Staff Application Security Engineer

We created Upside to transform brick‑and‑mortar commerce. Our technology uses the sophistication of online retail—profit measurement, attribution, and incrementality—to provide users with more value on their everyday purchases and brick‑and‑mortar businesses with new, profitable customers. We’ve helped millions of users earn 2 to 3 times more cashback than any other product, and hundreds of thousands of brick‑and‑mortar businesses earn measurable profit.
