Flatiron Health

Senior Application Security Engineer

3+ months agoNew York, NY

We're looking for a Senior Application Security Engineer to help us accomplish our mission to improve lives by learning from the experience of every cancer patient. Here's what you need to know about the role, our team and why Flatiron Health is the right next step in your career. 

What You'll Do

In this role, you'll work with the Application Security Team to understand our architectures, read our code, break the apps, and find the problems before the bad guys do (through penetration testing, ethical hacking, code review, design review, etc.). You'll build frameworks, APIs, processes, and whatever else is necessary to keep our web applications secure. In addition, you'll also:

  • Stay on the leading edge of security research and make sure the company responds to new things quickly
  • Build application security champions
  • Teach engineers how to write secure code
  • Own the responsibility of securing our products

Our security team embodies a collaborative, efficient, and flexible working environment. While responsibilities are clearly defined, we share a common purpose and goal: employing all measures to protect against threats to our business, because our technology governs the treatment of millions of cancer patients. For us, application security is way more than just code reviews and penetration testing. It's about complete development workflows, defining a security culture, and advocating for security features (like 2FA) in systems. We are always looking for new ideas and trying to make sure the best ideas rise to the top of the heap. We focus on results; we are often architects, designers and engineers, not just advisors.

Who You Are

You're an Application Security Engineer with 3 years of experience. You're excited by the prospect of rolling up your sleeves to tackle meaningful problems each and every day. You’re a kind, passionate and collaborative problem-solver who seeks and gives candid feedback, and values the chance to make an important impact. 

  • You Have a strong foundation in and in-depth technical knowledge of application security, particularly web application security
  • You possess strong foundational knowledge of the web and the various technologies that tie it together
  • You sympathize with the complexity of being a developer and want to help make writing secure code easier
  • You can read code like a book, and be proficient in writing in a language or two. Python, Go, and/or C#/.NET are preferred but not required
  • You understand security’s role in Agile and DevOps workflows with a desire to continually reduce friction between security and engineers
  • You have a general knowledge of cloud architectures and deployment processes
  • You’re able to deal with the ambiguity associated with working in a fast paced and changing environment; self motivated and results oriented
  • You have excellent interpersonal communication skills

 If this sounds like you, you'll fit right in at Flatiron.
