Role description
Our client is seeking a Senior Full Stack GenAI Engineer to help design, build, and deploy next-generation AI-driven applications. This hands-on role combines software engineering, architecture, and applied AI expertise to create scalable, secure, and modern solutions leveraging GenAI tools, LLMs, and AWS services.
The ideal candidate will have a strong full-stack foundation in Python and Java, extensive experience with microservices and CI/CD pipelines, and a passion for developing innovative AI-powered systems. This position offers the opportunity to shape the client's AI strategy and influence platform direction through experimentation, prototyping, and deployment of real-world GenAI applications.
Key Responsibilities
β’ Design and implement scalable GenAI architectures using large language models (LLMs), multimodal models, and retrieval-augmented generation (RAG).
β’ Develop and deploy AI-powered applications leveraging Python/Java, microservices, and cloud-native design patterns.
β’ Integrate AI and GenAI capabilities into enterprise applications using APIs, SDKs, and orchestration frameworks such as LangChain and Bedrock.
β’ Build and maintain CI/CD pipelines for AI and full-stack applications, ensuring automation, versioning, and efficient deployment.
β’ Fine-tune and optimize models using techniques such as instruction tuning, RLHF, quantization, and distillation.
β’ Experiment with emerging GenAI tools and frameworks (e.g., Hugging Face, LlamaIndex, DeepEval, RAGAS).
β’ Implement responsible AI practices, including bias detection, hallucination mitigation, and explainability.
β’ Collaborate with cross-functional product and architecture teams to align technical decisions with business goals.
β’ Stay ahead of industry trends and drive innovation within the GenAI and full-stack development ecosystem.
Required Qualifications
β’ 10+ years of total software engineering experience, including 5+ years full-stack development (Python/Java).
β’ 3+ years working directly with GenAI frameworks and tools (e.g., LangChain, Hugging Face, Bedrock, vector databases).
β’ Hands-on experience building and deploying GenAI applications in production environments.
β’ Strong background in modern architecture styles - microservices, APIs, and event-driven systems.
β’ Expertise with AWS services (SageMaker, Bedrock, Comprehend, Lex) or equivalent cloud platforms.
β’ Experience with CI/CD pipelines, containerization (Docker, Kubernetes), and ML workflow tools (MLflow, DVC).
β’ Strong understanding of LLMs, embeddings, and vector databases (e.g., FAISS, Pinecone, Weaviate).
β’ Excellent communication and problem-solving skills with the ability to work collaboratively in cross-functional teams.
Preferred Qualifications
β’ AWS AI/ML certification.
β’ Familiarity with AI testing frameworks such as DeepEval or RAGAS.
β’ Financial services or large enterprise environment experience.
β’ Knowledge of prompt engineering, few-shot learning, and agent-based systems.
Role Details
β’ Location: Hybrid (3 days onsite in Plano, TX - Tuesday through Thursday)
β’ Contract: 6-12 months (possibility of extension or conversion)
β’ Interview Process:
β’ MS Teams - Technical Screening (30 min)
β’ Onsite - 1 hour (includes coding)
