging package or custom IK solutions.

Experience with version control

• (Unity Version Control/Plastic SCM or Git) in a team setting.
• Basic 3D modeling knowledge (Blender,
• 3ds Max, or similar) for minor model fixes.
• Background in construction, AEC, or
• simulation software.

What Success Looks Like

• New equipment models are imported,
• rigged, and functioning correctly in Skyhook with minimal rework.
• Equipment data matches manufacturer
• specifications and behaves correctly at runtime.
• The action library grows with clean, reusable
• movement behaviors that other team members can build on.
