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 engineering bar, and staying hands-on in the codebase, with no people management required.
You build it, you own it. You’ll work closely with Product and Data, 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.
As the team’s primary technical leader, you’ll set technical direction and lead architecture and system design decisions, helping engineers balance speed, quality, and long-term maintainability. You’ll also collaborate with other Tech Leads and senior engineers on broader technical decisions, keeping system boundaries clear.
You’ll be accountable for the technical execution of the team’s work. You’ll turn product and business goals into executable plans, surface risks and dependencies early, and help the team deliver reliably from idea to production.
You’ll set and maintain the engineering bar for the team, ensuring systems are observable, reliable, testable, and maintainable. You’ll turn production issues into concrete improvements and proactively address technical debt, reliability risks, and architectural weaknesses that threaten our ability to move quickly and safely.
You’ll 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. You’ll create ownership rather than becoming a bottleneck, stepping in when complexity or risk requires it. You’ll also help engineers grow into greater technical ownership and create more decision-making capacity within the team.
Alongside your leadership responsibilities, you’ll remain an active contributor to the codebase, especially in technically complex or high-leverage areas, while ensuring the broader team retains ownership of the systems it builds.
You’ll champion AI-assisted engineering as a daily habit, using AI tools to accelerate development, testing, investigation, and documentation while maintaining strong engineering judgment and review standards. You’ll help the team adopt effective practices rather than simply increasing tool usage.
You’ll work closely with Product, Data, and internal business stakeholders to turn business goals and operational problems into effective technical solutions, balancing pragmatic delivery with long-term system health.
Strong hands-on experience building and operating production backend systems with Python. You’ll work with Kafka, PostgreSQL, and Redis day to day, so solid experience with these or comparable technologies is expected. Experience with Go is a plus, and you’re comfortable working across both. FastAPI or comparable modern API frameworks is also a plus.
Practical experience with event-driven architectures and microservices, along with a solid understanding of how to keep them reliable and maintainable at scale.
Experience leading technical discussions, guiding other engineers, and raising the bar on engineering quality and best practices, without necessarily having formal people-management experience.
The 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.
You’re comfortable owning systems beyond implementation. You think about observability, failure modes, operational readiness, and how systems behave under real production load.
You’re interested in understanding the business mechanics behind the systems you build and using that context to make better technical trade-offs.
You genuinely use AI tools, including coding assistants and automation, as part of your daily workflow, and you’re comfortable helping others use them effectively and responsibly.
You can explain technical concepts clearly, share knowledge generously, and help others work through problems rather than simply solving everything yourself.
Speed beats rocket science. We move fast, test fast, and multiply our pace with AI, because action creates information and small wins compound. A fast failure is a lesson we learn from; a slow one is a problem we can’t afford.
Done is better than perfect. We stay focused on what actually moves us forward and protect people’s time from anything that doesn’t. We’re direct in how we communicate, too: no rambling, no unnecessary detail.
The first to see it is best placed to fix it. We’re not a place for comfort; we’re a place for doers. “Not my job” isn’t in our vocabulary. If you spot something, you help make sure it gets solved.
Respect is non-negotiable. We disagree with ideas, never with people. Trust is built through consistency, a thank you, a moment of listening, and owning your mistakes.
We offer benefits that support your well-being, development, and work-life balance, including:
The perks are great, but the real reason people join and stay is the challenge, the ownership, and the drive to win together.
Please note: This is not a fully remote position. We offer a flexible hybrid model based in Hamburg, Germany:
