Responsibilities

• Design, develop, and maintain scalable backend services and APIs using Golang, ensuring high performance and reliability.
• Lead migration efforts from a Python monolith to microservices: propose migration strategies, run pilot services, and coordinate cutovers.
• Architect and implement secure, RESTful APIs that serve as the backbone for our applications, facilitating seamless data exchange in JSON format.
• Manage and optimize PostgreSQL databases, ensuring data integrity, performance tuning, and efficient query design.
• Deploy and operate services on AWS and Kubernetes (EKS); work with Airbyte and related data integration tools as needed.
• Collaborate with product managers, frontend engineers, and other stakeholders to deliver high-quality features aligned with business goals.
• Drive improvements in development processes, tooling, and technologies to enhance team productivity and product quality.
• Work with messaging systems such as Apache Kafka to build event-driven architectures that support real-time data processing and integration.
• Apply sound software engineering principles to design maintainable, testable, and extensible codebases.
• Participate in code reviews, design discussions, and architectural decisions to uphold engineering standards and quality.

Requirements

Must-Have Skills

• Golang: Extensive experience in developing backend applications using Go, with a strong understanding of its concurrency model, idiomatic patterns, and performance optimization techniques.
