## Description

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.
-   Expertise in writing unit tests using frameworks such as Google Test (GTest) or CppUnit.
-   For SDET positions: demonstrated test automation capability and experience owning quality for delivered features.
-   For PostgreSQL positions: strong hands-on PostgreSQL experience including SQL, PL/pgSQL, indexing, query tuning and schema migration.
-   For the Lead Developer position: demonstrated experience leading a development team, owning technical design decisions and mentoring engineers.

What will give you an edge

-   Knowledge of semiconductor manufacturing operational practices.
-   Knowledge of equipment communication standards and protocols used in manufacturing systems.
-   Experience with manufacturing workflows, process flows and work order management.
-   Familiarity with Python or scripting languages for automation and tooling.
-   Experience with CMake or Makefile-based build systems and cross-platform builds.
-   Experience implementing CI/CD pipelines (e.g. Jenkins).
