Job description

Staff Frontend Software Engineer - Platform

Lehi, Utah

We are obsessed with the hero's journey at JobNimbus. Every person has a hero's journey—Hermione Granger, James T. Kirk, Frodo Baggins, Anna & Elsa, Nacho Libre, and even YOU! This is our “call to adventure” to come check out JobNimbus. What do you have to lose? You might make a few new friends, learn about a sick new company doing some amazing things, and maybe even land a new job!

Mission:

Lead the architecture, foundation, and infrastructure of JobNimbus’s frontend platforms. You will serve as the technical anchor driving our monorepo migration and building the shared agent surfaces that power all AI features across the company. Partnering with cross-functional engineering teams, you will eliminate technical debt, elevate UI infrastructure, and lay the foundation that accelerates every product feature we deliver.

What You'll Be Doing:

Own the frontend technical strategy on the Platform team, focusing strictly on core foundational work, infrastructure, and architectural excellence rather than feature-factory output.

Drive the completion of our monorepo migration, transitioning remaining legacy surfaces (16 of 46) to modern, scalable frontend standards.

Architect and build the shared agent surfaces, approval screens, and underlying framework that every team’s AI capabilities will run through.

Evolve and maintain module and design-system infrastructure, ensuring consistency, high performance, and effortless reusability for all product engineers.

Act as the frontend expert on the platform team, guiding decisions around system performance, UI architecture, build tooling, and state management.

Write production-grade, highly resilient frontend code on the most complex and critical shared components of the platform.

Break down architectural friction across teams, unblocking product units by creating clean module boundaries and shared primitives.

Raise the bar on frontend quality, accessibility, testing standards, and web performance metrics across the entire engineering organization.

Mentor engineers across teams in modern web architecture, component design, and sustainable software practices.

• Leverage AI-assisted tools to improve development velocity, streamline repetitive infrastructure work, and enhance overall code quality.

What Makes You the Hero for This Job:

8+ years of software engineering experience with a heavy focus on complex, large-scale web applications and frontend architecture.

Proven track record of designing, building, and maintaining frontend platform infrastructure, shared component/design libraries, and monorepo architectures (e.g., Nx, Turborepo).

Direct experience building shared UI surfaces, developer tools, or AI/agent interaction patterns (approval screens, workflow orchestrators, or interactive cards).

Strong architectural perspective on micro-frontends, module federation, and legacy system migrations.

Proven ability to lead technical strategy within a domain and influence cross-functional teams without direct authority.

Comfort working in infrastructural roles where your “customers” are both end-users and your fellow software engineers.

Track record of mentoring engineers, establishing UI standards, and raising the engineering bar across an organization.

Strong knowledge of web performance metrics, front-end security practices, automated testing (unit, integration, e2e), and CI/CD pipelines for web applications.

Experience managing and designing shared state, complex client workflows, and resilient component APIs.

Superpowers:

• Extreme Ownership. You own the outcomes, drive initiatives, and solve problems proactively. If you need direction and someone to hold your hand, this job is not for you.
• Customer Obsessed. Everything we build should leave our customers saying, “Aw dip. This product is off the charts cool. Whoever wrote that code deserves a raise!”
• Proactive Learning. You stay ahead of the curve, continuously learning and implementing cutting‑edge technologies.
• Team Commitment. You build, mentor, and lead a high‑performance engineering team that delivers results together.
• Self Awareness. You know your strengths, weaknesses, and how to surround yourself with the right talent to succeed.
