Your mission We're looking for product-minded engineers to join our diverse and driven team. We really value collaboration, making an impact, and continuous learning. Our product development team is based in Berlin, but we have folks working all over Europe, and you'll work closely with an experienced and supportive team. Your profile We are looking for a Senior Fullstack Engineer with high Expertise in Go/React,TypeScript to join a diverse, product-minded team that values collaboration, impact, and continuous learning. We are a remote-first team working across Europe (within +/- 1 hour of CET), where engineers are expected to be comfortable navigating the entire stack (both Frontend and Backend). In this role, you won't just be "flipping a switch" on the frontend; you will be architecting features from the database to the browser. You’ll join an experienced and supportive team where you’ll have a significant voice in shaping both our technical direction and the product itself. About You This is a role for a generalist who enjoys the variety of switching between building sleek interfaces and robust server-side logic. You’ll thrive here if you can: - Own the Full Lifecycle: Build, scale, and maintain modern web applications where the logic is split evenly between TypeScript frontend and our Go (Golang) backend. - Bridge the Gap: Design and implement clean APIs in Go while ensuring they are seamlessly integrated into a performant, accessible React frontend. - Architect for Scale: Maintain high standards for code quality and performance across the entire stack, from frontend component libraries to backend microservices. - Collaborate Broadly: Work closely with Product and Design to turn ambiguous requirements into polished features. - Master the Ecosystem: Help evolve our infrastructure and lean into AI tools, understanding their strengths and limitations to accelerate our workflow. To Be Successful in This Role, You’ll Need: - Experience: at least 6+ years of professional software engineering experience in a production environment. - The Backend: Proven experience architecting and maintaining high-scale web APIs. Golang is our primary language. You don't need to be a Go veteran on day one—as long as you have rock-solid backend fundamentals and are willing to master Golang. - The Frontend: Fluency in React and TypeScript. You move comfortably through modern tooling (e.g., Redux Toolkit, Styled Components, Storybook) and you care deeply about quality, ensuring your features are backed by solid testing frameworks (Jest, Cypress, or Playwright). - System Ownership: A "DevOps" mindset, comfortable with CI/CD, automated testing, and version control. - Communication: Fluent English and the ability to explain complex technical trade-offs to non-technical stakeholders. What we care about - Teamwork: collaborating and supporting each other within engineering and across functions - Inclusion: creating an environment where everybody can bring their whole self and do their best work - Ownership: empowering you to do the work that is most impactful - Sustainability: balancing work with family and personal hobbies so we can be at our best - Growth: supporting each other’s learning and development Why topi? - Impact from Day One - Your ideas are valued, and you actively shape our direction. No long feedback loops or complex hierarchies - you’ll have a direct impact on what you do. - Trust - We believe in our mission and in our team, offering trust-based working hours, permanent contracts, flexibility for home-country working. - Flexibility - We offer flexible working hour arrangements to ensure a healthy work-life balance. - Team Spirit - Shared rituals connect us, whether online or offline. We have regular formats like all-hands meetings, demo sessions, quizzes, and offsites - perfect opportunities to spend time as a team. - Personal Growth - Learn from experienced colleagues and leverage the latest technologies and methodologies to succeed in your role.
