Job description

Who We Are?

Our team is part of a larger group working on the Cloudinary Assets product, a high-scale, distributed system built on cloud infrastructure.

We deliver a solution for both technical and non-technical users, allowing them to manage, deliver, transform, and collaborate on Media assets and their lifecycles seamlessly through API and UI.

We take full ownership of the entire process, from deciding what to build to delivering it.

Our team has the right mix of skills to make both technical and product decisions together, ensuring smooth execution and meaningful impact.

We are a highly collaborative, open, and proactive team, with members based in Poland and Israel. We work primarily in English.

Few words directly from the team lead

I’m looking for a real expert to my team. Someone who can be a mentor to all other backend engineers in my team and also in other teams in the office. Someone who’ll jump head first into our spaghetti Ruby monolith and will help me cut it out into little pieces, extract and bring us into a new era of Go-based services and fast, reliable APIs. I need you to be bold, courageous, accountable and with lots of proactive will to bring innovation. I’ll offer real partnership and enablement at all functions.

What You’ll Do?

• Be a Central Figure in the Team– Serve as the go‑to expert on everything related to the team’s services and infrastructure. Work closely with product managers. Learn and be able to reason about the existing code base on demand, deriving insights quickly and managing context switches effectively.
• Deliver Solutions with Impact & Efficiency– Stay focused on business goals and customer delight. Ensure we deliver features that move the needle and are implemented efficiently and iteratively.
• Maintain High Code Quality & Architecture– Collaborate with developers to uphold high coding standards and work with our architects’ forum to ensure solutions are scalable and aligned with our platform vision. Utilize code generation tools for a larger impact.
• Drive Innovation– Identify areas for improvement and propose meaningful enhancements. Acknowledge customer feedback and incorporate your ideas to refine our solutions.

What type of person are we looking for?

• Experienced Developer– 10+ years of experience as a Backend Engineer, with a proven track record of delivering high-quality, scalable solutions.
• Hands‑On Developer– Comfortable coding in multiple languages (Ruby, Go, Node). Experience working with Generative AI technologies (GPT, Copilot, Cursor) is a plus.
• Cloud Savvy– Strong hands‑on experience with AWS (or equivalent). Expertise in high-scale, distributed cloud architectures.
• Business‑Focused– Driven by delivery and impact rather than rigid role definitions. You think beyond just backend development and consider the bigger product and business picture.
• Collaborative & Team‑Oriented– Build strong relationships across disciplines, working closely with product managers, architects, and team leads to ensure impactful execution.
• Adaptable & Resilient– The team frequently shifts priorities based on urgency, requiring a high level of context‑switching. You should be comfortable diving deep into complex codebases and working beyond your immediate scope.
• Active & Engaged– We operate in a fast‑changing environment, with active engagement in meetings and Slack.
• An Amazing Teammate– You enjoy communication, humor, and forming real friendships with teammates, creating a fun and comfortable work environment.

If you’re excited by tackling challenges at scale and shaping the future of media management, we’d love to talk!
