Job Description:

Koddex is building the next generation of Data Operations (DataOps). We provide a specialized SaaS platform that streamlines how organizations manage structured data, enabling teams to activate and use that data in real-time. We aren't just a data store; we are the infrastructure that makes data actionable. We are looking for a curious, high-ownership Backend Engineer to join our core team. You will be responsible for designing and scaling our data engine using Rust. This role isn't about building simple CRUD APIs; you will be solving non-trivial problems involving data structure, algorithmic complexity, and high-performance database interactions.

Job Responsibility:

Architect with Rust: Develop robust, memory-safe, and highly concurrent services
Optimize Data Performance: Write and refine complex database queries where efficiency is critical to the user experience
Solve Algorithmic Challenges: Apply your knowledge of Big O notation and complexity to optimize data processing pipelines
Collaborate in Agile: Work within a structured yet fast-paced environment that prioritizes clean code, thorough testing, and rapid iteration

Requirements:

Professional experience (or a deep portfolio) in Rust and a strong grasp of the borrow checker and memory management
Comfortable with PostgreSQL and advanced SQL
Understanding of indexing strategies and how to avoid performance bottlenecks
Passion for algorithmic performance and know how to weigh different data structures for specific use cases
Naturally inquisitive, highly organized, and thrive in an environment where technical excellence is the baseline

What we offer:

Tech-First Culture: Join a team that values technical depth and elegant solutions over 'quick fixes'
Hybrid Flexibility: Work from our vibrant office in Euratechnologies (Lille’s tech hub) with the flexibility to work remotely up to 3 days a week
Impact: As an early hire, you will have a direct influence on our architecture and the future of the product
Great Vibes: We maintain a fun, supportive, and highly collaborative workspace
