AI Engineer

Slingshot AI

We're a team of machine learning engineers training task-specific generative models for psychology. Our goal is to build an AI therapist to help people change their mind and their lives in the ways that they want to. We partner with organizations around the globe and power use cases, including AI-assisted crisis text response, while securing best-in-class datasets to power our models.

Success to us means every human being in need of support having somewhere to go. We're a well-funded, seed-stage startup backed by top-tier tech investors involved in Huggingface, ElevenLabs, Replit, Captions, Shopify, Plaid, Notion, Canva, Twitch, Airtable, and others

We're building a powerful team by empowering our engineers with the autonomy, flexibility, and resources to do their best work. We dream big and iterate fast. If that sounds like home, we'd love to hear from you.

The role

As an AI engineer, you'll work in at the intersection of product, software and artificial intelligence. You'll work on orchestrating language models that we train in-house, data collection, curation, evaluating models, creating hand-crafted supervised fine-tuning data, developing preference optimization datasets, and model unit tests.

You'll contribute to our end-user product, improving user experience through your work on our models, data, and model orchestration. Some projects may include: LLM memory, manipulating training data using language models, improving our voice-to-voice UX, or working on our RAG stack.

You'll have the chance to work across the frontend, backend, ML and data stack. Partnering with a product team skilled in machine learning, alongside conversational designers, writers, and psychotherapists—all collaborating to deliver on our mission to the end-users.

Our tech stack includes Python for ML, React/TypeScript for the web, Kotlin for backend, and Flutter for mobile. You’re not expected to know all of those going in - but you will learn those tech stacks quickly. 

About you:

• You’ve shipped full-stack applications zero-to-one and have design-driven sensibilities.

• You’re fluent in multiple general-purpose programming languages (e.g. Kotlin, Swift, Typescript, Rust, etc.). You have an appreciation for what good code looks like, but you’re tech stack agnostic.

• You like being a generalist, and a team player, want to own what you build, love solving really hard problems, and are driven by building a world-class product.

• You can ship fast. We work at lightning speed.

Requirements:

• 3+ years of full-stack experience

• Experience with React, Typescript

• Based in NY

Why you should take this job:

• You really like to build. You can build prototypes really quickly. Your timeline to ship v1s is days, not months.

• You’re incredibly interested in how language models work. You’ve built at least a few side projects with LLMs and want to be at the cutting edge of the field.

• You want direct exposure and mentoring from a founding team with a successful exit and track record (Neil scaled Casper through IPO)

• You care about our mission, and are willing to do what it takes to make it happen

Why you shouldn’t take this job:

• You don’t like throwing code away

• You need clear guidance on every part of what you’re building.

You’ll learn a ton from experienced founders and teammates and work at an incredibly fast pace to ship, learn, and iterate. Even if you don't meet 100% of our criteria, we encourage you to apply if you think you can learn the rest on the job.

What we offer:

• A chance to join a passionate tight-knit team working on something to change the world

• Competitive compensation (90th percentile)

• Travel between our NYC / London offices

• Usual startup perks like free lunch in our offices + generous learning budget
