Software Engineer, Identity Verification and Activation

  • San Francisco, CA
  • Full-time

Company Description

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.

Job Description

Square empowers sellers and third-party developers to process omnichannel payments globally. Help build the platform that enables Square to do this with ease.

Operating in the regulated financial space, we are required to verify businesses and individual’s real-world identity when onboarding into Square’s ecosystem. We do this via our Verification and Activation Platform which answers critical questions such as: “Are you who you say you are” and “Should we be doing business with you”. As the entry point into our Managed Payments Platform, we help internal and external developers solve these challenges for their customers globally. Our team owns the backend infrastructure that enables businesses to onboard with Square quickly, allowing sellers to accept payments in just a few minutes. Our systems are the first line of defense against bad actors trying to sign up onto Square’s platform illegitimately

Why is this team important to Square?

  • Instrumental in unlocking critical features for our customers (and their customers) such as payment acceptance and settlement, activation of Square card and access to credit products

  • New customers onboarding into Square who get access to financial products like Point-of-Sale, Cash, Caviar, Capital, as well as third-parties like TheCut and Traveljoy are identified, verified and activated through our platform

  • Our success in building a global IDV platform is critical for Square’s continued success in existing markets, as well as expansion to new markets

Hard Problems

  • Verifying real-world identity: Security and privacy for our customers are extremely important to us. We are constantly pushing the boundaries to give our product teams the room to create frictionless user experiences, and our legal & compliance teams the tools they need to be more effective

  • Scale: Our platform has to serve not just the whole company and our customers, but also third-party developers and their customers

  • International: With the efficacy of identity verification mechanisms varying wildly from market to market and regions, this team investigates and incorporates new technologies to automate customer verification, helping product teams onboard new sellers of all sizes across the globe in just a few minutes

  • Creative Solution: We investigate new technologies to constantly improve our identification algorithms, leveraging data and machine learning as tools for identification 

You will:

  • Help build our Verification and Activation platform and APIs, a key strategic asset used by the company as well as external developers

  • Design and implement high-volume, low-latency, distributed systems

  • Abstract, design and develop coherent service APIs for Square products and external developers to build upon

  • Build systems that manage customer’s sensitive data and hold Square to the highest standards for security and compliance

  • Work cross-functionally with our product, business, and finance teams to develop Square’s global payments strategy

  • Design fault tolerant systems so the team can be brave, move fast, and break things, without ever showing a negative impact to customers


You have:

  • BA/BS degree or equivalent experience (4+ years preferred)

  • Expertise in any object-oriented paradigm / language

  • Curiosity and desire in designing and creating highly available, compliant, global real-world identity verification and activation systems

  • Interest in changing the payments landscape in the US and globally

  • End to end application experience (preferred)

  • REST API development experience (preferred)
