What you’ll be doing We’re migrating legacy PHP systems to a scalable, cloud-native architecture on .NET, across multiple teams, with a tight delivery timeline.

You’ll be working hands-on as part of that migration – translating real business logic correctly, shipping production code, and helping the team get the details right under pressure. The Senior Engineer will design and deliver technical solutions that meet business requirements. They will embody Reapit’s core values of Trust, Collaboration, Innovation, Excellence, and People. Key Responsibilities: Planning and Requirement Analysis: Collaborate Across Departments : Work closely with product managers, quality assurance, and other departments to refine technical requirements and contribute to solution design.

Requirement Analysis and Estimation : Contribute to analysing technical requirements, conducting research, and estimating effort for planned work. System Design: Technical Design and Implementation : Develop technical designs that meet business requirements and architectural standards, ensuring security, scalability, performance, and maintainability. Implementation: Code Development and Review : Actively write code and participate in the code review process, upholding and contributing to coding standards.

Testing and Validation : Perform rigorous testing and validation of solutions to ensure the quality of deliverables. Documentation : Develop and maintain accurate documentation for engineering projects, ensuring all necessary materials are produced and maintained for future reference and compliance. Project Delivery: Agile Participation : Actively participate in agile ceremonies, including daily stand-ups, sprint planning, retrospectives, and reviews.

Project Delivery : Contribute to delivering projects on time and to the required quality standards through strong technical execution, collaboration, and ownership of assigned work. Maintenance: Technical Guidance : Provide technical guidance and support to team members through collaboration, code reviews, and sharing best practices. Continuous Improvement : Identify and implement opportunities to improve performance, maintainability, and engineering effectiveness.

Incident Management : Contribute to incident investigation and resolution, support clear stakeholder communication, and help identify follow-up improvements to reduce recurrence. Who we're looking for At Reapit, we prioritise hiring individuals who share our values and possess the right attitudes and behaviours for success. Whilst some of the listed requirements may be important, don’t worry if you don’t meet all of them, we’d still like to hear from you.

Qualifications and Experience: Bachelor’s degree in computer science, engineering, or a related field. 7+ years in back-end software development with .NET/C# - Essential. Experience designing and building RESTful APIs and backend services, ideally with ASP.NET Core - Essential. Front-end web application experience, ideally with React, is favourable but not required. Experience working with distributed teams. Experience contributing to the migration or rewrite of a legacy system into a modern language or framework (e.g.

PHP to .NET, or an equivalent cross-stack migration) – you should be able to describe a specific piece of legacy logic you had to translate, and what made it tricky to get right. Experience incorporating agentic AI tooling into development, ways of working, and delivery. Technical Skills: Strong proficiency in .NET/C# for backend development, including experience with ASP.NET Core, Entity Framework, and MySQL. Knowledge of relational and non-relational databases, with experience in MySQL and ORM tools such as Entity Framework.

Understanding of distributed systems (ideally microservices, event-based architecture). Experience with testing methodologies (unit/integration/E2E testing, mocking, shift-left). Proficiency in CI/CD pipelines and build tools. Exposure to public cloud platforms (preferably AWS) and familiarity with IaC tools like CloudFormation, CDK, and Docker. Familiarity with agentic AI development, with an emphasis on improving developer productivity (e.g., coding assistants, agentic workflows for test generation/debugging, documentation and runbook automation, and evaluation/guardrails for safe adoption).

Understanding of SOLID design principles. Comfortable reading and reasoning about legacy PHP codebases – you don’t need to write new PHP, but you do need to understand existing business logic well enough to translate it correctly into .NET, including edge cases that aren’t documented anywhere. What your impact and success looks like We expect your success and impact in the early stages of your career with us to look something like this: As this is a contract engagement, we’re looking for someone who can ramp quickly and deliver from early on.

In addition to the milestones below, you should expect to: Within 2 weeks: Have a working local environment, be reading the codebase unsupported, and be asking informed technical questions in code review and planning sessions. Within 1 month: Be shipping production code independently on moderately complex tickets, with minimal need for senior support. Within 6 weeks: Be working independently on complex features end-to-end, and delivering measurable value against the engagement’s priorities without requiring extended ramp-up support.

Within 3 months: You will have a strong command of the core technology stack and migration patterns in use, and will be able to spot logic that’s likely to be misread or mistranslated before it becomes a production issue. You will be independently owning complex features end-to-end, from design through implementation and testing, with minimal senior oversight. You will be raising informed, evidence-based suggestions on architecture, tooling, or process – even if the final call sits with the Staff Engineer or Principal.

You will be holding a consistently high standard in your own code, reviews, and testing – setting an example other engineers on the team notice and follow. You will be working closely with Product to clarify requirements and flag scope or sequencing risks early. We operate a Flexible Working Policy and you are free to determine where you work from, be that from home or in the Sydney or Brisbane offices, and how often but we certainly recommend a balance.

Don't tick all the boxes? Neither do we We care about our industry and want it to become a more inclusive and diverse place to work. So, we’re driven by hiring not only by experience and relevance for the role but by sharing our values and the right attitudes and behaviours for success. We are committed to Equal Employment Opportunity through attracting and retaining a complementary team of employees and building an inclusive environment for all.

We feel we have an empowering environment where everyone is supported and respected, and we want you to feel this too. We welcome new ideas, thinking and approaches, whilst listening to all our employees. “We are a 2025 Circle Back Initiative Employer – we commit to respond to every applicant.”
