Your Mission

At exmox, we are building the next European tech challenger in the user acquisition space. When you join exmox, you're stepping onto a global, highly competitive playing field, solving real problems in environments that push you beyond your comfort zone. We move fast, cut the noise, and focus on what actually matters, because in our industry, speed wins. With 50M+ platform downloads, we're rapidly scaling one of the most exciting innovations in mobile gaming: a rewarded user engagement and acquisition platform that helps players discover, and engage with games they enjoy - creating lasting value for both players and gaming studios.

As Tech Lead (f/m/x) you won't just be "coding tickets" or maintaining legacy systems. You'll be the technical leader of the team at the heart of our Python and Go platform, setting technical direction, raising the bar on engineering quality and staying hands-on in the codebase, with no people management required. You build it, you own it, working close to product and data and seeing the impact of your work in production. At exmox, we're embracing AI as part of how we work, not just what we build. We use AI tools to work smarter, cut down on repetitive tasks and spend our time where it actually moves the needle. If that mindset speaks to you, you'll fit right in.

If you're excited by complex systems, high traffic, data-driven decisions, and the chance to grow by solving challenging problems, we want to hear from you.

Responsibilities

• Technical leadership & architecture: Set technical direction and lead architecture and system design decisions, helping engineers balance speed, quality and long-term maintainability.
• Technical delivery: Turn product and business goals into executable plans, surface risks and dependencies early, and help the team deliver reliably from idea to production.
• Engineering quality, reliability & system health: Ensure systems are observable, reliable, testable and maintainable, and that production issues lead to concrete improvements.
• Knowledge sharing & mentoring: Guide engineers through their day-to-day work, sharing context and best practices, and help the team level up through code reviews and technical knowledge-sharing.
• Hands-on contribution: Remain an active contributor to the codebase, especially in technically complex or high-leverage areas.
• AI-assisted engineering practices: Champion AI-assisted engineering as a daily habit, using AI tools to accelerate development, testing, investigation and documentation.
• Cross-functional collaboration: Work closely with Product, Data and internal business stakeholders to turn business goals and operational problems into effective technical solutions.

Requirements

• Backend engineering expertise: Strong hands-on experience building and operating production backend systems with Python. Experience with Kafka, PostgreSQL and Redis is expected. Experience with Go is a plus.
• Distributed systems background: Practical experience with event-driven architectures and microservices, and a solid understanding of how to keep them reliable and maintainable at scale.
• Technical leadership: Experience leading technical discussions, guiding other engineers and raising the bar on engineering quality and best practices.
• Delivery ownership: Ability to take an ambiguous product or business goal and turn it into a concrete technical approach, sequence the work, manage technical risks and help a team get it safely into production.
• Production mindset: Comfortable owning systems beyond implementation. Think about observability, failure modes, operational readiness and how systems behave under real production load.
• Business-oriented engineering: Interest in understanding the business mechanics behind the systems you build and using that context to make better technical trade-offs.
• AI-native mindset: Genuine use of AI tools, including coding assistants and automation, as part of your daily workflow.
• Communication & mentoring skills: Ability to explain technical concepts clearly, share knowledge generously, and help others work through problems.

We Offer

• Speed is the feature. We move fast, test fast, and multiply our pace with AI, because action creates information and small wins compound.
• Focus on the essential. Done is better than perfect. We stay focused on what actually moves us forward.
• See it. Own it. Solve it. We're a place for doers. "Not my job" isn't in our vocabulary.
• Respect others. Trust multiplies. Respect is non-negotiable.
• Perks that help you focus on what matters. Transport subsidy, learning budget, wellness and gym, workation, bi-weekly team lunches, and more.

Please note: this is not a remote only position, we offer a flexible hybrid model here in Hamburg, Germany - working from home on Mondays & Fridays, coming to the office on Tuesday, Wednesday & Thursday!
