Staff Software Engineer, Guest Lifecycle & Loyalty

The Guest Lifecycle & Loyalty (LILO) team is building what amounts to a world-class marketing agency for every restaurant on Owner — running automatically, at scale, with data-driven optimization that even a great agency could never match. We own the messaging, loyalty, and intelligence that turn first-time guests into repeat guests and long-term regulars across email, SMS, and push, along with the systems that power segmentation, experimentation, and measurement — so restaurants can reliably grow repeat orders and lifetime value.

Our work sits at the intersection of product, data, and deliverability/reliability: we're scaling high-volume communications safely, improving attribution and experimentation rigor, and raising the quality and timeliness of the customer data that drives personalized outreach.

And we're at an inflection point. The foundations — reliable delivery, trustworthy attribution, modern campaign infrastructure — are coming together, and that unlocks the exciting part: making marketing radically more personalized at both the restaurant and the guest level. Picture campaigns that generate themselves from real-world signals, creative that adapts to each restaurant's brand voice, and channel, item, and offer decisions optimized for each individual guest.

Some of that will run on LLMs; much of it, at guest scale, will require classic ML systems we haven't built yet.

- Set the technical direction for the personalization platform — the systems that decide who we reach, when, on which channel, and with what creative, item, and offer — and chart the path from today's foundation toward an increasingly autonomous, agent-assisted future.

- Build the intelligence layer, combining LLM-powered and classic ML approaches to personalize marketing at restaurant and guest scale, where cost and latency mean we can't just reach for a model call every time.

- Own the hard, high-leverage problems that make all of this possible and trustworthy — reliable high-volume sending, an experimentation and measurement engine teams can trust, and the data quality that great personalization depends on.

- Turn one-off campaign work into a durable platform, so launching a new guest journey becomes configuration rather than a bespoke engineering project — creating leverage for the entire team.

- Amplify the engineers around you — set the technical bar, mentor and grow engineers within and beyond LILO, lead design reviews, and leave the people and systems you touch meaningfully better.

- Help shape the roadmap alongside Product, Data, and Marketing, bringing clarity to ambiguous, open-ended problems and helping decide what we take on next.

A track record of owning and driving ambitious, multi-person initiatives that cross team boundaries — from a vague but exciting idea through to measurable, durable impact. (Typically 8+ years of relevant experience.)

You make the engineers around you better — through mentorship, high standards, thoughtful design review, and the patterns and systems you leave behind.

Comfort designing reliable, high-scale services and data pipelines, with good instincts for where to invest in robustness and where to move fast.

You reach for holdouts, incrementality, and measurement to know what's actually working — and you're excited to apply ML and AI to real product problems.

You turn open-ended, aspirational goals into concrete technical bets, and you're energized rather than daunted by problems nobody has solved yet.

You align stakeholders and move decisions across teams without relying on authority.

- The estimated starting base salary range for this role is $220K-$240K depending on level, location and experience, plus a generous pre-IPO equity package
