Staff Backend Engineer- Agent Experience (AX)
Cloudinary · Israel

Cloudinary is the media experience platform trusted by millions of developers and thousands of companies — from fast-growing startups to the world's largest brands — to power the images and video behind their digital experiences. Something fundamental is changing about who uses that platform. Increasingly, the "developer" calling our APIs isn't a person — it's an agent: an LLM, a coding assistant, an autonomous pipeline acting on a human's behalf. Our Agent Experience (AX) R&D team exists to make Cloudinary the default media layer those agents run on. Our guiding principle is simple: make agentic workflows work flawlessly with no friction. We're a small, fast, high-ownership team, and we're looking for a Senior Backend Engineer to make Cloudinary work for agents — both by building new agent-facing infrastructure and by reshaping our existing platform for a world where the caller is a machine. Some of this is greenfield. Much of it is taking APIs, auth, and SDKs and making them ergonomic, legible, and reliable for agents. It’s a problem the whole industry is still figuring out. You’ll help define what great API design looks like when the caller is not a human developer, but an agent acting on their behalf. What you'll do • Build the surfaces agents call directly: API-first account provisioning, machine-to-machine authentication, scoped credentials, and agent-level identity and attribution. • Own our MCP (Model Context Protocol) servers and an agent-first CLI — let coding agents and LLMs discover and invoke Cloudinary reliably, engineered for agentic callers: token-efficient tool schemas, machine-parseable output, and loud, actionable failures instead of silent ones. • Harden the agent media path — make upload and core media operations reliable for non-human callers, eliminating the ambiguity and silent-failure modes that cause agents to drop off mid-task. • Make agent behavior measurable — partner on the instrumentation, signals, and attribution that tell us whether agents are succeeding. • Work across a polyglot backend — Node.js/TypeScript for the agent tooling layer, with Ruby/Rails and Go in the core platform. • Ship, measure, iterate — prototype quickly, dogfood the experience, and represent the agent's perspective in every design decision. Work closely with Product, Ecosystem, and Discoverability across the AX team. About you • 10+ years building and operating production APIs, SDKs and Backend systems and at scale. • Strong in Node.js/TypeScript, and comfortable working in (or quickly ramping on) Ruby/Rails and/or Go. • Deep API and protocol design fundamentals — authentication (OAuth, API keys, scoped permissions), versioning, idempotency, rate limiting, clean contracts. • Genuine curiosity about agents and LLMs and how they're reshaping how software gets built and run. • Solid distributed-systems and cloud instincts (AWS or equivalent). • A bias for ownership in ambiguity — you scope the problem, not just the solution, and you ship. • Strong written communication — it matters more than usual when your consumers are machines and your teammates are distributed. Advantages • Hands-on experience with MCP, LLM tool/function-calling, or building AI-/agent-native products. • Experience building SDKs, CLIs, or developer tools that other engineers depend on. • Background in media, imaging, or video processing/delivery. • Open-source contributions in the agent or developer-tooling ecosystem. Cloudinary is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. #LI-SL1

The team is very small, highly focused, and fully hands on. Why This Role Is Different You will work on a backend system where scale, cost, and correctness all matter at the same time. You will have real architectural ownership, direct customer impact, and the freedom to move fast without heavy process. Few roles offer this combination inside a mature company. What You Will Do Own the Server Side Design, build, and evolve the server side of a moderation platform operating at scale, including: • High throughput async pipelines • Large volumes of images and videos • Multi tenant systems • Cost sensitive ML workloads • Agentic moderation workflows and AI-driven decision systems Ship Fast, Ship Smart Deliver value iteratively with a clear focus on customer and business impact. Move quickly without losing sight of long term architecture and operational quality. Set the Technical Foundation Make architectural decisions that scale over time. Use agentic development and code generation to accelerate delivery, while keeping engineering judgment, technical accountability, and code ownership firmly in human hands. Elevate Quality and Standards Build clean, modular, secure backend systems that are meant to live and evolve. Establish good engineering practices around testing, observability, reliability, and maintainability. Drive Innovation and Practicality Explore new ideas and approaches, but always ground them in real world constraints like latency, cost, and operational complexity. Who We Are Looking For Experienced Backend Engineer 10+ years backend experience owning and delivering production systems. Strong hands on coding skills and confidence working deep in the backend stack. Languages and frameworks do not slow you down. We use Python. Cloud Native Strong experience building and operating cloud based systems, preferably on AWS. Hands on experience with distributed systems, async processing, queues, workflows, and production monitoring. Independent, Collaborative, and Comfortable with Ambiguity You thrive in low-process environments and communicate clearly and take ownership of outcomes, not just implementation. You can step into new domains, work through messy problems, and make fast progress while collaborating effectively with engineers, PMs, and stakeholders across the company. A Great Teammate You value clear communication, trust, humor, and helping build a strong and supportive team culture. #LI-SL1
