Description du poste

About Koddex

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.

The Role

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.

What You’ll Do

• 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.

Who You Are

• Rust Proficient: You have professional experience (or a deep portfolio) in Rust and a strong grasp of the borrow checker and memory management.

• Database Native: You are comfortable with PostgreSQL and advanced SQL. You understand indexing strategies and how to avoid performance bottlenecks.

• CS Fundamentals: You have a passion for algorithmic performance and know how to weigh different data structures for specific use cases.

• Self-Starter: You are naturally inquisitive, highly organized, and thrive in an environment where technical excellence is the baseline.

Why Koddex?

• 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.
