We’ve processed billions of dollars in transactions. We’re trusted by 300+ clients - from Tabby and Tas’heel to Hungerstation - and backed by General Catalyst, Sequoia, and Shorooq. Our $67.5M Series B was just the beginning.

  • Support audit and regulatory assessments by providing technical evidence and security documentation.

• Continuous Improvement

  • Research emerging application security threats, tools, and methodologies.

  • Contribute to security documentation, standards, and training for developers.
    

What we're looking for

• Bachelor’s degree in Cybersecurity, Computer Science, or related field.

• 3–5 years of experience in application security, penetration testing, and vulnerability assessment.

• Hands-on experience with penetration testing, threat modeling, and vulnerability assessment tools.
  

Preferred Qualifications

• Experience in securing fintech, banking, or highly regulated software environments.

• Familiarity with OWASP, ISO 27001, or SOC 2 security frameworks.

• Security certifications like CEH, OSCP, or similar.

• Strong analytical and problem-solving abilities.

• Excellent communication to explain complex security issues clearly.

• Ability to work collaboratively with development and security teams.

NB. While we think the above experience could be important, we’re keen to hear from people that believe they have valuable experience to bring to the role. If you identify with the team and mission, but not all of our requirements, then please still apply!!

Why Join us?

We’re building the financial infrastructure for MENA. Not as a slogan, as a fact.

Since 2019, we’ve become the first regulated Open Banking and Open Finance company operating across the UAE and Saudi Arabia. We’ve processed billions of dollars. We connect millions of accounts. We enable companies like Binance, Careem, and Etisalat to build products that were previously impossible in this region.

Our recent $67.5M Series B from General Catalyst and Sequoia isn’t just validation: it’s fuel. We’re expanding into new markets, launching new products, and setting the pace for what financial innovation looks like in MENA.

We solve hard problems. We move fast. We hold ourselves to a high standard. And we’re looking for people who’ve done this before to help us do it right.

If you’re motivated by building something that lasts, not just something that scales, Lean is where you need to be.

Not only do we offer competitive salaries, private healthcare, and flexible office hours, but we also insist that every member of the team hold a meaningful equity stake in the business to ensure long-term alignment. We'd love you to join us for this journey!

Lean is proud to be an equal opportunity workplace and is an affirmative action employer. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or Veteran status.
