# Senior Backend Engineer [Weski](https://gurify.com/jobs?q=Weski) · Herzliya, Israel · Posted 2 weeks ago Senior [Backend](https://gurify.com/jobs/backend) [Apply on the original posting → (opens in a new tab)](https://www.comeet.com/jobs/weski/F8.00C/senior-backend-engineer/48.B47) ## Job description ### Who we are: WeSki is a self-service ski trip booking platform built for the modern traveller. Our vision is simple, to make great ski experiences available to everyone. We enable customers to build and book a fully custom ski holiday in minutes, combining flights, accommodation, transfers, ski passes, equipment and lessons in one seamless flow. Behind the scenes, our technology evaluates millions of trip combinations in real time. We dynamically connect inventory from thousands of suppliers, automatically optimise which components we bundle together, and present only options that really work. What used to take hours of research and coordination now takes a few clicks and finds much better results for the users. Every trip is fully customisable. Customers get the flexibility of building it themselves, with the security, protection, and support of a regulated holiday provider. Each trip is dynamically orchestrated in real time, with dependencies automatically managed across suppliers at scale, spanning 384 resorts in 21 countries across Europe, North America, Asia and Oceania. From booking to return, we manage the entire journey, so customers can relax and enjoy their holiday. We’ve recently crossed $100M in annual sales, including a $1M single day. Growth is accelerating, unit economics are strong, and the business funds its own growth. High transaction volume, complex infrastructure, real impact, delivered by a small, high-performing team. We operate in a ~$80B global ski market with no technology-native market leader. The industry is still dominated by traditional tour operators, with business models and infrastructure that have barely evolved in decades. This is a rare opportunity to define the future of ski travel at global scale. ### Key Responsibilities: - Design, develop, and evolve core backend systems and services, with an emphasis on scalability, performance, and maintainability. - Lead complex technical initiatives from concept through production, making architectural decisions that drive long-term impact. - Take end-to-end responsibility for backend production systems, including monitoring, troubleshooting, performance optimization, incident resolution, and infrastructure reliability. - Maintain high engineering standards through code reviews, testing, documentation, and best practices. - Continuously evaluate and adopt modern development tools to improve developer productivity and system quality. - Provide technical leadership and mentorship across the backend domain, influencing architectural standards and engineering culture. ### Requirements - 10+ years of backend development experience, with a strong focus on Node.js and distributed systems architecture. - Demonstrated ability to influence technical direction and drive architectural decisions. - Thrives in a fast-paced startup environment, demonstrating strong ownership, rapid execution, and a results-driven mindset. - Hands-on experience designing, building, and operating scalable microservices-based systems in production, including databases, caching layers, messaging systems, and high-traffic APIs. - Proven ability to architect, deploy, and operate production-grade cloud infrastructure (AWS/GCP), including networking, observability, CI/CD, security best practices, and cost optimization. - Experience integrating AI services or LLM-based workflows into production backend systems. - Strong communication and collaboration skills, with the ability to work effectively across teams. - Skier or snowboarder - always a plus. **Live in Weski’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role. We remove it as soon as it disappears at source. ## More jobs like this - FU [Senior Backend Engineer](https://gurify.com/job/senior-backend-engineer-at-fullpath-bb3d31e2cbc7) Fullpath · Jerusalem, Israel · yesterday - FU [Senior Backend Engineer](https://gurify.com/job/senior-backend-engineer-at-fullpath-073973bde66c) Fullpath · Tel Aviv-Yafo, Israel · today - RF [Senior Backend Engineer](https://gurify.com/job/senior-backend-engineer-at-riverside-fm-f3b5d958f92a) Riverside FM · Tel Aviv-Yafo, Israel · last week - RF [Senior Backend Engineer](https://gurify.com/job/senior-backend-engineer-at-riverside-fm-16b1a855f34e) Riverside FM · Tel Aviv-Yafo, Israel · last week - CL [Staff Backend Engineer - Moderation](https://gurify.com/job/staff-backend-engineer-moderation-at-cloudinary-bd05e4cc996d) Cloudinary · Israel · last week - LI [Backend Engineer](https://gurify.com/job/backend-engineer-at-linxsecurity-43a41de62183) Linxsecurity · Tel Aviv-Yafo, Israel · 2 weeks ago ```json {"@context":"https://schema.org/","@type":"JobPosting","title":"Senior Backend Engineer","description":"\u003Ch3\u003EWho we are:\u003C/h3\u003E\u003Cp\u003EWeSki is a self-service ski trip booking platform built for the modern traveller.
