We are looking for an Associate Frontend Engineer to help us build and refine the user interfaces that keep business operations moving smoothly. At Tech Pipeline, we resolve the friction in operational processes, fixing the UI layout bugs and broken data forms that slow client teams down. For this project, our partner is a central European logistics business, and you will help build interface tools that make their daily routing and exception handling straightforward. Our partner is currently facing daily challenges where internal operators are stuck reconciling transport data using spreadsheets and slow, legacy admin screens. Instead, we look at the exact places where the interface lags, why input forms fail silently, and why the team is forced to copy‐paste data between tools.
As an Associate Frontend Engineer, you will work within a hybrid model: you will work from home for part of the week and join us in person at our partner's workspace during scheduled collaboration days to sit directly with the operators. You will help write clean,



component‐based frontend code to replace clunky forms, design clear validation cues, and ensure that when a routing rule fails, the operator sees a clear error message instead of a generic system crash. Build and update modular UI components using HTML, CSS, and basic JavaScript.
Sit alongside logistics operators during hybrid collaboration days to observe where current interfaces cause friction.
Trace frontend error logs to identify why specific forms or input fields are rejecting user data.
Conduct regular tests between our frontend interfaces and partner APIs to make sure data renders correctly.
Test validation rules on different devices to make sure forms work correctly on warehouse handheld units.
A solid initial understanding of HTML, CSS, and core JavaScript logic.
The ability to use browser diagnostic tools to inspect elements and track network errors.
Clear written communication skills for writing change logs and interface
