Middle Python Developer

Ajax Systems is an international technology company and Europe's largest security systems manufacturer. Ajax offers control panels with its own RTOS (OS Malevich), video surveillance, motion, opening, flood, and fire detectors, outdoor and indoor sirens, a panic button with device control functionality, and automation devices. Ajax Systems possesses numerous proprietary technologies: Jeweller and Wings radio protocols, Fibra wired communication protocol, LISA, SmartDetect, HazeFlow 2 algorithms, JetSparrow technology, and holds 38 patents for inventions, designs, etc.

We are currently looking for a Python Developer to join the development of internal tools for testing OS Malevich. This role does not involve manual or automated testing of the OS itself. It entails creating and maintaining an internal product used to ensure quality and optimize testing processes.

Our ideal candidate has:

• 2+ years of commercial development experience;
• solid knowledge of asyncio (tasks, coroutines, context switching, and their purpose);
• understanding of Python's internal workings ("under the hood") (memory allocation, optimizations, etc.);
• thorough understanding of OOP, design patterns, and best programming practices;
• experience with version control systems (Git);
• basic knowledge of Docker and containerized environments;
• excellent problem-solving skills and analytical thinking with high attention to detail.

Will be a plus:

• understanding of testing frameworks (Pytest, Unittest);
• basic knowledge of OC Unix/Linux;
• knowledge of multiprocessing and sockets;
• good knowledge of SQL and experience with relational databases (e.g., PostgreSQL, SQLite);
• experience with CI/CD tools (Jenkins, Bitbucket, etc.);
• experience with cloud platforms like AWS;
• knowledge of binary serialization (MessagePack, Protobuf, etc.);
• experience with microservice architecture.

Your responsibilities will include:

• developing and implementing new frameworks, services, and technologies to automatically test the system and transform test syntax written by the QA department into constructs for framework execution;
• maintaining and improving existing frameworks, services, and technologies;
• working with CI infrastructure (Jenkins, Bitbucket-pipelines);
• writing high-quality, understandable, commented, and maintainable code with unit test coverage;
• conducting high-quality, well-reasoned code reviews for colleagues.

We offer:

• the opportunity to propose and implement your own ideas that impact the product and production;
• work in a motivated team and a zero-bullshit culture;
• competitive salary;
• medical insurance;
• corporate English classes;
• compensation for professional development;
• the opportunity to participate in the beta testing program for Ajax security systems — receiving and testing new gadgets before their release.
