Summary

This role is designed for a seasoned backend expert with at least 8 years of experience, specifically someone who thrives at the intersection of architecture and growth. While the listing is tagged as "mid-level," the expectations are clearly "Staff" level: you'll be setting a year-long technical strategy for distributed systems and building shared platforms for things like rewards, loyalty, and experimentation. If you have a background in **Python, Kotlin, or AWS** and enjoy acting as a "force-multiplier" for other teams, this is your lane. The compensation is highly competitive, with a base salary reaching up to **$270,000**, plus equity and a 100% subsidized health plan for you and your family. As a **remote-first** company, you’ll have the flexibility to work from anywhere in the U.S. while enjoying unique perks like "Flexible Spending Wallets" for tech and lifestyle expenses and an Employee Stock Purchase Plan (ESPP). **You might be a good fit if you:** * Have a track record of building **highly available distributed systems** (Kubernetes, Spark, MySQL). * Enjoy designing internal APIs and abstractions that other developers use to launch products. * Want to lead high-stakes technical initiatives without needing direct management authority. * Prefer a culture of "honest credit" and transparent, high-quality engineering standards.
