The way businesses talk to people online is broken. Intercom is fixing it. 🛠️

Intercom is the first to bring messaging products for sales, marketing & customer service to one platform, helping businesses avoid the stiff, spammy status quo and have real conversations that build real connections. Designed to feel like the messaging apps you use every day, Intercom lets you talk to consumers almost anywhere: inside your app, on your website, across social media and via email. In February 2017, Intercom announced it had surpassed $50M in annual recurring revenue, an increase from $1M in ARR just three years prior, making it one of the fastest-growing companies in tech. Today more than 17,000 businesses use Intercom to connect with a billion people worldwide. Intercom has 300 employees between its San Francisco headquarters, Chicago support office, and Dublin R&D office, and has raised $116M in venture funding.

What's the opportunity? 🤔

Our security team is responsible for making sure all our products are designed and implemented to the highest security standards. Keeping our customers' data secure is the most important thing that Intercom does. We're looking for an experienced engineer to join our team.  Unlike most companies, we design and build our product entirely in Dublin, so you will be uniquely positioned to own and drive security policies and technologies across all parts of Intercom. Find out more about our engineering culture here. You will get to work directly with our product and infrastructure engineering teams on an interesting mix of application and infrastructure security projects. You will also build and own tools, services and infrastructure used across the company.

What will I be doing? 🚀

You will get to work directly with our product and infrastructure engineering teams, you will also build and own tools, services and infrastructure used across the company.

  • Perform technical security assessments on web applications, mobile clients, and architecture designs
  • Maintain and create secure development practices and programs for our growing engineering teams
  • Communicate security risks to engineering teams through training and technical demonstration of vulnerabilities and secure design patterns for security topics
  • Conduct security code reviews, and architectural reviews

  • building a centralised, 2-factor authentication system to manage access to all internal Intercom systems

  • helping us build a better corporate and production infrastructure

What skills do I need? 📖

You need to be an experienced security engineer, preferably a generalist or a specialist with an interest in all aspects of security. You should prefer automating work over manual processes - we love automation and would love you to build your own tools for automating processes.

  • Practical experience and proficiency with a high level programming language (e.g. Ruby, Python, Perl) -  this skill is essential for you to be able to create tools and work with product engineers on the existing body of code
  • Solid understanding of web application architecture - Intercom is a web app, so you need to know how to secure web apps
  • Solid understanding of threat modelling, web security vulnerabilities as well as their mitigation

Bonus skills & attributes 🙌
