About the role:

Joining our Booking team means joining the most product oriented team at bsport. You’ll need to demonstrate strong engineering skills, but also a user centric approach of building product, a true sensibility about User Experience and above all that a capacity to work efficiently in a product team. The scope of the team represents more than 60% of the traffic and encapsultates:

• Managing classes, waiting lists, teacher subsitutions, late cancellations etc…

• Managing 1-1 appointments, resource availabilities, calendar display etc…

• Managing our pass and credits system to create bookings

• Integrating and maintaining communication with third-party aggregators (ie softwares offering bsport's classes on their own platforms)

• Evolving our Access Control solutions for self service gyms

What will be your impact:

As a Senior Full-Stack Software Engineer, you will:

• Lead the design of your solutions collaborating with Product and Design, handling constraints (high-volume data, by client data segregation, delivery timeline…) and ensure a balance between immediate product requirements, technical feasibility, and long-term scalability.

• Deliver robust, efficient, and maintainable code using AI processes. Participate in evolving our best practices for code reviews, testing, and continuous integration & delivery.

• Provide technical leadership and share knowledge with less experienced engineers and foster a culture of continuous learning, collaboration, and innovation.

• Collaborate closely with Customer teams to understand clients issues and solve them in a timely manner. Monitor and improve our alerting system to anticipate issues as early as possible.

• Solve production incidents, analyse those afterwards, redact clear documents to share internally and externally, and drive actions to continuously learn and improve on those.

• Participate in our cross-team “chapters”, providing innovative solutions and improvements to our frontend or backend stacks, advocating for best practices.

You would be great fit if you have:

You have substantial experience Python (Django is a plus)

• You are comfortable on challenging a implementation from the data model diagrams to the networking

• You have experience working at scale, serving dozen of millions of users

• You are, of course, professionally proficient in English

• You are not afraid of taking ownership to build exceptional products, including on design and product decision.

• You love domain-driven development, and understands interface purity has its limit.

• You want to lead across boundaries, and scale your impact to the organisation

• You understand both how powerful and how dangerous AI-assisted workflows can be, and want to redefine the barriers of what is doable

Diversity is one of our most valuable assets, and we are committed to fostering an inclusive environment where everyone can contribute their best work. We welcome applicants from all backgrounds, identities, and experiences to help us build a more inclusive, equitable team.

If you’re excited about this role but don’t meet every qualification, we encourage you to apply-curiosity, adaptability, and a willingness to learn are just as important to us as specific skills.
