Company Overview:

Our client is a U.S.-based SaaS company operating a production platform used daily by field teams to capture and sync inspection data. The product is established, actively scaling, and continues to evolve while supporting customers who depend on it in real-world conditions.

Your Role:

You’ll own backend systems that handle data, background processing, and integrations inside a live SaaS platform. New features still need to be built, but they must land safely inside workflows customers already rely on - often under unreliable connectivity and operational constraints.

You’ll take work from idea to production: clarifying requirements, designing backend systems, building them, and deploying safely. Some systems are new. Others exist but can’t support what the product needs next. Your job is to grow the platform without making it fragile.

This is a backend-first role. You’ll occasionally touch frontend or mobile code to support end-to-end workflows, but your core responsibility is backend reliability and system evolution.

You Bring:

• 5+ years owning production SaaS backend systems

• Strong experience building backend services in Python

• Hands-on experience with Celery + RabbitMQ in real systems

• Solid relational data modeling using SQLAlchemy

• Experience deploying and operating services on AWS (ECS required)

• Comfortable owning production issues end-to-end

Nice-to-Have

• Experience with React / Next.js or React Native

• Use of feature flags and staged rollouts

• Experience with third-party REST integrations

• Familiarity with production monitoring tools (e.g., Bugsnag)

• You’ve owned API integrations from design through deployment and monitoring

• Comfortable supporting AI-powered workflows

What’s Offered:

• Monthly compensation in USD, contractor model. Rate based on experience, scope of ownership, and location (U.S., Canada, or Latin America).

• Flexible paid time off, plus your local holidays.

• Fully remote, async-first culture with meaningful overlap across the Americas.

• Senior, hands-on peers who share responsibility for architecture and product decisions.

• Long-term opportunity at a profitable, stable company focused on product quality and steady growth.
