Software Engineer I, Fullstack (Trail Data)

📋 Description

• • Own the full-stack lifecycle of features that power the world’s largest and most trusted trail dataset. You will design, build, test, deploy, and maintain ReactJS front-end components and Ruby on Rails back-end services that enable our Trail Data team to ingest, curate, and publish millions of trail records with millisecond-level accuracy.
• • Partner daily with cartographers, data analysts, and product managers to translate complex geospatial requirements into elegant, scalable software. You will sit in on stand-ups, run design reviews, and demo prototypes that directly influence how quickly we surface new trails to 40 million explorers.
• • Architect resilient APIs and background jobs that process GPX uploads, satellite imagery, and user-generated corrections at petabyte scale. Expect to refactor for performance, add caching layers, and tune SQL queries so that a contributor in New Zealand sees their edit live within seconds.
• • Craft pixel-perfect, accessible React interfaces that allow non-technical stakeholders to visualize trail geometry, elevation profiles, and quality scores on an interactive map. You will leverage MapBox GL, TypeScript, and CSS-in-JS to deliver responsive layouts that work equally well on a 4K monitor and a phone at 10,000 ft.
• • Instrument everything—latency, error rates, user flows—using Datadog and NewRelic. You will set SLIs, build dashboards, and wake up on-call only when it really matters because you baked observability in from day one.
• • Champion continuous deployment. Your pull requests trigger GitHub Actions, spin up Docker containers, run automated tests, and deploy to AWS (EC2, S3, RDS, CloudFront) multiple times a day without drama.
• • Squash gnarly bugs across the stack: from a memory leak in a React hook to a race condition in a Sidekiq job. You will reproduce issues locally, write regression tests, and ship fixes before hikers notice.
• • Experiment fearlessly with AI tools to accelerate your workflow—whether that’s generating test cases, summarizing code reviews, or prototyping UI variations. You will share prompt patterns and GPT plug-ins with the team so everyone levels up.
• • Mentor and be mentored. You will pair program with senior engineers, conduct lunch-and-learns on Rails 7 features, and welcome interns who are pushing their first commits to production.
• • Embrace AllTrails’ mission of inclusive access to nature. You will build features that surface wheelchair-friendly paths, multi-language trail names, and safety alerts so every explorer feels welcome on the trail.
