📋 Description

• Design and build greenfield REST or GraphQL APIs in Go that are secure, performant, versioned, and well-documented. • Establish and own the API as the integration layer and transitional architecture for Sharetec's Core modernization initiative. • Design and build complex scalable workloads supporting modern API standards and deployments (Docker, OAuth2/2.1, JWT, OpenAPI/Swagger, Terraform, etc.). • Define API design standards, contracts, and shared libraries that other teams can reuse. • Evaluate and recommend tooling and frameworks that improve developer productivity and integration reliability. • Design the data-normalization layer that maps between new services and the existing data schema. • Build the central integration hub that ties several distinct systems together through a common normalization model. • Partner with core processing engineers to ensure integration contracts remain aligned with the platform of record as it evolves. • Ensure data integrity, observability, and graceful failure handling across all integration endpoints. • Mentor and coach mid-level and junior engineers on API and integration design. • Lead design discussions and code reviews; promote a culture of clear communication and shared ownership. • Translate business and product needs into technical solutions alongside product managers and QA. • Contribute to documentation, internal tooling, and process improvements that make the whole team faster and better.

🎯 Requirements

• 6+ years of professional software development experience, including senior or technical-leadership responsibility on complex projects. • Deep, hands-on proficiency in Go for building backend and API services. • Extensive experience designing REST or GraphQL APIs from the ground up (not solely consuming third-party APIs). • Hands-on experience designing and building complex containerized workloads. • Familiarity with Infrastructure as Code solutions; Terraform or similar. • Strong database design and data-architecture skills, including data normalization and transitional/strangler-pattern architectures (PostgreSQL, SQL Server, or similar). • Solid understanding of API security, versioning, performance optimization, and observability. • Bachelor's degree in Computer Science, Software Engineering, or equivalent practical experience.
