Job description

Join Atomi: Reinvent how the world learns.

At Atomi, we're on a mission to unlock human potential by transforming the way students learn and teachers teach. Our platform combines cutting-edge technology with a creative, human-first approach, turning complex ideas into simple, engaging experiences for students, educators, and parents everywhere.

We’re driven by curiosity, humility, and a relentless focus on quality and innovation. At Atomi, your ideas matter, your creativity counts, and your work directly impacts how hundreds of thousands of learners engage with education around the globe.

Come build something remarkable with us.

The opportunity

We're looking for a Senior Backend Developer who understands how solid engineering underpins great product experiences. In this role, you'll join one of our feature squads, taking projects from inception to delivery and owning key aspects of system design, data architecture, and performance.

This role is open to fully remote candidates within Australia or those who'd like to work from our head office in Ultimo, Sydney.

What You'll Do

Design, build and maintain backend systems and services that power our platform. Depending on the squad you join, this could be building new learning experiences, accelerating content authoring, improving classroom management or empowering students and teachers with advanced analytics.

Extend and evolve our backend stack, currently built with TypeScript (NestJS) and PHP (Laravel) microservices.

Collaborate closely with product managers, designers, and fellow engineers to deliver thoughtful, scalable backend solutions

Work with relational and non-relational databases, including MySQL and DynamoDB

Contribute to our GraphQL federation strategy and help integrate backend services into a unified API layer

Ensure performance, scalability, testing, and reliability are first-class concerns in everything you build

Mentor mid-level and junior engineers, helping them grow while leading by example

What You'll Bring to Atomi

Proven experience as a Senior Backend Developer, ideally within a fast-moving product or SaaS environment

Deep expertise in backend development using modern frameworks and tools

Experience with TypeScript and/or PHP. Proficiency in one is essential; experience with both is highly desirable

Solid understanding of relational databases (MySQL) and exposure to NoSQL solutions like DynamoDB

Experience building and maintaining scalable APIs; familiarity with federated GraphQL is a strong plus

A focus on writing clean, maintainable code with an emphasis on performance, testing, and long-term maintainability

A pragmatic mindset—you're just as comfortable diving into legacy code as you are planning for future architecture
