Middle / Senior PHP / JS Engineer

Location & English requirements:
This is a fully remote position within the European Union, with priority given to candidates based in Poland. Other EU locations may also be considered.
Strong English (Upper-Intermediate/C1 or higher) is required - all calls, discussions, and documentation happen fully in English, and you'll be expected to actively participate in technical conversations: asking questions, raising concerns, proposing alternatives. If your English is below this level, you likely won't feel comfortable in this role's day-to-day communication - so please keep that in mind before applying.

Who we're looking for:
This is not a "heads-down, ticket-by-ticket" role. Our client's team is a well-established international group of up to 50 people, and they're explicit about what doesn't work for them: people who stay quiet in discussions, who wait to be told exactly what to do, or who seem to be splitting focus with other projects.

What they want instead:

• Someone who speaks up - asks clarifying questions, flags risks, and isn't afraid to challenge an approach if they see a better one
• Someone who treats this as their project, not a rotation - full commitment, no split attention across other engagements
• Someone comfortable operating with a good degree of autonomy, while staying closely aligned with the team
• Someone who brings ideas to code reviews and architecture discussions, not just implementations

If that sounds like you, and your English lets you do it comfortably - read on.

Required skills:

• Commercial experience with PHP and JavaScript, Middle+/Senior level
• Experience with modern JS frameworks (Vue.js preferred)
• Strong understanding of OOP, interfaces, and clean code principles
• Experience with PSR-4 standards and service-oriented architecture (SOA)
• Experience with unit testing (PHPUnit or similar)
• Upper-Intermediate+ English, spoken and written
• Demonstrated ability to communicate proactively: asking questions, giving feedback, contributing opinions in team settings

Will be a plus:

Experience with MediaWiki

Experience with enterprise web platforms or CMS

Prior experience working in distributed international teams (not local outsourcing setups)

Project description:

Our client is a German product company focused on enterprise wiki solutions based on MediaWiki, used by companies worldwide for internal documentation, collaboration, and knowledge management.

This is a long-term product, not a short-term outsourcing project - the team has been building and refining this platform for years, with a strong focus on code quality, usability, and sustainable architecture. The team (Germany + EU, up to 50 people) genuinely values open communication and healthy work-life balance - but that culture depends on people who participate in it, not just execute tasks silently.

Responsibilities:

• Develop and maintain customer-specific features for BlueSpice
• Continuously improve and modernize the product
• Support the team with bug fixing and error analysis
• Write clean, maintainable, and testable code
• Actively participate in code reviews and technical discussions — bring your perspective, don't just approve
• Work closely and communicatively with the German product team
• Technology stack: PHP, JavaScript, Vue.js, MediaWiki, MySQL, Elasticsearch, PHPUnit, SOA, PSR-4

We offer:

• Long-term, stable product project - full commitment expected, no parallel projects
• Direct collaboration with the German team
• Predictable workload and healthy work environment
• Interesting technical challenges and a mature, well-maintained codebase
• Competitive compensation
• Paid vacation and sick leave
• Optional business trips to Germany
• Professional growth within a strong product team
