Backend Engineer

EWJ Technologies builds scheduling and dispatch software for field service companies, from two-truck plumbing outfits to regional HVAC contractors. Our main product is a payroll and timekeeping app for hourly workforces, sold by subscription and supported from Guadalajara. Laptops are MacBook Pros, and you pick your own editor.

Role overview:

We are creating this position because the workload has grown. We want someone who writes boring, reliable code and leaves good logs behind. Remote position.

Main duties:

• Coordinate with frontend and mobile engineers on API contracts and versioning.
• Design and build REST and gRPC APIs in Go, Java or Python.
• Implement background jobs and event consumers using Kafka, SQS or RabbitMQ.
• Add caching with Redis where it actually helps, and remove it where it doesn't.
• Write integration and contract tests so API changes don't break consumers.

You'll need:

• 2-4 years of backend development experience in a production environment.
• Working knowledge of message queues or streaming platforms.
• Understanding of concurrency, transactions, idempotency and retries.

Nice to have:

• Elasticsearch or OpenSearch.

What you get:

• Private health insurance.
• Flexible hours.
• Training budget.
• 13th-month bonus.
• Home office equipment.
• Gym membership.
