Role Summary:
As a Mid / Senior Frontend Engineer at Sensor Tower, you will make sure we're building the best possible products and features to support our users. In our lean and flat organization, you will also have a meaningful say in what and how we build out all aspects of our product.
Fulfill your potential with us
- Deliver complex, scalable frontend systems that are simple and effective, removing unnecessary complexity from our codebase.
- You will partner with Product Managers to co-author requirements and shape the scope, ensuring engineering feasibility is considered during ideation, not just execution.
- 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.
- Proactively identify bottlenecks, technical debt, or systemic issues and driving initiatives to fix them.
- Advocate for and drive best practices in React, TypeScript, and web performance optimization across the engineering organization.
- Collaborate 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.
What we are interested in
- Strong software engineering experience with a deep specialization in modern JavaScript, TypeScript, and React.
- Proven ability to architect complex state management. While our stack relies on TanStack Query and Zustand, we value engineers who understand the principles and can adapt expertise from other libraries like Redux or MobX.
- You can 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.
- "Product Owner" mindset. You care deeply about the "why" behind every feature, viewing code as a tool to solve real user problems. 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).
Additional Requirements
- Fluency in Russian and strong professional proficiency in English is required.
