senior backend engineer

At GWI we’re always looking for extraordinary people who thrive on making an extraordinary impact. Right now we’re looking for a Senior Backend Engineer to play a key role in our Software Engineering Department 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 Backend Engineer you'll contribute to building and optimizing the APIs and backend services that empower our clients to enhance their experiences. The role is perfect for someone who enjoys working on technicallly challenging projects, delivering high quality solutions, and collaborating closely with team members to drive results.

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 backend development experience: Strong proficiency in programming languages such as Go, Java/C#, Ruby, or Node.js, with a track record of building efficient and reliable backend systems

👉 API development expertise: Familiarity with API design principles, including authentication (OAuth, JWT), versioning, error handling, rate limiting, and security best practices

👉 Collaborative mindset: Ability to work effectively within a team, taking direction, sharing knowledge, and contributing to the success of joint projects

👉 Focus on quality and testing: Hands-on experience with Test-Driven Development (TDD) and ensuring high standards in code quality and reliability

👉 CI/CD familiarity: Understanding of continuous integration and deployment automation concepts to streamline development workflows

👉 Adaptability and resilience: Comfortable navigating changing requirements and fast-paced environments, with experience working in Agile settings using tools like JIRA and Git

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.

What’s in it for me? 🎁

You’ll do the sort of work that got you excited about your career in the first place - not as a cog in a machine, but as an individual whose contribution matters. So gigantic job satisfaction comes as standard, but it’s only part of the package. You’ll also get:
