Senior Backend Developer | C# Developer

Senior Backend Developer – C#
Build what the future runs on.

In the world of fintech, speed, scale, and trust define success. In the world of crypto, innovators are our customers. 

We’re looking for an engineer who thrives on solving complex problems in fast-moving environments. An engineer who thinks laterally has solid foundations but is not defined by them. 

This is more than code. It’s architecture for growth. Systems built for resilience and technology that empowers millions.

This company's engineering team is expanding at a deliberate pace, driven by surging demand across global markets. You’ll be joining a group of builders—sharp minds who think beyond the ticket, beyond the sprint, beyond the obvious solution.

Here, you won’t be a cog in a silo. You’ll be hands-on, close to the business leaders, making critical contributions to products trusted by a rapidly growing international customer base.

What you’ll do

• Design, build, and refine backend services and APIs using .NET, MS-SQL, and Docker.
• Shape the future of our stack as we migrate to .NET 8+, ensuring speed, scalability, and reliability at every turn.
• Build scalable RESTful API's
• Collaborate with product managers, engineers, and tech leads to deliver elegant solutions to complex challenges.
• Uphold best practices for security, performance, and resilience in every line of code.
• Troubleshoot, debug, and problem-solve at scale—where the stakes are high and the impact is immediate.

What we’re looking for

• Multiple years of experience in backend development, with mastery in C#, ASP.NET, .NET Framework, and .NET 8+.
• Proven expertise in relational database design and performance tuning.
• A growth and open mindset: curious, resourceful, and unafraid to push beyond the textbook solution.
• Strong critical thinking, someone who thrives when priorities shift and complexity scales.
• Working knowledge of AWS in production, CI/CD & unit testing 
• SQL Server
• Collaborative by nature, with the communication skills to bring clarity in a fast-moving team.
• You'll need a passionate interest in crypto, and any professional or personal experince building out blockchain technologies would be highly beneficial.

Nice-to-haves (not dealbreakers): exposure to blockchain technologies, DevOps/Linux, Node.js, or Typescript.

Why join us

• Competitive salary package (AUD $160K–$180K + super + bonus potential).
• A dynamic fintech in the crypto space—fast-growing, global, and ambitious.
• A team that values curiosity, learning, and shared success.
• Career-defining opportunities to grow as we scale across international markets.
• A culture that is technology at its core and blends solving problems with creativity, with entrepreneurial energy
• An in-office culture that offers a high level of flexibility to work from home when desired and hours that produce outcomes. 

This is where technology meets possibility. If you’re ready to leave behind routine coding and step into a role where your decisions shape real-world outcomes, we’d love to hear from you.

You'll need to be an Australian Citizen, PR holder and/or have the appropriate working VISA's to live and work in Australia.
