Senior Backend Engineer

At Epignosis, we build workplace learning software that enables more than 70,000 teams worldwide to offer training to millions of people. Our portfolio of tools can be used by organizations of any size and includes TalentLMS - a zero-overhead cloud LMS, eFront - an enterprise LMS, TalentCards - a mobile app for training the deskless workforce, and TalentHR - a lightweight HRIS to manage people ops. We are competing with the world’s top eLearning solutions and we aim at becoming world’s #1.

We're on a mission to democratize training by developing simple, accessible, and affordable software. We count 12.000+ companies as customers and with more than 11 million users logging in to use our platforms, we are a much-loved global leader in learning tech. At home, we are quickly becoming one of the largest SaaS company to come out of Greece.

We are looking for a Senior Backend Engineer to join our TalentLMS team. The ideal candidate will have extensive experience in backend development and a strong understanding of web development best practices. While our codebase is primarily in PHP, we’re looking for engineers with strong backend experience in any language. We care more about how you think, collaborate, and solve problems than what languages you’ve used.

You will work closely with fellow developers, as well as our product and design teams, to ensure our applications are robust, scalable, and user-friendly. You’ll take ownership of complex features, help improve our codebase and architecture, and support the team in delivering high-quality software.

Responsibilities

As a Senior Backend Engineer, you will:

• Take ownership of complex features and services from design to delivery and maintenance.
• Work closely with backend, frontend, DevOps and QA engineers, as well as product managers and designers.
• Mentor fellow developers and help grow their skills through feedback, collaboration, and shared ownership.
• Transform user stories into reliable backend code and scalable API endpoints.
• Break down large projects into smaller, manageable parts and drive them to completion.
• Actively participate in architectural discussions and help shape the team’s technical direction.
• Refactor legacy systems using modern development practices and tools.
• Support team health by encouraging collaboration, accountability, and technical excellence.
  

Requirements

To be successful in this role as a Senior Backend Engineer, you should:

• Have 5+ years of experience in backend development. 
• Experience with PHP is a plus.
• Have strong analytical skills and a solid foundation in algorithms, data structures, and software design.
• Understand backend systems at scale, including performance, security, reliability, and data consistency.
• Be experienced with writing and consuming modern APIs.
• Be familiar with unit testing, and ideally, TDD.
• Be comfortable working on high-volume, high-traffic applications.
• Be familiar with CI/CD tools and modern development workflows.
• Experience with AWS is a plus.
• Be thoughtful, open, and generous with your time and knowledge.
• Have a degree in software engineering, or be able to explain why you don’t need one.
