Senior Software Development Lead

Role Overview

• Build rapid prototypes and proof-of-concepts that turn experiment results and AI research into interactive, testable demos that stakeholders and users can try
• Create frontend interfaces for production AI solutions review dashboards, configuration screens, monitoring views, approval workflows
• Build integration layers between AI systems and existing infrastructure APIs, data connectors, authentication flows, third-party service integrations
• Develop small-scale testing environments where new features can be validated with real users before committing to full development
• Instrument prototypes to capture usage data and feedback support user validation experiments with measurable data
• Work closely with AI/ML engineers to wrap agent workflows in usable, intuitive interfaces
• Support the Data Scientist and Quantitative Researcher by building data collection, visualization, and reporting tools when needed
• Build self-serve tools for internal stakeholders dashboards for tracking solution performance, configuration interfaces for managing agent behavior, and reporting tools that reduce dependency on the data team
• Evolve successful prototypes into production-grade internal applications handle the scale, reliability, and maintainability concerns that come with tools people depend on daily
• Build real-time monitoring and observability interfaces that give the team and stakeholders visibility into how AI solutions are performing in production

Requirements

• 6+ years of experience as a full-stack engineer building web applications you’re comfortable owning a feature from database to UI
• Strong frontend skills in React
• you can build clean, functional interfaces quickly without needing a designer for every screen.
• Strong backend fundamentals with NodeJS as the primary server-side runtime. You can stand up a working backend in a day when a prototype needs one. APIs, databases, and authentication are second nature.
• Working knowledge of Python and .NET
• the team's AI and data work is heavily Python-based, and some existing solutions use .NET. You need to be able to read, contribute to, and integrate with code in both languages.
• Experience integrating third-party services and APIs you’ve connected systems together and dealt with the messiness that comes with real-world integrations.
• Comfort with ambiguity and speed you can take a rough idea and figure out the fastest path to a working demo without waiting for a detailed spec.
• Willingness to build fast and throw things away you understand that most prototypes are learning tools, not production features, and you’re okay with that.
• Enough familiarity with AI/ML concepts to work effectively alongside AI engineers and researchers without needing everything translated for you.
• Experience with agile methodologies (Scrum, Kanban, or similar).
• Experience building interfaces for AI-powered products chat UIs, content generation tools, review or approval workflows, dashboards for AI system monitoring.
• Deep experience with Python or .NET beyond the baseline
• e.g., building your own services or pipelines in these languages, not just integrating with them.
• Experience building production-grade internal tools or platforms not just prototypes, but applications that teams rely on daily.
• Experience with real-time data visualization or monitoring dashboards.
• Experience with rapid prototyping tools or frameworks that accelerate demo-building.
• Background in user research or usability testing you know what to watch for when someone tries your prototype for the first time.
• Experience building self-serve analytics or configuration tools for non-technical users
