Senior Full Stack Engineer

About Gradeo

Gradeo is a fast-growing edtech specialising in online assessment. We’re on a mission to transform how educators assess and how candidates sit assessments through technology. We combine rigorous, quality-assured test instruments with cutting-edge technology.

Since launching in March 2025, almost 400 schools now choose Gradeo for their online exams and exam preparation. We operate an end-to-end assessment platform that is entering a critical evolution phase.

We are looking for an ambitious, high-agency Senior Engineer to join our lean team. This is a role for a builder who wants to ship code that matters, take ownership of complex technical challenges, and see their work used by thousands of students immediately.

The Role

We are scaling to meet the demands of our upcoming feature roadmap and platform upgrade. In this hands-on position, you will work directly with the Founder and the technical team to accelerate delivery and stabilise our infrastructure.

You will be responsible for bridging the gap between our established platform and our new architecture. You won't just be picking up tickets; you will be optimising our "path to production," hardening our security, and ensuring that we ship robust, testable code every sprint.

This is currently a fully remote role (strong preference for Sydney-based) with the autonomy to define how you work. We are looking for someone who values impact over over-engineering and "getting it done" over bureaucracy.

Key responsibilitiesHands-On Development & Delivery

• Ship high-quality code across the full stack. You will work in TypeScript with NestJS, Next.js, Postgres, Temporal.io, Socket.io, PostHog, Azure and more.
• Contribute to both backend and frontend development. We value 'T-shaped' engineers who are comfortable across the stack, even if you lean towards one side.
• Drive the feature roadmap by translating business requirements into working software.
• Take ownership of critical features from design to deployment, ensuring they are robust, scalable, and user-centric.

Architecture & Code Quality

• Help architect the integration between our current platform and new modules, ensuring seamless data flow and user experience.
• Champion code hygiene. You will write clean, documented code and help maintain a repo that is easy for others to work in.
• Ensure rigorous testing protocols are in place for mission-critical functions (e.g., exam saving logic).

Security & Compliance

• Fit into a "Security First" mindset. You understand the importance of data sovereignty and PII protection in the education sector.
• Support our compliance roadmap to ST4S by maintaining up-to-date technical documentation.

About you

• You are a true full stack engineer:  You understand how to build complex applications that perform at scale.
• You love simple and learning: You have a love of simple, easy to understand, easy to test code. You will always be curious about new techniques for the craft of software engineering, and teaching what you learn to others.
• You are purpose-driven: Prior experience in education is not required, but we’re looking for someone who believes technology can transform assessment and learning.
• You are ambitious, proactive & autonomous: You thrive in small, fast-paced environments where you are trusted to manage your own time and output. You don't need to be micro-managed.
• You communicate clearly: You can explain technical risks to non-technical stakeholders and collaborate effectively in a remote setting.
• You meet our compliance obligations: You must hold or be willing to obtain a Working With Children Check, and pass a NSW Police Background Check.
