About Nukleus

Nukleus is the career operating system for professional athletes — a single platform where contracts, financial data, NIL deals, social performance, and the entire ecosystem of advisors surrounding an athlete live together. We are building infrastructure that has never existed in professional sports, at a moment when the industry is ready for it. Our platform is live, our NFLPA and NBPA NDAs are signed, and we are growing fast. This role exists to make sure every athlete, agent, and advisor who touches the product has an experience that is fast, polished, and consistent — on every device.

The role

We are looking for a junior frontend engineer who cares deeply about how things look and feel, and who brings a methodical eye to finding and fixing what is broken. You will own the visual quality and responsiveness of the Nukleus platform — working across our React codebase to ensure our UI holds up on every screen size, every component matches our design standards, and users never get stuck on something that should just work.

This is not a passive role. You will be the first line of defense on bugs reported by real users — athletes, agents, and advisors — and your ability to triage clearly and communicate well will shape how quickly the team can respond. You will work closely with our senior engineers and, over time, grow into broader ownership of frontend features.

What you will work on

Responsive UI & cross-device quality

Own responsive behavior across the Nukleus platform — identifying and fixing layout issues on mobile, tablet, and desktop breakpoints in our React and Tailwind stack
Ensure the platform renders correctly across modern browsers and devices commonly used by athletes and advisors on the go
Conduct regular visual QA passes against new feature releases and flag regressions before they reach users

UI/UX compliance & design fidelity

Translate Figma designs into pixel-accurate, accessible components using React and Tailwind CSS
Audit existing screens for design consistency — spacing, typography, color, and component behavior — and bring them up to standard
Maintain and extend reusable component patterns across the codebase so new features stay visually consistent with what already exists
Work closely with Supabase-backed data displays to ensure UI states (loading, empty, error) are handled gracefully across all views

Bug triage & first-level resolution

Serve as the first point of contact for frontend bug reports — reproducing issues, categorizing severity, and either resolving them or routing them to the right engineer with full context
Maintain a running triage log and keep stakeholders informed on status without needing to be asked
Write clear, reproducible bug reports with steps, environment details, and screenshots that make downstream investigation fast

Technical customer support

Respond to support inquiries from athletes, agents, and advisors — diagnosing UI and platform issues, escalating when needed, and following up to confirm resolution
Translate technical findings into plain language for non-technical users and internal stakeholders
Document common issues and resolutions in an internal knowledge base to reduce repeat escalations over time

What we are looking for

Hands-on experience with React and a genuine understanding of component structure, props, and state — you have built or maintained real interfaces, not just completed tutorials
Solid grasp of CSS fundamentals — flexbox, grid, responsive breakpoints, and specificity — and comfort working with a utility-first system like Tailwind
A sharp eye for visual detail — you notice when something is 4px off, and it bothers you
Comfort working with browser DevTools to diagnose layout issues, inspect network requests, and narrow down the source of a bug
Clear written communication — you can explain a technical problem to a non-technical user without condescension and to a senior engineer without hand-holding
Self-directed and organized — you track what you are working on, follow up without being asked, and surface blockers early

Bonus points

Familiarity with Supabase or similar BaaS platforms — understanding how frontend components connect to backend data shapes how you triage and debug
Experience reading and writing TypeScript — our codebase is typed and you will be more effective if you are comfortable with it
Exposure to design tools like Figma — being able to pull measurements, inspect tokens, and compare specs directly saves handoff friction
Any background in sports, finance, or platforms built for professionals — understanding the users makes you a better advocate for them
Experience supporting end users in a SaaS context — knowing what good support looks and feels like from the user's side

Why this role is different

Most junior frontend roles put you on a feature queue and ask you to ship components. This one asks you to be accountable for the full quality of the visual experience — across every screen, every user type, and every edge case the product surfaces. You will interact directly with real users (professional athletes and their representatives), which means your work has immediate, visible impact. The platform is live, the user base is growing, and the standard we hold ourselves to is high. If you are the kind of engineer who takes pride in craft and wants to own something real from day one, this is the right fit.

Why Nukleus

We are an early-stage company with real traction, blue-chip athlete partners, and a product that addresses a genuine gap in a multi-billion dollar industry. You will have direct access to leadership, mentorship from senior engineers, and the satisfaction of seeing your work used by professional athletes and the teams that represent them. Competitive salary and benefits.

Pay: From $40.00 per hour

Work Location: In person
