Slingshot AI

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 Member of Technical Staff focused on Software Engineering, you will ship product end to end: designing, building and launching the features that make Ash an even more engaging and effective product.

As a core member of a small but highly skilled team, we expect you to act as an owner and care passionately about delivering value to our users and ultimately to make people's lives better. We want builders who care deeply about the quality of their work and want to ship things that make a real difference in people's lives.

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 and Rust for low level media streaming. We use gRPC and GCP (Kubernetes, Cloud Run) as our primary cloud provider. You do not need to be an expert in all of these tools, but we want you to come with a learning mindset and to be ready to get hands dirty with whatever tool the job might require.

• 6+ years of software engineering experience, with a track record of shipping consumer products used at meaningful scale in high growth, high quality environments.
• Strong product instincts and real opinions about UX, performance and craft. You notice the latency that makes the app feel slow even when the metrics look fine, and you fix it.
• Driven by creating a world class product with a world class team, want to own what you build, and you're happy tearing down experiments and features as we learn.
• Comfortable building across the full stack, a keen learner who picks up new languages, technology stacks and concepts quickly.
• Experience working in a fast paced environment, owning end to end features and experiments that ship in days.

• Experience working on apps with realtime or voice features.
• Experience working on service oriented systems in production.
• Experience building and shipping Flutter apps in production.
• Experience working with ML codebases (we don't need you to be an ML Engineer, but having an interest in AI helps!).

• Collaborate within a cross functional team spanning engineering, machine learning and product to quickly design, build and launch new features across the stack.
• Work comfortably across all parts of our stack, which includes the app (Dart/Flutter), core backend (Kotlin), internal tooling (Next.js/TypeScript), and ML scripts for evaluation, data processing and model training (Python).
• Elevate user experience by continually refining app reliability, performance and polish.
• Rapidly investigate, diagnose and resolve bugs to ensure product stability.
• Take initiative to independently prototype new features based on customer feedback and your own product intuitions.

What we offer:

• A chance to join a passionate tight knit team working on something to change the world
• Competitive compensation (top of personal market)
• Travel between our NYC / London offices
• Usual startup perks like free lunch and coffee in office plus generous learning budget
• We cover your personal therapy
