We are looking for a hands-on CTO / Technical Co-Founder to help take an existing AI-powered B2B SaaS platform from technically fragile to dependable, commercially ready and scalable.

This is not a conventional salaried role. It is a pre-funding opportunity for someone prepared to invest time and technical leadership in exchange for meaningful equity and founder-level influence.

The opportunity

Our SalesTech platform helps sales reps and managers turn meetings into intelligence, preparation, actions and deal insights.

The product is already live with recording, transcription, summaries, meeting prep, Ask SAM, Tasks, analytics and calendar integrations.

The immediate priority is not to build more for the sake of it. It is to stabilise, simplify and strengthen the platform so we can onboard pilot customers, convert paying customers and prepare for funding.

What you will own

You will:

- stabilise uploads, authentication and performance
- strengthen multi-tenant security, identity and permissions
- improve observability, testing and release confidence
- simplify unnecessary technical complexity
- establish pragmatic engineering discipline
- remain hands-on in the .NET codebase
- develop the existing engineering and QA resources
- help shape product and technical priorities with the founder

What we are looking for You are a commercially pragmatic technical leader who has previously taken an imperfect SaaS platform from unstable to dependable.

Robust experience in:

- SaaS stabilisation and architecture
- .NET / ASP.NET Core
- multi-tenancy,



authentication and RBAC
- APIs and third-party integrations
- databases, migrations and data integrity
- observability, testing and CI/CD
- developing junior engineers
- making technical decisions based on customer value and runway

Experience with Azure B2C / Entra, Microsoft Graph, React, Python, HubSpot, Salesforce and applied AI/LLMs is valuable. We value someone comfortable saying: “We should fix this, not rewrite it.” “This technical debt can safely remain.” “We don't need that complexity yet.”

Equity and commitment

This is currently an equity-only role, with no cash salary until an agreed funding or commercial milestone.

The preferred structure is

- meaningful co-founder equity with agreed vesting
- clearly defined authority and commitment
- transition to full-time CTO after funding
- market-aligned salary after the agreed trigger

This is probably not for you if you:

- need a salary from day one
- default to rewrites, microservices or Kubernetes
- prefer strategy and delegation over being hands-on
- have only worked with large specialist engineering teams
- want the CTO title more than the responsibility

If you have previously inherited a fragile SaaS platform, made it dependable without rewriting everything, and want meaningful ownership in what you build next, we'd like to hear from you. When applying, briefly describe the platform you stabilised, what you prioritised first, what you chose not to rebuild, and the outcome.

- Australia-based candidates only.
