We are now a team of 25 passionate and ambitious people based between Paris, Barcelona and Boston and have grown revenue 5x in 2025. We aim to repeat this trajectory in 2026. The scale-up phase is fully underway. 🚀 About the role : This is a foundational role. You will be our first dedicated DevOps/Infrastructure Engineer and will take full ownership of everything related to cloud infrastructure, deployments, reliability, and scaling . Our engineering team is made up of 7 people, operates with intensity, and moves fast. Rapid iteration is one of our biggest advantages. Over the past two years, we’ve built a tremendous amount, but the surface area ahead of us is even larger as we scale usage, models, and automation. You will play a key role in keeping our platform fast, reliable, and ahead of the curve. This role goes beyond DevOps. You will also contribute at the LLM layer: running evaluations, experimenting with models, improving latency, optimizing costs, and helping shape how our AI systems operate at scale. If you enjoy working at the intersection of infrastructure, backend systems, and AI, this is exactly the kind of role where you’ll thrive. What You Will Own : Infrastructure & Platform : All cloud infrastructure across AWS, GCP, and Azure. Kubernetes cluster management, scaling, upgrades, and security. CI/CD pipelines (GitHub Actions) and deployment systems. Observability, monitoring, logging, alerting, and reliability practices. Incident response, on-call rotation, and uptime improvements. Cost optimization and infra-level performance tuning. Security best practices, IAM, secrets, policies, and overall infra hygiene. Backend & Data Systems : High-scale PostgreSQL (large DB, indexes, performance tuning). Redis and Sidekiq pipelines, queue scaling, job parallelization. API performance and throughput. AI / LLM Systems : Manage and optimize LLM deployments across cloud providers. Improve latency, reliability, and cost through routing and system architecture. Help build and maintain eval pipelines and A/B tests. Contribute directly at the app level (prompts, agents, routing). Support or prototype self-hosted model experiments (optional but valuable). The Ideal You : You have 8+ years of experience in DevOps / infrastructure roles, ideally in fast-paced SaaS or startup environments. You’ve scaled production systems before and know how systems behave under real load. You’re equally comfortable deep in Kubernetes or writing Ruby/Python for a quick script, tool or LLM eval. You care about reliability, speed and pragmatism. You enjoy working on AI systems and have hands-on experience with LLM-powered applications. Your toolkit includes: Kubernetes, Docker AWS, Azure, GCP (strong in at least 2) GitHub Actions CI/CD PostgreSQL, Redis, Sidekiq LLM APIs (OpenAI, Azure, Anthropic; self-hosted a plus) Terraform or similar IaC Strong coding ability to contribute across the stack The Alternative You : If you're earlier in your career but have strong infrastructure experience and clear upside, and you can reasonably grow into the full scope within 2 to 3 years, feel free to reach out. Raw talent is welcome, but depth of experience scaling systems is a big plus here. Why Yuma ?

About Yuma AI: Yuma is building a next-generation orchestration platform that deploys autonomous AI agents dedicated to customer support in e-commerce.

We are now a team of 25 passionate and ambitious people based between Paris, Barcelona and Boston and have grown revenue 5x in 2025. We aim to repeat this trajectory in 2026. The scale-up phase is fully underway. 🚀 Role Overview We remain a small team of 5 engineers, but we are intense and we move very quickly! Fast iteration is key. In the past 2 years since Yuma’s founding, we’ve built a lot, but there is still much more to do! We operate at startup speed and handle everything: product iterations, A/B testing, LLM research, AI Agents pipeline, new feature development, performance optimizations, and more. We are intensely focused on delivering value to our users and on product excellence. That is the only thing that matters. Our backend is a standard Ruby on Rails API powered by PostgreSQL, Redis, and Sidekiq. Our frontend uses Next.js and React. We already handle a significant load, ingesting and processing millions of support tickets per month and millions of e-commerce data points per day. We are definitely not a 9-to-5 team, and we are heavily committed to delivering excellence throughout our craft. The ideal You: You have led and built multiple large Rails applications, and you always strive for excellence. You are pragmatic, making the right trade-offs that favor speed of iteration while maintaining high product quality. You are driven by delivering the best experience and value to your users. You might have a preference for working on backend projects, but you aren't afraid of frontend work. Rails has no secrets for you. Recent experience playing with LLMs is now mandatory, and you have already adopted AI in your day-to-day tasks. Building with LLMs and managing non-deterministic output is not scary to you. If you are relentless, deeply caring about delivering value & ownership, and looking to join an early, hard-working team, we want you 👈. We are seeking someone who is looking to embrace a new challenge and commit to it 100%. Your diploma doesn't matter to us; we only care about your skills, your sense of ownership, and drive. The Alternative You: If you’re still junior, but the description above sounds like the person you aim to become in the next 3 years, don’t be shy: there’s always space for raw talent at Yuma. Dont' be shy, apply! :) OUR CULTURE Please, if you are considering applying, first read our culture page: <u>https://www.notion.so/yuma-ai/Yuma-s-Culture-5b0e15f1334242ce8a62daab9f2038a1?pvs=4</u>
