Introduction:
We took a closer look at the EMQ HStream team in our last post on the HStream Team: Challenging things are more attractive | EMQ 2021 Global Recruitment Season. If HStream database, as a strategic new product launched by EMQ, carries our imagination and hope for the future real-time data processing of the Internet of Things, then the product that the team is responsible for today has supported EMQ to the present.
This article is about the EMQ X team.
Q: How do you evaluate the EMQ X product?
A: Hello, I’m Li Guowei, product manager of EMQ X. Currently responsible for the design and planning of EMQ X Enterprise edition.
EMQ X is an open source MQTT messaging middleware for the Internet of Things. Its core competitiveness includes the characteristics of one-millionth high concurrency, millisecond low latency, distribution and high availability, etc. It is widely used in global smart home, mobile payment, Internet of vehicles and mobile messaging and other cross-industry fields. It also supports flexible deployment in public cloud, private cloud, physical machine, Docker container and Kubernetes.
EMQ X open source project was founded in 2013. Currently, Github Star ranks first in the number of similar projects in the world, and it is one of the projects with global influence in the field of open source in China.
On the basis of EMQ X open source edition, we have launched enterprise edition to provide more professional business support and services for enterprise customers. The new rule engine in the enterprise version is used for Internet of Things message processing and storage, supporting more industrial protocol access, message encoding and decoding, data persistence and many other enterprise-level functions, which can meet the needs of enterprise customers such as operators, Internet of vehicles and industrial manufacturing industries for higher security and real-time. It has attracted well-known enterprises including China Telecom, SAIC Volkswagen and State Grid.
Up to now, EMQ X has been used in more than 50 countries and regions around the world, deploying more than 10,000 clusters and supporting more than 100 million device access, providing strong support for more than 10,000 enterprise users’ iot services. We also often receive praise from users in the community or some offline activities: some users write EMQ X as standard messaging middleware in the Internet of Things technology popular science books; Some users use EMQ X for research and teaching; Some users use EMQ X to put what they have learned into practice and innovate, which is a hot search on weibo…… All of these make our whole team feel very happy and proud.
With the development of the company’s strategy, EMQ X Enterprise Edition will also be the underlying core product, supporting the company’s internal EMQ X Cloud PaaS service and EMQ X Platform two product lines, with a new look to provide more comprehensive services for the industry and the market.
Our starting point is MQTT messaging access. In the future, we will continue to focus on open source messaging and flow processing software for 5G and the Internet of Things market, combined with the company’s existing edge computing products NanoMQ, Kuiper and cloud streaming database product HStreamDB. Provide edge to cloud access, message exchange and flow processing and analysis one-stop solution.
We are confident to be the world’s first class in this field, and continue to maintain leadership and competitiveness. With the support of the open source community and the efforts of the EMQ X team, our creations and efforts are rapidly moving from technology to products and from products to commercial services.
Q: What’s it like working on the EMQ X team?
A: MY name is Deng Haigui, R&D director of EMQ X Enterprise Edition. I joined EMQ in 2016 and have been working in the R&D team of EMQ X.
EMQ X team is the core product research and development team of EMQ, focusing on EMQ X Internet of Things messaging middleware, leading the development of cutting-edge technologies in the global 5G and Internet of Things messaging market. With the help of the world’s leading distributed Erlang/OTP platform and high concurrency technology architecture, we create the most trusted highly reliable, massive concurrency MQTT iot messaging middleware software.
Here, you can participate in the development of EMQ X with team members in Hangzhou, Stockholm, New Zealand, Japan and community developers all over the world. You can have in-depth contact with the construction and maintenance of ten million level access, massive volume of large-scale Internet of Things projects, and face to face discussion and communication with the world’s top Erlang developers.
In addition to daily development work, we also communicate and cooperate with the Open source community through Slack, GitHub, Zoom and other tools, and regularly hold cross-time zone Demo meetings, online/offline Open Source Open Day communication meetings and other activities.
At EMQ, we don’t want to be programmers who just write code: we love open source and rock ‘n’ roll, they let us see the wider world. With persistent pursuit of technology and products and pure ingenuity, we shoulder the mission of “serving the future industry and society of mankind through world-class open source software products” and have accompanied and witnessed more than 100 iterations of EMQ X.
During the past five years of working in EMQ X team, I feel fulfilled and happy. I have not only improved my professional and technical ability, but also met many excellent developers through EMQ, and witnessed the vigorous development of the company and the Internet of Things. I believe that the EMQ X team will provide you with a wonderful and unforgettable experience in your career, just as I believe that we at EMQ will see an exciting future.

Ivy leaves yu big
Hello everyone, this is Yudai from Japan, a software engineer at EMQ.
I am responsible for developing our main product EMQ X, with Erlang. The team members are from different countries, so every two weeks we discuss and agree on the scope of work that is intended to be done during that period. This helps me working in a remote environment.
Recently I have worked on introducing a new configuration format to our product. We had decided to write our configuration files with HOCON, a superset of JSON and it is well used in Java and Scala. In Erlang, we did not have a parser for HOCON, so we had to make one. Erlang is the best language when you would like to design a concurrent application, but as you know, it is less common compared to other general-purpose programming languages. So our tasks often involve creating libraries rather than just using ones. In this way, we lead the community while trying to create the best MQTT broker in the world.
I am looking forward to seeing you at EMQ.
Dmitrii
Hello, my name is Dmitrii Fedoseev, I work at EMQ Sweden as a software engineer, in the domain of cluster scalability and robustness.
I originally come from Nizhniy Novgorod, Russia, but I am currently living in Stockholm, Sweden. I have worked on quite a few different areas in the past: in physics, telecom, finance and music industry.
I first started programming professionally back in the university, where I had developed software for simulating formation of crystals using GPUs. Using graphical processors for the general purpose computations was a new thing back then, and it was really exciting. That made me realize that working with technologies, that are less mainstream, gives me competitive advantage and allows to explore fresh and exciting ideas. Using a programming language that was so close to maths in nature, was really fascinating, and again, it made programming fun.
I accepted offer from EMQ without hesitation. EMQ’s dedication to the open-source, use of functional languages, and a team of extremely experienced and knowledgeable people from all around the world, was what attracted me. I believe that open-source movement is one of the greatest achievements of humankind, and I am grateful that now I can contribute to it full time.
Here at EMQ I can work on truly challenging problems and put all my skills to use. Our team is full of fantastic people, who come from Sweden, New Zealand, Japan and so on.
So if you enjoy solving challenging problems as much as we all do here, you’re welcomed to join EMQ.
