Junior Offensive Security Engineer

About us

Traditional banking has never really given you control over your financial life. Satispay exists to change that: to empower people through finance.

That means making financial services easy and accessible for over 6.5M users. We started with payments, then benefits, investing, cards... and we’re not done. Not even close.

We follow the same logic every time: find a real problem, solve it properly, then look for the next one. The destination? To build the most loved financial platform in the world.

If you own outcomes rather than tasks, stay close to what users need, and refuse to wait for someone else to fix what's broken — you'll find people here who work exactly in the same way. And together, you'll build something worth being proud of.

What you'll be doing

As our Junior Offensive Security Engineer, you'll support our security team in securing our cloud infrastructure, mobile, and web applications.

Here's what that looks like in practice:

• Penetration Testing - Perform penetration testing on mobile (iOS & Android) and web applications, using tools like Frida under senior guidance to bypass controls and analyze runtime behavior.

• Code and Architectural Review - Review source code for logic flaws, collaborate with developers on secure design patterns, and assist in reviewing cloud infrastructure.

• Scripting & Automation - Develop scripts to automate testing tasks, create proof-of-concept exploits, and parse tool results to optimize testing workflows.

• Collaborate on Defense - Work closely with the rest of the Security team to test monitoring capabilities, participate in attack simulations, and improve detection strategies.

• Documentation and Reporting - Write technical reports of findings and document remediation steps for development teams.

Who we're looking for

This role needs someone who is a problem-solver, loves teamwork, and gets things done with high curiosity and readiness for real ownership.

• Strong Foundations - Good knowledge of information security basics, networking, web application architecture, and common web vulnerabilities (e.g., SQL injection, XSS, IDOR, race conditions).

• Hands-on Experience - 0–2 years of experience from internships, university projects, active CTF participation, bug bounties, or personal research.

• Curious Mindset - Driven to figure out how business logic can be bypassed and understand the "why" behind each vulnerability.

• Scripting Skills - Ability to read and write code in at least one scripting language (e.g., Python) for task automation and simple proof-of-concepts.

• Interest in Mobile Security - Strong interest in securing Android and iOS apps, with exposure to Frida or Objection as a great starting point.

• Soft Skills - Clear communication, eagerness to learn, and proven capability of working collaboratively in a team environment.

• Bonus Points - Previous contributions to open-source security tools, published CVEs, cybersecurity certifications (e.g., eJPT, OSCP, PortSwigger), or familiarity with AWS/cloud and standard tools (Burp Suite, Nmap).

Don't worry if you don't tick every box. We believe in the power of different viewpoints and strengths. Your unique perspective is important as we build something special: if you're passionate and can make a difference, we truly encourage you to apply.
