Software Engineer, Fraud Prevention


At Olo we develop an online food ordering platform used by many of the country’s largest restaurant chains, reaching millions of consumers. Chances are if you’ve ordered directly from a restaurant brand’s app or website, we’ve made that happen. Mobile ordering and payments is an exciting and active industry full of interesting players and yet still a relatively untapped market ripe for disruption. We’re quite up-front about the technical challenges our business faces. Running a platform with multiple white-labeled front-ends, that maintains real-time connections into thousands of restaurants’ POS systems, and coordinates complex transactions between these and other third parties (such as payment gateways and gift card providers) is not for the faint of heart!

Do you like the thought of fighting cybercrime at scale, watching fraudsters struggle against your defenses, while protecting over a hundred million user accounts?

Fraud is an ongoing concern among restaurant brands, and we aim to make fraud defense a competitive advantage in our product offerings. We’re looking for a software engineer to help fight fraud on behalf of our clients. You’ll be responsible for detecting, fighting, and preventing: credit card fraud, account takeover attacks, gift card enumeration attacks, and distributed botnet attacks of various kinds.

Any engineer may work at Olo’s headquarters in New York City’s Financial District or remotely from anywhere in the U.S. In fact, more than half of our engineering team is remote!

Responsibilities include:

  • Sharpening our credit card fraud prevention service, Shield.
  • Enhancing customer frontends to encourage good security practices.
  • Improving monitoring and alerting for suspicious activity in our applications.
  • Creating automation to respond to fraud reports in an efficient and professional manner.
  • Evaluating and integrating with third party service providers.
  • Building visualizations and reporting tools for our clients.
  • Advising development teams to ensure anti-fraud measures are in place.

This is a full stack engineer position. Your work will span all layers across multiple projects in a large, distributed system. Our tech stack includes C#, F#, Ember, SQL Server, PostgreSQL, Redis, ElasticSearch, Datadog, SumoLogic, Cloudflare, and a number of AWS services including Redshift, SQS, S3 & Kinesis Firehose. We don’t expect candidates to be familiar with all of these technologies, but in this role you will gain experience with most of them.


  • An ability to put yourself in a fraudster’s shoes and think like they do, so you know what we are up against.
  • An ability to work well with others. You will be working in the codebases of many teams. You will need to communicate well and minimize disruption.
  • At least 3 years of professional experience as a full stack software engineer.
  • Proficient in multiple programming languages, frameworks, databases, and OS’s.


  • A background in fraud or security.
  • Machine Learning expertise.
  • Experience working on SaaS products or distributed systems.
  • Experience with PII security frameworks such as NIST 800-122.
  • Experience with any technologies in our technology stack (.NET, AWS, etc.)
