My 1-month internship at Docaposte Casablanca – discoveries, challenges, and key lessons

I recently completed a one-month internship at Docaposte Casablanca (subsidiary of La Poste / Docaposte group), and it turned out to be a highly formative experience. I was assigned to several teams – development, cybersecurity, testing – which gave me a holistic view of how a digital trust company operates. Here’s a recap of what I worked on, what I discovered, and the lessons I’ll carry forward.

🔍 My assignments

During my internship, I rotated through different teams and missions:

• eSignature / electronic signature
  I explored the development aspects of eSignature services: legal requirements, authentication standards, APIs, and UX considerations for document signing.

• MyGreffe (online service for clerks in France)
  I gained insights into this type of service that supports judicial clerks, involving workflow management, security, compliance, and usability.

• Cybersecurity & GRC (Governance, Risk, Compliance)
  Time spent with the cybersecurity team allowed me to understand how Docaposte handles regulatory compliance (GDPR, eIDAS, etc.), risk management, and internal audits.

• Software testing / Quality assurance
  I discovered the role of testers in the final phase of software design: functional testing, integration testing, bug fixing, performance validation, and preparing a product for release.

• End-to-end software lifecycle
  From conception to delivery: requirements gathering, architecture, coding, peer reviews, testing, documentation, deployment, and maintenance. This global view helped me better understand the complexity behind delivering reliable software.

🛠 Key lessons learned

Some of the most important takeaways:

• Compliance and regulation are central: whether it’s eIDAS for e-signatures or GDPR for data, regulations shape the way services are designed and delivered.
• Security is embedded throughout: from the very first design choices to code, testing, and auditing, cybersecurity isn’t an afterthought.
• Collaboration across teams is essential: developers, testers, and compliance/security specialists each bring critical expertise that must align.
• New roles discovered: QA testers, compliance/GRC teams, and professionals building e-government services – these are less visible but crucial jobs.
• Corporate structure and processes: I learned how roles, hierarchies, documentation, and validation cycles ensure scalability and reliability in large organizations.

💡 How it shaped me

• Stronger technical maturity, seeing how professional-grade software must be built.
• Better understanding of different roles beyond coding – QA, GRC, security.
• Confidence in working in high-stakes environments with strict regulations.
• Inspiration for future projects: integrating security, testing, and compliance from the start.

🔮 Looking ahead

This internship inspired me to explore further:

• Secure architectures, cryptography, and trust-based protocols.
• Quality assurance and testing as a complementary discipline to development.
• Contributing to e-government or public digital services where trust is essential.
• Governance, Risk, and Compliance (GRC) – an area becoming increasingly strategic.
