Platform Architect, Bellwether, X

About X, the Moonshot FactoryX is a diverse group of inventors and entrepreneurs who build and launch technologies that aim to improve the lives of millions, even billions, of people. Our goal: 10x impact on the world’s most intractable problems, not just 10% improvement. We approach projects that have the aspiration and riskiness of research with the speed and ambition of a startup.

About the Team Our team – Bellwether – operates at the intersection of machine learning, geospatial data, and pressing issues with enterprise customers, governments, and more. We focus on severe weather manifestations of climate change, such as wildfires, and aim to use a wide range of data and analytics to better understand and predict what these events could mean for communities and businesses across the globe.

We do this through the detection and classification of the features and patterns of the natural and built worlds, the application of cutting-edge machine learning, and the redesign of the full geo-ML workflow. This work extends into development and production-level work as well, as Bellwether also has a number of products that are live with customers. The result: tools and models that allow a range of industries to better leverage earth observation insights.

About the Role We're looking for a Platform Architect to define and lead the end-to-end technical architecture of the Bellwether platform. That's the data, ML, and cloud foundation that turns petabytes of Earth observation data into hazard, risk, and damage insights for enterprise and government customers.

As one of Bellwether's most senior technical leaders, you'll own how the whole system fits together:how we take in and process planetary-scale geospatial datahow we train, evaluate, and serve models, from geospatial foundation models to production agentic systemshow we deliver secure, reliable products and APIs with explainability and observability in the system

This is a hands-on, senior Individual Contributor role. You'll set multi-year technical direction across ML, data, infrastructure, and product engineering at scale, and you'll still prototype, write critical-path code, and review designs yourself. You'll work closely with Bellwether's engineering, product, and business leaders to balance speed with rigor as we grow from early products into an enterprise-grade platform.

How You Will Make a 10x Impact Own the Platform Architecture:
Define and evolve the end-to-end architecture of the Bellwether platform, along with its multi-year technical roadmap. That covers:
Multimodal incl geospatial data management, ingestion and processingML training and servingfoundation-model and agentic integrationscustomer-facing workflows, APIs, data products and platform

Set Technical Strategy & Standards:
Make the high-stakes calls: build vs. buy, core technology choices, tools integration and platform boundaries. Set up the reference architectures, design-review process, and decision records the team builds on, balancing long-term longevity with rapid prototyping.

Architect for Planetary-Scale Data:
Design fast, cost-efficient and scalable pipelines and storage for petabyte-scale Earth observation data (multi-spectral satellite, Tabular, SAR, LiDAR, and weather/reanalysis data), from raw intake to analysis-ready datasets to support both batch and real time decision making on various downstream tasks.

Build the ML & Agentic Platform Foundation:
Work with ML leads to design the MLOps backbone for continual learning, including distributed training, automated evaluation, drift detection, and data lineage. Build the infrastructure for production agentic systems, with built-in observability and explainability.

Deliver Enterprise-Grade Products:
Design secure,…
