At Snowflake, we are powering the era of the agentic enterprise. To usher in this new era, we seek AI-native thinkers across every function who are energized by the opportunity to reinvent how they work. You don’t just use tools; you possess an innate curiosity, treating AI as a high-trust collaborator that is core to how you solve problems and accelerate your impact. We look for low-ego individuals who thrive in dynamic and fast-moving environments and move with an experimental mindset — who rapidly test emerging capabilities to discover simpler, more powerful ways to deliver results. At Snowflake, your role isn't just to execute a function, but to help redefine the future of how work gets done. Observe by Snowflake is an AI-powered observability platform built on the Snowflake AI Data Cloud and engineered for scale. We ingest and store logs, metrics, traces, and events on an open, scalable data lakehouse, using open formats like Apache Iceberg, at dramatically lower cost. A dynamic Context Graph and chat-based AI SRE provide rich context and automated workflows so teams can move from detection to root cause of production issue and resolution 10x faster. Leading engineering teams at companies like Capital One, Topgolf, and Dialpad rely on Observe to troubleshoot hundreds of terabytes of telemetry daily while maintaining reliability at enterprise scale. As part of Snowflake, Observe combines startup-style ownership and velocity with the global reach, operational excellence, and ecosystem of one of the world’s leading data platforms. IN THIS ROLE YOU WILL: * Lead the backend architecture and delivery of the Logs product area by owning the full lifecycle from API design through production reliability, with a strong sense of what makes a great end-user experience. * Drive technical direction for log ingestion, storage, querying, and enrichment pipelines capable of handling hundreds of terabytes of telemetry daily. * Build for both humans and AI agents — design APIs and workflows that work equally well for UI users and programmatic access by AI coding agents like Claude Code and Cursor. * Partner deeply with PMs, Frontend, and Design to shape the product roadmap, translate user needs into sound technical designs, and identify backend capabilities that unlock high-value product experiences. * Champion product thinking on the engineering team — bring clarity to trade-offs, flag gaps in requirements, and proactively surface opportunities to simplify or improve the product. * Set the technical bar through code reviews, architecture reviews, and mentorship, establishing patterns that scale across the broader backend organization. * Champion the use of AI-assisted development tools (e.g., GitHub Copilot, Cursor) to maintain high code quality and accelerate delivery. QUALIFICATIONS: * 7+ years of industry experience building and maintaining high-scale backend systems in production. * Strong proficiency in Go, Java, or a comparable systems-oriented language; comfort working across the stack when needed. * Deep experience designing and operating distributed systems — familiarity with streaming pipelines, columnar storage, or log/event processing is a strong plus. * Demonstrated product acumen: you can read a PRD critically, push back on requirements that don't serve users, and propose simpler solutions without sacrificing outcomes. * Track record of leading end-to-end feature delivery in close partnership with cross-functional teams (PM, Design, Frontend). * Strong written and verbal communication — you can explain technical decisions to non-engineers and influence roadmap priorities with data and reasoning. BONUS POINTS: * Experience building observability or log management systems (e.g., Splunk, Datadog, Elastic, Loki, OpenTelemetry). * Experience operating data lakehouses under high performance and high scale. * Experience with query DSLs, CEL, or similar expression evaluation frameworks. * Prior experience in a tech lead or staff engineer capacity on a product-focused team. Every Snowflake employee is expected to follow the company’s confidentiality and security standards for handling sensitive data. Snowflake employees must abide by the company’s data security plan as an essential part of their duties. It is every employee’s duty to keep customer information secure and confidential. Snowflake is growing fast, and we’re scaling our team to help enable and accelerate our growth. We are looking for people who share our values, challenge ordinary thinking, and push the pace of innovation while building a future for themselves and Snowflake. How do you want to make your impact?

THE TEAM The Avatar Team is at the heart of the Roblox experience. The Roblox Avatar defines the identity of every player and is a core pillar of the metaverse. Within this group, the Avatar Heads and Bodies team ensures that these foundational avatar components are high-quality, performant, and reliable at scale. We are looking for a Senior Software Engineer to join our User-Generated Content (UGC) Validation engineering initiatives. This role focuses on advancing our existing automation and validation systems to ensure that the rapidly growing ecosystem of 3D marketplace content meets our platform standards. THE ROLE As a Senior Software Engineer for UGC Validation, you will focus on scaling and evolving our automated systems to validate 3D assets uploaded directly to the Roblox marketplace. Your primary responsibility will be to develop engineering solutions that quantitatively enforce our marketplace policies. Rather than building systems from scratch, you will expand upon our established validation frameworks to detect avatar schema compliance, flag geometry-based exploits, and programmatically measure asset quality. In this role, you will serve as a core practical resource for geometric processing, helping our broader engineering and machine learning initiatives build highly precise automated setup tools. YOU WILL: * Scale and Extend Automated Validation: Maintain, optimize, and expand our existing engineering systems to analyze 3D geometry, avatar schema compliance, rigging structures, and asset metadata. * Enforce Marketplace Policy: Develop and refine quantitative, programmatic metrics to evaluate incoming UGC assets against platform quality standards and security rules before they reach hundreds of millions of users. * Geometric Processing Resource: Serve as a practical engineering resource for geometric processing, collaborating closely with machine learning teams to enhance asset quality pipelines. * Cross-Functional Execution: Work across the avatar stack, collaborating with engineers, product owners, and artists to translate complex marketplace policy requirements into clean, scalable code updates. * Optimize Existing Pipelines: Enhance sophisticated data and validation pipelines capable of handling large-scale 3D assets like meshes and textures with high runtime efficiency. YOU HAVE: * Education: A BS, MS, or PhD in Computer Science or a related technical field, or relevant work experience. * Expert 3D Math Foundation: Exceptional spatial reasoning and a deep mastery of 3D math, specifically linear algebra tailored for game engines and 3D environments. * Geometric Processing Expertise: Strong experience manipulating and analyzing 3D data, including meshes, vertices, and topology. * Schema & Avatar Knowledge: Solid understanding of avatar schema compliance, rigging, skinning weights, and animation principles. * Software Engineering Excellence: Strong programming skills in C++, Luau, Python (or similar production languages) with a proven track record in system optimization, data pipelining, and complex software design. * Nice-to-Haves: * Hands-on experience with runtime game engines. * Foundational knowledge of rendering pipelines. YOU ARE: * A Proven Problem Solver: You enjoy solving ambiguous, complex technical challenges and have a history of delivering production-ready engineering updates. * A Collaborative Teammate: You thrive in cross-functional environments, bridging programmatic geometry constraints with artist and platform needs. * Mission-Driven: You are passionate about building a safe, high-quality, and civil marketplace ecosystem for a global community.
