About FERO

FERO is reinventing checkout for eCommerce.

We build high-performance, adaptive checkout experiences that help merchants increase conversion and revenue.

Backed by top-tier VCs, we’re building from Madrid with a strong focus on performance, data, and real impact.

About the role

We’re looking for a Platform Engineer to join our Engineering team.

You’ll help build and scale the backend services and platform infrastructure that power FERO’s products, including the analytics services behind our dashboards. Working closely with the engineering team, you’ll develop reliable, scalable systems, build robust APIs, and contribute to the evolution of our platform.

This role is ideal for someone who enjoys solving technical challenges, learning new technologies, and working in a fast-paced startup environment.

What you’ll do

• Build and maintain backend services, primarily in Python.
• Develop and maintain robust REST APIs.
• Design scalable and reliable backend systems.
• Work with analytics data, building and optimizing services that query ClickHouse and power our dashboards.
• Collaborate with engineers across different teams to deliver platform improvements.
• Improve system performance, reliability, and scalability.
• Participate in technical discussions, code reviews, and architectural decisions.
• Contribute to improving our engineering practices and tooling.

What you’ll bring

• Professional experience with Python.
• Experience with at least one backend framework (FastAPI, Django, or Spring Boot).
• Experience building and maintaining REST APIs.
• Experience designing scalable backend systems.
• Strong backend engineering fundamentals.
• Ability to work collaboratively within an engineering team.

Good to Have

• Experience with Java.
• Experience with ClickHouse or other analytical/columnar databases.
• Experience with AWS.
• Experience with Docker and Kubernetes.
• Experience with event streaming or message queues (Kafka is a plus).
• Experience with CI/CD pipelines.
• Experience with observability and monitoring tools.

Who you are

• You’ve ideally worked in smaller teams.
• You’re excited to learn new frameworks, tools, and technologies.
• You like being close to the impact of your work. At our size, what you build reaches production and customers fast.
• You’re happy wearing more than one hat when needed. In a team our size, ownership doesn’t stop at a narrow job description.
• You’re comfortable when priorities shift as we learn. We’d rather ship, iterate, and improve than wait for perfection.

What we offer

• Permanent contract.
• Private health insurance (partially covered).
• Hybrid work (3 days office / 2 remote).
• Office in a central location in Madrid.
• Real growth opportunities.
• High-impact, collaborative environment.
