**Expert NVIDIA Isaac Sim Engineer — Warehouse Vision Simulation & Agentic AI Development**

We’re Zimark, developing computer-vision products that track pallet movements and inventory locations in warehouses.

We’re looking for a senior, hands-on NVIDIA Isaac Sim specialist to build a configurable simulation environment, generate realistic operational scenarios, and help us test and validate our existing product.

**You should bring substantial experience delivering simulation projects for computer vision, robotics, or industrial applications, together with demonstrated ability to accelerate development using AI coding agents.**

Our objective is to keep product development moving when access to physical warehouse test sites is limited.

Our Forklift Vision product has two iterations:

- **Current:** a forklift-mounted camera identifies pallets and reads rack-location barcodes to associate pallets with their destinations.
- **Next:** our fork camera detects pallet pickup and placement, while an external Slamcore localization device supplies forklift location. Our software combines these inputs with relevant height information to determine pallet locations.

The forklifts are human-operated. The simulation needs to reproduce realistic handling and camera observations so we can evaluate our product’s behavior.

**The work includes:**

1. **Build a configurable warehouse environment.** Model forklifts, moving forks, pallets, racks, markers/barcodes and cameras. Start with reusable warehouse assets and accurately represent the geometry that affects our product.

2. **Create realistic scenarios and variations.** Simulate complete pickup, transport and placement sequences, including imperfect approaches, pauses, reversing, aborted pickups, temporary set-downs and repeated handling. Vary camera mounting, rack geometry, marker placement, lighting, occlusion and movement.

3. **Connect simulation to our actual processing pipeline.** Deliver simulated camera footage to our existing NVIDIA Jetson/DeepStream stack, with appropriate video formats, frame rates and timing. Help validate the resulting events through to our backoffice audit log.

4. **Build automated evaluation.** Record what actually happened in the simulation and compare it with our product’s output. Identify wrong pallet/location associations, missed or duplicate events, and timing errors. Keep the planned transfer manifest separate from executed ground truth.

5. **Support the localization-based iteration.** Generate synchronized location, heading and height inputs, including controlled delays, errors and tracking interruptions. Assess integration options for the closed Slamcore device; direct synthetic-camera input is a feasibility question to investigate.

6. **Use agentic AI development effectively.** Apply AI coding agents to accelerate scene creation, scenario authoring, experiment automation and debugging. Provide programmatic controls that make the environment easy to extend and operate.

7. **Validate and hand over the environment.** Compare relevant simulated behavior with available real footage or physical observations. Deliver source files, configuration, documentation and a practical walkthrough so our engineers can independently add and run scenarios.

**You should have:**

- Proven hands-on delivery of substantial NVIDIA Isaac Sim projects.
- Strong Python, Omniverse/OpenUSD and scenario-automation skills, including Isaac Sim APIs and Replicator or equivalent workflows.
- Practical experience with camera simulation, calibration, optics, lighting, occlusion and image degradation.
- Experience connecting simulated sensor outputs to external perception or computer-vision systems.
- Sound judgment about the level of visual and physical fidelity required for a particular test.
- Demonstrated use of AI coding agents while retaining responsibility for architecture, correctness and maintainability.
- Experience creating repeatable experiments, ground-truth logging and validation reports.

Warehouse/logistics simulation, barcode or fiducial-marker testing, NVIDIA Jetson, DeepStream and GStreamer experience are particularly relevant.

**We expect to begin with a tightly scoped paid pilot.** This should demonstrate one warehouse section, representative pallet-handling scenarios, video integration with our processing stack, and an automatic comparison between simulated movements and product events. Please propose the first milestone and its acceptance criteria.

Success means a useful engineering environment that helps us discover, reproduce and resolve product problems.

**Please include the following in your application:**

1. Your most relevant Isaac Sim project: what you personally built, how it was used, and a demo, portfolio item or technical walkthrough you can share.
2. Your approach to connecting a simulated camera to an existing Jetson/DeepStream pipeline.
3. How you would generate imperfect pallet transfers and establish reliable ground truth.
4. A concrete example of using AI coding agents to accelerate a simulation or comparable engineering project, including how you verified their work.
5. Your proposed pilot scope, estimated effort, availability, rate and the largest technical uncertainty you would investigate first.

We value clear technical reasoning, evidence of delivered work and the ability to take ownership from initial design through validation and handover.

Hey! I'm currently developing a game and I'm looking for someone to create a 3D character model based on the reference images I've provided.
I'd like the character to be built using a modular armor system. Essentially, I want a complete base character (undersuit), with each armor piece modeled as a separate object rather than being permanently merged into the main mesh.
This would include the helmet, chest armor, shoulder pads, gauntlets, waist armor, leg armor, and skates. Each piece should be independently editable and removable, but everything should fit together seamlessly when assembled.
I also have an existing character model that's already fully rigged and animated. I'd like to reuse its skeleton, rig, and animations with this new model rather than creating everything from scratch.
Because of this, I'd like the new character to maintain relatively the same scale, proportions, and joint positions as the existing model to make transferring the rig and animations as straightforward as possible.
I can provide both the existing rigged model and the reference images for the new design.

We are seeking to conduct a steady-state electro-thermal (Joule heating) simulation for our electrical panel operating continuously at rated current, 320 Amps (voltage can be negligible).
Our primary objective would be to evaluate a thermal rise across the current path against the requirement standard. Specifically, we would like to detect any high-resistance hotspots caused by undersized bus plates or conductors with lower cross-sections or inadequate connection points.

Physical Mechanism:
Model resistive (Joule) heating caused by current density and geometry constraints (e.g., bus plate sizing).

Output Needed:
Hotspot location mapping, thermal margins, for conductor sizing.
We would also use the data to verify temperature rise along the current path stays below standard maximum limits.
Our goal would be to receive a steady-state thermal map of our current path to determine hotspots as well as to properly size the busbars/connections before physical testing.

We’re Asbion Technologies, a French deeptech startup developing smart indoor and outdoor air quality monitoring devices.

We’re looking for an experienced PCB engineer to review and improve our existing designs, optimize power consumption, explore LiFePO4 battery integration, and prepare our boards for manufacturing with JLCPCB.

- Create correct Python reference solutions
- Develop hidden tests using independently verified expected results
- Include representative materials, edge cases, limiting behavior, phase or transport regimes, and numerically challenging conditions
- Establish justified numerical tolerances and ensure tests accept valid alternative implementations where appropriate
- Independently work through the materials model before reviewing submitted solutions
- Review existing problem specifications, Python reference solutions, hidden tests, and expected results
- Check governing equations, material parameters, units, boundary and initial conditions, constitutive relationships, modeling assumptions, physical plausibility, valid material regimes, stability, convergence, and test coverage
- Determine whether identified issues originate from the problem statement, materials model, solution code, test code, expected result, or evaluation setup
- Document required corrections and rerun corrected solutions and tests before recommending approval

Candidates should have advanced expertise in at least one of the following:
- Semiconductor Materials
- Molecular Modeling

Required Qualifications

- Experience with scientific computing, numerical modeling, or research-level problem-solving
- Ability to translate materials models into correct Python solutions
- Ability to write and debug tests and independently verify expected results
- Ability to critically review scientific coding problems and identify defects in their materials models, solutions, tests, or expected results
- Strong attention to detail and ability to work independently

Preferred Qualifications
- Proficiency with NumPy, SciPy, and relevant materials-modeling or simulation libraries
- Experience with semiconductor modeling, molecular dynamics, atomistic simulation, electronic materials, transport, phase behavior, or computational characterization
- Experience reviewing materials-modeling code, simulation software, scientific datasets, or numerical research workflows
- Experience with AI evaluation, benchmarking, or research coding
- Familiarity with SciCode or similar scientific AI benchmarks; prior experience with a specific benchmark is not required

Selected candidates will be invited to complete a Coderbyte assessment. Candidates who successfully pass the assessment and are approved to proceed will be paid for completing it.

I’m looking for a hands-on mechanical engineer who can dive straight into our food production line and measurably raise production speed. Your core mandate will be process optimization: studying our existing mechanical setup, spotting bottlenecks, and implementing practical changes that let each machine—and the line as a whole—run faster without compromising product quality or safety.

You’ll spend most of your time on the plant floor, gathering data, testing tweaks, and collaborating with operators and maintenance techs. Expect to work with common food-industry hardware (augers, conveyors, form-fill-seal, rotary fillers) as well as the usual toolset for continuous-improvement work—Lean techniques, Six Sigma methods, time-motion studies, and whatever CAD or simulation software you prefer for quick mechanical trials.

To be a strong fit you should point to solid, real-world experience boosting production speed in a manufacturing environment, ideally food or beverage. Share a brief snapshot of the challenges you faced, the mechanical or procedural changes you introduced, and the quantified throughput gains you achieved. That first-hand evidence of impact will weigh far more than a formal proposal at this stage.

Once on board, I’ll walk you through our line layout, existing KPIs, and any regulatory constraints, then hand over the schematics and historical downtime reports so you can set your baseline. From there we’ll agree on improvement targets, a practical timeline, and the resources you’ll need to hit them.

If you’ve unlocked faster cycle times before and are ready to do it again, I’d like to hear from you.
