POSITION SUMMARY

We seek an experienced, collaborative, and resourceful Senior Web Engineer to join our team. Our Early Bets initiatives are critical to EarnIn's success, providing new experiences and products that empower users with a more comprehensive ecosystem of solutions. We seek engineers who thrive in uncertainty, excel at defining technical solutions in ambiguous environments, and collaborate closely with Product teams to refine requirements. The ideal candidate has experience building 0-to-1 products and demonstrates a strong ability to design and implement scalable architectures that support rapid product evolution. Candidates with backgrounds in early-stage software products engineered for scale, or those who have worked in Research & Development on new technologies, will fit well on our team.

The Mountain View base salary range for this full-time position is $228,000 - $279,200 plus equity and benefits. Our salary ranges are determined by role, level, and location. This is a remote role based in the United States, though a hybrid arrangement in Mountain View with in-office work is also possible

WHAT YOU'LL DO
  • Partner with Product and Design to define, build, and evolve user experiences using modern frontend technologies.
  • Own and evolve the frontend architecture to ensure scalability, performance, accessibility, and long-term maintainability.
  • Lead the design and implementation of complex frontend systems using React, TypeScript, and Next.js, including SSR, routing, data fetching, and performance optimization.
  • Establish and uphold frontend engineering standards, including patterns, tooling, testing strategies, and CI/CD best practices.
  • Drive cross-team technical initiatives, aligning frontend architecture with backend APIs, platform capabilities, and product strategy.
  • Proactively identify technical risks and opportunities, providing clear technical direction and trade-off analysis.
  • Mentor and guide frontend engineers, raising the bar on code quality, architectural thinking, and delivery practices.
  • Design and implement robust unit, integration, and UI automation tests to ensure reliability and confidence at scale.
  • Define and monitor frontend metrics (performance, reliability, user behavior) to inform product and technical decisions.

WHAT WE'RE LOOKING FOR
  • Bachelor's (or higher, e.g., MS, or PhD) in Computer Science or a related technical field involving coding or equivalent technical experience
  • Expert-level proficiency in modern frontend development, including HTML, CSS, JavaScript, TypeScript, React, and Next.js.
  • Strong experience with frontend architecture, including state management, component design, design systems, micro-frontends (or modular architectures), and performance optimization.
  • Experience building and operating production web applications using server-side and client-side rendering.
  • Deep understanding of software engineering best practices across the SDLC, including testing, code reviews, observability, and operational excellence.
  • 4+ years of industry experience, with significant depth in frontend or web platform development.
  • Experience working in cloud-based environments (AWS, GCP, or Azure), particularly as it relates to frontend delivery and integration.
  • Experience using AI-assisted development tools (e.g., Copilot, Cursor, LLMs) is a plus
