Founding Engineer

Pear VC • Palo Alto, CA

3d • $150,000 - $250,000 • Onsite

About The Position

Blueberry is building the 1:1 marketer for the world’s most ambitious brands. The way brands engage with customers is fundamentally shifting. In the early days, founders reply to every comment, DM every follower, and know customers by name. But as audiences grow into the hundreds of thousands or millions, that intimacy breaks. Even with social managers, no team can authentically know every follower, so brands default to 1:many channels like mass email, SMS, and generic posts. The personal touch disappears.
At Blueberry, we’re rebuilding that intimacy at scale. Our product performs deep research on social followers, enables brands to authentically engage through personalized DMs, and delivers the perfect offer tailored to each customer at exactly the right moment. What once felt impossible, knowing every follower by name and why they care about your brand, is now achievable.
In under 3 months, we're live with 10+ brands, including several 9-figure direct-to-consumer (DTC) companies, and NBA teams to drive substantial revenue and nurture lasting loyalty.
We’re backed by Pear VC (first checks into Doordash, Dropbox, and Gusto), Founders, Inc., and recently invited SignalFire to our investor group. Now, we’re hiring the founding team that will scale Blueberry across the world’s largest brands.
Brands with millions of followers rely on Blueberry to authentically engage their customers at scale. As our Founding Engineer, you’ll be a co-architect of everything we build at Blueberry. You’ll be responsible for shaping the technical foundation of the company: product, platform, and team culture.
You’ll work directly with the founders and Founding Designer to:
Build and scale the core product that enables brands to authentically engage millions of followers.
Make foundational architecture and stack decisions that allow us to move fast today while preparing for global scale tomorrow.
Translate customer needs into elegant, resilient technical systems that balance speed, quality, and reliability.
Set the tone for our engineering culture — one that is high-caliber, collaborative, and deeply product-minded.
You’ll have massive influence over how Blueberry evolves, from the codebase to the customer experience to the engineering org itself.
