Golang Job Details

Our Mission:

Are you a motivated experienced person, used to working in an international multi-cultural environment, who really wants to make a difference in the open-source world? Are you looking for a role where you can really make an impact?

At Open-Xchange, we decided to leave dead-end jobs where you don't make an impact and offer passionate experts the opportunity to be part of an international team that connects the world and millions of people by developing and delivering open-source technologies.

We believe it’s crucial to work in an environment where people feel valued, are energized by their work and deliver added value – not only to colleagues, but also to everyone using our products.

So this is what you get at Open-Xchange:

  • You’ll learn from experts and increase proficiency by sharing your knowledge and profiting from theirs.
  • You’ll work with colleagues from all over the world, so connecting people is not only our vision, it’s the way we work.
  • You'll use open-source technology and play your part in the fight against big, dominant companies to keep the internet open.
  • You'll work in a company with the whole tech stack.

Does that sound like the working environment for you? If so, please get in touch and we can start the discussion.

Many experts feel trapped in their job and don't think they can make a difference; however, that’s simply not true – everyone can make a difference!

Be ready to shape your personal future, and the future of millions of people.

Team info:

You’ll be part of a brand-new team that has responsibility for developing and maintaining the OX Cloud MTA platform. You’ll be working closely with the Cloud Operations team, but also across our in-house functional teams, including Support and Engineering Services.
You’ll also be working in a large-scale operational environment, applying architecture and technology choices that enable a highly reliable, stable, and secure MTA platform. As part of this, you’ll be working on a process of continuous improvement to steadily improve the platform with minimum impact on the mail service.

Our tech stack:

  • Common protocols/standards SMTP, SPF, DKIM, DMARC, DANE

  • Coding languages include Golang, Python or Ruby

Your new job:

  • You’ll own and maintain the strategic OX Cloud MTA project and together with your colleagues you will build, test, and maintain the code and policies present in the OX MTA solution.
  • You’ll have responsibility for designing and implementing processes to handle and avoid abuse on the OX Cloud Platforms – we are looking at stepping up our capabilities around abuse detection and response.
  • You'll help deliver ever-increasing workload efficiencies through increased systems automation and monitoring.
  • You'll work across departments to advise and guide product delivery in order to achieve team goals, as well as prioritized projects.
  • You'll be responsible for handling the IP warm up process and the RBL delisting process.
  • You'll develop and share knowledge of abuse analysis/investigation tools and techniques with the rest of the team.

Your background:

  • You have a strong background as a delivery engineer, anti-abuse engineer or perhaps systems engineer with focus on security.
  • You have a good overview of the MTA and AVAS vendor-space and you enjoy finding new ways to automate your daily workload eg. delivery monitoring or abuse handling
  • You have a passion for trouble shooting and you are driven to find answers to the latest security or deliverability challenges.
  • You are driven to continually conceive and test new ways to detect and prevent abuse of our platform.
  • You are used to keeping up to date with upcoming standards and you are not afraid of reading up on the occasional RFCs.
  • You can effectively communicate in English verbally and in writing across all levels.
  • You are a team player and you love to share your knowledge and learn from others.
  • You are motivated and creative and want to connect the world through Open Source technology.

This is what you get at Open-Xchange:

  • The possibility to work full or part time wherever you want in accordance with your needs.
  • Flexible working hours that allow you to successfully combine your home and family responsibilities with work.
  • Stay up to date with latest tech, by working on modern cloud software in an international team.
  • Sharing thoughts is part of our DNA so expect Workshops and Team Events.
