Senior Full-Stack Software Engineer

Job Description

About the Platform

Our next-generation smart-parking platform delivers friction-free access and integrated digital payments. Help support our engineering team in delivering multiple high-value flagship features in a fast-paced environment. You'll co-author specs, shape data and service layers, and ship production-ready code that scales across millions of parking sessions.

What You’ll Do

• Drive work independently—take a Jira ticket or one-page spec and turn it into reviewed PRs, tests, and a clean deployment plan.
• Shape specs & data models alongside senior teammates; draft migrations and update Sequelize models.
• Implement services & APIs in TypeScript/Node (Firebase Functions, Express) that integrate with Stripe, Twilio, and internal services.
• Write solid unit tests with Jest; pair with our SDET on integration coverage and CI gates.
• Harden webhooks & async flows (payments, LPR events) with idempotency, retries, and monitoring hooks.
• Review code and raise flags early—spot gaps, propose fixes, and keep the release train on time.
• Collaborate asynchronously in a fast-paced, remote setup—clear written updates, proactive risk calls, zero babysitting.
  
  

You Have

• 5+ years of professional software-engineering experience shipping customer-facing web applications using TypeScript/JavaScript (Node.js on the back end and a modern front-end framework).
• Demonstrated end-to-end ownership of features—from data-model design through production deployment—with minimal oversight.
• Extensive experience building Node.js services and RESTful APIs, backed by strong SQL skills
• Strong command of automated testing in Jest and a test-first mindset.
• Ability to commit to a full-time (40 hrs/week) schedule aligned with U.S. business hours and to communicate clearly in English, both written and spoken.
  
  

Nice to Have

• Hands-on Stripe (Payments or Connect) or similar payment platform experience.
