[Hiring] Senior Back End Engineer @Software Mind

Role Description

We are seeking a Senior Developer to design and build backend services for a client's e-commerce platform, built on a distributed microservices architecture with event driven communication between services. This role covers hands-on development across the service layer, from domain modeling through API design to production deployment, working within an established clean architecture pattern and collaborating closely with architects, QA, and other developers on the team.

Key Responsibilities

• Service development: Design and implement backend microservices following clean architecture principles (domain, application, infrastructure, and API layers), ensuring clear separation of concerns and testability.
• API design: Build and maintain REST and/or GraphQL APIs, defining data contracts and ensuring consistent request and response models across services.
• Event driven integration: Implement and consume event driven flows across message queues (e.g., AWS SQS/SNS style publish/subscribe), including webhook handling, retry logic, and error handling.
• Data modeling and persistence: Design data models and implement persistence logic against NoSQL and/or relational databases, applying appropriate patterns (repository, unit of work) for testability and maintainability.
• Authentication and authorization: Implement JWT based authentication and authorization flows, integrating with identity providers such as Keycloak or an equivalent service.
• Testing: Write unit, integration, and BDD style tests to ensure code quality and prevent regressions, and maintain test coverage as services evolve.
• CI/CD and deployment: Build and maintain CI/CD pipelines for build, test, and deployment to cloud infrastructure, including containerized services on managed platforms such as AWS ECS.
• Code review and mentorship: Participate in code reviews, uphold engineering standards, and mentor less experienced developers on the team.
• Cross service collaboration: Work with architects, QA, and other developers to resolve integration gaps, clarify requirements, and deliver features across multiple services within sprint timelines.

Qualifications

• 5+ years of professional software development experience building backend services in a modern object oriented or statically typed language, such as C#/.NET or Java.
• Demonstrated experience designing and building microservices, including REST and/or GraphQL APIs.
• Solid understanding of clean architecture or similarly layered design patterns, with clear separation between domain, application, and infrastructure concerns.
• Experience with NoSQL and/or relational databases, including schema and data modeling and query optimization.
• Practical experience with event driven architectures and message queues, such as AWS SQS/SNS or an equivalent service.
• Experience writing automated tests (unit, integration, and/or BDD) and integrating them into a CI/CD pipeline.
• Comfortable working in an agile team environment, prioritizing pragmatically under sprint deadlines.
• Strong written and verbal communication skills, comfortable flagging blockers, gaps, and risks early and directly.
• Experience with disciplined AI assisted software development practices, including specification driven development, TDD, and iterative refactoring. Able to mentor engineers on using AI coding tools effectively within structured development workflows.

Preferred Qualifications

• Backend experience with ASP.NET Core and related tooling (e.g., MediatR/CQRS, xUnit, Reqnroll/BDD, FluentValidation) or an equivalent stack in another language.
• AWS experience (ECS, SQS, SNS, or similar managed container/queue services).
• Experience with Docker and containerized deployments.
• Experience in e-commerce, order management, or similarly transactional domains.
• Familiarity with identity providers such as Keycloak or Azure AD for authentication and authorization.
• Experience integrating with third party platforms via webhooks, such as storefront platforms or payment providers.

• Flexible schedule and Work From Anywhere
