Overview Are you an experienced Infrastructure and DevOps Engineer who is skilled in optimizing performance and technical excellence? We are seeking two individuals to join our team and play a critical role in our development and expansion. As a Senior Infrastructure and DevOps Engineer, you will be responsible for ensuring optimal performance and stability for our Openmesh platform during its next phase of expansion.
About us For the past 3 years, we have been building a decentralized data infrastructure for crypto and Web 3.0, providing access to reliable and immutable data without a middleman. We believe that access to unedited information is a fundamental right in a free and democratic society. Our infrastructure and technology stack are open-source and governed by an open-source community.
Responsibilities
- Ensuring compatibility and effective integration with third-party services through the development of APIs.

- Implementing best practices and coding standards to elevate our APIs to institutional-grade standards.
- Staying current with industry trends and incorporating advancements into our API strategies.
Qualifications
- Bachelor's degree in Computer Science, Software Engineering, or a related field (advanced degree preferred).
- Proven experience in successful API development and architecture.
- Proficiency in various API integration methods and technologies.
- Strong understanding of scalability principles and strategies in API design.
- Familiarity with performance testing tools and methodologies.
- Solid knowledge of security networks and data protection practices.

- Effective communication skills, both written and verbal, with the ability to collaborate across teams.
About OPEN Data and Infrastructure Day We are hosting OPEN Conference and Hackathon as an annual event to bring together developers, data scientists, entrepreneurs, regulators, and corporations to discuss and educate about the disruptive impact of Web3 compared to traditional internet systems. Our goal is to raise awareness about the need to address the problem of concentrated power over our data and IT technologies. We aim to provide valuable insights into the challenges and opportunities in the next generation of the internet, Web 3.0.
Why is decentralization important and urgent? Trusting centralized systems and handing over control of our future is risky. When someone has access and control over a massive resource, there's a potential for misuse. From the commercial use of our data, we've seen how big Web2 corporations can exploit it. Web 3.0 presents an opportunity and responsibility for us to build better technologies that focus on decentralization and the empowerment of individuals. The OPEN conference is an open platform to challenge ideas and build technologies, infrastructures, and standards across Web3.
