Software Engineer

Software Engineer – Python/Rust Hamburg (Hybrid) €70,000 - €110,000 + Benefits
Our client is a market leader in production planning & scheduling SaaS solutions. The successful candidate will be highly skilled in Python, Rust, and have experience in building performance critical high-load backend services.
Being a Senior Backend Engineer, you’ll work in the AI & Optimization Team with teammates that “know their stuff”.
You will be working at the heart of the application. Our client is rapidly changing and evolving the core logics and algorithms to achieve everlasting positive impact on the performance of customer supply chains. The backend is a hybrid combination of simulation and optimization components. You will be working on extending the simulation engine, performance improvements, modeling new constraints and more.
You will be facing complex requirements in a complex domain - which is inherently not mathematically end-to-end solvable. So, if you are keen to find scalable, generic solutions for complex mathematical problems - you have found your match!
What you will be doing

• Extend our simulation engine (mainly constraint propagation & complex state searches) partially in Rust, partially in Python
• Interface design and evaluation of simulation and optimization components for web services & APIs
• Benchmark performance of critical backend services
• Setup APIs and services to integrate our optimization and simulation backend with the rest of the application
• Development of solvers using different technologies (mostly hybrid systems between heuristics, constraint programming and meta-heuristics)
• Test suite maintenance and extension for simulation and optimization components

Requirements

• Extensive knowledge and expertise in coding in Python
• Extensive knowledge and expertise in coding in Rust (3 years or more experience)
• Experience in building performance critical high-load backend services
• Experience building long-term sustainable software end-to-end
• Capability to work independently on subtopics
• Capability to work in large and complex codebases
