Description

Eftsure is a fast-scaling SaaS (Software-as-a-Service) Fraud Technology platform that protects the B2B payments of Australian businesses by providing real-time vendor (supplier) verification and real-time payment protection. In a world of explosive and evolving cybercrime and payment fraud, we ensure our customers never pay the wrong people! Our vision is to be the Security Standard for B2B payments with continual platform evolution and international expansion. Our mission is to support the Australian business community to transact securely. We are looking for a Senior Software Engineer to join our growing team. Role Summary The Senior Software Engineer at Eftsure is a critical player in our product development process, bringing both deep technical expertise and emerging leadership ability to the table. This role is centred on designing, developing, and maintaining high-quality software solutions that meet the highest standards of efficiency, scalability, and reliability. This position sits within the Customer Portal team, based in our North Sydney office, reporting to the Tech Team Lead in South Africa. As the team is distributed across Australia and South Africa, working hours are adjusted to overlap with the South African team — typically starting between 10:00–11:00 am and finishing around 7:00–8:00 pm Sydney time.

Your contributions will shape the future of Eftsure’s software engineering methodologies - fostering innovation, collaboration, and excellence across teams and technical domains. As a valued member of the Eftsure team, your responsibilities will be to: • Drive Technical Excellence: Lead and mentor more junior engineers, empowering them to reach their full potential while ensuring that all development aligns with the highest technical standards and business objectives. • Architect and Develop Scalable Solutions: Take ownership of designing and implementing robust, scalable software systems that directly contribute to the efficiency and growth of our product offerings. • Collaborate for Impact: Work closely with cross-functional teams, onshore and offshore, to ensure that software solutions are not only delivered on time but also meet or exceed the expectations of all stakeholders, enhancing overall product value. • Lead with Influence: Set the tone for engineering best practices through thoughtful design, technical rigour, and proactive engagement. Contribute to architectural discussions and champion improvements in performance, maintainability, and scalability. What you need to be successful: • Minimum 6 years’ professional experience in software engineering. • Proven mastery in .NET development (mandatory), with hands-on experience in SQL and cloud technologies. • Strong problem-solving and analytical thinking, with the ability to design scalable, maintainable systems. • Demonstrated ability to mentor, influence, and lead by example in a technical capacity. • Excellent communication skills and proven success working with distributed, cross-time-zone teams. • A proactive mindset with a commitment to continuous learning and technical excellence. Experience and Qualifications: • Bachelor’s degree in Computer Science, Software Engineering, or a related field preferred but not essential. • Relevant certifications showcasing advanced technical expertise or specialisation are highly regarded. Benefits • Birthday Leave • Floating Cultural Holidays • A Day of Leave to Support a Charity • Annual Reimbursement of $250 for Wellness Expenses • Additional Training and Flexible Working Arrangements If this sounds like you, we’d love to hear from you.
