Security & Compliance Engineer in Marseille

Buy Co digitalizes and simplifies container shipping operations with a motto: “Shipping made easy!” Most of the things around you (your phone, your clothes, your coffee) crossed an ocean in a shipping container.

Behind each of those containers, a company has to book space on a ship, coordinate carriers, freight forwarders and customs agents, and keep track of dozens of documents, often still by email, phone and spreadsheet.

That's where we come in.

• Our collaborative Saa S platform
• book, organize and track their shipments from start to finish
• work smoothly with their own teams and all their partners
• get clear visibility on where their goods and documents are
• use their data to make their supply chain more efficient and more sustainable

Our mission: bring an industry that still relies heavily on manual work into the digital age, with a platform people actually enjoy using.

Buy Co was founded in 2015 by a team combining deep maritime expertise and a strong tech background.

Today, we're around 50 people.

Solidly funded, we have ambitious plans: new features on the platform (like our CO2NTROL project, which helps clients measure and reduce the CO2 emissions of their shipments) and faster growth, with new clients, especially abroad.

Want to work with energetic, experienced people who care about results? Join us and help change the way goods move around the world!

Job Description

We are recruiting a

Security & Compliance Engineer .

As Buy Co grows, especially abroad, security and compliance have become key expectations from our customers.

Buy Co is ISO 27001 certified, SOC 2 certification is around the corner, and new regulations such as the EU AI Act are coming.

To support this ambition, we are looking for someone who combines strong hands‑on security expertise, a solid tech culture and a taste for governance and compliance.

The role is a 50/50 split between security and compliance, with a stronger focus on security expertise.

On the compliance side, you will be supported by our compliance automation platform, Drata.

You will play a key role in making Buy Co's platform more secure every day and in keeping our certifications and policies alive, while spreading a strong security culture across the company.

• You will report directly to Joffrey, Head of Platform, and join a team with:
• Saad, Platform Engineer
• Ludwig, Senior Cloud Engineer
• César, Security & Compliance Administrator apprentice and work closely with:
• our Software Engineers

• the Data team but also

• all Buy Co teams, as security and compliance are everyone's business
• our external partners: pentesters, security vendors and service providers, and customers' security teams

What you will do on a daily basis

• Core tasks
• Secure the Buy Co platform by applying and promoting best practices across our infrastructure: AWS, Azure, data tools and Kubernetes.
• Act as Buy Co's pentest referent: work with pentesters, understand their findings and recommendations, and drive remediation with the engineering teams.
• Prioritize security topics based on risks, so the main risks are always covered.
• Spread a strong security culture: explain security choices in simple words and bring teams on board.
• Security operations (run & build)
• Monitor, maintain and improve Buy Co's security stack: check alerts every day, triage and categorize them, and create tickets for the right teams.
• Improve our security tooling over time, and contribute to the choice of new tools and service providers.
• Manage access across the company: onboarding, offboarding and access levels.
• Compliance & governance
• Maintain and improve our ISO 27001 certification and our SOC 2 certification (to obtain or maintain, depending on your start date), with the support of Drata.
• Write, update and improve our security policies, rules and processes.
• Prepare internal audits (at least once a year, ideally twice).
• Handle GDPR topics and their international equivalents (e. g. LATAM, Australia), and prepare Buy Co for the EU AI Act.
• Answer our customers' security questionnaires.
• Your path at Buy Co
• 4 months after your arrival: you have a good grasp of the whole Buy Co platform: our infrastructure, Disaster Recovery Plan, SLAs and ISO 27001 framework.

You can answer a customer's security questionnaire on your own.

• 8 months after your arrival: you have run a gap analysis between where we are and where we want to be, and built Buy Co's security roadmap.

The hot topics (platform, development, tools, processes) are identified to get and stay compliant.

• 1 year after your arrival: your impact on security and compliance is concrete and visible.

Our certifications are ready for renewal, internal audits show no non-conformities, and Buy Co has clear governance on data, AI and GDPR risks.

• Preferred Experience
• You have solid experience in cybersecurity and can work autonomously from day one on security topics.
• You speak English and French, and are comfortable working with vendors and customers in English.
• You have a strong tech background: you understand infrastructure and software engineering fundamentals, and you can talk with developers in their own language.
• You have hands‑on experience with public Cloud (AWS preferred) and Kubernetes.
• You have already taken part in a certification process (ISO 27001, SOC 2 or any other). You don't need to be a compliance expert: you are eager to grow on this side.
• You know how to prioritize based on risk: you know nothing is infallible, and you focus on what matters most.
• You anticipate problems instead of waiting for them.
• You are a good teacher and tenacious: you can explain tricky security topics in simple words and bring people on board.
• You are curious and keep up with new topics, such as AI and its security challenges.

Your profile will be if

• You have worked with Wiz or another Cloud security platform, and with Drata or another compliance automation tool.
• You have experience with Identity and Access Management, ideally Keycloak.
• You know GDPR well and have followed the EU AI Act closely.
• You have worked in a B2B Saa S company.
