  • Define scalable system designs and establish engineering best practices across the organization.

  • Partner closely with Product and Research teams to translate ideas into production-ready features.

  • Break down complex initiatives into clear technical specifications, implementation plans, and delivery milestones.

  • Mentor engineers and researchers through architecture reviews, code reviews, technical documentation, and pair programming.

  • Improve the reliability, scalability, observability, and performance of our platforms and services.

  • Contribute hands-on to critical parts of the codebase with clean, maintainable, and well-tested code.

  • Drive continuous improvements in developer experience, infrastructure, and deployment workflows.

  • Help foster a strong engineering culture focused on quality, ownership, and collaboration.

What Were Looking for

  • BS/MS in Computer Science, Engineering, or a related technical field.

  • 10+ years of experience building and scaling complex software systems.

  • Strong experience designing distributed systems and service-oriented architectures.

  • Fluency in Python, TypeScript, and SQL.

  • Experience designing and implementing gRPC and Protobuf-based APIs.

  • Experience working with cloud infrastructure on Google Cloud Platform.

  • Strong knowledge of data modeling, performance optimization, and scalable system design.

  • Familiarity with machine learning including LLMs.

  • Experience building Frontends with React.JS.

  • Excellent communication and collaboration skills across technical and non-technical teams.

Bonus Points

  • Experience managing infrastructure as code (Terraform, Pulumi, etc.).

  • Experience working with CAD software.

  • Background in computer graphics, simulation, or physics-based systems.

  • Experience building or working with Domain-Specific Languages (DSLs).

  • Experience deploying or integrating machine learning systems into production environments.

  • Familiarity with Kubernetes-based production environments.

Our Tech Stack

  • Google Cloud, AWS

  • Python, TypeScript

  • Protobuf, gRPC

  • Next.JS, React.JS

  • GitHub Actions
