Senior Backend Engineer — Python or Node.js, AWS

Location: Remote — Argentina, Chile, Colombia, Brazil, Uruguay, Peru, Mexico Salary: 5000 - 5500 USD per month Job Type: Full-time contract Date Posted: September 11, 2026

Project Brief

We're building a HIPAA-compliant platform on AWS for a healthcare client, including a real-time eligibility check engine that integrates with a clearinghouse via EDI (270/271), an encrypted coverage data store, and alerting. You'll build directly against a design set by our Solutions Architect, on a small senior team moving fast over roughly 10 weeks. This is heads-down, high-ownership backend work on a real production system handling healthcare data.

Must-Haves

• Senior backend engineering experience (5+ years)
• Strong in Python or Node.js/TypeScript
• PostgreSQL and REST API design
• Solid working AWS experience: Fargate/ECS, SQS, Secrets Manager, CloudWatch
• Able to execute infrastructure-as-code designed by an architect
• Strong experience integrating third-party APIs and handling messy external data

Nice to Have

• Healthcare EDI (ANSI 270/271) or clearinghouse integration experience
• Event-driven / queue-based pipeline experience
• HIPAA / PHI handling experience
• Terraform or AWS CDK

What You Will Do

• Build the backend and integrations to the architect's design, including the HIPAA-AWS foundation (infrastructure-as-code)
• Implement the clearinghouse eligibility integration: build the EDI 270 request, call the REST API, parse the 271 response
• Build the check engine: scheduler/SQS-driven daily eligibility sweeps, pending-enrollment polling, and countdown logic
• Build and maintain the encrypted coverage data store and alerting
• Own integration-path testing end-to-end
• Work heads-down with daily standups, delivering to the contract that the front-end/automation engineer consumes

Why This Could Be Your Next Big Move

• Real ownership of critical systems — you'll own the integration layer and check engine end-to-end, not just a slice of it
• High-priority, fast-moving build — a small senior team shipping a production healthcare platform in weeks, not quarters
• Work with a strong technical architect — the design and infra decisions are set, so you can focus on building well against a clear plan
• Healthcare-grade, high-stakes engineering — meaningful experience with HIPAA-compliant systems and EDI integrations that's rare to get hands-on with

Benefits & Compensation

• 💵 5000 - 5500 USD per month — paid in USD, bi-weekly via Deel
• 🌎 Fully Remote — work from anywhere in Latin America
• 📄 Long-term contract — starting with a 6-month contract, then full-time
• 🏖 Paid PTO
• 🤝 Referral Program — earn a bonus for referring talent that gets hired
