Software Engineer (AI/ML)

We're a team of machine learning and product engineers training task-specific generative models for psychology. Our mission is to use AI to make mental healthcare more accessible and to help people change their lives in the ways they want. We partner with organizations around the globe and power use cases, including AI-assisted crisis text response and AI counseling, 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 a member of our early team, you'll work directly on our product and the AI tooling behind our product with our machine learning team. You'll work on orchestrating multiple language models that we train in-house. You'll work on tooling that supports our data collection, curation, ablation studies, evals, creation of hand-crafted supervised fine-tuning data, and preference optimization. You'll contribute to our end-user product, improving user experience through your work on our models and model orchestration.

In this role, you’ll truly be working full-stack. You'll work with a team of predominately ML engineers, all working together for our end-users who are going through mental health challenges. You'll also work with conversational designers, writers, and psychotherapists who interact with our tools to develop our product experience.

You'll primarily be working with NextJS, our ML services in python, our Kotlin backend, and our Flutter mobile app. You'll be working with custom in-house language models along with voice models (text-to-speech and speech-to-text) and large language models.

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 typed code looks like and have 3+ years of experience as a software engineer.

• You have experience with modern backend technologies and architectures like microservices, message queues, caching layers, and SQL/NoSQL databases.

• You like being a generalist, 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, and CSS

• Based in NY or London

What We Offer

• Competitive compensation (90th percentile)

• Hybrid environment, highly collaborative, fast-paced culture

• Unparalleled growth opportunity - learn faster than you would anywhere else

• Work with a passionate team that cares about the future of mental health, especially in a post-AGI world

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.
