Opiniion is a SaaS, AI-first company reshaping how businesses understand and act on customer feedback. We are looking for a Staff Engineer, Frontend to lead through hands-on technical execution while raising the bar for frontend architecture, performance, and product quality across the platform. This role is built for someone who can ship polished, high-trust user experiences, coach other engineers through strong technical judgment, and help establish durable frontend patterns as Opiniion scales.

You will partner closely with the Staff Software Architect and cross-functional engineering teammates to guide frontend standards across both the current product and the next-generation platform now being built in parallel. Success in this role means balancing delivery with long-term maintainability: making thoughtful architecture decisions, improving developer ergonomics, and ensuring the frontend experience stays fast, accessible, and resilient as new AI-powered product capabilities are introduced.

• Own day-to-day frontend architecture governance within the broader technical direction set by the Staff Software Architect, escalating cross-cutting decisions when needed.
• Write high-quality, production-grade frontend code as an individual contributor, not only as a reviewer or advisor.
• Mentor engineers through code reviews, pairing, design feedback, and practical technical guidance that improves the overall engineering bar.
• Define and reinforce frontend standards for component architecture, state management, performance, testing, accessibility, and maintainability.
• Partner with product, design, and engineering teammates to turn requirements into polished user experiences that are intuitive, reliable, and scalable.
• Balance ongoing contributions to the current platform with frontend development for the next-generation platform, helping teams decide what to carry forward versus rebuild.
• Design and ship AI-capable frontend experiences, including chat interfaces, streaming responses, intelligent workflows, or other agentic interaction patterns where appropriate.
• Identify and resolve performance, accessibility, and reliability issues across the frontend stack, with a strong bias toward measurable improvements.
• Contribute to design reviews and technical planning so frontend decisions stay aligned with broader platform architecture and business goals.
• Help shape best practices for deployment, observability, and release quality as they relate to frontend systems.
• Use AI tools thoughtfully to improve speed and quality while applying sound engineering judgment and maintaining a high bar for user experience.

• Significant professional experience in frontend software development, typically 10+ years, with meaningful time operating at a staff, principal, or similarly senior technical level.
• Deep expertise in modern frontend development using React and TypeScript in production SaaS applications.
• Strong command of component architecture, design systems, frontend state management, and maintainable UI patterns at scale.
• Proven experience shipping performant, accessible, production-grade web experiences and improving frontend quality across a team or platform.
• Experience integrating backend APIs and handling asynchronous, real-time, or streaming data in the user interface.
• Demonstrated experience mentoring engineers and influencing technical direction without relying on formal people-management authority.
• Strong understanding of testing strategies for frontend systems, including unit, integration, and end-to-end approaches.
• Experience introducing or supporting AI/LLM-powered product experiences in production, not only prototypes.
• Clear written and verbal communication skills, with the ability to explain tradeoffs and align cross-functional partners.
• A pragmatic, ownership-oriented approach and a strong bias for action in a fast-moving environment.

• Experience with design system ownership or large-scale component-library stewardship.
• Experience with performance tuning, frontend observability, and release reliability in complex SaaS products.
• Experience supporting multi-country compliance requirements such as accessibility, privacy, or regional data expectations that affect frontend delivery.
• Background in high-growth SaaS environments, product rebuilds, or post-acquisition platform consolidation.
• Experience with GraphQL, modern build tooling, and advanced frontend patterns for streaming or AI-assisted interfaces.
