What is a 4D developer?

A 4D Developer is a software developer who specializes in using the 4D platform, a relational database management system with an integrated programming language. They design, develop, and maintain applications, typically for business process automation, data management, and custom software solutions. Their responsibilities include writing code, debugging, optimizing database performance, and integrating third-party tools. 4D Developers often work with SQL, scripts, and APIs to enhance functionality.

What does a 4D developer do?

A typical day for a 4D Developer often involves designing, developing, and maintaining custom business applications using the 4D development platform. You might spend time writing and debugging code, optimizing existing database structures, and collaborating with project managers and end-users to gather requirements and address technical issues. Team meetings are common to review progress and align on project goals, and you may also coordinate with non-technical departments to ensure software meets organizational needs. Frequent problem-solving and adapting to new technology updates keep the role dynamic and engaging. Being proactive and responsive are key to excelling in this environment.

What are the key skills and qualifications needed to thrive as a 4D developer?

A 4D Developer should have strong programming skills in 4D (formerly 4th Dimension) development environments, a solid grasp of database management, and relevant experience in software engineering. Familiarity with 4D's integrated development tools, experience with client-server architectures, and knowledge of scripting languages such as SQL or JavaScript are highly beneficial. Excellent problem-solving abilities, attention to detail, and effective communication are valued soft skills in this position. These capabilities enable 4D Developers to build robust business applications and collaborate efficiently with technical and non-technical stakeholders.

Job description

The Simulator Team at Waymo builds state-of-the-art simulations of realistic environments for testing, training, and validation of the Waymo Driver. Our team is a diverse, and collaborative group of machine learning (ML) engineers, software engineers, and ML research engineers. We develop industry-leading simulation solutions using advanced generative and reconstructive ML algorithms, to model the real world, encompassing realistic agents, roads, traffic systems, weather, and the full sensor suite (Camera, Lidar, Radar).

To accelerate the fidelity, scalability, controllability, and richness of our simulations, we are pushing the frontiers of 3D world modeling. We leverage state-of-the-art ML technologies trained on large-scale datasets to create dynamic and semantically rich virtual worlds, directly impacting the development and validation of the Waymo Driver.

In this role, you will report to a Senior Staff Engineering Manager.

You will:

  • Lead the design, development and deployment of cutting-edge 4D world models and generative systems for ultra-realistic and controllable sensor and semantics generation for simulation use cases at waymo.
  • Architect and implement scalable and robust ML pipelines for training, evaluating, and deploying large-scale generative models into our simulation infrastructure, including techniques like model distillation and quantization.
  • Build and scale production-ready video generation techniques (e.g., Diffusion, Flow Matching) to create dynamic and interactive simulation environments.
  • Apply Vision Language Models (VLMs) to enhance the semantic understanding and controllability of our world simulation products.
  • Partner with world class research teams across Waymo and Alphabet to leverage State-of-The-Art research in 4D world modeling and generative AI into robust, production-ready solutions.
  • Mentor and provide technical guidance to other engineers on the team.

You have:

  • MS or PhD in Computer Science, Machine Learning, Robotics, or a related field.
  • 5+ years of experience in ML engineering and applied Deep Learning, with a strong portfolio of shipped products or publication record.
  • Proven experience in developing and training large-scale generative models for video generation (e.g., Diffusion models, Flow Matching) or Vision Language Models (VLMs) and their applications.
  • Deep expertise in 3D World Modeling or 3D computer vision.
  • Familiarity with 3D reconstruction and rendering techniques (e.g., 3D Gaussian Splatting).
  • Strong programming skills in Python and experience with ML frameworks such as Jax/Flax, PyTorch or Tensorflow.

We prefer:

  • PhD and a strong track record of delivering impactful ML products in 3D generative models, world models, or video generation..
  • Experience in simulating sensor data (Camera, Lidar, Radar) and/or semantic scenes.
  • Experience with autonomous systems, robotics, or autonomous vehicle simulation.
  • Experience in training and optimizing large scale models on GPU/TPU clusters for efficient serving.
  • Experience in C++ for production systems.
