We're looking for a hands-on Senior AI Engineer to provide technical leadership within our Generative AI team.
This role is designed for engineers who enjoy combining deep hands-on development with technical leadership. You'll drive technical decisions, shape solution architecture, mentor engineers, and help define engineering best practices while remaining actively involved in designing and building production-grade AI solutions.
Working closely with customers and multidisciplinary teams, you'll help transform complex business challenges into scalable AI systems that deliver measurable business value.
What You'll Do:
Lead the technical design and delivery of end-to-end GenAI solutions, from architecture through production deployment.
Design, build and maintain production-grade AI applications and backend services using Python.
Develop LLM-powered solutions, including retrieval-based architectures, AI agents and orchestration workflows.
Drive architecture decisions for prompt engineering, retrieval pipelines and model evaluation.
Translate business requirements into scalable AI architectures and technical solutions.
Provide technical leadership through design reviews, code reviews and engineering mentorship.
Contribute to engineering standards, best practices and technical excellence across projects.

This is a software engineering role. You'll build and operate the backbone of Fiverr's data platform: distributed pipelines, warehouse infrastructure, and production services processing billions of events, each of which believes it is the most important one. If you think of yourself as an engineer first who happens to work with data, read on. Join our dynamic Data department as a Senior Data Engineer, where you'll play a pivotal role in launching a critical new data product. This is an opportunity to elevate our engineering rigor and deliver innovative solutions for the world's most popular freelance marketplace, tackling complex challenges in distributed data systems and backend engineering. This is not an analytics role: you won't be building dashboards, you'll be building the systems dashboards depend on and never thank.


What am I going to do?:

* Architect and design robust schemas, ensuring scalability and performance. Bonus points if they still make sense to you at 2am during an incident.
* Build production-ready features end to end: data pipelines, backend services, and user-facing elements when needed. Your center of gravity is the backend and data systems.
* Orchestrate and optimize data pipelines, guaranteeing reliable and timely data delivery. You know the difference between a DAG that is elegant and one that is a cry for help.
* Provide technical leadership to enhance software engineering standards across the team, mentoring other developers.
* Treat performance and cloud cost as first-class design constraints across storage, compute, and pipelines.
* Collaborate daily with engineers, analysts, and business stakeholders, who all speak slightly different dialects of data. You will be fluent in all of them.

Equal opportunities:
At Fiverr, we know that talent has no single face. We welcome talent from everywhere and everyone because it makes everything we build better. Need accommodations? Just ask. And if this role excites you but you don't tick every box, apply anyway. The best people rarely fit the mold exactly.
