You will partner closely with Product and Engineering leadership to translate business objectives into scalable, well-architected AI solutions. This role combines deep hands-on development with architectural leadership: setting technical patterns, guiding major initiatives from design through delivery, and ensuring our AI services are reliable, performant, and cost-aware in production.

• Drive rapid experimentation and prototyping (often in Python), ensuring clear paths to production-ready implementations

• Define and enforce standards for evaluation, cost-awareness, and operational reliability across AI systems

• Mentor Senior AI Engineers through design reviews and technical guidance

• Collaborate with Staff Engineers when broader architectural alignment is required

How You’ll Work

• Work directly with Product Managers and stakeholders to clarify goals and define measurable success criteria

• Balance hands-on engineering with architectural oversight

• Ensure architectural consistency and adherence to established design standards

• Raise the technical bar through thoughtful reviews and shared engineering standards

Who You Are:

• 7+ years of professional software engineering experience

• Strong proficiency in Go (GoLang) and experience building production-grade, API-driven services

• Proficiency in Python for experimentation, prototyping, and scripting

• 3+ years of experience building and deploying AI/ML systems in production environments

• Strong experience with modern LLM ecosystems (e.g., OpenAI, Anthropic, Hugging Face)

• Deep understanding of LLM-based solution patterns, including Retrieval-Augmented Generation (RAG), structured outputs, schema-driven generation, and agents/orchestration workflows

• Familiarity with MCP (Model Context Protocol) servers and orchestration approaches

• Experience evaluating LLM performance in production contexts, including prompt design, quality measurement, and model comparison

• Experience designing and operating scalable API services at scale

• Strong experience with cloud infrastructure (AWS, GCP, or Azure)

• Experience with vector databases and inference systems

• Strong SQL skills and familiarity with modern data storage technologies

Nice to Have

• Experience working with large taxonomies or structured classification systems

• Experience in e-commerce, product catalogs, or sales channel data models

• Familiarity with frontend frameworks (React, Angular)

What Success Looks Like

• AI initiatives ship with strong architectural integrity and measurable business impact

• AI services are scalable, reliable, and cost-aware in production

• Clear architectural direction is reflected in design decisions and implementation standards
