Job Description

We are looking for a Senior Backend Engineer (Golang) to design and build scalable, reliable, and secure backend systems. The role involves developing distributed services, designing robust APIs, implementing event-driven architectures, and ensuring high standards of performance, maintainability, and system reliability.

While the primary focus is backend development, occasional contributions to React-based frontend functionality may be required.

Responsibilities

- Design, implement, and maintain scalable backend services in Golang, including RESTful APIs and stable data contracts that evolve safely over time.
- Implement and manage asynchronous, event-driven communication, with strong guarantees around message reliability, idempotency, error handling, and backward compatibility.
- Design and develop distributed systems and microservices with a focus on scalability, resilience, and maintainability.
- Optimize application performance, reliability,



and resource utilization in production environments.
- Participate in architecture discussions and contribute to technical decision-making.
- Conduct code reviews and support knowledge sharing across the engineering team.
- Design code with testability as a core principle, writing and maintaining unit and integration tests for APIs, business logic, and integrations.
- Design and maintain secure APIs and service integrations, applying best practices in authentication, authorization, and identity management.
- Build integrations with enterprise platforms such as Salesforce, Microsoft Dynamics, ServiceNow, Genesys Cloud, and other third-party systems.
- Design and maintain reliable integrations between internal services and external enterprise platforms.
