Job Description

Why Delphi?

We are redefining how knowledge is shared. We are enabling anyone to transform their unique expertise into an interactive experience, a digital version of their mind: a dynamic reflection of their knowledge and perspective. This is a completely new medium of knowledge transfer designed to make human intelligence deeply engaging and infinitely scalable.

Imagine a world where the collective wisdom of individuals isn’t locked away, but is instead a dynamic, ever-evolving resource anyone can engage with. This is what we’re building: the platform and infrastructure for a future where human wisdom is abundant, learning and connecting is radically personalized, and individual brilliance can scale effortlessly.

2,800 years ago individuals from across the Greek world and beyond, including kings, city-state leaders, and ordinary citizens, made pilgrimages to Delphi , seeking guidance on matters ranging from war and politics to personal affairs.

And now people will come to Delphi again.

Our Supporters

We are proud of the coalition that we’ve been able to build behind Delphi.

• The best investors and angels you can find: backing from Sequoia, Founders Fund, Abstract Ventures, Michael Ovitz, Gokul Rajaram, Olivia Wilde and the founders of Lyft, Zoom, Doordash, and more.

• Incredible customers: we are a trusted and loved product by thousands of the world’s most brilliant minds. Tony Robbins to Codie Sanchez our customer base spans tens of millions of audience members.

• High talent density: we have put together exited founders, builders from Apple, Discord, Spotify, Substack and more, focused on our mission.

We have more than doubled our revenue, users, and delphi interactions in the last 6 months, all organically and through word of mouth, and we plan to accelerate even further from here.

What It Takes to Succeed at Delphi

Delphi is for those who want to be pushed to do their greatest work. We’re looking for those who don’t view their work as a job but rather they want to play a role in shaping the future of human connection, and leave a lasting impact.

This will work for you if:

• You are ambitious – Our team is full of former founders, and entrepreneurial individuals who are taking on immense initiatives. In a world of barrels and ammunition we are in search of barrels.

• You are obsessed – Being great doesn’t happen by accident . It is hard. You know that and it excites you. We value people who want to be great.

• You have a unique perspective, and tend to view the world positively – At the end of the day our product is a result of the collaboration of our team. We want people who are additive to culture. We value people who ask the question “What could go right?”

Your Mission

Architect and implement improvements to the backbone of our Delphi mind architecture. The architecture is powered by knowledge graphs that capture information about the person as well as their associations, reasoning patterns, and conceptual frameworks that make each mind unique. While traditional RAG systems treat knowledge as a flat collection of documents, we're building rich, hierarchical representations that mirror how human experts actually think and reason about their domains.

What You Will Own & Build

1. Graph Architecture & Design

• Design and implement scalable knowledge graph architectures that can represent both declarative knowledge and procedural reasoning patterns

• Develop novel graph embedding techniques that capture the nuanced relationships between concepts, experiences, and decision-making frameworks

• Create efficient indexing and retrieval mechanisms for real-time graph querying

1. RAG System Innovation

• Build next-generation retrieval systems that combine traditional RAG with graph-based reasoning

• Implement hybrid architectures that seamlessly integrate symbolic graph operations with neural retrieval

• Develop evaluation frameworks to measure and optimize retrieval quality across different types of queries

1. Knowledge Integration & Maintenance

• Design systems for automated knowledge graph construction and maintenance from various data sources

• Implement validation and consistency checking mechanisms to ensure graph quality

• Create tools for experts to review and refine their knowledge representations

1. Infrastructure & Scaling

• Build infrastructure for distributed graph operations across thousands of clone instances

• Optimize graph operations for low-latency retrieval in production environments

• Develop monitoring and debugging tools for graph-based reasoning systems

What We’re Looking For

• Graph Expertise: Deep experience with graph databases, knowledge graphs, and graph neural networks

• RAG Systems: Strong background in retrieval-augmented generation, including both traditional and graph-based approaches

• Neural-Symbolic Systems: Experience combining symbolic reasoning with neural networks

• Distributed Systems: Ability to design and implement distributed graph processing systems

• Python & Graph Tools: Proficiency with Python and graph processing frameworks (Neo4j, DGL, PyG, etc.)

• Research Translation: Proven ability to translate academic research into production-ready systems

• First Principles Thinking: Capacity to reason about and solve novel technical challenges without established playbooks

Why You Might NOT Like Working at Delphi

• High Expectations: We demand excellence. If you’re not comfortable with high standards, constant iteration, and direct feedback, this environment may not align with your working style.

• In-Person Collaboration: We believe in-person collaboration drives better ideas. If you thrive in a remote-first environment, this may not be the best fit.

• Ambiguity & Uncertainty: Many of our challenges don’t have obvious solutions. If you’re not comfortable navigating ambiguity or tackling problems without previous solutions this might not align with your working style.

• Not a 9-to-5: We move fast, iterate often, and tackle ambitious challenges. This isn’t a clock-in/clock-out environment.

What You Would Get

• Excellent team: We have worked hard to put together some of the most ambitious, creative, smart people that we have met. They want to get to know you and work with you.

• Equity: We are confident that this opportunity is massive, and we want you to share in the upside.

• Unlimited Learning Stipend: Whether it’s books, courses, or conferences, we want to support your growth and development. The more you learn and improve your craft the more effective we will be together.

• Health, Dental, Vision: Comprehensive coverage to keep to take care of your health.

• In-Person Office: Work from our beautiful office in Jackson Square, San Francisco. We believe that learning through osmosis, in-person, is the best way to learn.

• Ascension: We’ll push you to do the greatest work of your life, with opportunities to grow both personally and professionally.
