What We Do
Remote Work Welcome
Be part of a transformative team that is shaping the way First American builds and delivers world-class technology products that fuel the real estate industry. We are looking for forward-thinking engineers who will envision, design, build, and deploy AI-native systems - from concept to production - that provide exceptional experiences and lasting value to our customers.
First American is seeking software engineering candidates to grow our team. An ideal candidate combines strong software engineering fundamentals with hands-on experience deploying LLMs and agentic systems into production. As a Senior Software Engineer, you will lead projects as part of a small, focused engineering delivery team, building intelligent, reliable software that drives meaningful business outcomes. You will be part of a transformative team whose mission is to modernize our core Title & Settlement Platform using modern architectures, cloud-native services, and production AI systems.
What You'll Do:

• Build & Deploy AI Systems (0 → 1): You will own the full lifecycle of LLM-powered features - from early prototyping and prompt design through production deployment, monitoring, and iteration. This includes fine-tuning workflows, building evaluation harnesses, and inference infrastructure that serve real users at scale. You will make pragmatic decisions and ship AI capabilities that are reliable, cost-effective, and measurably valuable.
• Agentic Systems Development: Design and implement autonomous agent architectures that reason, plan, use tools, and execute multi-step tasks with minimal human intervention. You will build orchestration layers, memory systems, guardrails, and feedback loops that enable agents to operate safely and effectively within business workflows. You will define agent behaviors, constraints, and failure modes - ensuring systems degrade gracefully and remain explainable.
• Code: You will be an active contributor to the codebase, designing, developing, testing, and deploying code supporting our most complex functional areas. Using agentic development, you will architect and implement modern services that are scalable, highly available, and fault-tolerant. You will build backend services and APIs that enable secure, reliable interaction between AI agents and internal or external systems. First American embraces AI as a core tool in our development process. You will use AI-assisted development tools (e.g., Cursor, Claude Code, Copilot) as part of your daily workflow, and help establish team-wide practices for agentic authoring - including prompt patterns, context management, and quality gates that maximize engineering velocity while maintaining code quality.
• Collaborate / Partner: Collaborate closely with product management, solution architects, AI/ML practitioners, and cross-functional teams to iteratively design, develop, and validate outcome-driven solutions. You will translate ambiguous business problems into well-scoped solutions, helping stakeholders understand what's feasible, what's risky, and what delivers the highest value.
• Operational Excellence: Implement solutions that are high quality, secure, observable, and production-ready. Establish evaluation strategies, cost monitoring, latency budgets, and guardrails that ensure AI systems behave reliably in production. Contribute to reviews of designs, code, artifacts, and metrics with a focus on both system performance and LLM usage efficiency.
• Continuous Improvement: Join a team determined to achieve ambitious goals by providing regular feedback, mentoring peers, and driving continuous improvement. Advocate for modern engineering practices that improve development velocity, system robustness, and long-term quality.

What You'll Bring:

• 5+ years of experience as a software engineer building production-grade systems
• Demonstrated experience taking LLM-powered features from prototype to production (0 → 1), including prompt engineering, evaluation, deployment, and iteration
• Hands-on experience building agentic systems - including planning/reasoning loops, tool use, memory/context management, and orchestration
• Strong experience building large-scale, back-end services and APIs using modern languages and frameworks
• Experience using AI-assisted development tools (Cursor, Claude Code, GitHub Copilot, or similar) as part of a modern software engineering workflow
• Solid understanding of LLM operational concerns: token economics, latency optimization, model routing, caching strategies, and cost management at scale
• Experience designing evaluation frameworks and quality metrics for AI systems (accuracy, hallucination rates, task completion, regression testing)
• Strong understanding of software engineering principles, cloud-native infrastructure, and distributed system design
• Ability to build robust, scalable, reusable solutions that safely integrate AI capabilities into core platforms
• Ability to mentor and influence other engineers, sharing knowledge and raising overall technical quality
• Ability to unblock yourself and help accelerate the team in achieving complex, cross-disciplinary goals
• Outcome-oriented mindset, using metrics and data to evaluate both system behavior and development effectiveness
• Experience driving engineering best practices for high-functioning teams through effective use of tools and automation
• Familiarity with deployment and observability strategies that support continuous delivery and high availability

Pay Range: $129,300.00 - $172,300.00 Annually
This hiring range is a reasonable estimate of the base pay range for this position at the time of posting. Pay is based on a number of factors which may include job-related knowledge, skills, experience, business requirements and geographic location.
