We are seeking an experienced Senior Staff Backend Engineer for our new generation Digital Vault (DV) SaaS product. You will be responsible for building core SaaS offerings on top of an AWS serverless stack using Python, CDK, and other cloud technologies. You will work with a collaborative team of developers, architects, DevOps, and QA to produce top-notch services from planning through production.
Your Impact
Build and maintain core SaaS products using an AWS serverless stack, Python, and CDK.
Collaborate within an agile team through the entire development lifecycle, including architecture, design, testing, and automation.
Work with developers, architects, DevOps, and QA members to produce high-quality services and maintain high standards.
Engage in all aspects of the development lifecycle, including handling production-care and responding to customer feedback.

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 our 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.

Our team is building a new product within Cloudinary, focused on large scale visual moderation.

It is a fast moving, high impact effort that is already attracting interest from major customers.

We operate like a small startup inside Cloudinary, which means:

Full independence in technical and product decisions.

Freedom to build things the way we want.

The backing and stability of a well established, successful company.

Strong people first culture with genuinely great teammates.

We own the full development lifecycle, from deciding what to build to how we build, ship, and operate it. The team is very small, highly focused, and fully hands on.

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.

The Accounts team owns some of the most critical infrastructure at the core of our platform.
We are responsible for identity, access, and account management across all our products - from authentication and fine-grained authorization to account provisioning and enterprise integrations.

Lead solutions for the business application platform layer with robustness, security, and monitoring in mind.

Become a company-wide focal point for identity, access, and account-management knowledge.

Lead by example, mentor peers, and ensure high standards of code quality.

Work with product managers and business partners to frame problems within the business and product context.

We are 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 wholl 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. Ill offer real partnership and enablement at all functions.


What Youll Do?

Be a Central Figure in the Team - Serve as the go-to expert on everything related to the teams 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.
