Backend Engineer – Low-Latency Systems

This is a fully remote position, open to applicants in Latin America.

📋 Description

• Create backend services tailored to meet high demands for latency and throughput.

• Develop efficient concurrent systems with a focus on threading, asynchronous execution, synchronization, and memory management.

• Detect and resolve performance bottlenecks using code profiling, benchmarking, load testing, and runtime analysis.

• Design and enhance initialization, warm-up, and cold-start processes to reduce processing delays.

• Implement robust APIs, validation workflows, and rules-based processing that exhibit predictable and testable behavior.

• Maintain accuracy, effective error handling, observability, security, and operational reliability.

• Create services that enable real-time claim validation, decision engines, data processing, and enterprise integrations.

⛳️ Requirements

• Extensive backend engineering experience in a production environment, ideally using Golang.

• Proven skills in concurrent and parallel programming, addressing race conditions, synchronization, and resource contention.

• Comprehensive knowledge of memory management, application runtime behavior, and performance profiling techniques.

• Demonstrated capability to enhance latency and throughput in live production systems.

• Strong foundation in statistics, including understanding distributions, percentiles, variability, and performance metrics.

• Familiarity with APIs, databases, asynchronous processing, and distributed system architectures.

• Proficiency in using Docker, Git, automated testing, and CI/CD practices.

• Excellent debugging, problem-solving, and communication abilities.

• Experience in competitive programming is preferred.

• Background in developing payment, transaction-processing, financial, or healthcare systems is preferred.

• Experience in optimizing serverless execution and cold-start performance is preferred.

• Familiarity with deterministic rules engines, real-time decision systems, or high-volume event processing is preferred.

🏝️ Benefits

• An opportunity to tackle challenging performance issues and develop the foundational transaction-processing capabilities of a new production platform.
