Software Engineer

Who you are

• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience
• 5+ years of experience writing high-quality production code
• A solid background in algorithms, data structures, and system design
• Experience working with modern machine learning tooling — PyTorch, MLflow, data catalogs, and similar
• Hands-on experience building and operating highly available services in production
• Strong product instincts and a track record of shipping developer-facing tools that people choose to use
• Experience building and maintaining open-source projects
• Experience building and operating machine learning infrastructure in production
• Experience building highly available serving systems
• Experience using Ray

What the job involves

• Anyscale is looking for a Software Engineer to join the ML Developer Experience (MLDevX) team
• MLDevX owns the experience layer of the Anyscale platform: the interfaces through which users and coding agents discover, configure, run, observe, debug, and productionize AI workloads
• Every user journey crosses this layer through the CLI, SDKs, APIs, UI, Workspaces, MCP, or the workflows and integrations built on top of them
• Together, these form the user’s primary interface into Anyscale, turning distributed computing from a systems problem back into a coding problem
• We build the common contracts, tools, control-plane services, and architecture that power these surfaces
• You will work across the stack from developer tooling to cloud infrastructure and the Ray runtime
• Manage long-running operations and make failures across jobs, tasks, actors, nodes, and GPUs easier to diagnose
• The systems you build must scale with the platform, remain predictable through failures, and be intuitive for developers, programmable for applications, and operable by coding agents
• This is a high impact individual-contributor role with end-to-end ownership
• You will work directly with users and field teams to identify high leverage problems, shape the product and technical design, and build and operate the solution
• The scope spans the AI workload loop - data preparation, fine-tuning and post-training, serving, evaluation, and iteration as well as the developer loop: code, submit, monitor, debug, optimize, and re-submit
• We are looking for someone with strong product judgment, a willingness to understand the user base, and the technical depth to build high quality software for everyone from a developer learning Ray for the first time to an AI-native company or enterprise running production workloads at scale
• Build the next generation of developer tooling and MLOps capabilities on Ray, designed for both developers and coding agents
• Develop an agent-first CLI and cohesive SDK, API, and MCP surfaces with self-discovery, structured errors, dry-run support, and consistent behavior across platform resources
• Work across the Anyscale Workspaces stack to improve the path from local code to distributed execution, including environments, dependencies, images, authentication, workload submission, and debugging
• Build cohesive experience, tools and frameworks for the AI development lifecycle, including data preparation, fine-tuning and post-training, evaluation, production serving, dataset management, experiment tracking, and lineage
• Build the path from a trained model to a reliable production endpoint, including model registration, deployment workflows, performance benchmarking, and LLM-specific service metrics
• Surface observability across the CLI, SDK, UI, and agent-facing interfaces so users can diagnose failures across jobs, tasks, actors, nodes, and GPUs
• Design open integrations using durable standards such as OpenAI-compatible APIs and OpenTelemetry, along with stable Jobs and Services interfaces for external orchestrators
• Design and operate the highly available backend services and platform architecture that power these capabilities across serverless and bring-your-own-cloud environments
• Work closely with users and field teams to scope, ship, and iterate on the product, and collaborate with distributed systems and machine learning experts to push the boundaries of AI infrastructure
