Job post summary

Team Trust and Security

About the role

The Application Security team works to discover and fix security vulnerabilities in Shopify's products through sources such as internal security assessments and Shopify's public Bug Bounty program. The team then develops tooling, static analysis checks, and low-level fixes.

While all under one Application Security team, you will have the opportunity to work in one of three key areas to secure our products. 

Proactive Security - 

  • Static analysis (both figuring out rulesets and deploying the technology to run them at Shopify scale), carefully chosen manual security reviews (for very high value or high risk projects), and deploying organization-wide tooling to help teams prioritize security issues

Bug Bounty - 

  • Shopify runs one of the world's largest bug bounty programs. The Bug Bounty team works on making our program even more awesome through tooling and special events (e.x. tracking which reports we haven't responded to outstanding comments on, better search, implementing process such as always giving a report a severity into the technology itself)

Ecosystem Security - 

  • Many external developers use Shopify's API to build things, and merchants want these integrations to be secure. We're building automated tooling both from integrating existing enterprise solutions  and creating net-new scanners with headless browsers to test apps that are coming into our app store from a black-box perspective.

In your day to day, you’ll be working on things like:

  • Testing applications for security vulnerabilities

  • Evolving the security of Shopify's third-party app ecosystem through automated and manual testing

  • Investigating, summarizing, and actioning reports submitted to our bug bounty program

  • Working side-by-side with hackers in Live Hacking Events

  • Developing static analysis tooling to help developers find and fix security issues

  • Educating developers on the best ways to secure their applications

  • Creating hacking challenges to teach development teams about application security


  • Experience working within or building an application security program for an organization

  • Knowledge of common web application vulnerabilities such as XSS, CSRF, and insecure direct object references

  • Experience testing web applications for security issues OR Experience developing web applications using modern frameworks

  • The ability to educate development teams on web application vulnerabilities and work with the developers to address them

It’d be great if you have:

  • Experience developing or deploying security testing tools

  • Experience with bounty programs such as Shopify's HackerOne program (

  • Experience participating in or organizing Capture the Flag (CTF) competitions
