About The Position

At Delphi, we are redefining how knowledge is shared by creating a new medium for human communication: interactive digital minds that people can talk to, learn from, and be guided by. The internet gave us static profiles and endless feeds. Delphi is something different: a living, interactive layer of identity. It carries your voice, perspective, and judgment into every conversation—so people don’t just read about you, they experience how you think. Our mission is bold: Make human wisdom abundant, personalized, and discoverable. Preserve legacies, unlock opportunities, and scale brilliance across generations. Delphi becomes everyone's living profile to show what you know. We are trusted and loved by thousands of the world’s most brilliant minds from Simon Sinek to Arnold Schwarzenegger (interact with all of them here). We have tripled revenue, users, and Delphi interactions in the past 6 months - all organically through word of mouth. We plan to accelerate even further from here. Delphi’s investors include Sequoia Capital, Founders Fund, Abstract Ventures, Michael Ovitz, Gokul Rajaram, Olivia Wilde, and dozens of founders from Lyft, Zoom, Doordash, and many more. Our team includes founders with successful exits and builders from Apple, Spotify, Substack and more. Learn more about Delphi and this position by calling the CEO’s digital mind here What You'll Do As our Platform Engineer, you'll own three critical pillars: data platform, developer platform, and product platform. This isn't a traditional infrastructure role - you'll be architecting the systems that enable our team to move fast while maintaining reliability at scale. You'll build the foundations that power everything from our real-time AI interactions to our analytics pipelines, from CI/CD to observability.

Requirements

Systems thinker: You audit systems holistically and implement unified standards rather than one-off fixes. You have 5+ years building and scaling production infrastructure with experience in observability, monitoring, and incident response at scale.
Speed enabler: You believe great platform engineering means teams can move fast without breaking things. Background in fast-growing startups (0-1 or scaling phase).
Generalist builder: You're comfortable moving between data pipelines, infrastructure automation, and DevOps tooling - whatever the platform needs. Deep experience with data infrastructure (warehouses, ETL/ELT pipelines, analytics systems) and strong foundation in cloud platforms (AWS preferred) and infrastructure-as-code.
Scale-minded: You anticipate infrastructure needs before they become bottlenecks and own the evolution of systems as we scale. Track record of improving developer velocity through better tooling and workflows.
Standards-driven: You define and enforce critical standards around data governance, customer privacy, and security best practices - with comfort in ambiguity and the ability to define what needs to be built.
