Senior Artificial Intelligence/Machine Learning Engineer

About the Position

Ciklum is looking for a Senior Artificial Intelligence/Machine Learning Engineer to join our team in Argentina. We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts, and product owners, we engineer technology that redefines industries and shapes the way people live.

As a Senior Artificial Intelligence/Machine Learning Engineer, you'll become a part of a cross-functional development team engineering the experience of tomorrow.

Project Description: Creates the quality bar every AI system must pass - golden datasets, eval harnesses, pass thresholds - before launch and continuously in production. Defines what “good enough to ship” means, and measures it monthly for the scoreboard.

Responsibilities

• Build the central eval harness and templates every pod uses; hub-and-spoke: central standards, pod-written tests
• Create golden datasets with business and clinical reviewers, including safety and medical-accuracy suites
• Set and defend pass thresholds; audit pod evals; report eval pass rates and incidents monthly
• Stand up production monitoring for drift and regression with the pipeline engineer

Requirements

• 4+ years in ML/LLM evaluation, QA engineering for AI systems, or applied research engineering
• Hands-on with eval frameworks, LLM-as-judge patterns and their failure modes, statistical rigor on small samples
• Independent spine: the team shipping a thing does not set its own pass bar

Nice to Have

• Healthcare or safety-critical evaluation experience
• Red-teaming background

We Offer

• Care: Your mental and physical health is our priority. We ensure comprehensive company-paid medical insurance and mental health programs, 5 undocumented sick-leave days per year.
• Tailored education path: Boost your skills and knowledge with our regular internal events (meetups, conferences, workshops), Udemy license, language courses, and company-paid certifications.
• Growth environment: Share your experience and level up your expertise with a community of skilled professionals, locally and globally.
• Long-term employment: 20 working-days paid vacation and local bank holidays.
• Flexibility: 100% remote work mode.
• Opportunities: We value our specialists and always find the best options for them. Our Internal Mobility Program helps change a project if needed to help you grow, excel professionally, and fulfill your potential.
• Global impact: Work on large-scale projects that redefine industries with international and fast-growing clients.
• Welcoming environment: Feel empowered with a friendly team, open-door policy, informal atmosphere within the company, and regular team-building events.
