Senior Backend Engineer

At Epignosis our mission is simple yet bold: To make learning technologies accessible to every business, regardless of geography, sector, or company size. And we’ve been doing just that for more than a decade, empowering millions of people to grow, learn, and thrive through technology that’s both powerful and affordable. 

We're rapidly becoming one of Greece's largest SaaS companies, serving 12,000+ companies and 11+ million learners worldwide with solutions like TalentLMS (an award-winning cloud LMS built for simplicity), eFront (an enterprise LMS), TalentCards (a mobile app for deskless training), and TalentHR (a lightweight HRIS for people operations). 

Our success is built on a team that believes that work should matter — not only to you, but to the world around you. We're looking for people who light up when solving hard problems, who care deeply about their craft, and who want to build something that genuinely helps people grow.

We are searching 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.

Benefits

We've built a workplace where people can do the best work of their careers. Here's how we support that:

• Competitive salary and bonuses. Strong base pay plus performance rewards at personal, team, and company levels.
• Stock options for everyone. Build software that empowers millions of learners worldwide, and own a piece of what you're creating. All team members can become shareholders, and these options have already changed lives.
• Your health is covered in more ways than one. Private health coverage for every team member, access to a nutritionist, and our in-house blood bank — all part of our health and wellness support.
• Comprehensive family support. We’re proud of our progressive family policy, one of the most generous in Greece.
• Daily meals and food allowance. Breakfast and catered lunch at our offices, plus a monthly meal allowance you control.
• Commute covered. OASA transport card or parking space near the office, whichever works for your commute.
• Hybrid work. Work from home and from our modern office in the heart of Athens.
• Employee Advisory Board. You have real input into company strategy through structured advisory sessions. Not common, but we think it should be.
• Learning budget for your growth. Coaching sessions, conferences, university degrees, creative pursuits — we fund it. Continuous learning is our mission and that includes you.
• Part of the Starttech Ventures ecosystem. Access to learning and collaboration across a portfolio of SaaS companies, with resources that support long-term growth.
