Full Stack Engineer

LanguageWire is a global leader in language and content services, dedicated to helping brands achieve their full global potential. Since our founding in 2000, we have continuously evolved and developed unique technology to facilitate seamless multilingual communication. Our worldwide network of language experts, coupled with an intuitive online platform, makes it effortless for brands to translate and manage multilingual content. 

The role you'll play 

We're launching a new team dedicated to modernizing and expanding one of our customer-facing tools — and we're looking for a Full Stack Engineer to join us in building it from the ground up. This is a newly formed team, not a legacy product, so you'll be part of shaping how it works from early on. 

The current stack is Vue.js on the frontend and Python on the backend, with a planned migration to .NET in the near future. We're looking for someone who can work across these three technologies — or is eager to grow into them — contributing to both new features and the upcoming stack migration, with support from more senior team members along the way. 

The team you'll be a part of 

You'll be joining a brand-new team at an early stage, led by our Tech Team Lead, as we build it out together. Alongside you, we're bringing on a Senior Full Stack Engineer and a Product Manager. It's a great opportunity to grow your skills in a close-knit, collaborative setting where your voice genuinely shapes how the team develops and works together. 

If you want to make a difference, make it with us by... 

• Developing and maintaining applications, including front-end interfaces, back-end services, and databases 

• Contributing to the architecture, design and implementation of new features and improvements 

• Implementing best practices for code quality, testing and deployment automation 

• Ensuring high-quality software through active participation in code reviews 

• Actively engaging in sprint retrospectives, refinements, daily stand-ups, and other team processes 

• Taking full ownership of the products and solutions you develop, eliminating bugs early in the process through TDD/BDD and other tests 

• Leveraging AI-assisted development tools and workflows to increase engineering velocity, while maintaining code quality and rigor 

• Sharing knowledge and support fellow developers, QA professionals, and support teams 

• Supporting team leaders with your expert knowledge and assist in customer meetings 

• Collaborating with our Site Reliability Engineer (SRE) on CI/CD pipelines to ensure seamless operations 

In one year, you'll know you were successful if... 

• You are fully integrated as part of the team and have built strong working relationships. 

• You actively contribute to maintaining a positive, collaborative, and knowledge-sharing team atmosphere. 

• You take full ownership of products and solutions, having delivered several major features to production with measurable impact.
