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
Working at Atomi
- Tailored flexibility: Enjoy work-life balance with hours that adapt to your needs, whether for university, family or personal time.
- Generous leave: Experience unlimited paid leave options as a permanent team member.
- Location Independence: Work from Sydney, interstate or wherever you find inspiration.
- Growth and development: Use ongoing opportunities to improve your skills and expand your knowledge.
- Holistic wellbeing: Benefit from a comprehensive employee assistance program subscription and additional wellbeing leave, supporting your best self.
- Parental support: Enjoy 14+ weeks of paid parental leave.
- Work with the best: We know you want to work alongside the best, so we work hard to hire only the best.
- Regular social in-person and remote events: Including team sports competitions, trivia nights and annual events.
- Atomi access: Enjoy free Atomi services for you and your family.
- Onsite teams: Our Sydney office is ideally located in a central setting with cafes, shops and public transport nearby.
How to apply
Ironically for an education company, we’re not huge sticklers for qualifications. We’re more interested in how your skills and experience can contribute to our team. Make sure to include links to any relevant projects, like your portfolio, writing, GitHub, etc. - whatever helps us understand what you're good at, what you're passionate about, and why you’d be a great fit at Atomi.
We also know great people come from all kinds of backgrounds, so even if you don't meet all the requirements we've listed, you should still apply.
Please note: You'll need Australian working rights for this role.
