Job Description
*Overview*
We are looking for a hands-on Full-Stack AI Engineer who enjoys building real products end-to-end. In this role, you will develop features across the web UI, backend services, and AI pipelines while working directly with clients to translate testing workflows into scalable product features.
This is a builder role — not a planning-only role. You will be writing production code daily across multiple codebases including React frontend applications, Python services, and PHP systems.
*What You’ll Do*
* Build and ship full-stack product features from concept to production
* Develop web application features such as dashboards, test run viewers, diff tools, and reporting tools
* Design and build backend APIs including job orchestration, data storage, authentication, and third-party integrations
* Develop and maintain AI pipelines including LLM integrations, RAG workflows, structured data extraction, and evaluation/verification loops
* Integrate automation tooling such as Appium, WebDriver, WDA, and device logging systems
* Partner directly with customers and internal teams to turn real testing workflows into product capabilities
*Required Qualifications*
* 3+ years of experience building and shipping production software applications
* Strong full-stack engineering fundamentals (HTTP, REST APIs, authentication, databases, caching)
* Frontend experience with React and TypeScript
* Backend experience with Python and PHP
* Experience working across multiple services and codebases
*Preferred / Nice to Have*
* Experience working with LLM integrations (OpenAI APIs, prompt engineering, evaluation frameworks, internal tooling)
* Experience with RAG architectures, embeddings, and vector databases (FAISS, pgvector, Pinecone, or similar)
* Experience with media processing (image diffing, OCR, or visual testing systems)
* Experience with mobile automation (Android, iOS, Appium, Selenium, or similar frameworks)
*What Success Looks Like*
* Shipping production-ready features consistently
* Writing clean, maintainable, and scalable code
* Translating customer workflows into technical solutions
* Contributing across frontend, backend, and AI systems
Job Type: Full-time
Pay: $47.00 per hour
Expected hours: 40 per week
Benefits:
* 401(k)
* Dental insurance
* Health insurance
* Health savings account
* Paid time off
* Vision insurance
Work Location: In person
