Who You Are

We are looking for a Senior Data Scientist to join our Verve Marketplace Data Science team. You will work across data science, backend engineering, and MLOps, deploying models, optimizing real-time performance, and managing large-scale data pipelines. This hands-on role covers the full lifecycle, from design and deployment to monitoring and optimization, with a direct impact on revenue and product performance.

What You Will Do

• Design, implement, and maintain high-performance backend systems for AI-powered products

• Deploy, integrate, and optimize machine learning models into production by building gRPC/RESTful APIs and microservices for consuming model predictions

• Automate model training and deployment with Kubernetes, Helm charts, and CI/CD pipelines to streamline the path from development to production

• Build and optimize systems to ensure minimal delay between input and output, often measured in milliseconds

• Design distributed systems to handle large AI workloads and high-throughput inference, balancing latency and throughput as traffic grows

• Develop pipelines and templates for model training, deployment, monitoring, and iteration

• Continuously monitor deployed models to ensure they remain safe, secure, and performant in live environments

• Manage and serve features through centralized repositories for consistent use in both training and production

• Ensure real-time availability of features for low-latency predictions

• Guide and mentor engineers to strengthen backend development and machine learning expertise

• Act as an MLOps specialist, collaborating with product managers, data scientists, and other stakeholders to provide actionable recommendations

What You Will Bring

A strong foundation in software engineering, combined with specialized knowledge in machine learning systems, is essential.

• 3–5+ years of professional software engineering experience, with 3+ years focused on building and deploying ML systems in production

• High proficiency in Python; experience with compiled languages (Go, Java, Rust, or C++) for high-performance, low-latency backend services

• Hands-on experience with ML libraries such as PyTorch, TensorFlow, and scikit-learn

• Proven ability to build, deploy, and maintain scalable backend systems, including RESTful APIs and microservices (FastAPI, Flask, gRPC)

• Expertise in MLOps, including Docker, Kubernetes, CI/CD (Jenkins, GitLab CI, GitHub Actions), and Infrastructure as Code (Terraform, Ansible)

• Experience with model serving platforms (NVIDIA Triton, TensorFlow Serving, Seldon Core) and optimization techniques such as quantization and pruning

• Practical experience with feature stores, open-source (e.g., Feast) or commercial (e.g., Tecton, SageMaker), for training and real-time inference

• Proficiency in at least one major cloud platform (AWS, GCP, or Azure) and related AI/ML services (Amazon SageMaker, Google Vertex AI, Azure Machine Learning)

• Bachelor’s or Master’s degree in Computer Science, Software Engineering, Statistics, or a related quantitative field

What We Offer

• Be part of a multicultural team that is bringing advertising to the next level

• You will learn and evolve in an empowering environment characterized by entrepreneurial actions

• Responsibility, independence, and an opportunity to participate in projects that have a significant impact on Verve’s success

• 3 Wellness days per year (in Q1, Q2 & Q3) and Employee Assistance Program through Nilo Health to help you maintain your well-being

• Enhance your professional skills with a yearly training budget and improve your language skills through German and/or English classes

• Work and Travel Program (monthly raffle after 2 years of employment) 

• We are eager to build a great team together and we appreciate your help through our Employee Referral Bonus 

• Align your interests with the company's success and take part in our Employee Shares Purchase Plan
