Job Description

About Us

Tiimely is a platform technology company leading the future of financial assessment through predictive and explainable AI, and configurable, API-led solutions. Our proprietary technology automates financial assessment and credit decisioning, enabling faster, more accurate outcomes across a range of use cases, and is licensed by large banks, fintechs, ASX-listed brands and our own in-house retail business, Tiimely Home.

Headquartered in Adelaide with a national team of 120, we're on a mission to transform how Australians access credit through cutting-edge technology and a human-first approach. As a certified B Corp, our values — Time to be Human, Time to Take Responsibility, Time to be Transparent, and Time to Build Good Bonds — shape how we build products and how we work together.

The Position

At Tiimely, we need engineers who can independently deliver high-quality backend software within a regulated fintech environment.

As an experienced Software Engineer, you'll contribute to the design and delivery of secure, scalable backend services and integrations across our web, integration, and credit decisioning platforms. While primarily backend-focused, you'll collaborate with Front End Engineers to ensure seamless integration and cohesive product delivery.

You'll work within a domain-rich environment as our platform processes real credit applications in a regulated financial services context. Understanding how your code supports lending workflows, compliance requirements, and customer outcomes is part of what makes this role distinctive.

Your responsibilities will include:

• Design and implement backend services and APIs that power Tiimely's platform, using established architectural patterns and coding standards.
• Deliver backend components and features end-to-end, ensuring scalability, performance, and maintainability.
• Write clean, secure, and maintainable code that contributes to engineering quality standards.
• Own the quality of your work through solid unit, integration, and API contract test coverage.
• Collaborate with Test Engineers to define appropriate testing strategies and quality gates.
• Collaborate with Front End Engineers to ensure backend APIs are designed for usability and clarity.
• Identify and resolve technical issues, performance bottlenecks, and reliability risks.
• Own CI/CD contributions for your services, ensuring safe and repeatable deployments.
• Implement secure coding standards and comply with financial services regulatory requirements.
• Participate fully in code reviews, driving continuous improvement in code quality.
• Contribute to technical documentation including design specs and architectural decision records.
• Participate actively in Agile ceremonies, planning, and estimation.
• Stay current with emerging technologies and industry best practices, sharing knowledge across the team.

What We're Looking For

Required

• Strong proven experience in backend software development within modern product engineering environments.
• Deep expertise in .NET Core (MVC and Web APIs), C#, MSSQL, and event-driven architecture.
• Solid understanding of SOA, Microservices, and distributed systems.
• Experience designing and maintaining RESTful APIs and integration services.
• Experience working with AWS or similar cloud-native architectures.
• Solid understanding of clean code principles (SOLID, DRY, DDD) and secure coding practices.
• Experience with CI/CD workflows and deployment automation.
• Thorough debugging, diagnostics, and performance optimisation capability.
• Experience working in Agile environments and contributing to planning and estimation.
• Experience supporting peers through code reviews and collaborative development practices.
• Ability to understand and apply financial services domain constraints to software design.

Desirable

• Experience with highly configurable or rules-based systems (e.g., credit decisioning).
• Experience working within regulated financial services or compliance-heavy environments.
• Familiarity with frontend frameworks (React / Next.js) sufficient to support integration work.
• Experience leveraging AI tools and technologies to enhance development productivity, code quality, or problem-solving.
• Familiarity with Python for scripting or data-related tasks.
• Experience contributing to architectural discussions and technical design.

What's In It For You?

• Competitive remuneration package with employee share plans that reward individual and company success.
• Flexible working arrangements, including hybrid options.
• Ongoing learning and development to support your professional growth.
• A modern office environment designed for a scaling fintech.
• A supportive and inclusive team culture backed by our B Corp certification and values-driven approach.

If this sounds like you, we'd love to hear from you. Even if you don't tick all the boxes, we encourage you to apply.
