Senior AI Software Engineer

Stylitics is the leading visual outfitting and styling solution for top retailers and brands. They are seeking a Senior AI Software Engineer to join their AI Labs, where the role involves developing innovative AI model-based applications and prototypes for various retail use cases.

Responsibilities:

• Write production-level code in TypeScript (with AI tools)
• Build full-stack prototypes, including front-end interfaces that demonstrate capability to stakeholders and clients
• Prompt engineering and testing with LLMs, including Claude, Gemini, and OpenAI models
• Context engineering to determine the right data to surface to LLMs and agents
• Agentic workflow design
• Help us build systems to easily monitor and test LLM performance
• Analyze large data sets
• Design and implement solutions for scale and maintainability across multiple clients
• Contribute as a thought leader to conversations around LLM usage, including challenging or proposing technical directions and identifying what to worry about (and what not to) early in a project

Requirements:

• Bachelor's Degree from an accredited college or university in Computer Science, Data Science, Statistics, or other related fields, or equivalent experience
• 7+ years of software development experience, including work within retail, e-commerce, or another applied AI/technology industry
• Confident communication (written and oral) skills and a demonstrated ability to work collaboratively with all levels of internal and external organizations
• Strong asynchronous written communication is essential, Labs works across time zones and with small, distributed teams
• Strong problem-solving, attention to detail, organizational, and time management skills along with demonstrated strategic thinking abilities
• Working experience with modern prototyping stacks, specifically React, TypeScript, and SQL, sufficient to stand up a working UI backed by a real data model
• Experience with LLMs, testing, and prompt engineering, including work with Claude, Gemini, and OpenAI APIs
• Demonstrated affinity for and experience with agentic software engineering — either on the job or on your own time. We expect you to be enthusiastic about using AI coding tools in your day-to-day work
• Solid understanding of system design, scalability principles, use of APIs, and open-source packages
• Demonstrated ability to evaluate model performance using structured test cases and metrics
• Ability to operate independently with ambiguity in product definition
• Judgment to know when to trust an LLM's output and when to challenge it — a foundation of actual engineering knowledge and experience, not just the ability to look things up
• Experience building AI or LLM-powered products is a bonus
• Experience at a high-growth start-up and comfortable with the unknown
• Working experience with building test workflows for LLMs
• Familiarity with additional programming languages such as Java or Python for data processing or AI prototyping
