Job Description
Imagine joining a team building the backbone of a platform that’s redefining how global enterprises manage their most complex workflows - from intake through to reporting and insights.
You’d be joining a business with serious backing from Australia’s top investors that is scaling fast. After strong traction across Asia and the US, they’re now doubling down on enterprise scale - and looking for a senior engineer to help architect that next evolution.
The product is already in-market and growing fast; now it’s about reimagining its architecture to handle the scale and sophistication of large enterprise clients. This is a rare chance to get in at the inflection point - helping design the systems, subsystems, and patterns that will power the next chapter of the platform.

This is a rare chance to get in at the inflection point - helping design the systems, subsystems, and patterns that will power the next chapter of the platform.
What’s in it for you?
- Shape the architecture - take a core role in evolving an MVP into a scalable, enterprise-grade platform.
- Own key subsystems - design and implement modules for task management, calendar, search, and document retention.
- Real technical depth - build in a backend-heavy TypeScript stack using Node.js, Postgres, Redis, and AWS.
- Autonomy and impact - work directly with a technical lead who values ownership, clarity, and thoughtful decision-making.
- Cross-functional collaboration - partner closely with product and data teams to define and deliver features that customers love.
- Modern engineering culture - Kanban over ceremony, async-first communication, and hybrid flexibility with a fun, grounded team.
- Flexible and rewarding - hybrid work, learning & development budget, generous equity, and overseas company retreats!
- Experienced backend-leaning full stack engineer with solid fundamentals in TypeScript + Node.js
- Confident in system design and architecture, especially scaling and migrating live systems
- Strong communicator - clear, structured, and comfortable collaborating across teams
- Thrive in ownership-heavy environments where you help shape both the product and the tech
- Balanced mindset - understand trade-offs, clarify before building, and always think about the “why” behind what you’re building
- Bonus: exposure to multi-tenant SaaS, Elastic/OpenSearch, or serverless environments
- TypeScript, Node.js, React
- PostgreSQL, Redis, BullMQ
- AWS, Serverless (in progress)
