What We Do

We are looking for a hands-on Senior Software Engineer to serve as the technical owner for AI/ML initiatives within First American Technology. This role bridges business stakeholders, offshore delivery teams, and internal AI/ML platform teams to deliver production-grade AI-enabled applications.
This is not a solution architect or liaison-only role. The successful candidate is expected to write code, debug production issues, review deliverables, and ship improvements across AI/ML components and full stack application layers. You will own technical execution during US business hours, including coordination, incident response, and rapid resolution of business-impacting issues.

How You’ll Contribute

Technical Ownership & Delivery

• Own end-to-end technical execution for AI/ML application initiatives, ensuring delivery against scope, quality, and timelines.
• Translate business and functional requirements into clear technical designs and actionable engineering tasks for delivery teams.
• Coordinate execution across offshore teams, AI platform teams, and stakeholders; communicate status, risks, and dependencies.
• Review offshore deliverables (code, pipelines, infrastructure changes) for quality, performance, security, and compliance.
• Fully own projects in your area, identifying gaps/opportunities and driving solutions to completion.

Hands-On Engineering (Expected)

• Actively develop, test, and deploy production features across backend services, APIs, and UI integration.
• Provide maintenance of developed software including regression testing, debugging, and root-cause analysis.
• Build tools and produce technical documentation to improve developer efficiency and alignment.
• Build and maintain test automation suites and quality gates.

AI/ML & Generative AI

• Implement and support Machine Learning and Generative AI solutions, including LLM-based systems.
• Build and support Retrieval-Augmented Generation (RAG) pipelines and vector search integrations.
• Apply prompt engineering, LLM orchestration, and agentic workflow frameworks where appropriate.
• Support model/service evaluation, monitoring, and performance tuning (quality, latency, cost).
• Ensure responsible AI practices and governance standards are followed.

Cloud, DevOps & Operations

• Operate and support AI-enabled applications in Azure and/or AWS.
• Maintain CI/CD and operational pipelines (DevOps/MLOps) to enable reliable releases.
• Own production stability during US business hours: triage incidents, coordinate fixes, and implement long-term corrective actions.
• Ensure security, reliability, and cost awareness of deployed solutions.

What You’ll Bring

Required

• 5–8 years of overall software engineering experience, including full stack application development and production support.
• Advanced proficiency in Python and strong software engineering fundamentals (design, testing, debugging).
• Hands-on experience delivering AI/ML or Generative AI solutions in production (LLM-enabled apps, RAG, orchestration).
• Experience with RAG architectures and vector databases / vector search.
• Experience with cloud platforms (Azure and/or AWS).
• Strong troubleshooting, incident management, and root-cause analysis skills.
• Experience working effectively with distributed/offshore delivery teams.

Good to Have

• Bachelor’s or Master’s degree in Computer Science, Engineering, or related field.
• Financial services, insurance, or other regulated domain experience.
• Familiarity with CI/CD, containerization, IaC, and MLOps tooling.
