Build the products and platform that power customer-first monetisation.
Thanks is building a customer-first monetisation platform that delivers sustainable growth – for advertisers, publishers, and customers. We’re operating at scale today and entering a phase where execution quality, speed, and sound technical judgment matter more than ever.
We’re hiring a Senior Engineer to design and ship meaningful product improvements across our platform. You’ll independently drive work end-to-end, bring clarity to complex decisions, and consistently deliver at pace in a high-trust, high-impact environment.
This role is hands-on, product-minded, and execution-focused.
What you’ll do
-
Ship impactful features end-to-end: Design, build, test, and deploy frontend and backend functionality across our TypeScript / Node / React stack.
-
Design thoughtful solutions: Independently design technical solutions within our architecture, clearly communicating trade-offs while balancing speed, scalability, and long-term impact.
-
Own meaningful surface area: Take responsibility for a subsystem or domain area, ensuring quality, maintainability, and steady improvement over time.
-
Bring product thinking into engineering: Challenge scope when needed, contribute to sequencing decisions, and ensure we’re solving the right problems in the right way.
-
Maintain high engineering standards: Write clean, well-tested code, participate actively in code reviews, and contribute to a culture of contextual quality.
-
Support production reliability: Troubleshoot issues, resolve bugs, and ensure performance and stability across live systems.
-
Collaborate openly: Communicate clearly about progress, risks, and trade-offs, contributing to a high-trust, feedback-oriented engineering culture.
Requirements
What we’re looking for
- Strong experience building production systems using TypeScript, Node.js, and React
- Ability to independently design scalable solutions and clearly communicate technical trade-offs
- Strong software design fundamentals and system thinking
- Comfort owning features from problem definition through to production
- Pragmatic judgment – you balance ideal architecture with shipping value
- Comfort operating in ambiguity and actively creating structure where it’s missing
- High emotional intelligence and strong communication skills
- Strong internal drive – you take pride in your craft and care deeply about the quality and impact of what you ship
- Uses AI thoughtfully to augment problem solving and delivery – accelerating exploration, debugging, and implementation while maintaining high standards for quality, correctness, and ownership
- A genuine ownership mindset – you take responsibility for outcomes and follow through
Nice to have
- Experience building and scaling production systems in product-led startup or scale-up environments
- Exposure to adtech, marketplaces, or performance-driven platforms
- Familiarity with Cloudflare (Workers, Queues, KV)
- Exposure to data systems such as ClickHouse or similar OLAP platforms
- Understanding of experimentation frameworks
- Experience contributing to architectural discussions in growing systems

Benefits
Why Thanks?
At Thanks, we’re building a customer-first monetisation platform that delivers growth without compromise – for advertisers, publishers, and customers alike. We power growth for the world’s leading brands, delivering tens of millions of high-value “thanks” moments every month.
What makes this role different:
Real ownership: You’ll drive meaningful product work end-to-end, with trust and autonomy.
Impact you can see: Your work directly influences performance, reliability, and growth.
High standards, low ego: We value thoughtful decisions, clear communication, and strong follow-through.
Attractive compensation: Including worthwhile equity.
Flexibility with intent: We’re Sydney-headquartered and value in-person collaboration, ideally a couple of days per week. That said, we care more about leadership, impact, and outcomes than rigid rules - and we’re open to exceptional candidates across Australia’s east coast.
We’re building something deliberately – not copying what already exists. If you’re excited by product-led engineering and solving complex problems at pace, we’d love to hear from you.
Let’s build something extraordinary.
