Senior Go Engineer, Full Stack
topi GmbH
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.

About Etera Etera is building the first AI-native corporate travel platform for the GCC market — designed from the ground up for how businesses in the region actually operate. We're a lean, high-conviction team replacing legacy TMCs with autonomous agents, real-time inventory, and a product experience that doesn't feel like it was designed in 2009. The Role We're looking for a Senior AI Fullstack Engineer who can own the full stack — from a smooth React Native mobile experience to TypeScript backend services and the AI/LLM layer that powers our multi-agent infrastructure (OPUS Prime). If you think in systems, ship fast, and find it natural to reason about both user-facing product and underlying model behavior, this role was built for you. What You'll Own - Mobile-first product: Build and maintain Etera's React Native app (Expo/TypeScript) — booking flows, real-time updates, multilingual UX (Arabic/English). - Backend services: Design and extend our TypeScript backend, including booking APIs, supplier integrations (PKfare, RateHawk, Hotelbeds), and webhook orchestration. - LLM integration: Work directly with Claude (Anthropic API) and our multi-agent OPUS Prime system — building, tuning, and extending AI pipelines for travel intent detection, QA, and automated engineering reports. - End-to-end delivery: Take features from spec to production. Own the full lifecycle — architecture, implementation, testing, deployment. - Infra & reliability: Firebase Auth (OTP, Apple, Google), EAS Build/TestFlight pipelines, and CI/CD hygiene across the stack. - Code quality: Participate in security audits and peer review within a small, high-trust engineering team. Tech Stack Frontend / Mobile: React Native + Expo, TypeScript, Firebase Auth (OTP, Apple, Google), EAS Build / TestFlight, Native iOS/Android context. Backend / AI: TypeScript (end-to-end), Anthropic API / Claude, Mastra (agent orchestration framework), LangChain (chains, tools, memory), Zeabur / cloud deployment, REST + Webhook integrations. You've Built and Run Agent Teams. Plural. This is not a role for someone who has experimented with LLMs on side projects. We're looking for engineers who have designed, shipped, and actively maintained multi-agent systems — and who understand what it takes to keep them reliable in production. - Proven agent team ownership: You have built one or more autonomous agent teams from scratch — defined their scope, wired their tools, managed inter-agent communication, and own their continued operation. - Self-validating mindset: You don't hand off agent output blindly. You act as the primary validation layer for the systems you build — designing evaluation criteria, catching failure modes, and iterating on agent behavior based on real output quality. - Cross-domain fluency: Your agents have touched multiple domains — not just one narrow use case. You can reason about agent behavior across booking logic, data quality, QA pipelines, code review, or content generation without needing a specialist in each area. - Maintenance discipline: You have a track record of keeping agent systems healthy over time — prompt drift, tool failures, context window management, regression testing. Not just shipping and moving on. - Full-stack integration: You connect agent teams to real product surfaces — not just notebooks or internal tools. Your work shows up in APIs, mobile interfaces, or backend workflows that real users depend on.
