Senior Software Engineer, Guest Lifecycle & Loyalty

What you'll work on:

• Own high-impact lifecycle initiatives end-to-end (from ambiguous goal → design → build → launch → iteration), spanning guest journeys like activation, reactivation, graduation, and loyalty.
• Build reliable messaging and data pipelines that power campaign execution (segmentation, scheduling, send-time optimization) across email/SMS/push at scale.
• Raise the bar on deliverability and compliance (domain warmup, provider policies, Twilio registration, throttling/guardrails), ensuring we can send safely while maximizing reach and performance.

What we need:

• Strong technical leadership and action bias. Proven ability to drive multi-quarter, cross-functional initiatives from problem framing through measurable outcomes.
• AI-leaning builder. Hands-on experience shipping AI-assisted features or platform capabilities (LLMs, embeddings, ranking, or ML-adjacent systems), and a pragmatic approach to evaluation, safety, and iteration.
• Strong end-to-end ownership. Ability to take projects from vague problem statements through design, implementation, and production support.

Pay and benefits:

• The estimated starting base salary range for this role is $190K-220K depending on level, location and experience, plus a generous pre-IPO equity package.
• Benefits include comprehensive health coverage, work from anywhere (remote-first workplace), unlimited PTO - plus extra fun perks!
