Our team is a diverse group spanning machine learning, product, engineering, and clinical expertise. We are a passionate, fast-iterating team that dreams big and cares deeply about our users.

About the Role

This is an exciting opportunity to join a passionate team leveraging cutting-edge AI to improve global mental health access. As a Member of Technical Staff focused on Production Engineering, you will be instrumental in building and scaling the platform that powers Ash. You will work across voice and AI stacks, internal services, and data systems, focusing on enhancing observability, deployment, and platform tooling for reliable scaling.

As a core member of a small, highly skilled team, you will act as an owner, driven by a passion for delivering value and improving users' lives. We are seeking builders who are committed to the quality of their work and want to ship impactful products.

Our tech stack includes Dart/Flutter for the app, Kotlin for backend services, Python for ML, Next.js/TypeScript for internal tooling, and Rust for media streaming. We utilize gRPC and GCP (Kubernetes, Cloud Run). While expertise in all areas is not required, a strong learning mindset and a willingness to work with various tools are essential.

Key Responsibilities

• Strong systems intuition and well-developed opinions on latency, reliability, and cost.
• A drive to build a world-class product with a world-class team, with a desire to own your work and adapt systems as needed.
• Comfortable building across the full stack and a keen ability to learn new languages, technologies, and concepts quickly.
• Experience working in a fast-paced environment, taking systems from prototype to scaled production rapidly.

Nice to Have

• Experience with production AI inference or model serving systems.
• Experience with real-time systems such as voice, live communications, or streaming.
