About The Role

We are looking for a Mobile Security Technician to join our Cyber Security Team, which provides intelligence on hacking of Sun King devices to strengthen and expand the digital and financial inclusion of our customers.

As an ethical hacker, your principal mission will be to identify security loopholes in various vendor smartphones and advise on security considerations. You will test Sun King devices for security flaws, particularly mobile phones, conduct hardware vulnerability reviews of smartphones, IoT and automotive devices, develop custom Proof-of-Concept code, and carry out internal penetration testing across products.

What you will be expected to do:

  • Conduct offensive security assessments of hardware, firmware, embedded operating systems, and payment stacks on Sun King mobile devices.
  • Reverse engineer firmware and perform static and dynamic reviews to uncover security weaknesses.
  • Detect and exploit vulnerabilities in embedded systems, bootloaders, MDMs, Android kernel components, secure boot implementations, and cryptographic mechanisms.
  • Develop and execute proof-of-concept attacks to demonstrate exploitability and business impact.
  • Work with product, hardware, and software engineering teams to define secure development practices and strengthen product resilience.
  • Contribute to threat modeling and architecture reviews for new products and features.
  • Keep current with emerging vulnerabilities, tools, and offensive research relevant to smartphone financing ecosystems.

You might be a strong candidate if you have:

  • Solid knowledge of Android security, Mobile Device Management, IoT device architectures, and hardware security testing.
  • Strong familiarity with hardware exploitation techniques (e.g., JTAG/SWD/UART debugging, side-channel techniques, fault injection).
  • Hands-on experience with Flash 64, Pandora, Easy JTag, Chimera, CM2, and similar tools.
  • Proficiency in reverse engineering tools such as Ghidra, IDA Pro, Binary Ninja, and debugging tools like JTAGulator, OpenOCD, or Bus Pirate.
  • Experience reviewing and modifying firmware images (binwalk, Firmadyne, QEMU).
  • Familiarity with secure boot, TPM/TEE, flash encryption, and other embedded security technologies.
  • Programming and scripting capability in Python, C/C++, Bash, or similar languages.
  • Knowledge of common vulnerability classes (e.g., memory corruption, design flaws, insecure update mechanisms).
  • Exposure to payment/fintech device security and secure device provisioning environments.

What Sun King offers

  • Professional growth in a dynamic, rapidly expanding, high-social-impact industry
  • An open-minded, collaborative culture made up of enthusiastic colleagues who are driven by the challenge of innovation towards profound impact on people and the planet.
  • A truly multicultural experience: you will have the chance to work with and learn from people from different geographies, nationalities, and backgrounds.
  • Structured, tailored learning and development programs that help you become a better leader, manager, and professional through the Sun Center for Leadership.

We place great importance on sustaining a diverse, inclusive work environment.

We believe that innovation and understanding comes from diversity on every spectrum. We work to make sure every Sun King team member knows that they belong, knowing that sustaining an inclusive workplace requires conscious effort and is a continuous journey, not an end-state.

Sun King recruits, employs, trains, compensates and promotes people based on their experience, skills, effort, and results. We explicitly prohibit discrimination on the basis of race, religion, caste, national origin, color, gender, marital status, family structure, sexual orientation, HIV/AIDS status, or disability.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
