Valkyrie
Full-time Employment
: Ability to work as a full-time employee
Location:
Austin, TX (Hybrid)
About Us Valkyrie is an applied science firm that builds industry-defining custom AI, ML and Knowledge Engineering solutions. Our interdisciplinary applied science teams support our clients from data normalization all the way through model deployment. Our work can be found across industry from SiriusXM, Activision, Chubb Insurance, and the Department of Defense, to name a few.
Valkyrie is developing an internal product, leveraging best-in-class AI technology. This position will help spearhead the product development. This is an early stage launch and will require someone who is ambitious, takes initiative and thrives in building foundational frontend engineering practices. Experience at an early‑stage company is a plus.
We're looking for a Senior Frontend Engineer who can transform thoughtful Figma designs into pixel‑perfect React components for our multi‑tenant knowledge graph platform. This role requires a rare combination of exceptional implementation skills, data visualization expertise, and deep understanding of frontend security for regulated environments. The senior frontend engineer will build and maintain a component library using Mantine UI with consistent dark mode support and accessibility standards (WCAG 2.1 AA). This role will also implement 2D knowledge graph visualizations using D3, create smooth animations and micro‑interactions, and collaborate with backend engineers to integrate REST/GraphQL APIs. You'll own frontend performance optimization, write comprehensive component tests, and implement frontend security best practices including CSP policies, XSS prevention, and secure authentication flows.
Senior Frontend Engineer Qualifications We encourage candidates to apply even if they don’t have 100% of the below qualifications. We believe in a holistic approach when evaluating talent for our team and post new roles often, so even if this role isn’t quite right, we want to meet you!
Bachelor’s degree in STEM, Design or related field
5+ years of production experience building React applications with strong design implementation
5+ years of expert‑level CSS skills including Flexbox, Grid, CSS‑in‑JS, animations, and responsive design
3+ years of experience translating Figma designs to production code with high fidelity

3+ years of experience with component libraries (Mantine UI, Material‑UI, or similar)
3+ years of experience with data visualization libraries (D3.js, Three.js, or similar)
5+ years track record building performant UIs with code splitting, lazy loading, and memoization
3+ years of understanding accessibility standards (WCAG 2.1 AA) and assistive technologies
3+ years of experience with frontend testing using Jest, React Testing Library, and Playwright
Strong eye for design details including spacing, typography, color, and interaction states
Design system experience including design tokens and component documentation (Storybook)
Comfort working in an environment where design quality matters
Experience with Agile team methodologies including daily stand‑ups
Strong experience in effective collaboration and technical communication within multidisciplinary teams, particularly with designers and backend engineers
Ability to provide constructive implementation feedback during design reviews and suggest design improvements based on technical constraints

Experience building multi‑tenant SaaS applications with tenant‑specific theming
Backend development experience with Node.js and Express
Experience with form libraries (React Hook Form, Formik) and validation (Zod)
Experience with real‑time features using WebSockets or Server‑Sent Events
Understanding of HIPAA, SOC 2, or similar compliance requirements in UI implementation
Experience with state management libraries (Zustand, Redux, Recoil)
Experience with TanStack Query (React Query) for API data management
Experience with responsive layouts that provide seamless user experience across desktop and mobile devices
