Senior Frontend Engineer

Quant Link is a financial technology company building data and analytics tools for public equity markets. We use modern software engineering, machine learning, and quantitative research to help investors better understand how companies and stocks have behaved historically under different conditions.

Our platform focuses on:

• Organizing and analyzing large sets of technical, fundamental, and price-based data
• Providing transparent, evidence-based analytics and tools
• Supporting investors and professionals in making more informed, data-driven decisions

As an early-stage company, we work in a focused, collaborative environment where people can take real ownership of their projects and see their work used in production.

We are looking for a Senior Frontend Engineer to lead the development of our user-facing applications. This is a full‑time role based in Minneapolis, MN, with a hybrid work arrangement. You will own the frontend experience across web and mobile, with a focus on building intuitive, high‑performance interfaces for complex financial data. You'll work directly with the founder and collaborate closely with product, data science, and backend engineering to deliver a best‑in‑class user experience.

• Own and drive the frontend architecture using Next.js, Type Script, and React
• Build responsive, polished experiences across desktop and mobile that feel native and performant
• Design and implement sophisticated data visualizations that make large financial datasets intuitive and actionable
• Collaborate with backend engineers to design clean API contracts and efficient data fetching patterns
• Champion frontend best practices: component architecture, state management, accessibility, and performance optimization
• Manage deployments and CI/CD workflows via Vercel
• Write well‑tested, maintainable code with a focus on reliability and developer experience
• Partner with product and design to translate requirements into delightful user experiences
• Help shape engineering standards, architecture decisions, and team culture

• 5+ years of professional frontend engineering experience shipping and operating production applications
• Deep expertise in Next.js, Type Script, and React
• Strong track record building responsive, mobile‑first web applications
• Proven experience designing and implementing complex data visualizations (charts, tables, grids) for data‑heavy applications
• Experience with frontend performance optimization and Core Web Vitals
• Familiarity with Vercel or similar deployment platforms and CI/CD workflows
• Strong eye for design, UX patterns, and attention to detail
• Ability to work in Minneapolis with a hybrid schedule (3 days/week in office)
• Excellent communication skills and comfort working in a small, fast‑paced team
• Comfort with an early‑stage startup environment with evolving priorities and high ownership

• Experience with financial markets, equity research, portfolio analytics, or trading systems
• Familiarity with charting libraries (D3.js, Recharts, Highcharts, Trading View) or data grid components (AG Grid, Tan Stack Table)
• Experience with design systems and component libraries
• Familiarity with Python and FastAPI or similar backend frameworks
• Experience with cloud platforms (AWS, GCP, Vercel) and modern frontend tooling
• Previous experience at an early‑stage startup or building data‑intensive products from scratch
• Understanding of accessibility standards (WCAG) and inclusive design

• Work on real‑world problems where your code ships to production and is used by actual users
• Get exposure to the full lifecycle of building a data product, including design, implementation, testing, deployment, and monitoring
• Collaborate closely with data science and research teammates and see how software engineering connects to quantitative analytics and decision‑making
• Learn directly from experienced founders and technical leaders in software, data, and product
• Join early enough to have meaningful ownership over projects, tools, and processes, and to influence the direction of the product and engineering stack
