Sydney | 5 days in the office | Big Wave Digital Let’s not sugarcoat it. If this system breaks… people notice. Not because a button is misaligned. Because
money is wrong. The Company You’ll be joining a scaling fintech with real volume flowing through its platform every day. This is not theoretical.
- Real transactions
- Real partners
- Real payouts
- Real consequences
They’re building out the infrastructure that powers how revenue moves through the business. And right now… it needs to level up.
The Mission You own the systems that decide: 👉 Who gets paid 👉 How much they get paid 👉 And whether it’s right This is the engine behind partner growth, referrals, and revenue distribution. High volume. High complexity. Zero room for error.
What You’ll Actually Do You won’t sit in one lane. This is
true full-stack engineering. You will:
- Build and evolve systems that handle financial calculations at scale
- Design async processing pipelines that don’t fall over when things get messy
- Work with real-time and near real-time data streams
- Build data-heavy React interfaces that make complex financial data usable
- Own reliability — not just uptime, but correctness
- Design data models where getting it wrong actually matters
You’re not just shipping features. You’re building systems the business
depends on to function. The Kind of Problems You’ll Solve
- How do you ensure payouts are correct across thousands of variables?
- What happens when a job fails halfway through processing?
- How do you make complex financial data understandable to a non-technical user?
- How do you design systems that are both fast and auditable?
If those questions interest you… keep reading.
What Matters Here This role is for engineers who like
hard problems with real consequences. You probably:
- Have strong experience across .NET backend + React frontend
- Understand async patterns properly (queues, retries, idempotency)
- Have worked on high-throughput systems where scale exposes flaws quickly
- Care about correctness, not just “it works on my machine”
- Can move across the stack without friction
Bonus if you’ve:
- Built financial systems, payout engines, or affiliate platforms
- Worked in regulated environments
- Dealt with reconciliation, audit trails, or transaction pipelines
The Environment Let’s address it upfront.
5 days in the office. Sydney. Non-negotiable. Because this team:
- Solves problems together, quickly
- Makes decisions in real time
- Works through complexity side by side
This is a
high ownership, high accountability environment. Not a passive one.
Why This Role Exists Because scaling a business is easy… Until the backend that moves money can’t keep up. They need someone who can: 👉 Build systems that don’t break under pressure 👉 Design for failure before it happens 👉 Turn complexity into something reliable
Apply If you like clean UI… This probably isn’t your role. If you like solving problems where:
- The edge cases matter
- The data matters
- And the outcome really matters
Then we should talk.
