To democratize access to culture and entertainment. With our proprietary cutting-edge technology and data-driven approach, we’re revolutionizing the way people engage with live entertainment.\nEvery month, our platform inspires over 300 million people in +55 countries (and counting) to discover unforgettable experiences while also empowering event creators with our data and technology, helping them scale, innovate, and enhance their events to reach new audiences. \nOur results? We’ve teamed up with major industry leaders like Netflix, F.C. Barcelona, and Primavera Sound, presented international award-winning experiences, and are backed by several leading global investors! Impressive, right? \nTo achieve our mission, we are looking for bar-raisers with a hands-on mindset who are eager to help shape the future of entertainment!\nReady to be part of the experience? \nNow, let’s discuss this role and what you will do to help achieve Fever’s mission.\nWe are looking for aStaff Product Engineer to join our Data Team. This is a role for an engineer who cares deeply about product impact, user experience, and how systems connect to real business outcomes. You will work across the full stack, from the interfaces users interact with to the services and data layers that power them, and bridge the gap between our AI and data capabilities and the products people actually use. You won't just take tickets and ship code. You'll own features end-to-end: shaping the problem with Product and Design, building it, defining success metrics, and iterating based on real data. If you thrive in ambiguous, high-leverage environments, love shipping with judgment, and want your engineering work to be visibly tied to outcomes that matter, you'll fit right in.\nTech environment\nThis role is intentionally not defined by one framework or specialty. That said, you will likely operate across the full stack: a modern TypeScript web platform where several frontends and frameworks coexist, and where moving between them matters more than allegiance to one, that also ships inside our native apps through webviews and a native/web bridge; Python-based services and APIs; relational, NoSQL, and search datastores, data warehouses, and SQL; event-driven and distributed systems; cloud infrastructure, containers, and CI/CD pipelines; and observability tooling. Depending on the project, you may also work with LLM APIs and agent-based workflows, retrieval patterns, data orchestration, and product analytics and A/B experimentation.\nNice to have\nStrong TypeScript and depth in at least one modern web framework. Our web platform is a large monorepo combining several frontends, where Angular and Astro/Svelte coexist. Comfort moving across frameworks matters more than allegiance to one.\nStrong componentization skills: designing reusable components and shared modules whose logic lives in framework-agnostic packages, including web features that ship inside our native apps through webviews and JavaScript/native bridges. Our apps are Kotlin/Jetpack Compose and Swift/SwiftUI; you won't own them, but you'll integrate deeply with them.\nSound judgment on when to render server-side vs client-side (or hybrid), driven by functional and non-functional requirements such as SEO, performance, personalization, and caching, rather than framework defaults.\nExperience working on internal platforms, operational tools, or product-heavy backend systems.\nExperience with Python frameworks such as Django or FastAPI.\nExperience with PostgreSQL, Snowflake, DynamoDB, Redis, OpenSearch, and SQL-heavy applications.\nFamiliarity with event-driven architectures or messaging systems such as Kafka or RabbitMQ.\nExperience with AWS, Docker, Kubernetes, Terraform, or similar infrastructure patterns.\nFamiliarity with observability and monitoring tooling (Datadog or similar).\nExposure to AI-enabled product development: LLM integrations, agent frameworks (LangGraph/LangChain), LLM observability (Langfuse), RAG patterns, or workflow automation.\nFamiliarity with Google Analytics 4 and Google Tag Manager. Product tracking at Fever runs through Dataverse, our in-house unified behavioural event layer built on server-side GTM, so knowing how GA and GTM work is enough to find your way around. We also use Mixpanel.\nFamiliarity with product experimentation: A/B testing, feature flags, and edge-side experimentation. We bucket anonymous users and run rollouts at the CDN edge (CloudFront Functions), with Statsig and Optimizely as the experimentation platforms.\nExperience working on 0 to 1 initiatives or undefined problem spaces.\nDemonstrated leadership through ownership of difficult projects with broad impact.\nWhat success looks like\nYou turn ambiguous opportunities into working systems or products that create clear value.\nYou help teams make better trade-offs and avoid overengineering, fragmentation, and local optimization.\nYou improve not only what gets built, but also how decisions are made.\nYou become a trusted technical leader for important cross-functional initiatives.\nYou increase the leverage of other engineers and teams through your judgment, technical direction, and execution support.\nYou help connect engineering work to real operational and business outcomes.\nWho will thrive in this role\nYou will likely thrive here if:\nYou are energized by ambitious, messy, high-leverage problems.\nYou like operating where priorities evolve and the path is not fully defined.\nYou care more about impact than about staying inside a narrowly defined engineering lane.\nYou enjoy combining engineering depth, product thinking, and business context.\nYou naturally look for the highest-leverage way to move a system, a team, or a product forward.\nYou want to play a meaningful role in shaping how the company builds and scales.\nWhy join Fever\nYou will work on some of the company's most strategic problems.\nYou will have real ownership and visible impact.\nYou will help shape products, systems, and capabilities that matter across the business.\nYou will work in an environment that values ambition, adaptability, pragmatism, and execution.\nYou will be surrounded by smart, driven people who care about building things that matter.\nBenefits & Perks\nFlexible schedule\nBonus\nStock options\n40% discount on all Fever events and experiences\nHealth insurance from Day 1\nEnglish or Spanish Lessons\nWellhub Membership\nCobee (tax free allowance on restaurants and transport)\nPossibility to receive in advance part of your salary by Payflow\nThank you for considering joining Fever.
