Job description

• As part of the Platform Engineering team, you will help build DataVisor’s next-generation machine learning platform, combining our proprietary unsupervised machine learning technology with supervised machine learning algorithms to power real-time fraud detection at scale
• As fraud attacks become increasingly sophisticated, real-time detection is more critical than ever
• Our platform team is responsible for designing and developing the architecture that makes scalable, real-time detection possible, including streaming systems, storage layers, and training pipelines that support our core detection capabilities
• We are looking for a creative, hands-on engineering leader to help expand our streaming and database systems, improve our core detection algorithms, and automate the end-to-end training process
• This role is ideal for someone who enjoys solving complex distributed systems problems, mentoring engineers, and driving technical execution in a high-impact environment
• Join us as we continue to push the boundaries of fraud detection, machine learning infrastructure, and large-scale data processing
• Own the technical direction of the real-time detection platform, including streaming, storage, and the training pipelines that support it
• Translate product and engineering roadmaps into clear technical plans, milestones, and execution priorities
• Proactively identify technical risks, dependencies, and trade-offs before they impact delivery
• Lead design and architecture reviews, make technical trade-off decisions, and document the reasoning behind key decisions
• Stay hands-on by coding, reviewing code, debugging issues, and supporting the team during production incidents
• Mentor engineers and raise the bar for system design, code quality, operational excellence, and technical execution
• Own the operational health of the platform, including alert quality, on-call load, incident follow-through, and root-cause prevention
• Partner directly with Product, TAM, and customer-facing teams on customer-impacting issues, ensuring clear impact assessment, prioritization, ownership, and next steps
• Define how the team uses AI agents and AI-assisted tools in engineering workflows, including verification standards and safe usage practices
• Build, evaluate, and improve LLM- and agent-assisted tools for engineering and operations use cases, such as triage, root-cause analysis, alert summarization, and evaluation harnesses
