Every 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.
Our 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?
To achieve our mission, we are looking for bar-raisers with a hands-on mindset who are eager to help shape the future of entertainment!
Ready to be part of the experience?
Now, let’s discuss this role and what you will do to help achieve Fever’s mission.
There is a belief that only Silicon Valley can create global technology leaders and that the best career opportunities are outside our borders. But Fever was born with the opposite belief: Spain has world-class talent, and from Spain you can build a global tech leader.
That’s why the “Beca de Excelencia” was created: to support and retain exceptional talent and accelerate the careers of future top engineers.
Our goal is to offer students the opportunity to start their professional career in a high-performing engineering team, surrounded by international professionals, an entrepreneurial mindset, and leaders in their respective fields.
Get all the information about the program in becasexcelencia.com
Because you won’t just be an intern — you’ll be a full member of the engineering team in a global tech company.
Fever has already found product-market fit and reached break-even, and we are now in a stage of strong execution and scaling. That means real challenges, real impact, and real ownership.
You’ll work alongside experienced engineers in software, product, data, growth and operations, on projects that impact millions of users. At Fever, Software Engineers have a high level of ownership. That means you will be involved end-to-end, from understanding the problem and designing the solution, to coding, deploying to production and monitoring performance.
As a Software Engineer at Fever, you will have real ownership from day one. Engineers are responsible end-to-end: understanding the problem, designing the solution, implementing it, deploying it to production and monitoring its performance.
We build scalable systems using a distributed services architecture, applying best practices such as Domain-Driven Design and clean architecture principles.
While this is a graduate program, you will be working with modern production systems and technologies used at scale.
Our core stack includes:
We focus on building reliable, scalable software used by millions of users worldwide.
Thank you for considering joining Fever. We cannot wait to learn more about you!

Role: Senior ML-Engineer
Location: Spain, Remote
Language: Russian-speaking team; Strong English required (B2)
Fundraise Up is a modern fundraising platform built to make donating to nonprofits as fast and convenient as possible. We continuously innovate to reduce page load times, boost conversion rates, and support a wide range of payment methods. Each month, people around the world contribute tens of millions of dollars through our platform.
The world’s leading nonprofit organizations trust Fundraise Up. UNICEF, the most prominent UN charity, uses our platform for 100% of its online fundraising. So does the American Heart Association, the Alzheimer’s Association, and many others. We’re proud to maintain a 4.9 out of 5 rating on leading review platforms.
We serve the enterprise segment, with a primary client base in the US, Canada, UK, and Australia.
Our product development team is currently at 150+ and growing. Team members are located across Spain, Serbia, Poland, Portugal, Turkey, Cyprus, Georgia and Armenia. We primarily communicate in Russian.
We’re a tight-knit, high-impact team where every task matters. It’s a dynamic, collaborative environment where smart, curious engineers support one another, share knowledge, and strive for excellence. We encourage open dialogue and host bi-weekly engineering meetups to explore technical topics and showcase team insights.
We're looking for an ML Engineer with 5+ years of production experience to strengthen our ML team. We operate as an internal service and centre of excellence for 10+ product teams at Fundraise Up. This means you won't be tied to a single feature: one day you might be optimising donation amounts and upsell offers, and the next you could be building a smart assistant for the admin panel or working on transaction classification.
We actively use not only classical ML, but also RL, and we're expanding our LLM-based solutions — prompt engineering and pipeline design with LLM APIs (OpenAI and equivalents). That's why we're looking for someone with a broad mindset who isn't afraid to experiment and can choose the most effective approach for each task.
The project's main audience and business team are based in the US. Although the product development team is Russian-speaking, you may occasionally need to write in English.
Core: Python (uv, ruff), FastAPI, Pydantic, Docker
Models: CatBoost, Uplift Modeling (CausalML), OpenAI (RAG, Prompt-Engineering)
Data: ClickHouse, MongoDB, pandas, Polars, Redis
MLOps: MLflow, Airflow
Monitoring: Grafana, Sentry

Now, let’s discuss this role and what you will do to help achieve Fever’s mission.
There is a belief that only Silicon Valley can create global technology leaders and that the best career opportunities are outside our borders. But Fever was born with the opposite belief: Spain has world-class talent, and from Spain you can build a global tech leader.
That’s why the “Beca de Excelencia” was created: to support and retain exceptional talent and accelerate the careers of future top engineers.
Our goal is to offer students the opportunity to start their professional career in a high-performing engineering team, surrounded by international professionals, an entrepreneurial mindset, and leaders in their respective fields.
Get all the information about the program in becasexcelencia.com
Because you won’t just be an intern — you’ll be a full member of the engineering team in a global tech company.
Fever has already found product-market fit and reached break-even, and we are now in a stage of strong execution and scaling. That means real challenges, real impact, and real ownership.
You’ll work alongside experienced engineers in software, product, data, growth and operations, on projects that impact millions of users. At Fever, Software Engineers have a high level of ownership. That means you will be involved end-to-end, from understanding the problem and designing the solution, to coding, deploying to production and monitoring performance.
As a Software Engineer at Fever, you will have real ownership from day one. Engineers are responsible end-to-end: understanding the problem, designing the solution, implementing it, deploying it to production and monitoring its performance.
We build scalable systems using a distributed services architecture, applying best practices such as Domain-Driven Design and clean architecture principles.
While this is a graduate program, you will be working with modern production systems and technologies used at scale.
Our core stack includes:
We focus on building reliable, scalable software used by millions of users worldwide.
