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
