What do you do as a Senior Back-End Engineer?

As a senior engineer, your duties will include: 

  • Implementing and managing the development process from the Minimum Viable Product (MVP) perspective where you deliver value quickly and iteratively.

  • Devising technical projects that meet specific business rules and quality requirements. Think of: speed, scalability, legibility, and being able to easily maintain code, so that our platform will still function perfectly in 20 years' time. You set the technical example and, together with your team, develop a high-quality codebase.

  • Identifying improvements in the technical area, our workflow, and development cycle, for example by researching new technologies or focus groups. 

  • Taking the lead in projects by, among other things, defining MVPs, providing technical advice, and adjusting when necessary. You ask critical questions during reviews, identify technical risks (e.g. impact on other systems), and monitor backwards compatibility.

  • Mapping out any complex dependencies on products from other teams and then work with these teams to generate independently functioning products. 

  • Guiding colleagues through coaching and code reviews. You actively help your colleagues get better at their work and unlock their potential through smart solutions.

Way of working

  • At Gomibo, we have a flat structure and work in multidisciplinary teams. This means that there is no tiered hierarchy, despite different degrees and areas of work experience. Decisions on topics like architecture are not determined top-down; you take them together with your team.
  • You also work closely with the team's Product Owner. It is up to you to convert the functional requirements into a technical elaboration, which immediately adds value for colleagues while remaining practically feasible.
  • Within Gomibo, we work according to the Gomibo Way of Working. You are an expert at this and help your colleagues grow in this. 

Personal development

As a senior, you can go in any direction in terms of growth. It is possible to deepen your technical knowledge within your team or to take on projects that go beyond the team’s scope. You can be given a broader range of tasks, for example by being responsible for the architecture of one of our systems. You can also progress to a role as Staff Engineer or Engineering manager. A functional role in which you maintain contact with providers or create the tickets for a technical project, for example, is also an option.

Examples of current projects

In addition to these projects, you can also take the lead in teams working on overarching themes such as: APIs, architecture, workflows, learning & development, or giving training courses to further improve our colleagues in terms of content.
