As a Senior Frontend Engineer at Sensor Tower, you will not only build features, you will define how we build them. You will take ownership of major technical components, ensuring our applications are scalable, maintainable, and fast. In our lean and flat organization, your voice will shape the technical direction of our product, helping us deliver an intuitive, fluid user experience that helps our customers understand the digital ecosystem.

Architect and deliver complex, scalable frontend systems that are easy and effective, removing unnecessary complexity from our codebase. Lead technical decision‑making for medium‑to‑large scoped features, taking responsibility for the successful delivery of value to the customer, not just the completion of tickets. Mentor junior and mid‑level engineers through code reviews, pair programming, and by instilling quality‑first habits across the team.





Take ownership of the frontend stack by proactively identifying bottlenecks, technical debt, or systemic issues and driving the initiatives to fix them. Advocate for and drive best practices in React, TypeScript, and web performance optimization across the engineering organization. Collaborate deeply with Data Science and Backend Engineers to ensure seamless data flow and end‑to‑end system reliability, and use these partnerships to progressively expand your expertise across the full stack.

Software engineering experience with a deep specialization in modern JavaScript, TypeScript, and React. Design systems that handle complexity without becoming complicated, prioritizing long‑term maintainability. Competence in writing robust and efficient unit and integration tests using frameworks like Jest, Cypress, or Playwright.

Deep understanding of web performance, browser internals, and optimization techniques for data‑heavy applications. You are comfortable pushing back on requirements and proposing alternative solutions that drive better business outcomes and user experiences.

Experience in data visualization and analytics (handling large datasets, heavy DOM manipulation). A portfolio, GitHub history, or technical writing that demonstrates clean code, an eye for design, and the ability to solve complex architectural challenges. Familiarity with Ruby on Rails framework and NoSQL/Columnar databases (MongoDB, Clickhouse). #
