Job description:

We are looking for an AppSec (Application Security) Specialist with experience in Information Security, Application Security, and secure development. If you consider yourself a talented professional in identifying vulnerabilities, reviewing code, and strengthening application security, and are interested in working side-by-side with Engineering teams, proposing and implementing improvements that increase product security, this is your chance! You will be part of the team responsible for ensuring product security from development, reviewing, evaluating, and writing code to prevent vulnerabilities and raise the security level of applications, working collaboratively and remotely.

Responsibilities and duties

  • Evaluate technical vulnerabilities and propose solutions to raise the security of our platform, working in our stack (Ruby, Go, and PHP) and developing security fixes in AWS/Lambda.
  • Quickly evaluate demands in the development queue, reducing the AppSec bottleneck and unlocking Engineering deliveries.
  • Actively propose and implement fixes in code, going beyond just pointing out findings.
  • Conduct threat modeling and apply secure-by-design principles in product initiatives.
  • Create guardrails, tooling, and automations that make the secure path the default path for Engineering teams.
  • Integrate and calibrate security tools in the CI/CD pipeline (SAST, SCA, and secret scanning), maintaining a low level of noise and false positives.

Requirements and qualifications

  • Experience with software or security engineering writing and delivering production code (ideally Ruby and PHP), including automations in AWS/Lambda.
  • Experience with Application Security/Product Security: threat modeling, secure-by-design, and creation of guardrails and tooling.
  • Solid knowledge of CI/CD pipeline security, with calibrated SAST, SCA, and secret scanning.
  • Knowledge of AWS cloud security applied to the product.
  • Desirable certifications in the area of information security.
  • Strong ability to collaborate with Engineering teams, proposing and implementing fixes directly in the code, and not just communicating findings.
  • Ability to communicate in English (written and spoken).

Additional information

What you can expect from us?

  • 100% remote work.
  • Culture of trust, focused on results and with a lot of challenge and learning.
  • Autonomy and protagonism, in an environment full of collaboration and empathy.
  • Culture of feedback and 1:1 with human leadership and without micromanagement.
  • Complete benefits such as: meal/food voucher, assistance for daycare, home office, health, education and culture, gympass, birthday day-off, discounts on therapy and English courses, among other partnerships.
