Principal Engineer - Vilgain s.r.o.

At Vilgain, we build our own technology because we do not want to be limited by off-the-shelf systems. We are growing fast, scaling across markets, and our e-commerce platform sits at the center of both customer experience and business performance. That is why we are looking for a Principal Engineer who will help us take the technical foundations of our platform to the next level.

This is not a role for someone who only wants to maintain existing solutions. We are looking for a strong individual contributor who can lead technically, push things forward, and help us rebuild key parts of our e-commerce stack so they are faster, more scalable, and ready for further growth.

What will be your mission?

Own key technical initiatives across our e-commerce platform

Improve customer experience, platform performance, and cost efficiency

Help split parts of the current monolith into a more scalable architecture

Drive technical improvements across tracking, integrations, and core platform capabilities

Make strong technical decisions with both engineering quality and business impact in mind

Help shape the future architecture of Vilgain’s e-commerce stack

Solve complex problems with high ownership and strong execution

Potentially support adjacent areas such as Finance Ops, depending on your profile

Who do we look for?

Strong Principal Engineer / Tech Lead profile

Experience building and scaling customer-facing digital products

Strong background in React and Next.js

Good understanding of APIs, GraphQL, performance, and scalable system design

Data-oriented mindset and strong product/business understanding

High ownership and strong problem-solving ability

Strong individual contributor who can provide technical leadership

Experience in e-commerce is a strong advantage

What do we offer?

You will have the opportunity to significantly influence the shape of a modern e-commerce stack in a company growing at exceptional speed, where engineering has a direct impact on both customers and business performance.

You will have a high level of technical freedom, real space to propose solutions your way, and the opportunity to be part of a major platform transformation that is critical for Vilgain. This is not a role where you will be working on marginal improvements. You will be solving core customer experience challenges and helping us build the foundations of a new e-commerce platform.

You can expect a fast-moving environment, high ownership, and no unnecessary corporate layers. If you enjoy solving difficult technical problems, want to see the direct impact of your work, and are excited by the idea of shaping an important technological transformation, this role will give you that.

We also offer fair compensation based on your seniority and impact.
