At GWI we're always looking for extraordinary people who thrive on making an extraordinary impact. Right now we're looking for a Senior-Front-End Engineer to play a key role in our Revenue & Enablement team in Athens. If that's you, and making a difference gets you out of bed in the morning, keep reading. It could be the start of something, well, extraordinary.
Sounds great, what will I be doing?

As our Senior Front-End Engineer, you'll join the Revenue & Enablement team, a cross-functional group responsible for building and scaling the systems that power GWI's subscription management, billing infrastructure, customer entitlements, and internal tools.

You'll help design and deliver interfaces that serve both our customers and internal teams, ensuring a seamless experience across payment workflows, admin controls, and platform-wide configuration systems. This is a high-impact role with a mix of user-facing and operational UI work, where attention to detail, performance, and maintainability all matter.

You'll be the primary front-end technical owner within the Revenue & Enablement team, responsible for shaping the architecture, design, and delivery of all front-end work. You'll work closely with your Engineering Manager, as well as with Product, Design, and backend engineers, to ensure high-quality and scalable solutions. As the front-end specialist, you'll help set standards, guide technical direction, and ensure consistency across the user interfaces you build.

What do I need to bring with me?

You'll need strong technical skills, an ownership mindset, and the ability to lead front-end work in a cross-functional team. This role is ideal for someone who enjoys working on platform-facing features, supporting both internal users and monetization-critical workflows. You don't have to tick all the boxes right away; the important thing is that you're willing to learn.

Here's what the team will be looking for:

Solid commercial experience with and TypeScript
Deep understanding of web platform fundamentals: HTTP/S, REST, performance optimization, and web security
Experience with testing methodologies (TDD, unit, integration testing)
Familiarity with CI/CD pipelines, and tools like Git and JIRA
Confidence working independently on front-end systems within a cross-functional, platform-oriented team 
Experience working on internal tools, admin panels, or platform-facing UIs, especially those related to billing systems or third-party integrations like Stripe or Salesforce

Equally important is attitude. We want people who think big (to make an impact), ask why (to find a better way), and show respect (to everyone, at every level, all the time). Those are our values, exemplified by our leadership team, and they're a big part of what we're looking for in you.

Interview steps
Preliminary phone call with the Talent Team (no video required)
First video interview with the hiring managers 
Second (and final*) video interview with the hiring panel, often including a presentation, followed by a values conversation with members of the wider GWI community.

Don't be alarmed if there are other stages in the process, it's all part of the plan for some of our roles.
