AI Engineer (DFW Hybrid)

About the position RealPage is at the forefront of the Generative AI revolution, dedicated to shaping the future of artificial intelligence within the Property Tech domain. Our Agentic AI team is focused on driving innovation by building next generation AI applications and enhancing existing systems with Generative AI capabilities. We are seeking an AI Engineer to help us with the development, deployment, and scaling of advanced AI applications that address real-world challenges. In this role, you will focus on designing, building, and scaling advanced AI applications in the PropTech space. You will work with state-of-the-art foundation models, RAG architectures, and multi-agent systems while partnering closely with product, design, and engineering teams. You will be responsible for taking AI concepts from ideation to production, owning end-to-end solutions that improve our products and transform user experiences.

Responsibilities

• Evaluate and use LLMs and multimodal models from multiple providers (e.g., OpenAI, Google, Anthropic, etc.) for conversational assistants, task-based copilots, and AI agents; summarization, content generation, document understanding, generative analytics; and basic multimodal use cases (text + image, text + document, and soon video/audio).
• Design and implement agentic workflows (e.g., tool-calling, multi-step reasoning, multi-agent orchestration) using LangChain, OpenAI Agents SDK, Google ADK or similar frameworks.
• Design and optimize prompts and system instructions to improve task completion, reliability, and latency, and minimize hallucinations and toxic/unsafe outputs.
• Implement structured outputs (JSON/JSON Schema) and develop function/tool calling and prompts that help AI call them properly.
• Integrate safety/guardrail layers (e.g., content moderation APIs, Guardrails AI, Rebuff, custom policies) to keep conversations focused.
• Architect and implement RAG pipelines, including choosing and configuring vector databases (e.g., PGVector, Vertex AI Search, Pinecone, etc.), building ingestion pipelines for internal data (documents, tickets, logs, property data, etc.), and implementing knowledge retrieval processes that draw from multiple sources and use reranking to improve response quality.
• Explore emerging retrieval techniques (semantic caching, knowledge graphs, long-context models, memory systems).
• Build or integrate front-end experiences (React / Vue / Svelte / Web RTC) for AI agents and copilots.
• Develop back-end services to orchestrate AI calls using REST, gRPC, WebSockets, or MCP; ensure scalability and observability.
• Integrate with internal systems and PropTech data sources using secure APIs and data contracts.
• Design and maintain evaluation pipelines and benchmarks for LLM-based features, including offline metrics (accuracy, relevance, latency, cost) and human-in-the-loop evaluations where needed.
• Use AI observability and tracing tools (e.g., LangSmith, OpenTelemetry, etc.) to monitor quality.
• Optimize for performance, reliability, latency, and cost through model selection and routing (e.g., small vs. large models, Google vs. OpenAI) and prompt/token optimization and caching strategies.
• Collaborate with cross-functional teams (Product, Design, Domain Experts, Data Science, Platform Engineering) to define requirements and success metrics.
• Participate in architecture and design reviews; write clear technical documentation and runbooks.
• Contribute to shared libraries, templates, and best practices for AI development.
• Work in an Agile environment and own features from design through deployment and maintenance.

Requirements

• 3+ years of total experience in Software Engineering and/or Data Science, with at least 1+ years focused on Generative AI/LLMs.
• Degree in Computer Science, Machine Learning, Data Science, or related field, or equivalent practical experience.
• Strong proficiency in Python for AI/ML, data pipelines, and back-end services.
• Strong proficiency in JavaScript/TypeScript for front-end and/or Node services.
• Strong proficiency in SQL and experience working with relational databases and basic data modeling.
• Working with coding assistants like Windsurf, Cursor, Codex, etc.
• Proven experience building production-grade software: Writing clean, testable, maintainable code; Using CI/CD pipelines, code reviews, and Git workflows.
• Hands-on experience with at least one agentic/orchestration framework (OpenAI Agents SDK, Google ADK, LangChain, etc.).
• Hands-on experience with LLM APIs and/or open-source models (e.g., via OpenAI, Google, Hugging Face, Ollama).
• Hands-on experience with Vector embeddings, vector databases, and RAG architectures.
• Experience with one or more major cloud platforms (GCP, Azure, and AWS).
• Experience with Docker for containerization.
• Experience with Kubernetes or a managed container service (e.g., EKS, GKE, AKS).
• Strong communication skills and ability to collaborate with both technical and non-technical stakeholders.

Nice-to-haves

• Experience with voice-enabled AI agents (STT, TTS, WebRTC, Twilio Voice, Socket.IO, VAPI).
• Experience with multimodal models (e.g., GPT models including Realtime, Gemini Pro Vision, etc.).
• Experience orchestrating multiple models (routing, ensembles, fallback strategies).
• Familiarity with AI experiment tracking and evaluation frameworks (e.g., OpenAI Evals, Langsmith Evals, etc.).
• Familiarity with Feature stores, data versioning (e.g., Feast, DVC), and MLOps workflows.
• Familiarity with Browser automation software such as PlayWright.
• Background in AI security, privacy, and compliance (PII handling, SOC2, GDPR considerations).
• Background in A/B testing and online experimentation for AI features.

Benefits

• Health, dental, and vision insurance.
• Retirement savings plan with company match.
• Paid time off and holidays.
• Professional development opportunities.
• Performance-based bonus based on position.
