About

In an unmarked building somewhere in Silicon Valley, a small team of engineers is working on what could become one of the most transformative technologies in enterprise computing: autonomous infrastructure that manages itself. Sailplane, backed by AI kingmaker Khosla Ventures (OpenAI's first investor) and seed specialist True Ventures, is building a "self-driving cloud" - intelligent agents capable of autonomously managing the largest and most advanced AI infrastructure on the planet. Sailplane is solving one of the most complex challenges in modern computing: autonomous manufacturing and management of massive AI data centers. We are creating intelligent agents that operate rack-scale systems worth millions of dollars. Think Waymo for cloud infrastructure. "We're building million-dollar agents," explains co-founder Sam Ramji, who previously led product at Google Cloud Platform and brought Linux to Microsoft. "These aren't consumer-grade chatbots - they're sophisticated autonomous systems managing rack-scale hardware worth millions per unit." About the Role Sailplane is an early-stage AI infrastructure startup. Expect to wear many hats (building ML platforms, MLOps tools, data/LLM infrastructure). You will bring a startup mindset, eager to take ownership of projects, navigate ambiguity, and move quickly to solve challenging problems in a fast-paced environment. As a Senior ML Engineer, you will lead the build and operations of LLMs in production on-premise for Sailplane. This is a senior individual contributor role focused on hands-on coding, systems thinking, and prototyping. You won't manage a team, but you will mentor and amplify those around you. You should be fluent in models, adept at integrating production infrastructure and observability, and lead performance benchmarking. You’re comfortable working in code and in diverse production environments, and you care deeply about correctness and quality. This hybrid position reports to the CEO and is expected to work from our downtown San Francisco office 2 to 3 days per week. What you will do at Sailplane
Build, deploy, monitor, and operate LLMs in production on-premises in diverse customer environments Implement MLOps best practices (CI/CD pipelines, containerization, continuous monitoring) to ensure reliable performance Benchmark performance and recommend solutions to improve customer deployments including hardware sizing for target throughout (tokens per second, concurrent user sessions) Experiment and iterate on models by tuning parameters and testing new approaches, continuously improving accuracy and effectiveness through rigorous evaluation Document and ensure reproducibility of ML work, track experiments, code, and model versions to foster knowledge sharing and maintain high standards in the team Collaborate cross-functionally with software engineers, customers, and product stakeholders
What you will bring to Sailplane
8+ years of experience in software engineering, preferably in a VC-backed startup environment Experience with Prometheus, Grafana, distributed tracing, or ML-specific monitoring (Weights & Biases, MLflow for production) Hands-on experience deploying models at scale, including familiarity with containerization (Docker, Kubernetes) and cloud platforms (AWS, GCP, or Azure) to build and operate ML systems in production.Proficiency in programming (especially Python) and experience with modern ML frameworks/libraries such as TensorFlow, PyTorch, etc. Deep understanding of machine learning algorithms and the model development lifecycle (data preprocessing, training, parameter tuning, and evaluation) Proven track record of delivering software that creates real value for users Excellent communication skills with an ability to explain complex ML concepts to non-experts, and a collaborative approach to working with cross-functional teams and partners
Benefits and Perks
Comprehensive Health, Dental, and Vision coverage beginning on the first day for employees and their families, paid 100% by Sailplane Equity grant participation Flexible PTO with no accrual or set annual cap, plus 15 paid holidays per year Health and Wellness stipend ($3,000 annually) to help support your personal health goals AI tools stipend ($1,200 annually) to encourage hands-on familiarity with emerging tools #J-18808-Ljbffr
