About the Role

We're looking for an AI Engineer II to design and ship internal AI-powered tools end-to-end. You'll own AI-powered applications, workflow automations, and integrations from concept through production, evaluating and integrating new AI capabilities as you go. This is a hands-on building role: you'll write production code, not just prototype it, while partnering with business stakeholders and growing into fuller ownership at the next level.

Responsibilities

• Design and build internal AI-powered tools and web applications end-to-end, including front-end, back-end, data, API, and LLM/AI integrations.
• Own AI applications, workflow automations, and systems integrations from requirements gathering and technical design through production deployment and iteration.
• Partner with Sales Operations, Revenue Analytics, and cross-functional stakeholders to translate business problems into scalable technical solutions that deliver measurable value.
• Evaluate and integrate new AI models, APIs, frameworks, and development approaches based on business needs, technical feasibility, and performance.
• Develop production-quality applications with appropriate testing, documentation, monitoring, and maintainability; troubleshoot and improve solutions post-launch based on user feedback and performance.
• Build reusable AI capabilities, integrations, documentation, and development patterns that can be leveraged across teams and use cases.
• Communicate technical concepts, solution designs, tradeoffs, and outcomes to technical and non-technical stakeholders, including presenting work to cross-functional audiences.

Qualifications

Required

• 1–2 years of hands-on experience building software, data products, or AI-powered tools through professional, internship, academic, or substantial independent project experience.
• Strong proficiency in Python and SQL, with experience in data analysis, application development, and statistical or machine-learning workflows.
• Hands-on experience with machine learning and statistical modeling, including regression, classification, feature engineering, and model evaluation.
• Experience working with large structured datasets using Snowflake, relational databases, or comparable cloud data platforms.
• Experience developing or integrating REST APIs and backend services using FastAPI or similar frameworks, along with familiarity with modern web application development.
• Demonstrated ability to ship functional tools or applications to real users and evaluate their performance using appropriate technical or quantitative measures.
• Strong problem-solving, communication, and collaboration skills, including the ability to learn unfamiliar technologies, incorporate stakeholder feedback, and explain technical tradeoffs to non-technical audiences.

 

Preferred

• Experience developing applications using LLMs, RAG, embeddings/vector search, prompt engineering, and LLM APIs such as OpenAI or Anthropic.
• Familiarity with AI agents, tool/function calling, intent routing, retrieval systems, and workflow orchestration.
• Experience with React and TypeScript or another modern front-end framework.
• Experience with Docker, AWS, or comparable cloud and deployment technologies.
• Familiarity with ETL/ELT pipelines, data modeling, JSON/metadata mappings, and multi-system data integrations.

• Experience with Snowflake, Salesforce, or other GTM/revenue data systems.

Logistics
