# Ben Fasoli > Staff Software Engineer @ Redwood Materials Location: Bozeman, Montana, United States Profile: https://flows.cv/benfasoli Experienced software engineer with accomplishments as a technical leader and individual contributor. My core experience is designing and building distributed data platforms for event-driven, math-intensive workloads across domains including physical process modeling, financial technology, and IoT control systems. I value proactive problem-solving, individual responsibility, collective growth, and consistent incremental progress. In leadership roles, my goal is to cultivate outcome-focused, high-impact product teams and support individuals' development through structured mentoring relationships. ## Work Experience ### Staff Software Engineer @ Redwood Materials Jan 2024 – Present Sustainable battery materials for scalable energy storage and electric vehicles. ### Software Engineer: Applied Science (Contract) @ Breakthrough Energy Jan 2024 – Jan 2024 | Kirkland, WA Platform engineering for contrail modeling to reduce aviation's climate impact. https://sites.research.google/gr/contrails/ ### Head of Engineering @ Pngme Jan 2023 – Jan 2024 | San Francisco, California, United States Pngme enables millions of users without traditional credit scores to access financial services in emerging markets. Led Pngme's engineering and data science teams including hiring, managing, and mentoring a diverse team of remote engineers distributed across multiple continents. Set technical direction and shaped engineering best practices, culture, and processes. ### Staff Software Engineer @ Pngme Jan 2022 – Jan 2023 | San Francisco, California, United States Worked across Pngme's Product Engineering, Data Platform, and Data Science teams to evolve interdependent data-intensive systems. Commercialized a gradient boosting credit risk regression model directly resulting in multiple enterprise partnerships. Developed repeatable strategies for feature selection, hyperparameter optimization, performance evaluation, calibration, and drift detection. Authored technical model explainability documentation that enabled customers to navigate regulatory compliance in multiple countries. Designed core identity and access control services for compliance with enterprise bank cybersecurity and regulatory requirements including SOC2 and GDPR. Implemented usage-based API pricing and drove adoption among B2B2C customers. ### Senior Software Engineer: Applied Science @ Pngme Jan 2021 – Jan 2022 | San Francisco, California, United States Technical lead of Pngme's Data Platform team responsible for financial data services, APIs, and machine learning models predicting credit risk for millions of users in Sub-Saharan Africa. Scaled infrastructure serving financial data and modeling products to process >5k ingress events/second from millions of users. Developed backprocessing systems to support evolution of data transformation logic while enforcing data consistency in downstream databases. Events can be replayed from a log-based message queue or reinjected from targeted queries against a data warehouse. Rearchitected core domain services to establish common integration and communication conventions supporting repeatable extension by individual contributors. Improved developer efficacy by standardizing CI/CD, static code analysis, and testing using local infrastructure components across new and legacy services. ### Research Associate: Atmospheric Sciences @ University of Utah Jan 2017 – Jan 2021 | Salt Lake City, Utah, United States Research scientist focused on greenhouse gas and air quality research using integrated measurement, analysis, and modeling systems. Lead contributor to the Stochastic Time-Inverted Lagrangian Transport (STILT) particle dispersion model which is used to locate and quantify greenhouse gas emission sources. Designed a Kubernetes control plane for scaling compute-intensive atmospheric simulations using fault-tolerant distributed services and preemptible compute instances to optimize cost efficiency. Led development of automated air quality measurement systems for Google Street View vehicles and Salt Lake City's light rail trains. Collaborated with Google and the Environmental Defence Fund to develop new methods to evaluate sub-neighborhood-scale pollution exposure. Built order submission and inventory management web app for WMO-traceable reference air tanks. Contributed to methods, analysis, data visualizations, and technical writing for publications spanning multiple research domains. ### Chief Technology Officer @ Scribe Engineering Jan 2017 – Jan 2020 | Salt Lake City, UT Scribe uses IoT technologies to modernize environmental measurements with high-accuracy data acquisition systems. Technical co-founder responsible for fundraising, driving hardware and software engineering objectives, and collaborating with partners to iterate on product capabilities. Designed fleet management SaaS product that enabled customers to manage networks of connected devices reporting high-frequency environmental sensor data. ### Software Engineer: Applied Science (Contract) @ Aclima, Inc. Jan 2018 – Jan 2019 | San Francisco, California, United States ### Graduate Research Assistant: Atmospheric Sciences @ University of Utah Jan 2013 – Jan 2016 | Salt Lake City, UT Developed data pipelines for automated environmental data capture, quality control, and measurement calibration. Scaled ingress services and infrastructure to process 10M events/day. Designed and deployed measurement control systems that integrate environmental sensor arrays, automate valve systems, and synchronize data with remote servers. Built internal web app to monitor system health diagnostics across multiple networks of environmental measurement systems. Designed abstractions for consuming legacy atmospheric transport models via high-level interfaces (Python, R, CLI), which enabled parallel processing workflows to cost-efficiently utilize SLURM-based HPC systems. ## Education ### Master of Science - MS in Atmospheric Sciences and Meteorology University of Utah ### Bachelor of Science - BS in Atmospheric Sciences and Meteorology University of Utah ## Contact & Social - LinkedIn: https://linkedin.com/in/benfasoli - Website: https://benfasoli.com --- Source: https://flows.cv/benfasoli JSON Resume: https://flows.cv/benfasoli/resume.json Last updated: 2026-03-22
