amo is hiring a Senior Full Stack Web Engineer to join as an early member of the Web team. You will build and own web platforms that transform large datasets into products people love to use, with maps and location data at the core. You'll work across the full stack—from data modeling to pixel-perfect UI—taking ownership of central systems and features as you grow with the team.
Your day-to-day responsibilities include:
**Platform Engineering**: Design and build robust, scalable web platforms end-to-end in TypeScript, including APIs, services, data access layers, and UI. You'll make architectural decisions and set patterns for the team.
**Workflows & Data Pipelines**: Architect durable, long-running workflows and background processes using workflow orchestration (Restate). Build pipelines that reliably move data between the warehouse, databases, and products at scale.
**Data Modeling & Visualization**: Model large datasets for fast querying and visualization. Choose the right aggregations, pre-computations, and storage across Postgres and BigQuery. Turn data into clear, interactive, beautiful visualizations with privacy built in from the start.
**Maps & Geospatial Data**: Bring geospatial data to life on the web. Render large amounts of location data on interactive maps, keeping them fast, polished, and insightful.
**Roadmap & Ideation**: Contribute actively to the roadmap, identifying tradeoffs and bringing both product and engineering perspectives.
**Ownership**: You own the architecture, performance, monitoring, and reliability of everything you ship. The team values engineers who take full ownership and proactively address issues.
The company emphasizes that AI is part of daily work—you should use AI tools to multiply your output, not to cover gaps in expertise. You'll drive complex changes, judge quality, spot subtle errors, and stand behind every line that ships.
