Develop and optimize APIs, data models, and domain-specific workflows supporting machine learning and LLM observability use cases.
Build reusable, high-performance frontend components and data visualization interfaces that enhance user experience and system interpretability.
Participate in architectural decisions across frontend, backend, and data layers in collaboration with product, design, and engineering teams.
Contribute to the development of AI-driven features, including in-house agents and experimental ML/LLM tooling.
Research and implement advanced visualization techniques and scalable approaches for handling large-scale AI evaluation data.
Engage in code reviews, technical documentation, and cross-functional collaboration to ensure quality and alignment across the stack.

Requirements:

5+ years of frontend or fullstack engineering experience, with strong expertise in React and TypeScript for building user-facing applications.
Proven experience designing and operating scalable SaaS systems or complex distributed applications in production environments.
Strong understanding of APIs, system design, and backend integration, with exposure to Python and/or other backend technologies (Go a plus).
Demonstrated ability to debug and reason through complex technical systems in collaborative engineering environments.
Strong product mindset with a focus on user experience, performance, and delivering end-to-end features.
Genuine interest in AI, LLMs, and modern machine learning systems, with a desire to stay current in the evolving ecosystem.
Excellent collaboration and communication skills, with the ability to work effectively across engineering, product, and design teams.

Benefits:

Competitive compensation package including base salary ($125,000 – $225,000) and equity opportunities.
Comprehensive health, dental, and vision insurance coverage.
Unlimited paid time off and generous parental leave policies.
401(k) retirement savings plan.
Monthly work-from-home stipend supporting co-working space, internet, and home office needs.
Strong focus on learning, development, and exposure to cutting-edge AI technologies.
