Full Stack Software Engineer, AI Features

At Skylight, we thrive on innovation and creativity, building products that bring families closer together. As a Full Stack Engineer within our new AI products team, you'll be at the forefront of developing features that enhance user experiences across our platforms. This is a unique opportunity to work on both the frontend and backend aspects of our applications, contributing to a product loved by millions of users.

We're looking for a high-speed, product-minded, entrepreneurial Full Stack Software Engineer (Senior, Staff, or Principal level). In this role, you will work directly with our GM of New Businesses to build out new AI-powered features across our platform. You’ll build primarily in Ruby on Rails and occasionally in Typescript (React and React Native), integrating with LLMs from vendors like OpenAI. You should have deep expertise in both front-end and back-end technologies, with mastery of Ruby on Rails or a similar back end language and at least a working knowledge of (and willingness to learn) Typescript/React Native, and you should have at least some cursory experience building features that leverage Gen AI/LLM APIs.

Responsibilities

• Design, build, and launch new user-facing features powered by large language models (LLMs)
• Own major product initiatives from zero-to-one, in partnership with a small but mighty team
• Collaborate with Product and Design to shape new products and features: bringing your creativity and ingenuity to our roadmap as well challenging assumptions, refining scope, and helping us ship elegant, focused, customer-centric MVPs and iterations.
• Integrate with third-party APIs like OpenAI and explore new model capabilities
• Build exciting new features in Ruby on Rails, Typescript, React Native, and whatever other languages/technologies we adopt to best serve the needs of our customers
• Write code that is simple, clean, tested, and pragmatic: fast enough to validate, solid enough not to drag us down later, and scrappy enough that we’re willing to throw it away.
• Mentor other engineers through code reviews and design discussions

• 6+ years experience building software products end-to-end
• Strong product intuition. You know how to dial in on what an MVP should deliver or learn, and craft the simplest path to get there.
• Bias toward action and autonomy: you thrive when given trust and ownership.
• Exceptional verbal and written communication. You are able to make the technical accessible and inspire confidence regardless of the audience
• Deep experience in Ruby on Rails (or similar backend frameworks) and working knowledge of Typescript/React
• Demonstrated ability to ship zero-to-one products as a solo engineer or team lead
• At least side-project experience working with LLM APIs and enthusiasm for developing Gen AI applications
• Remote startup experience strongly preferred

Nice to Haves

• Professional experience building features with OpenAI, Anthropic, or similar LLM APIs
• Familiarity with prompt engineering or retrieval-augmented generation (RAG)
• Prior work on family-facing or consumer products
