Your Job

We are looking for a skilled Senior PHP / Symfony API Developer to join our team and play a key role in shaping and maintaining the backbone of our analytics and core systems. Your expertise in crafting robust, scalable, and secure APIs will drive the development of critical services powering our platform.

To specify

• Architect, develop, and maintain high-performing APIs using PHP and Symfony.
• Enhance and optimise API performance for reliability and speed.
• Implement and uphold security best practices in API development.
• Write clean, maintainable, and well-documented code to ensure longevity and scalability.
• Collaborate with cross-functional teams to deliver quality solutions.

Your profile for this job

• 5+ years in PHP development, with 3+ years focused on building APIs.
• Expertise in RESTful API design and principles.
• Proficiency with version control systems (preferably Git) and experience in CI/CD workflows.

Bonus Skills:

• Familiarity with message queuing systems (RabbitMQ, Apache Kafka).
• Experience designing APIs for analytics or statistical data.
• Strong understanding of database optimisation and query performance tuning.

Your mind set to share our adventure

• You want to make an impact and move things forward collectively. Does hearing phrases like "Yes, but we've been doing it this way for years..." make your hair stand on end? We feel the same way: progress is made by questioning what already exists.

• You solve problems pragmatically and analytically.

• You're looking for a fast-moving environment where your agility will be an asset. The 80-20 (Pareto) principle holds no secrets for you.

• Your ability to listen encourages you to challenge and improve yourself on an ongoing basis.

Our working conditions

• A convivial and flexible working environment, with our telecommuting culture integrated into the company's organization.

• A friendly and small-sized team that you can find in our offices near Lille or in Paris.

• Social gatherings and company events organized throughout the year.
