What knowledge does a reliability engineer need? We can get a glimpse of the company’s recruitment requirements. In the WeChat circle of friends, I often see the job requirements of reliability engineers who are forwarded.

The first is the recruitment of reliability experts for a well-known company in the communications industry. There is no cap on salary. Job requirements: 1. More than 8 years of system reliability project experience; 2. A solid theoretical basis for reliability, proficient in reliability modeling, distribution and prediction, fault detection and health management (PHM), design of experiments (DOE), Accelerated life testing, FMEA/FTA and other practices, with rich experience and results; 3. Proficient in data processing, with the ability to build complex mathematical models with specific big data; 4. Work experience in communications, aerospace systems, and rail transit industries is preferred; 5. Those with machine learning algorithm research and experience are preferred.

The second is the recruitment of reliability engineers for a company in the electronics industry. Responsibility description: Participate in the construction and improvement of reliability engineering system, participate in the establishment of reliability design and test standards; define product reliability requirements and carry out reliability requirements decomposition analysis, identify project reliability risks, and adopt analysis design/testing/simulation, etc. Means to optimize and improve; Responsible for the reliability planning/testing/evaluation of the entire product process, formulating project reliability work plans, and leading implementation; as a representative of project reliability, supporting project material reliability management and control, guiding material selection and application risks Evaluation; Responsible for the formulation of reliability test plans for UAV systems/components/materials, and guide the execution of the tests; analyze failures in reliability tests and give suggestions for improvement; formulate project plans and solve them through self-research or cooperation Product pain points, building platform capabilities. Job requirements: full-time bachelor degree or above, major in reliability or electronics; more than 5 years of reliability work experience, experience in the drone (or automobile) industry is preferred; a solid foundation of reliability theory, proficient in reliability design analysis , Design of Experiments (DOE), accelerated life testing, FMEA and FTA, with rich experience and results; proficient in electronic/electromechanical component performance, principle and design, process reliability improvement methods; proficient in electronic/electromechanical component environment and reliability Relevant standards, test methods, failure mechanism and failure improvement methods, have the ability to trigger failures, and can establish failure physical models; familiar with data processing and analysis; clear thinking, purpose-oriented, strong communication and learning skills, good at cross-departmental communication and collaboration .

It can be seen from these two job advertisements that reliability engineers must possess two types of knowledge. The first type is professional knowledge; the second type is domain knowledge. The so-called professional knowledge is the professional knowledge of reliability engineering, such as the reliability modeling, allocation, and prediction knowledge mentioned in these two job advertisements, FMEA/FTA knowledge, fault prediction and health management (PHM) knowledge, and experimental design (DOE). ), accelerated life test, fault physical model knowledge, data processing knowledge, these are the unique professional knowledge of reliability engineering. The second category is domain knowledge, such as communications, aerospace, rail transit, electronics, electromechanics, drones, and other fields. These are engineering expertise in various fields.

Generally speaking, engineering majors can be divided into two categories. One is the so-called vertical engineering majors, such as electronic engineering, electrical engineering, aerospace engineering, aerospace engineering, transportation engineering, civil engineering, etc. Engineers in these majors need to be proficient in certain Basic knowledge of specific professional fields, and then use this knowledge to carry out product innovation design; the other is the so-called cross-sectional specialty, reliability engineering is a cross-sectional engineering specialty. Reliability engineers need to master the basic knowledge of reliability engineering. When using this knowledge to solve practical problems, they need to explore the professional knowledge in a certain field. This type of exploration is not to master this engineering major, but to achieve understanding Or the degree of in-depth understanding. Therefore, the knowledge structure of vertical professional engineers is “narrow frequency spectrum, deep amplitude”, which means that they only need to cultivate in their own professional fields to become an excellent engineer; while the knowledge structure of reliability engineers is “wide frequency spectrum, even amplitude”. , It is necessary to cultivate deep in the reliability engineering major, but also to explore one or several vertical majors, so that such reliability engineers can be called excellent.

In summary, the knowledge structure of an excellent reliability engineer should be: First, he must master the basic knowledge of the reliability engineering profession, and he must always be aware of the latest developments of the profession, because reliability engineering is a rapidly developing new Discipline; secondly, he has been engaged in specific reliability work in at least one vertical professional field, and can combine the proficient reliability professional knowledge with the field professional knowledge under investigation to complete the specific product reliability technology and management work. If you have the ability to repeat this process across domains, reliability engineers can be called excellent. It is only natural that an excellent reliability engineer gets more salary than engineers of other vertical engineering disciplines, and it is inevitable that an excellent reliability engineer’s salary will not be capped.
