Our customers are large manufacturers for whom planning is mission-critical, and every customer's production looks a little different. We're growing, and we need more strong engineers in the team that turns that complexity into working solutions. About the role You'll join our AI & Optimization team. Despite the name, this is not a machine learning role. The team builds the automation and simulation engine at the core of our product: the logic that decides how plans work for each customer. You'll take feedback from customers and planners and turn it into solutions that work in real production environments. We work mainly in Python. For the most performance-critical parts, we may introduce a compiled language such as Rust or Go in the future, depending on what we need. The team The team is growing. Alongside a newly appointed team lead and a business analyst who works closely with our customers, we're now expanding the team with new engineers. That means you'll have a real chance to help shape how the team works from the start. You'll also work closely with our Applications team, which builds the features and interfaces for all customers. We work in a flat structure: engineers take initiative, create their own first drafts and own their solutions end to end. What you'll do * Extend our automation and simulation engine in Python * Design and implement planning and scheduling logic for customer-specific needs, together with the team * Turn customer and planner feedback into working solutions * Design the interfaces between our engine, web services and APIs * Benchmark and improve the performance of critical backend services * Help shape and refine our own DSL (domain-specific language) for our customer-aware automation and optimization engine * Maintain and extend the test suites for our engine
