Find Simulation Software Projects Easily

We are looking for one or more programmers to work on Python-based simulation models and AI automation of those models at sistemaFutura.

At sistemaFutura, we combine simulation modeling and behavioral science to study and improve complex problems. We work on a range of issues, from gender-based violence to climate adaptation and financial inequality; in each case, the concept is the same: we build empirically calibrated, theoretically guided models of a complex problem, which we analyze for opportunities to make a meaningful change.

We have already built a custom simulation engine in Python as part of a deterministic workflow with optional (user-triggered) AI-automation. We are looking for programmers to work both on the engine and the AI-automation. The key parts of the tech stack are: Python, React + Tailwind, LangChain/LangGraph, Weaviate + Temporal.

Very few candidates will have built this type of AI-enabled simulation model before -- that's fine. We are looking for a strong foundation of (A) object-oriented python skills and (B) experience in scientific modeling or complex data analyses. This generally means a mid level to senior software engineer (4-10 years of experience).

We use Claude Code and Cursor, and we'd expect you to as well, whenever useful. However, that isn't a free pass: we'll assess your ability to critically analyze the code these tools develop, critique and design your own architectures, etc.

Please note that it is very important that (a) you're in a time zone or have a work schedule that makes it easy to coordinate with the Western Hemisphere (Central US / Central America), and that (b) you are proficient at speaking English. Since we'll need to train you on some of the aspects of what we do, ease of communication (time and language) are essential.

At this point, we can't offer a full time job, but we hope to build to that over time for one or more excellent candidates.


Finally -- please please don't spam us with messages outside of Upwork. It's really annoying (and, against the terms of use)!

• What is the most complex (length of code, complexity of task) application or application component project you've personally developed?
• What are three design patterns or software patterns you've used?
• How do you approach maintaining and refactoring a large codebase to ensure code quality and scalability?
• Include a link to your GitHub profile and/or website

We are seeking an experienced VFX artist to create high-quality cinematic visual effects for video content and media productions. We are interested in a wide range of digital effects including fire, sparks, smoke, debris, energy beams, electric arcs, light bursts, fog, rain, dust, volumetric lighting, impact effects, shattered surfaces, shockwaves, portal transitions, distortion effects, teleportation visuals, magical auras, holograms, glow effects, and sci-fi power sequences. If you specialize in additional cinematic VFX styles beyond these examples, please include them in your proposal.

All effects should be seamlessly integrated into footage with strong motion tracking, realistic lighting interaction, accurate perspective matching, and polished cinematic color grading. The final result should feel natural within the scene while maintaining a high-end visual style.

We are looking for someone with a strong portfolio demonstrating cinematic VFX work, proven experience in compositing and tracking, and the ability to match environmental realism across different shots. Clear communication, reliability, and attention to detail are highly valued. Please share relevant portfolio examples, software expertise, and your typical turnaround time for similar projects.

Seeking a CLO3D expert to create 2D patterns, POM charts, and 3D simulations for a highly technical offshore sailing glove. The project requires precision and attention to detail to ensure the glove meets performance and durability standards. The ideal candidate will have experience in textile design and simulation software.

We are seeking an experienced electrical engineer to conduct simulations using Proteus for a PWM DC motor controller. The project involves working with components such as the SG3525 IC, MC34063, LM358, IR2117, or similar. The ideal candidate should have expertise in circuit design and simulation, as well as familiarity with PWM control techniques. You will be responsible for creating accurate simulations and troubleshooting any issues that arise during the process. If you have a strong background in electrical engineering and simulation software, we would love to hear from you!

We are looking for a skilled professional to simulate the dynamics of an excavator breaking rocks using NX Motion or SimCenter 3D Motion. The ideal candidate will have a strong background in mechanical engineering and experience with motion simulation software. Your work will help us better understand the performance and efficiency of our excavator designs under different conditions. If you have the expertise to deliver high-quality simulations, please apply with your portfolio and relevant experience.

Job Title:
Windows Desktop UI Developer – Branded Launcher (WPF / Desktop App)

Project Overview:
We are looking for a developer to create a modern, full-screen Windows launcher interface (“UI skin”) for our 9-1-1 Reality training simulator.

This is NOT a simulator build. The simulator already exists. We need to get away from Windows and folder icons - unprofessional and outdated.

We need both Instructor (active links) and Student (non interactive) screen layout (see attachments). We will need to label the three models of simulator and have the ability to name the multiple stations (Instructor 1, Instructor 2, Student 1, Student 2.) We have two models dark and light and want to receive both for testing.

The goal is to replace a basic Windows folder interface with a professional, branded launcher that makes the product feel like a real, polished software system.

What You Will Build:

A full-screen desktop application that:

Launches our existing simulator (.exe)
Opens a Video Tutorials folder
Opens other folders or applications as indicated on the skin
Displays a clean, modern UI with large navigation tiles
Runs in a borderless, full-screen mode (no Windows UI visible)
Core Features Required:

Full-screen launcher (Windows desktop)
Large button/tile interface:
Start Simulator
Video Tutorials
User Manual
9-1-1 Academy
Ai Callers

Ability to launch external applications and folders
Clean, responsive UI with hover states
Fast startup and reliable execution
Optional: subtle animations for polish

Technical Requirements:

Preferred: WPF (C#)
Acceptable: WinForms or Electron (must justify choice)
Must run on Windows desktop environments
Experience launching external processes (Process.Start or equivalent)

Design Expectations:

Must feel like a professional product, not a folder system
Clean, modern UI (not generic templates)
Strong visual hierarchy and spacing
Touch-friendly / large click targets

We will provide branding direction and example visuals.

Deliverables:

Working launcher application (.exe)
Fixes or changes to Chat creation
Source code
Build instructions
Full documentation
User Manual with Troubleshooting

Desired:

Experience with kiosk/full-screen apps
Experience designing or implementing UI animations
Experience with training or simulation software interfaces

Required Qualifications:

Proven experience building desktop applications (Windows)
Strong UI implementation skills (not just backend)
Experience with custom-styled UI (not default Windows controls)
Ability to replicate modern UI designs accurately

To Apply, Please Include:

Examples of desktop applications you’ve built
Screenshots of UI work (important)
Your recommended tech approach (WPF / Electron / other)
Estimated timeline

Important Note: Chat created the image, and chat will evaluate your credentials. We have the hi resolution icons. Fluent in English ONLY

This is a UI/UX polish project, not a complex system build.
We are looking for clean execution, attention to detail, and a professional finish.
