Senior Application Security (AppSec) Engineer

Amsterdam, Netherlands | Engineering | Full-time

We’re looking for a senior-level engineer to lead software security initiatives across multiple product engineering teams. You’ll guide, oversee, and collaborate closely with team leads on key projects, while taking full ownership over the code security of our products.

Our ideal candidate is highly versatile and eager to influence decisions of all sorts, from small features to large-scale implementations. You think about coding as craftsmanship. You  are constantly on guard against bad actors, and you possess a healthy degree of paranoia.

At Lemonade, we only use Macs, we’re obsessed with productivity, and we’re passionate about automation, AI, and bots. The Security team loves finding creative and ingenious ways to protect our customers and the company. If this sounds good, we’d love to hear from you.

  • 5 years of relevant experience in AppSec research
  • Must have a mastery of the software development life cycle (SDLC), and proficiency in a range of programming languages, preferably TypeScript, JS, Python, and Ruby
  • Solid understanding of common attack vectors, vulnerabilities, and mitigations
  • Ample experience in high-level code auditing of backend systems
  • Significant experience fixing security vulnerabilities in live web applications
  • Adept at analyzing risks of identified vulnerabilities
  • Proven track record of managing many post-mortem analyses
  • Strong familiarity with cloud environments, preferably AWS
  • Familiarity with a wide range of database types and architectures is a plus
