Backend Engineer (Rust) - @Koddex

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.

Location: Lille, France (Euratechnologies) 

Work Mode: Full-Time, Hybrid (Up to 3 days remote)
