Member of Technical Staff

Slingshot AI is the team behind Ash, the first AI designed for mental health. Our mission is to make support more accessible and help people change their lives in the ways they want.

We're building a world-class team by empowering individuals with the autonomy, flexibility, and support they need to do their best work. We dream big, iterate fast, and care deeply. If that sounds like you, we'd love to hear from you.

Our team spans machine learning, product, engineering, conversational design, clinical, growth, and operations, with offices in both New York City and London.

We're a well-funded Series A company, having raised $93M from Andreessen Horowitz, Radical Ventures, Forerunner Ventures, plus top-tier tech investors involved in ElevenLabs, Captions, Shopify, Plaid, Notion, Canva, Twitch, Airtable, and many others.

This is a chance to join a passionate team leveraging cutting-edge AI to improve mental health access globally. As a Senior Product Engineer, you will play a critical role in making Ash an even more engaging and effective product. You will work in a cross functional Product team containing traditional product, design, and software development expertise as well as machine learning/AI specialists. Your work will span the entire stack end-to-end, from developing new features in the app, to behind the scenes automations and integrations to make Ash a more powerful tool.

As a core member of a small but highly skilled team, we expect you to act as an owner and to care passionately about delivering value to our users and ultimately to make people's lives better. We are looking for builders that care about the work being done and want to be part of shaping what Ash is, not just complete what's in a ticket.

Our tech stack uses Dart/Flutter for the app, Kotlin for core backend services, Python for our ML work, Next.js/Typescript for internal tooling, as well as Rust for low level media streaming. We use gRPC and GCP (Kubernetes, Cloud Run) as our primary cloud provider. You're not required to be an expert in all of these tools, but we would like you to come with a learning mindset and to not be afraid of getting your hands dirty with whatever tool the job might require.
