Senior Backend Engineer (PHP / Symfony) - Room Estate team
Holycode
This is a senior-level role, which means it's not typical entry-level work. But if you have strong PHP fundamentals and want to own backend architecture decisions from day one, this is a real opportunity to work on modernizing a live system rather than just building features someone else designed.
You'll design REST APIs in PHP 8+ and Symfony, build scalable services that integrate with existing Drupal and MySQL systems, and make real choices about database structure, query optimization, and cloud architecture. You'll work closely with a mobile developer and have actual ownership over what gets built and how.
This fits you if you've shipped PHP projects, understand API design, and want to see how backend systems scale in the real world. A portfolio or GitHub showing Symfony or solid PHP work will help your application.
Apply through CareerJumpship to submit your resume, portfolio, and any relevant projects. Be direct about your experience level and what you've built.
