Senior AI Software Engineer, Labs

Stylitics is a leading visual outfitting and styling solution for top retailers and brands. They are seeking an experienced AI Software Engineer to join their AI Labs, where the role involves combining software engineering expertise with AI model applications to drive innovation across 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. Experience building AI or LLM-powered products is a bonus
• 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 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
