Senior Software Engineer II, Web Development

About DatologyAIAt DatologyAI, we believe that the quality of training data directly impacts the performance of AI models. Our innovative data curation suite is designed to optimize vast amounts of data, effectively reducing training time and costs, while enhancing model accuracy. With our cutting-edge technology, we enable models to achieve performance levels comparable to those trained on significantly larger datasets, all without escalating costs. Our recent successes in text models and image-text models reflect our commitment to innovation in machine learning.Backed by $57.5 million in funding from industry leaders such as Felicis Ventures, Radical Ventures, and Microsoft, our team consists of pioneers in data research and engineering. Our mission is to simplify how organizations train their models, making data curation accessible to all.This position is based in Redwood City, CA, where we foster a collaborative in-office culture four days a week.

Location: Redwood City, CA (Hybrid — 3 days/week in office)Our MissionAt Quilt, we are dedicated to transitioning humanity away from fossil fuel heating. An astounding 20% of the U.S. global warming emissions originate from homes, surpassing emissions from cars. The primary contributor to these emissions is the burning of fossil fuels for heating. To combat climate change, over 80 million homes in the U.S. must shift from combustion-based heating to efficient electric heat pumps in the coming decades.We believe that achieving this transition requires exceptional products that are easy to purchase and adopt. Currently, most heat pumps lack intuitive design, underutilize software, and present challenges during adoption. We are developing a next-generation home heating and cooling system that is not only aesthetically pleasing but also optimized by AI, outperforming existing solutions by a factor of ten.The ChallengeWhile AI agents can generate code at speeds 100 times faster than human developers, our primary bottleneck lies in code verification. At Quilt, we create software that operates on physical hardware within homes. A software bug could mean a family is left without heat. Our codebase encompasses embedded C++ for custom devices, cloud infrastructure, and mobile applications. Currently, much of our verification process relies on manual testing methods, such as physically visiting a test bench to execute tests.Our goal is to build a robust development factory that streamlines code verification.We are seeking a talented Software Engineer to lead our developer infrastructure initiatives. This includes developing simulators, test harnesses, CI/CD pipelines, and verification systems that empower our engineering team (and our AI agents) to deploy features quickly and confidently. Your contributions will be pivotal in enhancing the efficiency and reliability of our software development lifecycle.

About DatologyAIAt DatologyAI, we revolutionize the training of models by addressing the inefficiencies in data usage. Our innovative data curation suite optimally organizes and enhances petabytes of data, ensuring that your training processes are not only faster but also more efficient and cost-effective. Imagine achieving training speeds that are 7-40 times faster while enhancing model performance to levels that feel as if you’ve utilized over 10 times more raw data. Our approach enables smaller models with fewer than half the parameters to outperform their larger counterparts, significantly reducing deployment costs. Explore our latest insights on text models and image-text models.Backed by a total of $57.5M through Seed and Series A funding, our investors include industry leaders such as Felicis Ventures, Radical Ventures, Amplify Partners, Microsoft, and Amazon, along with AI pioneers like Geoff Hinton and Yann LeCun. Our team is at the forefront of research in data optimization, combining expertise in both data science and engineering to simplify data curation for anyone aspiring to train their own models.This position is based in Redwood City, CA, where we embrace a collaborative in-office culture four days a week.

About DatologyAIAt DatologyAI, we believe that the quality of training data is vital for the performance of AI models. Our innovative data curation suite is designed to automatically optimize petabytes of data, ensuring that your models are trained on the most relevant and effective datasets. By utilizing our curated data, users can experience training times that are 7-40 times faster and enhance model performance as if they had trained on more than 10 times the amount of raw data, all while reducing deployment costs significantly.With $57.5 million raised across two funding rounds, our esteemed investors include Felicis Ventures, Radical Ventures, Amplify Partners, Microsoft, and AI pioneers such as Geoff Hinton, Yann LeCun, and Jeff Dean. Our expert team is dedicated to simplifying the complex task of data curation, empowering anyone to train their models effectively on their own data.This position is located in Redwood City, CA, and we work in-office four days a week.

About DatologyAIAt DatologyAI, we understand that models are only as good as the data they are trained on. A significant portion of training compute is often wasted on data that is redundant, irrelevant, or even detrimental, leading to subpar models that incur higher training and deployment costs. Our innovative data curation suite automates the curation and optimization of petabytes of data, ensuring that your models receive the best training data possible.Training on our curated data can lead to an astonishing reduction in training time and costs, making it possible to achieve 7-40x faster training depending on the specific use case. Moreover, it can enhance model performance as if you had utilized over 10x more raw data without escalating training costs. Our approach facilitates smaller models with fewer than half the parameters to outperform larger counterparts while using significantly less compute during inference, ultimately lowering deployment costs.
