About The Position

Stefanini Group is hiring! Stefanini is looking for a Golang Developer, Dearborn, MI (Onsite) For quick apply, please reach out to Adil Khan at 248-728- 6424/ [email protected] We are looking for someone who will design and develop command-line tools, developer productivity utilities, and automation pipelines that simplify the testing resource reservation process. This is a hands-on senior engineering role focused on Golang, CLI tooling, and DevOps pipelines. Candidates must bring strong technical depth and practical experience building developer infrastructure and automation tools, not just application features. You will Design and implement functionalities for Golang-based command-line tools. Develop and implement unit, integration, and end-to-end tests. Write technical specifications for new features and improvements. Actively participate in Agile ceremonies and contribute to a culture of continuous improvement. Contribute to process improvements, CI/CD pipelines, and toolchain upgrades. Responsibilities Leading the end-to-end development process with a focus on clean code and maintainability. Expect the candidate to drive the development lifecycle, ensuring that the codebase is modular and adheres to SOLID principles. They should be able to perform deep code reviews that focus not just on logic, but on the long-term maintainability and extensibility of the feature. Application Support Expectation: Ownership of the production environment and a proactive approach to reliability. Should be proficient in 'Observability.' This means setting up structured logging, distributed tracing (Cloud Trace), and meaningful SLIs/SLOs. They should be able to lead a Root Cause Analysis (RCA) after an incident and implement preventative measures to ensure the issue does not recur. Application Testing Expectation: Implementation of a comprehensive, automated testing strategy. expect the candidate to be far beyond simple unit tests. They should be capable of designing/implementing a 'Testing Pyramid' that includes unit tests, integration tests using test containers, and end-to-end (E2E) contract testing to ensure that changes in one service do not break dependent systems. Docker Expectation: Mastery of containerization best practices for security and efficiency. Ability to create optimized, multi-stage Docker builds to keep image sizes small and reduce the attack surface. They must demonstrate knowledge of container security, such as running processes as non-root users and scanning images for vulnerabilities before they reach the registry. Google Cloud Platform Expectation: A broad understanding of the GCP ecosystem and Infrastructure as Code (IaC). Able to navigate the GCP Console and CLI fluently. More importantly, they should be able to provision infrastructure using Terraform, manage IAM roles with the principle of least privilege, and choose the right tool for the job (e.g., Pub/Sub for async messaging vs. Cloud Tasks for scheduled execution). SonarQube Expectation: Using static analysis to enforce high engineering standards across the team. expect the engineer to know how to integrate SonarQube (or experience with equivalent static analysis tooling) into a CI/CD pipeline to automate code quality checks. They should understand how 'Quality Gates' are defined and enforced that block pull requests if they introduce security vulnerabilities, technical debt, or if code coverage falls below a certain threshold (e.g., 80%). Strong proficiency in SQL, including advanced query writing, stored procedure development, and robust relational database design principles. Experience with data modeling and optimization for performance and scalability is highly valued. Details: Skills Required GCP Cloud Run, Go, API, Application Design, Application Development, Application Support, Application Testing, Docker, Google Cloud Platform, SonarQube GCP Cloud Run Expectation: The candidate should not just deploy a container, but understand the nuances of a serverless execution environment. Engineer to configure Cloud Run for production-grade workloads, including setting up custom VPC connectors for private database access, managing secrets via Secret Manager, implementing traffic splitting for canary releases, and optimizing 'cold start' times through min-instances and optimized container entry points. Go Expectation: Proficiency in writing idiomatic, high-performance, and concurrent code. Beyond basic syntax, the candidate must demonstrate expertise in Go routines and channels for concurrency, implement robust error handling patterns, and write performant code that avoids memory leaks. API Expectation: Deep understanding of API contract design, security, and lifecycle management. Should design RESTful or gRPC APIs using OpenAPI/Swagger specifications. I expect them to implement advanced patterns like idempotency keys for POST requests, versioning strategies (header vs. URL), and security protocols such as OAuth2/OIDC and rate limiting to protect the backend. Application Design Expectation: Ability to translate complex business requirements into scalable, maintainable architectures. Should be able to lead the design of a microservices architecture using Domain-Driven Design (DDD) principles. They should provide architectural diagrams that account for data consistency, circuit breakers for resiliency, and scalability requirements.
