About the role
About Obvio AI
Each year, more than 40,000 people in the U.S. leave home and never make it back due to traffic crashes. At Obvio, we believe these deaths are preventable. We deploy solar-powered, AI-assisted cameras to enforce traffic laws where pedestrians are most vulnerable—automating enforcement in ways that traditional systems cannot. Our approach has already led to a 50% reduction in reckless driving in early partner cities.
Founded by the team behind Motive's AI dashcam and backed by Bain Capital Ventures and Khosla Ventures, we are building the intelligence layer for safer streets globally.
About the Role
We're seeking a Senior Software Engineer to lead the design and scaling of backend infrastructure that powers our annotation workflows. These systems sit at the core of our machine learning feedback loops and operational pipelines. You’ll work across product, ML, and ops teams to build resilient, observable, and secure systems that translate ambiguous requirements into elegant software.
What You’ll Do
Design and scale distributed systems that support high-throughput data review and annotation pipelines
Build systems that prioritize performance and reliability under real-world load
Apply strong security and privacy practices, including fine-grained access control, secure data handling, and auditable workflows
Translate messy, cross-functional requirements into clean APIs and backend abstractions
Collaborate with product, ML, and operations to streamline efficiency and feedback loops
Lead architectural decisions, conduct design reviews, and elevate engineering quality across the team
Mentor engineers to improve system ownership, technical judgment, and long-term thinking
What We’re Looking For
8+ years of backend engineering experience
Proven ability to design and scale distributed systems
Operational rigor: you build systems with observability, alerting, and failure recovery in mind
Strong understanding of security principles, including least privilege, secure transport/storage, and compliance awareness
Ability to synthesize broad, sometimes ambiguous input into clean design and interfaces
Experience mentoring engineers and guiding architectural direction on complex projects
Bonus Points
Familiarity with human-in-the-loop systems, labeling tools, or ML data pipelines
