О компании и продукте

• Sumsub is the first AI-powered trust infrastructure for compliance operations at scale. It connects identity and business verification, fraud prevention, transaction monitoring, and risk workflows, helping teams reduce manual work and enter new markets.
• Trusted by over 4,000 clients across financial services, crypto, mobility, trading, marketplaces, education, and iGaming, including Bybit, Bitpanda, Wirex, Avis, Vodafone, Duolingo, Kaizen Gaming, and Bancaribe.
• Sumsub is recognized as a Great Place To Work® in the US and rated 4.3 out of 5 on Glassdoor. Our 1,000+ people around the world back it up, too: 92% are proud to be Sumsubers, and 90% say their work is interesting and challenging.
• Now we are looking for an experienced Machine Learning Engineer to build, deploy, and own end-to-end ML solutions that combat sophisticated fraud, deepfakes, and identity theft. This role is an exciting opportunity to have true product autonomy, see your models protect millions of users in real time, and scale a platform that handles millions of verifications a day .

Задачи

• Own the full ML lifecycle: from data collection, labeling, and training through optimization, production rollout, and ongoing quality assessment
• Train CV/ML models to detect deepfakes, segment documents, and uncover complex anomaly patterns in real time
• Balance research and speed: know when to build a full deep learning model and when to ship a simple, clever heuristic that solves the problem fast
• Serve models efficiently with FastAPI and PyTorch, integrating cleanly with our high-load Java backend
• Build and monitor ML pipelines and dashboards with Airflow, ClickHouse, and Superset so models stay reliable under heavy load

Требования

• 4+ years of experience as an ML / CV Engineer in fast-paced, high-load product environments
• Strong background in deep learning frameworks (PyTorch is our go-to) and solid production-grade engineering skills
• Fluent with the data side of the work: labeling, collection, and navigating the data space to decide what to include, what to leave out, and how those choices affect training
• Solid grasp of how the training distribution relates to what the model sees in production — sampling, skew, and shift, and how to catch it before it bites
• Familiar with current research, the latest baselines, and modern architectures
• An autonomous product owner: capable of taking an idea from inception to implementation under the pressure of a competitive market
• A proactive communicator: you easily align with PMs and backend teams, and you don't go quiet if something breaks - you find the solution

Будет плюсом

• Experience standing up model serving and the infra around it (Triton or FastAPI, queues, autoscaling, monitoring)
• Comfortable designing and reading online experiments / A-B tests
• Experience with big data and stream processing tools (Kafka, Flink, Trino, or ClickHouse)

Условия
