About The Position

In this role, you will build the automations that run daily for our clients, from the initial prototype to operational deployment. You will construct integrations between systems not designed for each other, such as ERP, specialized applications, learning platforms, databases, and mailboxes. You will access systems lacking a usable interface by developing custom connectors, translation layers for legacy systems, or using RPA as a fallback. This is the core of your work, not a secondary task. Recent projects include integrating two specialized systems for a regional energy provider, the quote request process in an ERP for an internationally active trading company, and the course management system for a training provider. You will automate entire workflows, not just individual steps, including inter-departmental handoffs. Tools used include n8n, custom services, and existing client systems. You will own topics end-to-end: analyzing, building, testing, deploying, and supporting them in operation. You will communicate directly with the people whose work you are automating – including the business department, IT, and sometimes management. You will utilize AI as a tool, both in the development process (e.g., Claude Code, sub-agents, custom workflows) and within the product itself, such as for processing emails, PDFs, and documents. You will contribute your perspective to architectural and technology decisions, which are made through discussion rather than directives.

Requirements

Approximately three to six years of professional experience, with a track record of independently delivering projects.

Experience working with databases.
Experience with interfaces: REST, SOAP, CSV, XML, JSON, authentication, error handling, and repeatable runs.
Ability to learn and integrate with unfamiliar, poorly documented systems.
Basic understanding of operations and deployment: Docker, CI/CD, reading logs.
Persistence in solving difficult problems, even if they are not elegant or take time.
Ability to question the 'why' and assess the value of automation.
Curiosity and the ability to leverage new technologies for added value, not just for their novelty.
Strong communication skills for direct client interaction.
