Full Stack Engineer • Senior

Who you are

You have a strong background in full-stack development, with expertise in JavaScript, React, and Node.js — you've built scalable applications and understand the intricacies of both frontend and backend technologies. Your experience in Agile environments has equipped you with the ability to adapt quickly and work collaboratively with cross-functional teams.

You thrive in complex technical challenges — your problem-solving skills have been honed through years of experience in developing efficient software systems that handle high traffic and demand. You are comfortable working with distributed systems and have a keen understanding of performance optimization.

You are a team player who values communication and collaboration — you enjoy sharing knowledge with your peers and mentoring junior developers. Your ability to articulate technical concepts clearly makes you an asset in any team setting.

Desirable

Experience with cloud technologies and microservices architecture is a plus — you understand how to leverage these tools to enhance application performance and scalability. Familiarity with advertising technologies or media planning platforms would be beneficial but is not required.

What you'll do

As a Senior Fullstack Engineer at Equativ, you will join a dynamic R&D team focused on building and enhancing our Demand products. You will collaborate closely with other developers to design and implement features for our media planning platform, Maestro, ensuring it meets the needs of digital advertisers and data curators.

You will be responsible for writing clean, maintainable code and conducting code reviews to uphold high standards of quality. Your role will involve troubleshooting and debugging issues as they arise, ensuring that our systems remain efficient and responsive under heavy load.

You will participate in Agile ceremonies, contributing to sprint planning and retrospectives, and helping to shape the direction of the product through your insights and expertise. Your contributions will directly impact the success of our platform, enabling our customers to achieve their digital business goals.

Equativ provides a collaborative and innovative work environment where you can grow your skills and advance your career. We offer competitive compensation and benefits, along with opportunities for professional development. You will be part of a diverse team of engineers who are passionate about technology and committed to delivering exceptional products.

Join us in Kraków, where you will have the chance to work on cutting-edge technologies and tackle some of the most complex challenges in the advertising industry. We encourage you to apply even if your experience doesn't match every requirement — your enthusiasm and willingness to learn are what matter most.
