Staff Software Engineer, Data Visibility & Attestation (Security)

  • Toronto, ON, Canada
  • Employees can work remotely
  • Full-time

Company Description

Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

Job Description

Asset management is a core tenet of Information Security, traditionally captured through hardware and software asset management. As the company grows, data increasingly becomes an important asset that requires active tracking and management in order to ensure we are building and maintaining appropriate data protection.

As a Tech Lead on the Privacy Engineering team, you will define the broad direction and future of the Data Visibility/Attestation group, which is focused on building out and continuously improving the accuracy of our data inventory as our systems continue to evolve in number and complexity. You will operate on the critical path of surfacing data risk on all Square products and business units, and will have a direct impact on the success of security and privacy of data at Square. In this role, you will closely work with many teams across Square, including other teams within security, as well as platform engineering, product engineering, data science, and counsel. 

You should expect to:

  • Collaborate with leaders across security, platform, data science, and counsel to translate data visibility requirements into technical solutions

  • Design, develop, and test high-quality services or infrastructure that support long-term data visibility/attestation needs across the organization

  • Set broad direction and vision, influence engineering and business strategy, and establish practices to efficiently and effectively address data security and privacy needs across Square’s engineering ecosystem

  • Provide mentorship and reviews for engineering teams working with data visibility/attestation technologies

  • Work with the engineering manager to oversee the success of the team's projects and deliver quantifiable results


Some qualifications you may have:

  • 8+ years of hands on software engineering experience

  • Excellent software engineering knowledge and the ability to provide technical mentorship and guidance

  • A high bar for writing quality scalable, robust, and testable code

  • Relevant engineering experience in data inventorying and classification to support security and privacy processes at scale

  • Experience collaborating with security and engineering cross-functional leaders 

  • Ability to learn new technologies and languages

  • Ability to cut across new or existing services, infrastructure, or frameworks to achieve security and privacy goals

  • Strong communication skills. You’re adept at understanding complex technical concepts and helping your team make decisions to move forward, as well as communicating those decisions up.

  • Effective remote collaboration skills with distributed teams.


As a bonus, you may have experience or interest in:

  • Developing incident response processes or tooling

  • Developing or maintaining processes to meet data governance needs

  • Building novel visualizations to understand data flow, access control, and risk
