We’re looking for our next Intermediate Software Engineer. Could It Be You?

As an Intermediate Software Engineer, you will take focused ownership of specific systems or sub-systems within our squad’s portfolio. You aren't just writing code; you are proposing engineering solutions, optimizing existing systems, and ensuring quality through rigorous testing and peer reviews. You are expected to operate independently on complex tasks while collaborating with senior mentors on high-complexity architectural challenges.

Need more details? Keep reading…

System Ownership: Drive the development and maintenance of specific sub-systems, ensuring they align with the broader squad portfolio.
Execution & Quality: Independently own tasks from end-to-end. You will define and execute comprehensive test plans—including unit, integration, and performance testing—to ensure a robust production environment.
Engineering Excellence: Propose technical solutions within your domain and actively participate in code reviews to maintain high standards of quality and maintainability.
AI-Accelerated Development: Proactively leverage AI coding assistants and LLMs (e.g., Cursor, Claude, Gemini) to accelerate routine tasks, scaffold boilerplate code, assist in debugging, and enhance overall engineering productivity without compromising code quality or security.
Troubleshooting: Identify, troubleshoot, and optimize bottlenecks or bugs within your systems to improve overall performance.
Active Engagement: You don't just sit in meetings; you ask clarifying questions, reflect back requirements to ensure understanding, and contribute to solution intent documentation.
Documentation: Ability to write clear code-level documentation and technical specifications for your peers and stakeholders.
Cross-Functional Teamwork: Effectively collaborate with cross-functional teams, sharing knowledge and aligning your individual work with the overall team strategy.

So are YOU our next Intermediate Software Engineer? You are if you have…

Engineering Principles: Solid experience applying core engineering principles (SOLID) and a strong understanding of modern architectural patterns, specifically
Clean Architecture, Microservices, and CQRS (e.g., using MediatR).
Tooling Mastery: Hands-on experience with our core stack—particularly .NET 8 / C#—and proficiency with both SQL and NoSQL databases (specifically CloudSQL, MongoDB, and Firestore).
AI Tooling & Mindset: Experience (or strong willingness to learn) integrating AI tools into your daily workflow. You know how to effectively prompt AI to solve problems, generate tests, or explain complex code, while still applying critical engineering judgment to review and validate the AI's output.
Decision Making: Proven ability to make complex engineering decisions on non-critical systems, design resilient solutions, and follow functional requirements with minimal supervision.
Quality Focused: A track record of delivering high-quality work, with strong habits in writing comprehensive Unit and Integration tests, as well as familiarity with modern QA methodologies (experience with Cypress for E2E testing is a huge plus).
Micro-Leadership: Ability to lead low-to-medium complexity tasks, providing technical guidance and PR reviews to more junior team members.
Ownership Mentality: You hold yourself accountable for your delivery—from local development to production deployment—actively seeking feedback to continuously improve your performance and technical craft.
Event-Driven Systems: Practical experience designing and working with event-driven architectures and asynchronous message brokers (specifically Google Cloud Pub/Sub).
Security & Authentication: Familiarity with modern API security practices, implementing JWT bearer authentication (e.g., Azure AD / Identity SDK), and Role-Based Access Control (RBAC).
