• Design scalable Snowflake-backed workflows, including SQL transformations, stored procedures, Snowpark or Python-based processing, and performance optimization.
• Architect and implement GenAI and AI-powered product capabilities, including role-based agents, retrieval-augmented generation, prompt workflows, AI-assisted analysis, customer-facing copilots, and internal productivity tools.
• Prototype new AI use cases quickly, evaluate technical feasibility, and move promising experiments into secure, reliable, production-ready services.
• Collaborate with Salesforce engineers to design integration patterns using Platform Events, APIs, async processing, and well-defined data contracts between Salesforce, AWS, and Snowflake.
• Support predictive and ML-enabled use cases such as lead scoring, buyer scoring, property intelligence, recommendation workflows, anomaly detection, and customer insights.
• Improve reliability, observability, and operational maturity across backend systems through structured logging, monitoring, alerting, automated tests, and clear incident response practices.
• Contribute to CI/CD, infrastructure automation, environment management, and deployment practices for backend and data services.
• Bring ideas, technical curiosity, and product-minded thinking to roadmap discussions, architecture reviews, and innovation planning.

Requirements

• 2+ years of professional backend engineering experience building production-grade APIs, services, data workflows, or cloud-native systems.
• Strong hands-on experience with Python for backend development, scripting, automation, data processing, or AI/ML workflows.
• Experience building RESTful APIs and integrating systems through APIs, webhooks, event-driven patterns, or message-based architectures.
• Strong working knowledge of AWS, especially serverless or cloud-native services such as Lambda, API Gateway, S3, IAM, CloudWatch, EventBridge, SQS, SNS, Kinesis, or similar technologies.
• Strong SQL skills and experience working with modern data warehouses, preferably Snowflake.
• Experience designing systems that are reliable, secure, observable, cost-conscious, and maintainable.
• Familiarity with modern AI and GenAI development patterns, such as LLM APIs, prompt engineering, RAG, embeddings, vector databases, model evaluation, agent workflows, or AI-assisted automation.
• Ability to use modern AI development tools such as ChatGPT, Claude, Cursor, GitHub Copilot, or similar tools to improve development speed, code quality, documentation, and problem solving.
• Experience working with CI/CD pipelines, GitHub Actions, automated testing, infrastructure-as-code, or deployment automation.
• Comfort working in a fast-moving startup environment where priorities evolve and engineers are expected to own outcomes, not just tickets.
