Web3 Developer Solidity Jobs in Berlin, Germany

About the Ethereum FoundationThe Ethereum Foundation (EF) is a global non-profit dedicated to supporting Ethereum’s long-term success. Our mission is to allocate resources to critical projects, advocate for Ethereum within the ecosystem, and promote its vision to the world. About the Role The EF builds and funds developer tooling at all levels of the stack, from languages and compilers to libraries to interact with the chain. As Developer Tooling Coordinator, you will help drive strategic technical decisions that shape Ethereum's developer ecosystem. This is a technical leadership role that blends hands-on development expertise with strategic planning and resource coordination.You'll help tackle critical strategic questions that require deep technical expertise, including: What should our strategy be around language support? How do we balance supporting legacy projects vs. newer promising experiments? What tools should the EF develop internally vs. rely on others? How should AI-assisted development reshape our tooling priorities and what new developer experiences should we enable?This role requires someone who can spot emerging trends, contribute to opinionated technical decisions based on leading indicators, and work collaboratively across teams—from diving deep into specific codebases to coordinating with EF leadership on grants and broader support strategy. RequirementsTo excel in this role, you should have extensive hands-on experience building on Ethereum—whether smart contracts, dApps, infrastructure, or developer tools—and strong, well-informed opinions about how the ecosystem should evolve.Ideal candidates have worked across multiple layers: smart contract development (Solidity/Vyper), client libraries (ethers.js, web3.py, etc.), infrastructure tooling (testing frameworks, deployment tools), or protocol-level work. You should understand the pain points developers face because you've felt them yourself.We're looking for someone who can seamlessly move between strategic discussions and diving deep into codebases. You should be comfortable reviewing implementations, contributing code, and helping make technical architecture decisions based on both quantitative metrics and technical intuition.Bonus points if you have experience managing resource allocation tradeoffs, leading technical initiatives across teams, or successfully identifying and acting on emerging technology trends before they become mainstream. Some of the domains and open questions you’ll be working on include: - Language & Framework Strategy: How should the EF balance support between established projects (Solidity, web3.js) vs. emerging ones (Vyper, new L2-native languages)? What dependencies and standards should we champion?- Developer Experience & AI Integration: What set of libraries are must-haves for Ethereum to provide a world-class DevEx to both new and existing developers? How should AI-assisted development tools integrate with our ecosystem? Which ones should be maintained by the EF vs. third parties?- Ecosystem Intelligence & Resource Allocation: What metrics (on-chain usage, GitHub activity, developer surveys) should guide our decisions? How do we spot emerging needs before they become critical gaps? How we work The EF isn’t a traditional workplace: it demands and rewards clarity, rapid execution, and genuine commitment to Ethereum’s mission. Distinct aspects of our work environment include:- Ethereum, period: the EF is in the privileged position where it only needs to consider what is best for Ethereum, without other constraints. This opens the door for unconventional strategies and bold approaches that wouldn’t be possible if we had to optimize for anything else. - Public by Default: Most contributions happen in the open, coordinating with stakeholders across the broader Ethereum community. This requires proactive engagement, clear communication, and effective collaboration without direct authority, even (and especially!) when consensus is challenging. - Agency, Impact & Accountability: You’ll have substantial freedom to define your own approach, experiment, and take ownership over your decisions. But with this autonomy comes clear accountability. Your work will be measured both by its immediate strategic impact, and also by its second-order effects across Ethereum’s ecosystem.This isn’t a fit for everyone, but for motivated, independent individuals, it’s uniquely empowering.Contract Details- This is a full-time role, fully remote, with optional offices in Boulder, USA and Berlin, Germany. Hours are flexible, but you should generally be available around “Eth o’clock” (14:00 UTC) for synchronous calls.  - Additionally, while this isn’t a strict requirement, you’ll benefit from being able to travel a few times a year to events related to your work, such as Devcon & Devconnect. - Lastly, anons are welcome to apply and work under a pseudonym, but will need to KYC with the Ethereum Foundation.
