Our client, a tier one mining and green energy operator, is looking for the next Domain Engineer to join the team for a 12 month contract basis. 
This role will be based in Perth, W.A.

The Domain Engineer is a highly skilled software engineer with a strong mathematical foundation, specializing in optimization algorithms. This role requires a unique blend of expertise in linear programming, operations research, and software development to modify and improve on algorithms and methods used in existing products. With a proven track record of delivering high-performance, scalable solutions, they will collaborate with domain experts, architects, and development teams to assist in improving existing algorithms within the existing product suite.

Responsibilities:
•           Design, develop, and maintain the assignment engine which dynamically allocates tasks to autonomous assets under management of the product suite, leveraging linear programming, combinatorial optimization, and real- time data integration.
•           Collaborate with Architects, Development teams, Verification teams, and other domain experts to translate operational requirements into detailed, high-quality algorithm specifications.
•           Provide expert guidance in solving complex optimization problems, such as minimizing idle time, optimizing routes, and balancing fleet utilization in mining operations.
•           Work with architects to create detailed development work packages for the algorithm improvements, ensuring alignment with system architecture and operational goals.
•           Contribute to the product delivery plan by providing insights into optimization-driven software development timelines and dependencies.
•           Mentor other engineers, sharing expertise in mathematical optimization and software development to accelerate team growth and knowledge sharing.
•           Actively participate in technical discussions, advocating for solutions that balance computational efficiency with practical mining operational needs.

Skills and Behaviour
Professional Skills:
•           Bachelor’s or Higher degree in Mathematics, Applied Mathematics, Operations Research, Computer Science, or a related field—or equivalent industry experience.
•           7 years of software development experience, with at least 3 years focused on optimization algorithms, ideally in autonomous systems or logistics.
•           Deep understanding of linear programming, integer programming, and heuristic optimization techniques.
•           Proficiency in programming languages such as C# with experience implementing mathematical models in production-grade software.
•           Familiarity with real-time systems, microservices, and asynchronous processing to handle dynamic data inputs from mining operations.
•           Demonstrated ability to solve complex, multi-variable problems by collaborating with cross-functional experts.
•           Passion for staying current with advancements in optimization techniques, autonomous systems, and software engineering practices.

Personal Behaviours:
•           Excellent communication skills to articulate complex mathematical concepts and technical solutions to diverse audiences.
•           Strong analytical mindset with a rigorous approach to problem-solving and validation.
•           Collaborative and adaptable, thriving in cross-functional teams under dynamic project conditions.
•           Interpersonal skills to build trust and mentor colleagues effectively.
