Principal Software Engineer, AI

Principal Software Engineer, AI

Salesloft is building the next era of enterprise revenue by combining AI and real signals. As a Principal Software Engineer, AI, you will architect systems that turn LLMs, machine learning models, and agentic workflows into production capabilities that thousands of enterprise revenue teams depend on.

Responsibilities

• Set the technical architecture and direction for AI systems across the platform — model serving, LLM-powered features, agentic workflows, and the infrastructure beneath them.
• Design production-grade systems that are reliable and observable despite being built on non-deterministic, probabilistic AI components.
• Architect evaluation frameworks, guardrails, and quality systems that make AI behavior safe, measurable, and trustworthy at enterprise scale.
• Lead the most complex AI engineering problems end to end — from research-adjacent prototyping through hardened production delivery.
• Establish engineering standards and best practices for building AI-native systems, and mentor senior engineers across the org.
• Keep the platform at the frontier by evaluating and integrating advances in foundation models, agent frameworks, and the modern AI stack.

Requirements

• Extensive experience building and architecting production software systems at scale, with significant depth in AI/ML systems.
• Hands-on experience building production systems on top of LLMs or machine learning models — including designing for the challenges of non-deterministic behavior.
• Deep expertise in distributed systems, model serving, and the infrastructure required to run AI reliably at scale.
• Proven experience designing evaluation frameworks, guardrails, or quality systems for AI-driven features.
• A track record of setting technical architecture and standards across teams and mentoring senior engineers.
• Strong command of a major programming language (e.g., Python, Java, or Go) and modern cloud infrastructure (AWS or GCP).
• Hands-on experience with agentic systems — designing and hardening AI agents that take autonomous action in production.
• Depth in the modern AI stack — retrieval-augmented generation, vector stores, agent frameworks, model orchestration, or evaluation tooling.
