AI EngineerLocation: San Francisco or New York City
About the RoleWe're hiring an AI engineer, a full-stack, strategic builder who can take a large project from a working prototype to an industry-defining product. You'll lead development of our agentic AI systems, owning model orchestration, retrieval, real-time inference, evaluation, and production infrastructure, and collaborating closely with the founding team on product and technical strategy.
What You'll Own- Build the engine: Design and own end-to-end agentic systems-retrieval, orchestration, inference, eval, and feedback loops
- Scale the stack: Shape our architecture across model interfaces, data pipelines, vector DBs, and streaming infrastructure
- Ship fast: Partner with product and design to prototype, test, and launch AI-driven features that deliver real value
- Improve performance: Continuously optimize accuracy, latency, and robustness through fine-tuning, eval frameworks, and data iteration
- Learn from the field: Join sales and customer calls to understand real-world pain points, pressure-test features, and translate feedback into product improvements
- Support growth: Build infrastructure and tools that help the whole company move faster-debugging, observability, agent testing
- Build your team: Hire, mentor, and collaborate with engineers who care about craft, velocity, and real-world impact
You Might Be a Fit If You...- Have 5-10 years of experience building AI or ML-powered systems, ideally in high-growth or early-stage environments
- Have shipped real products that use LLMs, retrieval, orchestration, or streaming inference-not just prototypes
- Think full-stack, end-to-end: You're comfortable moving between modeling, infra, and product-facing code
- Have an entrepreneurial mindset and thrive on building from scratch-systems, processes, tools, and the team
- Can explain complex ideas clearly, especially to non-technical teammates, customers, and stakeholders
- Thrive in ambiguity and take ownership in fast-paced, high-trust environments
- Bonus: Experience with vertical software businesses or agentic AI systems
What You'll Get- Competitive comp + meaningful equity
- Employee-centric benefits including:
- High 401(k( match and FSA program
- Modern, employer-paid health benefits designed to support you on your terms
- Real ownership, autonomy, and direct collaboration with the founders
- A chance to define a category and shape a product from scratch
- A hybrid culture anchored in SF and NYC-4 days a week in our Presidio HQ or our Williamsburg office on Domino Park-where you'll work side-by-side with the founding team, shape our rituals, and help create the moments and memories that define our company.
