We believe the economy is better when everyone has access. When everyone has room to grow. No one should be left out because the cost is too great or the technology too complex. We started with a little white credit card reader but haven't stopped there. We're empowering the independent electrician to send invoices, setting up the favorite food truck with a delivery option, helping the ice cream shop pay its employees, and giving the burgeoning coffee chain capital for a second, third, and fourth location. We're here to help sellers of all sizes start, run, and grow their business-and helping them grow their business is good business for everyone.
Our mobile security team works to prevent security and fraud incidents from occurring on Square's mobile applications, and to enable new payments products with both security- and compliance-driven functionality. We build mobile and backend systems that detect and respond to attempted theft of sensitive data, and we surface the technical indicators we collect to internal systems that protect the Square ecosystem from fraudsters. We're part software developer, part security researcher, and part data scientist, and we take pride in working in multiple technical domains to ship secure products.
We're looking for exceptional engineers to own a security product that enables Square to build products no one else has built.
* Develop and deploy creative detections for mobile security threats for Android and iOS
* Utilize software protection technologies including obfuscation, tamper detection, and whitebox cryptography
* Research and respond to changes in mobile platforms, threats, and attacks in the wild
* Analyze device telemetry data to detect attacks and identify anomalies
* Collaborate with many teams and functions across Square to make technical, design, strategy and product decisions
* Provide guidance and mentorship for other engineers on the team
* Help set strategic direction for security engineering at Square
* Substantial demonstrated experience making mobile platforms more secure either through vulnerability research or deployment of new defenses
* Fluency in C, comfort working with Java and/or ObjC, and experience and interest in shipping critical production code
* Interest in working across multiple technical domains, including backend microservices and iOS/Android clients
* A passion for using security engineering as an enabler for product teams
At Square, our purpose is to empower - within and outside of our walls. In order to build the best tools for the businesses and customers we support all over the world, we have to start at home with a workforce as diverse and empowered as our sellers. To this end, we take great care to evaluate all employees and job applicants equally, based on merit, competence, and qualifications. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, disability status, or any other characteristic protected by law. We encourage candidates from all backgrounds to apply and always consider qualified applicants with arrest and conviction records, in accordance with the San Francisco Fair Chance Ordinance. Applicants in need of special assistance or accommodation during the interview process or in accessing our website may contact us by sending an email to assistance(at)squareup.com.
