Job summary

We are seeking highly skilled and motivated Software Engineers with strong expertise in C++ and Object-Oriented Programming, with hands-on experience developing and enhancing complex systems. The role is responsible for designing, developing and maintaining high-performance, reliable software that supports manufacturing operations on the ATP MES platform. The SDET positions combine development and test engineering responsibility; the PostgreSQL positions focus on the data layer of ATP MES for Engineering; the Lead Developer position additionally owns technical direction and mentoring for the ATP MES development team.

What you will do

• Design, develop and maintain moderate to highly complex applications using C++.

• Develop, enhance and debug software modules and components.

• Apply strong OOP principles — encapsulation, inheritance, polymorphism and abstraction — to build maintainable and scalable systems.

• Design and implement concurrent, multi-threaded C++ software for real-time or high-throughput systems.

• Contribute to improving existing modules and reusable internal frameworks and libraries.

• Provide technical guidance and mentorship to junior team members.

• Participate in code reviews and provide constructive feedback to peers.

• Develop and maintain unit and integration tests; contribute to and maintain CI pipelines.

• Work with product owners to understand requirements, break down complex problems into manageable tasks and deliver solutions.

• For SDET positions: design, automate and maintain functional, integration and regression test suites alongside feature development, and own the quality of delivered features end to end.

• For PostgreSQL positions: design, implement and tune the PostgreSQL data layer — schema design, queries, stored procedures, migrations and performance optimisation — supporting ATP MES for Engineering.

What you need

• 5+ years of professional C++ software development experience.
• Strong mastery of Object-Oriented Programming with hands-on application of design patterns (Factory, Observer, Strategy, Singleton, Command) and SOLID principles.
• Solid understanding of multi-threading and concurrent programming in C++ with synchronisation primitives (mutexes, semaphores, condition variables).
• Experience developing or integrating with MES or similar large-scale systems.
• Proficiency in STL, Boost libraries and modern C++ (C++11/14/17/20) features.
• Familiarity with thread and memory management concepts and best-known methods; experience with performance profiling and optimisation.
