Curitiba, Brasil Developros Tempo inteiro

(for a U.S.-based eCommerce technology company modernizing its fulfillment and logistics platforms)

About the Role

We’re seeking a Staff .NET Core Developer (C#) to design, build, and scale the internal systems that power one of the nation’s fastest-growing eCommerce logistics operations. You’ll work on complex, high-impact applications that connect digital tools with real-world fulfillment center technology — optimizing how inventory, orders, and operations flow across the network.

This is a hands-on technical leadership role — ideal for an engineer who combines strong architectural instincts with a builder’s mindset. You’ll shape foundational systems, mentor other developers, and collaborate across product, UX, and data teams to deliver stable, scalable, and future-ready software.

Responsibilities

- Design and develop backend systems and APIs using .NET Core (C#).
- Lead architectural discussions around scalability, performance, and maintainability.
- Partner with product managers, UX, and data engineers to translate operational requirements into technical solutions.
- Contribute to system modernization and codebase evolution, introducing best practices and automation.
- Support AI-assisted development initiatives to accelerate delivery and quality.
- Mentor mid-level developers and help elevate engineering standards across the team.
- Ensure reliability and observability through thoughtful design, testing, and monitoring.

Requirements

- 8+ years of professional experience developing enterprise applications in C# / .NET Core.
- Proven experience designing APIs, microservices, and distributed systems.
- Strong understanding of Azure or other cloud environments.
- Solid grasp of data modeling, performance optimization, and system integration.
- Comfortable navigating complex codebases and improving existing architecture.
- Excellent communication skills and the ability to collaborate with cross-functional teams.
- Self-starter mindset — curious, proactive, and driven to improve systems and team velocity.

Preferred Qualifications

- Experience in logistics, fulfillment, or eCommerce platforms.
- Experience designing distributed or asynchronous backend systems.
- Familiarity with CI/CD pipelines and DevOps practices in Azure.

What You’ll Love

- Working on mission-critical systems that power real-world logistics at scale.
- A culture that values craftsmanship, ownership, and initiative.
- Collaborating with time-zone-aligned teams in a highly technical, fast-moving environment.
- The chance to make architectural decisions that impact thousands of daily operations.
