Staff Full-Stack Software Engineer

📍Location: Greece 🏙️ Office requirement: Remote/ Flexible-first 📝 Employment type: Permanent/ Employee 📝 Linkedin Seniority Level: Mid/ Senior 

At GWI we’re always looking for extraordinary people who thrive on making an extraordinary impact. Right now we’re looking for a Staff Full-Stack Software Engineer to play a key role in our Platform team in our Software Engineering 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 Staff Engineer you’ll lead the development of APIs that drive seamless client experiences and integrations of GWI data across platforms. You’ll tackle complex technical challenges, guide the team through the entire API lifecycle, and make key architectural decisions, all while working with technologies like Go, React, Typescript, and Google Cloud.

It’s also fun; shaking things up is what working for a growing company is all about. So you’ll need to be flexible, comfortable with continuous change, and working in a high-tempo environment as we grow.

 

What do I need to bring with me? 🧳

You’ll need to be able to demonstrate the core skills this role requires. 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:

👉 Proven experience coding with Go, Java/C#, Ruby, Node.js, and working with frontend frameworks like React or Angular. 👉 Strong software development skills, with expertise in concurrency patterns, modular design, and optimizing client-facing APIs. 👉 In-depth knowledge of API design principles (authentication, versioning, error handling, security), with a focus on quality through Test Driven Development (TDD). 👉 Familiarity with continuous integration, deployment automation, and Agile methodologies (e.g., JIRA, Git), with flexibility to adapt to evolving requirements. 👉 Significant experience with Test Driven Development (TDD), ensuring high-quality, reliable API code. 👉 Solid knowledge and hands-on experience with continuous integration and deployment automation concepts. 👉 Ability to propose and drive architectural decisions that meet both client needs and business objectives. 👉 Experience integrating LLMs for natural language processing or AI-driven tasks is a plus. 👉 Excellent written and spoken English communication skills.

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) 👉 Technical task in Github  👉 Second (and final*) video interview with the hiring panel, discussing the task, 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.
