Our culture is people-first and purpose-driven. We’re a down-to-earth, values-led team with offices in Sydney and Melbourne, and a growing presence in Manila. We genuinely enjoy working together, whether we’re solving tough tech problems, brainstorming creative solutions, or grabbing a coffee between meetings. Curiosity is encouraged. Collaboration is second nature. We value excellence, not ego, and back each other to do great work without micromanagement. With low politics and high trust, it’s a place where delivery people, designers, and engineers genuinely connect, and where everyone has a voice, space to grow, and a little fun along the way. Job Description As a Senior .NET Backend Developer at Bilue, you’ll be a key player in delivering high-quality, scalable, and secure backend solutions for our clients. Working in Agile, cross-functional teams, you’ll collaborate closely with designers, frontend engineers, delivery managers, and client stakeholders to create products that solve real problems and provide exceptional user experiences. This is a hands-on role, ideal for someone who thrives on building robust, performant APIs and backend services, while also mentoring others and contributing to a culture of technical excellence. Key Responsibilities Collaborate with Clients: Partner directly with clients and stakeholders to understand requirements, define technical solutions, and provide expert backend guidance.

Technical Leadership: Mentor and support other developers, conducting code reviews and fostering a culture of quality and continuous improvement. Agile Delivery: Actively contribute to sprint planning, daily stand-ups, and retrospectives, ensuring smooth, iterative delivery of client projects. Testing and Quality: Write clean, testable, and maintainable code, supported by automated testing and CI/CD pipelines. Problem Solving: Troubleshoot complex backend issues and propose scalable solutions, with a focus on delivering value to clients. Continuous Improvement: Contribute to architectural decisions, best practices, and tooling improvements to keep the tech stack modern and efficient. Qualifications 6+ years of backend development experience, with deep expertise in .NET (C#). Proven experience designing and building RESTful APIs and microservices. Familiarity with cloud platforms (AWS or Azure), including deploying and managing backend services. Solid understanding of SQL and NoSQL databases, with experience optimising data storage and retrieval. Strong experience working in Agile teams, contributing to collaborative planning and iterative delivery. Committed to writing high-quality, maintainable code with a focus on performance and security. Experienced in CI/CD pipelines and modern DevOps practices. A proactive communicator who is confident engaging directly with clients and stakeholders. Passionate about mentoring and supporting the growth of other developers. Additional Information Life at Bilue People-first focus: We’re committed to delivering exceptional outcomes for our clients, but we know it starts with our people. You’ll join a values-led team that’s collaborative, curious, and genuinely cares about doing great work, together. Connection that counts: From monthly anchor days and team lunches to our annual offsite, we create intentional moments to connect, collaborate, and celebrate. These aren’t just fun perks — they’re part of how we work and grow together. Flexibility that works: We offer hybrid working, with 1–2 days per week in the office. It’s a balance that gives you the space to do your best work, while still creating time to connect and build strong relationships in person. Strong internal communities: We actively foster internal communities across tech, design, delivery, and beyond, giving you plenty of chances to connect, share knowledge, and learn from your peers.
