Role

Who you are

You’ve shipped web applications zero-to-one and have design-driven sensibilities
You’re fluent in multiple general-purpose programming languages. 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
3+ years of full-stack experience
Experience with React, Typescript, and CSS
Based in NY/London

What the job involves

You will be the lead developer for Slingshot's Data Platform, used for training and aligning conversational models and agents for the psychology domain
You'll work with a team of predominately ML engineers to implement features that lead to the best experience for 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
In this role, you’ll truly be working full-stack. You will be your own product manager and designer, taking on difficult problems and solving them through a ruthlessly experimental mindset
You'll primarily be working with NextJS (Typescript, Vercel, Supabase)
You'll also interact with our Kotlin backend, Flutter mobile app, and python machine learning services
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
You’ll learn a ton from experienced founders and teammates and work at an incredibly fast pace to ship, learn, and iterate

Our take

Use-cases of machine learning in the previous three decades have gone from the impressive but impractical achievements of beating Chess Grand Masters to being integral to some of the world’s most used commercial applications like Google Search.

Slingshot is taking Large Language Models in a new direction, using its machine-learning tools to train generative AI in deep psychology. The aim is to build machine learning models that can perform modern therapy through Ash, set to be the first AI counselor, driving down the cost of mental healthcare.

Slingshot is attempting to democratize access to mental health care through the increasingly complex capabilities of ML. What started for Slingshot as a general exploration of machine learning has developed into a potentially significant and singular product. Whilst the proof will be in the pudding, Ash still being in development, Slingshot has won investor confidence evidenced by its $6 million seed fundign round in 2022.
