Senior Full-Stack Engineer
# Senior Full-Stack Engineer **FlexiSchools** · Surry Hills NSW 2010 · `On-site` 🕒 **Статус:** *Опубликовано: сегодня* · *Источник: Indeed* --- ### About the Role Role Purpose The Senior Full-Stack Engineer designs, develops, tests, implements and supports scalable software applications and systems across the Flexischools platform. This role has a strong backend engineering focus, working primarily with C#, .NET, ASP.NET Core, AWS and distributed services, while also contributing to customer-facing applications using ReactJS and TypeScript. The engineer designs maintainable services and APIs, applies strong software architecture and Domain-Driven Design principles, and contributes across the full software development lifecycle from requirements analysis and design through to production support. As a senior engineer, the role also influences technical direction within the squad, contributes to engineering standards, and supports the growth of other engineers through collaboration, mentoring and code reviews. Accountabilities Deliver high-quality software aligned with product priorities, architectural direction and engineering standards. Research, analyse and evaluate system and program requirements to inform software design and effective technical solutions. Design, develop, modify, test, implement and maintain backend services, APIs, integrations and supporting web applications. Contribute to technical design and architecture, with a focus on maintainability, scalability, reliability and clear domain boundaries. Work closely with Product, Engineering and other stakeholders to translate business requirements into effective technical solutions. Apply appropriate automated testing, observability, security and quality practices throughout the development lifecycle. Own software through to production, including deployment, monitoring, troubleshooting and incident resolution. Write, update and maintain technical documentation, engineering standards and records of significant design decisions. Identify and mitigate risks affecting software performance, reliability and security. Mentor engineers, provide constructive technical feedback and contribute to a strong engineering culture. Role Specifics Design, develop and maintain backend services and APIs using C#, .NET and ASP.NET Core. Apply Domain-Driven Design, Onion Architecture, SOLID principles and other appropriate software design patterns to create maintainable systems with clear separation of responsibilities. Design domain models, application services, APIs, persistence layers and integration patterns that support evolving business requirements. Identify technology limitations and deficiencies in existing systems, and modify or modernise software to correct errors and meet changing requirements. Build and maintain distributed and microservice-based systems operating within AWS. Work with AWS services and infrastructure to deliver secure, scalable, observable and resilient applications. Contribute to CI/CD pipelines, infrastructure automation, deployment practices, monitoring and other DevOps responsibilities as part of normal software ownership. Manage testing and automation of software deployments to support reliable, repeatable releases. Develop and maintain frontend applications using ReactJS and TypeScript where required, enabling delivery of features across the full technology stack. Build well-structured frontend components and integrate applications effectively with backend APIs and services. Design and integrate REST APIs, asynchronous messaging, third-party integrations and other service-to-service communication patterns. Work with relational databases and persistence technologies, including Entity Framework and SQL. Implement automated unit, integration, contract and end-to-end testing appropriate to the solution. Test, debug, diagnose and correct errors and faults across development and production environments. Collect and analyse operational metrics to monitor performance, reliability and quality, and drive continuous improvement. Participate in architecture discussions and technical decision-making within the squad, documenting significant decisions where appropriate. Conduct code reviews and help maintain strong engineering standards across the codebase. Support production systems through monitoring, troubleshooting, root-cause analysis and implementation of sustainable fixes rather than short-term workarounds. Identify opportunities to simplify systems, reduce technical debt and improve developer experience and operational reliability. Skills & Experience Essential Tertiary qualification in Software Engineering, Computer Science or a related field, or equivalent commercial experience (typically 5+ years). Strong commercial experience with C# and modern .NET. Strong experience building APIs and backend applications using ASP.NET Core. Strong understanding of object-oriented design, SOLID principles, dependency injection and automated testing. Experience applying architectural patterns such as Onion Architecture, Clean Architecture or similar layered approaches. Practical experience with Domain-Driven Design concepts, including domain modelling, bounded contexts, aggregates, and separation of domain and infrastructure concerns. Strong experience designing and developing REST APIs and service integrations. Experience with Entity Framework Core and relational databases such as SQL Server or PostgreSQL. Strong understanding of distributed systems and microservice architectures. Experience building and operating applications in AWS. Experience with DevOps practices including CI/CD, automated deployments, infrastructure configuration, monitoring and production support. Commercial experience with ReactJS and TypeScript, with the ability to contribute effectively to modern frontend applications. Strong understanding of software engineering quality practices, including automated testing, code reviews, observability and secure development. Experience taking ownership of software through design, implementation, deployment and production operation. Strong communication and collaboration skills, with the ability to work effectively across engineering, product and other business functions. Highly Desirable Experience with AWS services such as ECS, API Gateway, SQS, SNS, EventBridge, RDS, CloudWatch or similar. Experience with Docker and containerised application deployment. Experience with event-driven architecture and asynchronous messaging. Experience designing systems around complex business domains and transactional workflows. Experience with infrastructure-as-code technologies such as AWS CDK, Terraform or CloudFormation. Experience with authentication, authorisation, identity and role-based access control. Experience working with payment systems or other high-volume transactional platforms. Experience improving legacy systems or progressively modernising existing applications. Experience with Azure DevOps and Jira. Previous experience mentoring engineers or providing technical leadership within a delivery squad.
