Closed job - No longer receiving applicants

MagmaLabs is an ecommerce and software consultancy that builds software solutions for emerging, mid-size, and growing companies using innovative technologies, top talent, and nearshore teams. We are looking for at least 5 Senior Software Engineers to join the engineering department here at MagmaLabs, with extensive experience building web applications using business-grade technologies using Ruby on Rails, updating apps with new versions of Rails, that enjoy unit testing, who are always looking for optimal performance and have an interest in providing comprehensive and high-quality solutions to customers.

Senior Software Engineer (Full Stack Ruby - Contractor)

To qualify you must possess at least 10 years of experience in custom software development, having delivered plenty of production web and/or mobile applications. Because we are one of the most prominent Ruby on Rails shops in the world, you should have at least five years of experience building and maintaining web applications using Ruby on Rails, preferably more. As a full stack engineer, you should be able to independently put together solutions from JavaScript and CSS on the front-end, to SQL and cloud-based deployment configuration pipelines on the backend.

The most qualified candidates for this position will possess proven leadership capabilities either in corporate team settings or within the open source community, and you should be able to comfortably demonstrate full confidence in problem analysis, solution design, and the crafting of solutions with well-tested code.

We are growing fast and are looking for very experienced senior software engineers with full-stack web development experience to reinforce the technical backbone of our consulting organization.

At MagmaLabs we pride ourselves on a well-nursed culture of teamwork, diversity, and recognition, and for that reason we look to add people who are collaborative, optimistic, and curious. On a day-to-day basis, we expect all our people to be passionate, humble, and hungry for new challenges, possessing a growth mindset and mindful of opportunities for self improvement.


You should possess excellent English verbal and written communication skills, and be excited about putting those skills to use with our consulting clients and while mentoring less experienced developers.
