Engineering Manager, Data Security

  • Full-time

Company Description

Since we first opened our doors in 2009, the world of commerce has evolved immensely – and so has Square. After enabling anyone to take a payment and never miss a sale, we saw sellers stymied by disparate, outmoded products and tools that wouldn’t work together. So we expanded into software and started building integrated, omnichannel solutions – to help sellers sell online, manage inventory, run a busy kitchen, book appointments, engage loyal buyers, and hire and pay staff. And across it all, we’ve embedded financial services tools at the point of sale, so merchants can access a business loan and manage their cash flow all in one place.

Today, we’re a partner to sellers of all sizes – large, enterprise-scale businesses with complex commerce operations, sellers just starting out, as well as merchants who began selling with Square and have grown larger over time. As our sellers scale, so do our solutions. We all grow together.

There is a massive opportunity in front of us. We’re building a business that is big, meaningful, and lasting. And we are helping sellers around the world do the same.

Job Description

Data Security is core to Square’s success. Square strives to make the basics of running a business easy for our sellers so that they can instead focus on building and growing their business. The Data Security Engineering team similarly aims to make it easy for our engineering teams to protect sensitive data throughout its lifecycle so that Square can ship remarkable products. We achieve these goals through developing data security education and policies, preventative guardrails, and secure, convenient tooling.

  • Develop the data security strategy to enable engineers across Square to ship secure products and features 

  • Build an outstanding team of  remarkable talent and invest in their careers through ongoing coaching and development

  • Use technical expertise to cultivate pragmatic engineering decision-making and sustain high engineering standards on the team

  • Develop efficient processes to ensure the engineering team is operating with high velocity, ownership, and self-accountability

We value Engineering Managers who: 

  • Lead with a people-first approach, can facilitate a conversation rather than dictate it, and are empathetic to divergent viewpoints

  • Have at least 2 years of experience leading teams of engineers, in both a technical and people management capacity

  • Have at least 2 years of hands-on software engineering experience

  • Build strong relationships with their counterparts, including other engineering managers, product managers, and security partners
