Software Engineer - Security (London)

Yelp is looking for security engineers to keep us safe and sane as we build out our desktop, mobile, business owner, and administrative websites. It's an opportunity to have tremendous impact and broad scope protecting Yelp's data, our employees, and our millions of users. Additionally, Yelp’s future growth in the transactions space has many security implications, both in traditional application security as well as in privacy controls and fraud and risk analysis. 

As a Security software engineer, you'll be responsible for partnering with different engineering teams at Yelp to help build features, tools, and libraries to enable security by default. You’ll also work to identify and fix vulnerabilities in the products we build, as well as work with external security researchers through our public bug bounty program.

What You Will Do:

  • Develop and deploy authentication and security-related components of Yelp’s website and mobile apps
  • Develop libraries used across multiple Yelp apps for secure communication and data storage
  • Pair with mobile, frontend, and backend teams to architect and develop features in a secure and scalable manner
  • Validate and remediate vulnerabilities reported in our bug bounty

What We Are Looking For:

  • While previous application security experience is a plus, we're looking for strong software generalists first, with an interest in application security
  • Understanding of HTML5, current, and emerging browser security models
  • Understanding of PKI and key management
  • 3-5 years of software engineering experience
  • BS or MS in Computer Science or Engineering
  • Experience with languages like Python, Java, Javascript, Puppet, Objective-C, or Swift


  • Experience with AWS and SoA
  • Experience with securing iOS and Android applications
  • Security research or pen testing experience

What We Offer:

  • Full responsibility for projects from day one, an awesome team, and a dynamic work environment
  • Competitive salary with equity in the company, a pension scheme, and an optional employee stock purchase program
  • Private health insurance, including dental and vision 
  • Flexible working hours and meeting-free Thursdays
  • Regular 2-day Hackathons and weekly learning groups, always with interesting topics
  • Opportunities to participate in events and conferences throughout Europe 
  • Public transportation season ticket loan and £50 per month toward any exercise of your choice
  • Monthly personal development allowance
  • Central location, a fully stocked kitchen, adjustable sitting/standing desks, quarterly offsites, happy hours, and more!
