Dugu is a Chilean software engineering company that works with international teams to design, build, and maintain production software and technology platforms. We bring experienced engineers into complex environments where reliability, technical judgment, collaboration, and long-term maintainability matter.

This role is intended for an experienced engineer with deep backend expertise who is comfortable working across legacy systems, modern services, databases, messaging infrastructure, cloud environments, and production operations.

You will be expected to take ownership of complex technical problems, make architectural and implementation decisions, identify risks before they become incidents, and help other engineers navigate difficult technical challenges.

Backend Architecture & Technical Leadership

• Design and evolve backend services, APIs, data models, integrations, and distributed systems.
• Lead technical design for complex initiatives and evaluate architectural alternatives.
• Communicate trade-offs around scalability, reliability, performance, security, and maintainability.
• Identify opportunities to simplify systems, reduce technical debt, and modernize existing architecture.

Software Development & Delivery

• Design, implement, test, review, and deploy production-quality backend software.
• Own complex features and services from technical analysis through deployment and production operation.
• Make pragmatic decisions when working with legacy systems.
• Balance delivery speed, maintainability, and technical risk.

Distributed Systems & Reliability

• Work with relational databases, caching, queues, asynchronous processing, APIs, and service integrations.
• Apply sound judgment around transactions, concurrency, retries, idempotency, failure handling, and data consistency.
• Identify bottlenecks and improve application, database, and system performance.

Operational & Infrastructure Ownership

• Take ownership of the operational health of production systems.
• Improve monitoring, logging, metrics, alerting, CI/CD, and observability.
• Participate in incident response, root cause analysis, and remediation.
• Work comfortably with AWS, hybrid infrastructure, Linux, and on-premise environments.

Technical Leadership & Collaboration

• Provide technical guidance through architecture discussions, code reviews, debugging, documentation, and mentoring.
• Partner with Engineering, Product, Operations, and QA to translate requirements into reliable technical solutions.
• Communicate technical decisions, risks, dependencies, and trade-offs clearly across distributed teams.

• Experience designing high-availability or mission-critical systems.
• Experience with real-time communications, telecommunications, VoIP, WebRTC, SIP, or related technologies.
• Experience operating systems with significant production traffic or strict availability requirements.
• Experience with containerized applications and Docker.
• Experience with infrastructure-as-code or cloud automation.
• Experience designing observability strategies using metrics, logs, tracing, and alerting.
• Experience decomposing or modernizing legacy monolithic systems.
• Experience mentoring engineers or acting as a technical lead on complex projects.
