About The Position

Throne is a fast-growing Series B startup focused on transforming public infrastructure by providing clean, safe, and smart restrooms in cities, transit agencies, and public spaces. With existing clients like LA Metro and Washington DC, Throne is expanding rapidly. The company aims to address the lack of quality public restroom facilities, providing peace of mind to people on the go. The Senior Full-Stack Engineer will own features end-to-end across the API (Node.js), web dashboard (React/Next.js), and mobile app (React Native). This is a high-autonomy role on a small team where the engineer will make architecture decisions, write specifications, and collaborate with product management. The ideal candidate thrives in a fast-paced startup environment and is comfortable with uncertainty. The role is eligible for remote work within the United States with minimal domestic travel expected. The base salary range is $150,000 - $200,000, with compensation dependent on experience, skills, and location. The position is also eligible for a comprehensive benefits package, including equity.

Excellent engineering judgment and a solution-driven way of thinking.
Strong proficiency with JavaScript / TypeScript.
Strong proficiency with Node.js and Express.

Responsibilities

Translate ambiguous product requirements into clear technical scope - data models, API contracts, and implementation options with their trade-offs.
Drive architecture decisions for new and existing services to support our constantly increasing scale, and back them with evidence (measured performance, capacity, failure modes).
Lead feature and story refinement; research and analyze the impact of new capabilities before they are built.
Partner proactively with product to clarify priorities, resolve ambiguity, and turn them into deliverable tasks.
Raise the engineering bar through code review and shared standards.
Use AI-assisted development tooling (Claude Code) with good judgment to increase your leverage in scoping, code review, implementation, and ramping quickly on unfamiliar systems.
