Staff Machine Learning Engineer

The opportunity

We're seeking a versatile, self-driven Staff Machine Learning Engineer to raise the bar on reliability, scalability, performance, and maintainability of our AI authoring products. You'll drive operational excellence via DevOps best practices, including CI/CD automation, Kubernetes management, infrastructure-as-code, agentic troubleshooting, and robust disaster recovery strategies.

You'll establish cross-team standards for infrastructure and deployments, build a trustworthy A/B testing framework, manage software releases with client-server compatibility in mind, and drive observability across system health and business metrics. The systems you build will span high-level architecture down to hands-on implementation, powering asset generation, LLM inference, and the ML-driven tools that bring AI-assisted game creation to life.

What you'll be doing

• Partner closely with product, design, and other engineering teams to influence the product roadmap.
• Contribute to technical strategy and architectural decisions for Unity AI and backend platforms, balancing short-term delivery with long-term product health.
• Design and implement sustainable, scalable solutions for Unity AI products, pushing the boundaries of the Unity Editor with cutting-edge AI agent technologies.
• Improve the reliability, performance, observability, security, and cost-efficiency of our backend systems, and support investigations into issues like performance regressions and network latency through strong observability and monitoring.
• Run technical spikes with developers to address application infrastructure needs on Microsoft Azure and Google Cloud.
• Build and mature the infrastructure and processes for promoting application code from development to production, writing high-quality, maintainable infrastructure-as-code and Helm deployments, and defining best practices for Terraform Cloud, Helm, and Kubernetes.

What we're looking for

• Experience building and shipping complex, user-facing software products at scale
• Experience delivering and supporting cloud backend services using Terraform, Kubernetes, Helm, and CI/CD pipelines (e.g., Argo, GitHub Actions)
• Hands-on experience with Microsoft Azure or Google Cloud Platform
• Proven track record in observability, including monitoring, logging, alerting, and debugging tools such as Grafana to ensure system reliability and performance
• Strong grasp of software delivery best practices and network security, paired with a quality-first mindset
• Ability to translate business and user needs into technical solutions
• Strong communication and interpersonal skills, with a proven ability to align stakeholders across disciplines and organizations

You might also have

• Exposure to ML infrastructure or LLM inference deployment
• Backend service development experience, including API design
• Familiarity with networking, caching, real-time data pipelines, and relational databases such as PostgreSQL
• Familiarity with languages such as C#/.NET, Python, or Go
• Familiarity with Unity or similar 3D engines
