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 Our stack Backend – Node.js, TypeScript, Turborepo Frontend – React, Next.js, React Native Infrastructure – Cloudflare (Workers, Queues, KV) Data – Prisma, PlanetScale, ClickHouse Testing & CI – Vitest, Playwright, GitHub Actions Observability – Datadog, Sentry, OpenTelemetry Experimentation – Statsig 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.
