AI Solutions Engineer II

As a Software Engineer in the AI Solutions team, you occupy a unique techno-functional position. You are not a researcher; you are an implementation specialist and problem-solver. You bridge the gap between our core AI infrastructure and real-world customer impact. You aren't just writing code; you are applying data engineering, analysis, and AI knowledge to help global brands realize the full potential of AI-driven marketing.

Responsibilities 

• End-to-End Solution Delivery: Lead the full lifecycle of custom AI projects—from initial customer design and technical architecture to testing and production implementation.
• Production Stewardship: Take ownership of the "last mile" of delivery. This includes triaging technical tickets, analyzing logs (Datadog/Kibana), and debugging production issues in customer-specific AI workflows.

• Innovation & POCs: Develop Proof of Concepts (POCs) for AI experiments, benchmarking results to simplify and automate customer marketing ideas.

Requirements

• Software Engineering Fundamentals: 4+ years of experience in a production environment. Strong grasp of Object-Oriented Programming (OOP), Git, and the full SDLC.
• The "Polyglot" Mindset: Expert-level SQL and Python are mandatory. You must have the agility to work in Ruby and Scala/PySpark as the solution requires.
• Production Grit: Proven experience in a ticket-solving environment. You are comfortable navigating existing codebases to identify bugs, perform root-cause analysis, and deploy stable fixes.
• Analytical Mindset: You are a "Data Analyst with an Engineering heart." You enjoy digging into data tables to understand why a recommendation was made and how to optimize it.
• Customer Centricity: Experience working directly with customers or marketing teams. You can communicate technical concepts to non-technical stakeholders and manage project timelines independently.
• Experience Plus: Direct experience with Recommender Systems.

Nice to Have

• Direct experience with AWS Data Platforms, Jenkins, and Docker.
