STLabs is an AI service management platform that resolves employee requests end-to-end, grounded in a living model of the enterprise. This matters because we're able to resolve requests with full context - the people, systems, services, and policies that define how an organization actually runs. Requests that used to take days of back-and-forth resolve in minutes, right where employees already work

About the Role:
We’re looking for a Staff Software Engineer who thrives at the intersection of AI systems design, large-scale distributed infrastructure, and product innovation. You’ll lead technical initiatives that bring AI-native capabilities to life—building resilient, scalable systems that integrate LLMs, data-driven automation, and graph intelligence into enterprise workflows.

This is a hands-on leadership role for someone who codes deeply, mentors effectively, and loves shaping technical strategy in an AI-first environment.

Responsibilities:

• AI-Driven Systems Engineering

  • Design and develop AI-native architectures that embed LLMs and intelligent automation into ITSM and CMDB workflows.

  • Leverage LLMs, embeddings, and retrieval pipelines to power natural language interfaces, knowledge synthesis, and reasoning within our platform.

  • Collaborate with product, design, and data teams to infuse AI into every layer of the product experience—from backend systems to user-facing features.

  Technical Ownership

  • Own complex systems end-to-end: design, architecture, deployment, and production reliability.

  • Drive architectural decisions balancing near-term speed with long-term scalability and maintainability.

  • Help define our AI-first engineering stack and patterns for prompt orchestration, model integration, and continuous learning.

  Hands-On Engineering

  • Write clean, scalable, and testable code that pushes the boundaries of AI-enabled systems.

  • Design and optimize distributed, event-driven systems and APIs that handle data and inference at scale.

  • Conduct deep-dive code reviews and performance tuning across high-traffic, production environments.

  Leadership and Mentorship

  • Lead by example—uplifting code quality, fostering a culture of experimentation, and mentoring engineers in AI-augmented workflows.

  • Champion best practices in AI tooling adoption (e.g., Cursor, Windsurf, Claude) to enhance team productivity and creativity.

Qualifications:

• 7+ years of professional software engineering experience, with a record of delivering large-scale, high-impact systems.

• Deep expertise in distributed systems, cloud-native architecture, and API design.

• Hands-on experience with or strong interest in LLMs, vector databases, embeddings, or AI agent frameworks.

• Familiarity with prompt engineering, fine-tuning, and AI-powered developer tools.

• Experience mentoring engineers and guiding cross-functional teams toward technical excellence.

• Strong proficiency in one or more modern programming languages (e.g., Go, Python, Rust, or Java).

• Knowledge of Kubernetes, event-driven systems, and CI/CD best practices.

• A builder’s mindset: eager to explore, prototype, and ship fast.

What We Offer:

• Build foundational product features for an AI-first enterprise platform

• The opportunity to take ownership of critical systems that scale to millions of users

• A culture that values craftsmanship, autonomy, and technical excellence

• Competitive compensation, equity, and benefits package

• Work from our Midtown, Manhattan office, where you’ll be side-by-side with the founding team in a supportive, collaborative setting. Our team works on-site five days a week, growing and building together, and the location is easy to reach with plenty of public transportation options.
