At Ultralytics, we relentlessly drive innovation in AI, building the world's leading YOLO models. We're looking for passionate individuals obsessed with AI, eager to make a global impact, and ready to excel in a dynamic, high-energy environment. Join our team and help shape the future of AI.

? Location and Legalities

This full-time Backend Web Developer position is based onsite in our brand-new Ultralytics office in London, UK. Applicants must have legal authorization to work in the UK, as Ultralytics does not provide visa sponsorship.

? What You'll Do

As a Backend Web Developer at Ultralytics, you will be the architect behind the scalable, high-performance services that power Ultralytics HUB. You will build the backbone that supports our global community in training and deploying state-of-the-art computer vision models. Your key responsibilities will include:

* Designing, building, and maintaining robust APIs using Python and FastAPI. These APIs are critical for managing user authentication, datasets, model training, and our inference API.
* Managing and optimizing our NoSQL databases (MongoDB) and caching layers (Redis) to ensure low latency and high availability for all HUB services.
* Developing and maintaining our cloud infrastructure on Google Cloud Platform (GCP) using Terraform for Infrastructure as Code.
* Deploying and scaling applications using containerization with Docker and serverless platforms like Google Cloud Run.
* Implementing and managing our CI/CD pipelines with GitHub Actions to automate testing and deployment, ensuring rapid and reliable releases.
* Integrating with third-party services for authentication, such as Clerk, and other essential functionalities.
* Collaborating closely with frontend and AI research teams to deliver seamless, end-to-end features for our cutting-edge AI models.

?️ Skills and Experience

* 5+ years of backend development experience, with a strong portfolio of building scalable, production-grade web services.
* Expert-level proficiency in Python and significant experience with modern web frameworks like FastAPI or Django.
* Hands-on experience with NoSQL databases, specifically MongoDB, and in-memory data stores like Redis.
* Deep understanding of containerization with Docker and orchestration with Kubernetes.
* Proven experience with major cloud platforms (GCP is a strong plus) and serverless architectures like Cloud Run.
* Proficiency with Infrastructure as Code (Terraform) and building automated CI/CD pipelines using tools like GitHub Actions.
* Familiarity with modern authentication and authorization mechanisms; experience with services like Clerk is a bonus.
* Experience working in an AI/ML environment and understanding the lifecycle of training and deploying models like Ultralytics YOLO11 is highly desirable.
* Exceptional problem-solving abilities and a track record of thriving in a fast-paced, high-intensity startup culture.

? Cultural Fit - Intensity Required

Ultralytics is not your typical workplace; this is a high-pressure startup environment demanding extraordinary dedication, relentless hustle, and an insatiable hunger for excellence. Our team works exceptionally long hours. We expect you to thrive under intense pressure, embrace extreme accountability, and possess an unstoppable drive to succeed at any cost. If you seek comfort, routine, or a balanced lifestyle, this is not the place for you. Only those truly excited about diving headfirst into the grind, fully committed to shaping the future of AI, should apply.

? Compensation and Benefits

* Competitive Salary: Highly competitive based on experience.
* Startup Equity: Participate directly in our company's growth and success.
* Hybrid Flexibility: 3 days per week in our brand-new office - 2 days remote.
* Generous Time Off: 24 days vacation, your birthday off, plus local holidays.
* Flexible Hours: Tailor your working hours to suit your productivity.
* Tech: Engage with cutting-edge AI projects.
