In this role, you’ll design, build, and deploy intelligent systems that solve real business problems; from LLM-powered applications and retrieval pipelines to predictive models and data-driven automation. You’ll bring together software engineering rigor and applied AI expertise to deliver production-grade solutions in client environments.
Whether your background is in software engineering, data science, machine learning engineering, or a blend of disciplines, this role is for builders who want to work at the frontier of applied AI: translating complex business challenges into scalable, reliable, AI-native systems that create measurable outcomes.
What You’ll Do
- Partner with clients and cross-functional teams to translate business problems into AI solutions, defining scope, success metrics, and technical approach
- Design, build, and deploy AI-enabled applications, services, and workflows, including LLM-powered systems, retrieval pipelines, and intelligent automation
- Develop and maintain the APIs, backend services, and data pipelines that power scalable AI and analytical systems
- Drive model evaluation, prompt engineering, data preparation, and system testing to ensure quality, reliability, and continuous improvement
- Contribute to infrastructure and deployment workflows for AI systems in cloud environments
- Strengthen engineering culture through code reviews, architectural documentation, mentoring, and evolving team best practices
What We’re Looking For
Required Qualifications
- Bachelor’s degree in Computer Science, Software Engineering, Data Science, or a related field
- 4+ years of professional experience in software engineering, data science, machine learning engineering, or a related technical discipline
- Demonstrated experience building and deploying AI-enabled or data-intensive production systems
- Experience with modern backend or data frameworks (e.g., FastAPI, Node.js)
- Strong experience with SQL and relational or analytical data systems
- Experience working in cloud environments (e.g., AWS, Azure, GCP)
- Familiarity with Git-based version control, CI/CD pipelines, and modern development workflows
- Strong written and verbal English communication skills
Preferred Qualifications
- Hands-on experience with LLM-powered applications, orchestration frameworks (e.g., LangChain, LangGraph), RAG architectures, vector databases, or prompt engineering techniques
- Background in applied machine learning, statistical modeling, or predictive analytics using modern frameworks (e.g., PyTorch, TensorFlow, Hugging Face, scikit-learn)
- Experience with the ML lifecycle — experimentation, evaluation, monitoring, and deployment (MLOps)
- Experience designing and maintaining large-scale data pipelines, analytical platforms, or data-intensive systems
- Familiarity with containerization, orchestration, or Infrastructure as Code technologies (e.g., Docker, Kubernetes, Terraform)
Why Join Xtillion
