Data Engineer Engineering

Why Delphi?

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.

What You'll Do

Build our data platform from 0→1 - Architect Delphi's entire data stack from scratch and turn raw data into insights that drive every major decision

Unlock product insights - Track user engagement with onboarding, identify "time to magic" moments, and discover behaviors that drive long-term retention

Drive growth intelligence - Analyze user segments, define session success metrics, and predict what actions lead to upgrades, churn, or virality

Optimize financial performance - Monitor paid tier performance, compare Free vs. paid user behavior, and refine pricing dynamics and conversion pathways

Run continuous experiments - Design and execute tests to learn about product behavior and find our north star metrics (like Duolingo's 3-day retention discovery)

Who You Are

0→1 data builder - You've built data infrastructure from scratch at a high-growth startup and know what it takes to go from nothing to production-ready systems

Technical foundation - Strong Python and SQL skills with proven experience designing scalable data pipelines, ETL systems, and data warehousing (Redshift preferred)

Cloud-native mindset - Comfortable with AWS infrastructure and building production-ready systems with strong reliability and observability practices

Analytics translator - You create clear, actionable dashboards and reports that non-technical teams use to make critical decisions

Bonus skills - You have deep experience with Amplitude for event instrumentation, building funnels, and extracting actionable product insights. Experience with distributed processing (Spark), event-driven architectures (Kafka), recommendation systems, or data science workflows is a plus

Why You'll Love It Here

We work on hard problems. Our team is full of former founders, and entrepreneurial individuals who are taking on immense initiatives.

There is extreme upside. Very competitive salary and equity in a company on a breakout trajectory.

We push each other. Work from our beautiful Jackson Square office in San Francisco, surrounded by peers pushing to do their best work.

Benefits

If you’re looking for just a job, Delphi isn’t the right fit. But if you want to shape the future of human connection, scale wisdom for billions, and build something that will outlast us all - you’ll feel at home here.
