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

About the company

International company providing advertising accounts and infrastructure solutions for media buying teams, affiliate teams, and performance partners. We work with Google, Meta, TikTok, DSP, Native, and other ad platforms and providers.

Who we're looking for

A Team Lead Supply who will take ownership of the Supply team and be responsible for the effectiveness of the direction: task allocation, KPI and SLA control, supplier network development, and the quality of operational processes.

We're not looking for just a strong manager or a technical specialist — we need someone who knows how to organize the team's work, plan workload, control results, and grow the direction.

Experience specifically in our Supply model or in iGaming is not required — what matters more is managerial and operational experience and the ability to quickly get up to speed in a new subject area.

What you'll be doing

Team management:
— allocating tasks and workload among Supply Managers;
— planning the team's work and monitoring execution;
— controlling KPIs, SLAs, and quality of work;
— prioritizing tasks and overseeing key requests;
— identifying issues in the team's work and finding solutions;
— developing team members and sharing knowledge.

Supplier network development:
— sourcing and evaluating new suppliers;
— growing the existing base and key partners;
— finding alternative suppliers for non-standard requests;
— assessing supplier performance and quality;
— deciding on onboarding new suppliers;
— overseeing the team's work with the supplier base.

Commercial terms and partners:
— keeping prices, commissions, limits, and other terms up to date;
— approving changes to commercial terms;
— controlling quality and compliance with agreements with suppliers;
— resolving complex and non-standard situations with partners.

Operational processes:
— controlling SLAs and task deadlines;
— controlling the quality of delivery and account handling;
— controlling the accuracy of information in CRM and working databases;
— analyzing bottlenecks and process efficiency;
— developing and implementing new processes and regulations;
— initiating automation and improvements.

Cross-team collaboration:
— coordinating the department's work with account managers, finance, and dev teams;
— ensuring timely information handoff;
— escalating and resolving non-standard issues;
— preparing regular reporting on Supply's work for management.

What matters to us

— the ability to manage people and results, not just execute tasks yourself;
— the ability to set tasks, monitor execution, and work with KPIs;
— the ability to independently figure out a problematic request and see it through to resolution;
— the ability to work with suppliers and build long-term relationships;
— the ability to look for new solutions rather than relying only on the existing contact base;
— a systematic approach to information, turning the team's knowledge into clear processes;
— the ability to work under a heavy load of parallel tasks.

Requirements

Must-have:
— 2–3+ years of experience managing a team or an operational function;
— experience working with KPIs, SLAs, and workload distribution;
— experience working with partners / suppliers / vendors;
— strong organizational and communication skills;
— ability to analyze processes and identify areas for improvement;
— confident use of CRM and work tools;
— English — Intermediate+.

Nice to have:
— experience in Supply / Affiliate / iGaming / performance marketing;
— experience working with ad platforms;
— experience managing a team of Account / Affiliate / Supply Managers;
— experience building or optimizing operational processes;
— experience working with international suppliers.

We are a full-service digital agency founded in 2006. We focus on end-to-end solutions through three core areas: development, design, and marketing. Our work is driven by a data-first approach, and we actively advance AI capabilities – developing in-house AI products to streamline workflows and scale our clients' projects.

We already have a strong marketing team in place and are continuing to grow, so we're opening a new position for a Web Analyst.
 

We're looking for a specialist with 3+ years of commercial experience and a strong marketing background – ideally, someone who has worked in an agency environment or on large-scale e-commerce projects.
 

Key Responsibilities:

• Set up tracking and goals: GA4, GTM, events, dataLayer – from implementation to making sure the data is accurate and reliable.
• Build custom reports and dashboards using Claude.
• Answer business questions with data: why did sales drop, where are we losing money, and what should we do about it?
• Design and analyze A/B tests: from forming a hypothesis to drawing conclusions you can actually trust.
• Ensure data quality: investigate discrepancies between systems, attribution issues, and inconsistencies – and be able to explain where every number comes from.
• Automate routine tasks using AI agents.
   

Requirements:

• 3+ years of experience in web analytics: confident with GA4 and GTM, including events, goals, dataLayer, and debugging.
• AI as part of your daily workflow: using AI for analysis, queries, reporting, and automation.
• Understanding of advertising platforms: Google Ads and Meta – campaigns, metrics, and attribution.
• Practical knowledge of statistics: A/B testing, statistical significance, sample sizes, and seasonality.
• Strong analytical thinking: you don’t take numbers at face value or stop at the first plausible explanation – you dig 2–3 levels deeper to find the real cause.
• English: sufficient for written communication and calls.
   

What We Offer:

• Fully remote, full-time position with official employment.
• Western e-commerce projects with complex seasonality, where analytics is not just for reporting but directly drives real business decisions.
• A high level of trust: when it comes to data, the analyst has the final say in the discussion.
