Job Description ***POSITION IS HYBRID / 4 days per week in office at (*** Road office) iTek Center, 15575 Lundy Pkwy, Dearborn, MI 48126*** Position Description Join our team, where you’ll design and develop command-line tools, developer productivity utilities, and automation pipelines that simplify Developer experience. The goal of this role is to enable developers to spend less time maintaining testing hardware pipelines and more time innovating. 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. CONTINUATION OF PRIMARY SKILLS REQUIRED: Application Development Expectation: Leading the end-to-end development process with a focus on clean code and maintainability. • Example: I 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. • Example: 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. • Example: I 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. • Example: 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). • Example: 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. • Example: I 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%). Skills Required: ***See Expectations Outlined in Position Description field.*****SonarQube, GCP Cloud Run, Go, Application Development, Google Cloud Platform, Application Support, Application Design, API, Application Testing, Docker Skills Preferred: N/A Experience Required: Experience Required • Senior Software Engineer with 8+ years total engineering experience • 8+ years production Golang development, focused on CLI/DevOps/API work • Strong hands-on engineering background (not people-management or architect-only) • Proven track record building developer tooling and automation pipelines Experience Preferred: 0 Education Required: Bachelor's Degree Additional Information: • WORK STATUS: Hybrid (4 days per week in the office) Database Expertise: Strong proficiency in SQL, including advanced query writing, stored procedure development, and relational database design principles. Experience with data modeling and optimization for performance and scalability is valued. Full-Stack Development: Demonstrated full-stack development experience, with a solid understanding of integration and communication between front-end and back-end systems. Ability to contribute across the entire application stack. API Integration & Microservices: Proven experience integrating services and systems through APIs (e.g., RESTful, gRPC) or direct communication over a bus, focusing on efficient, scalable, and secure integration patterns. Familiarity with microservices architectures and event-driven systems is a plus. Software Quality & Testing: A strong commitment to software quality, including expertise in testing methodologies (e.g., unit, integration, end-to-end). Possesses a 'test-to-break' mindset, with the ability to identify vulnerabilities and design resilient, fault-tolerant software. Architectural Vision & Communication: Solid understanding of software architecture principles, design patterns, and best practices. Ability to design and clearly articulate complex technical concepts and decisions to technical and non-technical stakeholders. Systems Thinking & Integration: You recognize that your work is part of a larger system. You possess the willingness to learn other areas of the codebase and infrastructure to ensure your contributions fit seamlessly into the architecture. Continuous Learning & Problem Solving: A proactive mindset with ability and willingness to independently research, learn, and find solutions to unfamiliar challenges.
