In-App Technical Support Team Lead

Location: Poland We Are: RTB House is a next-generation performance demand-side platform (DSP) that uses proprietary Deep Learning AI algorithms to help brands grow. The company is the market leader in driving performance using Deep Learning across the entire purchase funnel. Founded in 2012 and now operating in 90+ markets, RTB House has always been private-by-design. It embraces first-party advertising and a relentless approach to innovation. RTB House offers end-to-end Deep Learning-powered AdTech products and solutions to maximize conversion, drive new customer acquisition, create engagement, and fuel long-term demand for a global base of clients. In 2026, RTB House launched rtb.com, a self-service platform specifically designed to allow small and medium-sized businesses and agencies to deploy auto-built creatives and maximize performance on any budget. Our In-App team in Poland consists of 6 people and is part of Traffic SEDA (Solutions Engineering & Data Analytics), a group of technical teams in Poland and Brazil supporting RTB House campaigns globally. The team is the technical backbone for mobile app and mobile game retargeting campaigns: we resolve attribution, tracking and integration issues, onboard new advertisers and MMP integrations, and keep in-app measurement reliable across the globe. We are looking for a Team Leader who will own this team's results and development, while staying close to the technical work. You Will: Lead a team of 6 in-app tracking specialists: set priorities, manage performance, give regular feedback, and support each person's development. Own the team's SLAs and the quality of ticket resolution, and make sure the right things get fixed first. Act as the escalation point for the most complex attribution, tracking and data-consistency cases, and drive them to a root cause together with internal technical departments. Stay hands-on: around 40% of your time will go to technical investigations across RTB House systems, MMPs and third-party integrations. Have an active role in the internal projects and processes connected to the InApp initiatives within the company Build strong working relationships with Technical Account Managers and business teams; set clear expectations and communicate status in a way that non-technical stakeholders can act on. Run hiring for the team: define needs, screen candidates, and onboard new joiners. Improve how the team works: internal tools, monitoring, processes, documentation and knowledge sharing related to in-app tracking and measurement. Represent the team within Traffic SEDA and towards other departments, and bring back what the team needs to deliver. Desired Experience: Strong, proven technical knowledge of mobile attribution and in-app tracking: MMP platforms (AppsFlyer, Adjust, Branch or similar), postbacks, deep links, attribution windows and deduplication logic - this is a hard requirement. Experience leading a team, or a senior-level track record in a technical support/solutions role with clear readiness to step into a leadership position. Ability to analyze raw data to find the cause of a problem: Excel, SQL and internal tools. Working knowledge of JavaScript or another scripting language, enough to review and validate tagging and postback mapping solutions. Fluent English - technical issues are discussed in this language on a daily basis. Clear, structured communication, especially when describing technical issues to other departments. Analytical approach to problem solving and strong self-organization. Nice to have: Experience with tracking and analytics stacks beyond MMPs (Google Analytics, Firebase, internal BI systems). Experience with ticket-based support work and SLA management. Interest in new technologies, online advertising or e-commerce We Offer: A flexible cooperation model - remote or hybrid - tailored to your preferences. Form of cooperation: contract of mandate or B2B contract. A leadership role with real ownership: you shape how the team works, not just what it works on. Collaboration with an award-winning organization that shapes the future of online marketing globally and is one of the fastest-growing tech companies in Europe (Deloitte Fast 50 CE, Financial Times 1000: Europe's Fastest-Growing Companies). A truly international environment at the forefront of ad-tech, working with the best people in one of the fastest-growing segments of online advertising.
