Senior Software Engineer II – Frontend (Web Frameworks)

Optro is a leading audit, risk, ESG, and InfoSec platform that has surpassed $300M ARR and is recognized as one of the fastest-growing tech companies in North America. They are seeking a Senior Software Engineer II to join their Web Frameworks team, where the engineer will optimize data access, improve platform functionality, and provide technical leadership while mentoring others.

Responsibilities:

• Optimize Data Access: Work with a team to design solutions and execute on cross-team initiatives to modernize complex UI components and leverage high-performance paginated query APIs
• System Collaboration: Partner closely with Platform, Architecture, and Product teams to align on migration roadmaps and technical execution. Stay aware of what's happening across the engineering organization. Understand how your work connects to and affects other teams, and factor that into your approach
• Technical Leadership: Become a subject matter expert on frontend API access patterns; participate in deep-dive code reviews and provide constructive feedback for continuously improving our API endpoints and frontend integration
• Mentorship: Scale your impact by mentoring engineers, documenting best practices, and helping to define agentic coding standards to streamline frontend modernization while maintaining code quality and stability
• Risk Management: Proactively identify technical debt and migration risks, providing accurate estimations and clear communication to stakeholders throughout the project lifecycle

Requirements:

• Strong Frontend Engineering Skills: Deep expertise in modern frontend frameworks (Ember.js is a significant plus, but we value strong experience in React or Vue as well)
• Familiarity with Modern API Patterns: A strong understanding of modern API standards (e.g., JSON:API), pagination strategies, and complex query builders
• Experience with complex refactors: You've contributed meaningfully to large refactors or migrations, and you understand the patience, coordination, and attention to detail that kind of work requires
• Communication & Influence: Exceptional ability to explain technical trade-offs to non-technical stakeholders and drive consensus across disparate teams
• Genuine Curiosity: You're the kind of person who wants to understand why something works the way it does, not just how to use it. You dig into problems, ask good questions, and aren't satisfied with surface-level answers
