Principal AI Engineer

• Systems-Oriented Technical Leader: You think in systems, not features. You make strong architectural decisions, navigate trade-offs effectively, and help shape technical direction across teams. • Systems-Oriented Technical Leader • Applied Agentic AI Builder: You’ve built and scaled production agentic AI systems that perform meaningful work beyond simple chat interfaces. You understand agent behavior, tool orchestration, stateful workflows, and the realities of operating AI systems in production. • Applied Agentic AI Builder • Product-Minded Engineer: You work closely with product managers and domain experts to define problems and translate ambiguity into clear technical solutions. You care about outcomes, not just implementation. • Product-Minded Engineer • Strong Judgment in Ambiguity: You’re comfortable operating in evolving problem spaces, balancing experimentation with reliability and knowing when to prioritize speed versus long-term investment. • Strong Judgment in Ambiguity • Data & Evaluation Driven: You use metrics, evaluation frameworks, and operational feedback to guide decisions and continuously improve system performance. • Data & Evaluation Driven: • Highly Autonomous Executor: You take ownership of complex problem spaces end-to-end, balancing speed with engineering rigor and iterating effectively based on real-world feedback. • Highly Autonomous Executor • Multiplying Presence: You elevate those around you — mentoring engineers, establishing best practices, and helping raise the bar for how AI systems are designed and operated. • Multiplying Presence • 6+ years of experience building and shipping production software systems, including experience operating at a Staff or Principal IC level and driving technical direction across complex systems • Proven experience building and scaling multi-agent or agent-driven systems in production and real-world operational ownership (beyond simple chat or LLM workflows). • Hands-on experience with modern agent ecosystems, including frameworks (e.g., LangGraph, Mastra, Claude Agents SDK), observability/evals tooling (e.g., Langfuse, LangSmith, Braintrust), MCP implementations, and leading AI SDKs (e.g., OpenAI, Anthropic). • Strong systems and backend architecture fundamentals, with experience designing scalable, reliable systems and handling infrastructure, performance, failure modes, cost, and deployment concerns. • Clear agentic evaluation mindset, including automated evals, simulation-based testing, regression frameworks, metrics design, and continuous improvement loops. Firsthand experience addressing performance and reliability of scaled agentic systems. • AI-native builder with high velocity and ownership, demonstrating intellectual curiosity, rapid adoption of new tools, bias to action, and the ability to drive ambiguous problems from concept to production. • Strong cross-functional collaborator and communicator, able to partner with Product, Operations, and domain experts to deliver end-to-end systems with measurable real-world impact. • Force-multiplier technical leader, raising the bar for clarity of thinking, system design standards, and team execution. • Experience building conversational or voice-driven systems (e.g., speech pipelines, telephony integrations, or real-time conversational workflows). • Experience working in healthcare or other regulated or high-stakes domains. • Our Values • Our Values • Lead with integrity: We keep our commitments and take responsibility for our actions. We are dependable and choose authenticity over perfection. • Lead with integrity: • Embrace challenges: We leave our egos at the door and step forward into discomfort instead of back into safety. We help each other to learn and provide feedback using candor and kindness. • Embrace challenges: • Break through walls: We go the extra mile for our patients, partners and one another, and we run toward hard things. We are resilient in our push for consistent improvement and challenge the status quo. • Break through walls: • Act beyond yourself: We build each other up and respect boundaries. We seek first to understand and assume positive intent. • Act beyond yourself: • Care comes first: We hold ourselves to the highest standards for our patients. We are relentless in the pursuit of our mission, and ensure that we are taking care of ourselves in order to care for others. • Care comes first: • Because We Value You • Competitive salary: $240,000 - 260,000 • Equity compensation package • Flexible vacation policy – take the time you need to recharge • Comprehensive medical, dental, and vision coverage • 100% company-sponsored short and long-term disability and life insurance • Subsidized backup childcare and caregiver supports through Wellthy • Work entirely from the comfort of your own home • Monthly $100 work from home expense stipend • We provide the equipment needed for the role • Opportunity for rapid career progression with plenty of room for personal growth! • Travel reimbursements for any company retreats or leadership offsites
