This is a rare opportunity to step into a foundational architecture role within a product-led scale-up entering its next phase of growth.

The platform is live. Customers are active across Australia, New Zealand, and international markets. The challenge now is scale, not in theory, but in production. You’ll own the architectural vision and help translate it into systems that are resilient, secure, and built to evolve.

This is not a passive governance role. You’ll be close to the code, close to the product, and close to the people building it. You’ll shape decisions that materially affect customers, velocity, and long-term platform health, and you’ll help create the technical blueprint for what this company becomes next.

What You’ll Be Doing

- Owning architectural direction across a modern, cloud-native, distributed platform
- Designing, building, and evolving event-driven, serverless systems engineered for scale and reliability
- Leading architectural thinking for recent product initiatives and major platform evolution work
- Staying hands-on with code, reviews, and technical decision-making — not just documentation
- Partnering deeply with Engineering, Product, and Platform teams to turn strategy into execution
- Designing mobile-first and API-first systems that power customer-facing experiences
- Embedding security, privacy, and compliance into the platform by design, not as an afterthought




- Defining architectural standards and patterns that enable speed rather than slow teams down
- Acting as a technical leader and mentor for senior engineers and tech leads, raising the overall bar

What You’ll Bring

- 5+ years’ experience in Solution and/or Enterprise Architecture, ideally within SaaS, product, or scale-up environments
- Strong hands-on AWS experience, including Lambda, API Gateway, DynamoDB, OpenSearch, and serverless architectures
- Practical experience designing and building systems using modern TypeScript / Node.js and React
- A track record of evolving platforms to support growth, performance, and operational maturity
- Strong understanding of security, privacy, and compliance in real-world production environments
- Experience with Infrastructure as Code, particularly Terraform
- A DevOps-first mindset, with exposure to CI/CD, automation, and cloud-native operational practices
- The confidence and communication skills to influence technical direction and align teams around a shared vision

Why Join

- End-to-end ownership of architecture in a fast-growing, product-led business
- The chance to shape systems that will scale across ANZ and global markets
- A high-trust, low-politics engineering culture focused on outcomes, not process
- Hybrid role based in Sydney , with regular in-office collaboration and hands-on team engagement
