Job Description
More than a job
There's nothing better than knowing the work you're doing matters and makes a genuine difference.
We're pretty lucky that, at Mosh & Moshy, this is the norm rather than the exception.
Our engineering team's growing and we're hiring multiple Senior Software Engineers, with a particular focus on growing our Sydney-based team.
We're open to experienced backend specialists as well full-stack engineers whose strongest capability sits on the backend.
While the shape of each role may vary, they all share a strong foundation in building reliable APIs, services and product capabilities that support our digital health platform.
As passionate technologists with an appreciation for clean code and fault tolerant systems - we believe in leveraging different perspectives and backgrounds because that makes our team and product stronger.
We look for teammates who are:
Curious and aim to understand things deeply.
Respectful and inclusive.
Comfortable sharing the grunt work.
What you'll do
As a Senior Software Engineer, you'll:
Design, build and own APIs and services that form the core building blocks of our platform
Deliver reliable product capabilities from technical design through to production, monitoring and ongoing improvement
Write clean, well-tested and maintainable code, conduct thoughtful code reviews and produce clear technical documentation
Take the lead on solving complex technical challenges and making pragmatic, data-informed engineering decisions
Help evolve our architecture by decomposing monolithic applications into well- bounded, domain-driven services
Design and build resilient distributed and event-driven systems
Contribute across the stack where appropriate, working closely with Product, Design, Data and other engineers to deliver high-quality customer experiences
Build and improve deployment, testing and development practices that help the team release confidently
Contribute to automated regression, performance and resiliency testing to keep production stable and fast
Drive operational excellence through observability,



runbooks and active participation in incident response and resolution
Explore new and emerging technologies, clearly documenting your findings and recommendations
Proactively identify and champion improvements to our engineering practices and standards
Mentor other engineers, model best practice and help raise the technical bar across the team
Support the continued growth of our engineering team through interviews, onboarding and knowledge-sharing
What you'll bring
Around 6+ years of software engineering experience designing, building, deploying and scaling API-driven systems
Strong backend engineering capability and fluency in at least one modern programming language, such as Go, Java, Kotlin, Python or TypeScript
Strong experience designing and operating production workloads in a public cloud workplace, particularly AWS
Extensive knowledge of cloud architecture principles and patterns
Strong knowledge of distributed systems, fault tolerance and resiliency patterns
Strong knowledge of API best practices, including contract-first design, versioning strategies and backwards compatibility
Experience designing and working with event-driven architectures, including messaging, streaming and eventual consistency
Strong experience with Linux and containerised environments using technologies such as Docker and Kubernetes
Hands-on experience with Infrastructure as Code and production observability practices
Solid working knowledge of relational databases such as PostgreSQL
A track record of writing clean, well-tested and maintainable code, with demonstrated technical initiative
The ability to balance technical quality with pragmatic product delivery
Healthy curiosity,



strong autonomy and a deep sense of accountability for your work
A genuine drive to grow as an engineer and raise the standard of those around you
For our full-stack opportunities, you'll also bring meaningful experience building modern web applications and delivering intuitive, high-quality customer experiences.
You'll remain comfortable spending a significant portion of your time working across backend services, APIs and data.
Experience that would be valuable
You don't need to bring every one of these, but experience across any of the following would be highly regarded:
Contract-first API tooling such as OpenAPI or AsyncAPI
Messaging and streaming technologies such as Kafka or SNS/SQS
Terraform or equivalent Infrastructure as Code tooling
Observability tooling such as Prometheus and Grafana
CI/CD infrastructure and deployment automation
Performance, regression and resiliency testing
Breaking down or modernising large monolithic applications
Working within healthcare, fintech or another regulated environment
What's on offer
We support a mix of in-office, hybrid and remote working across Australia.
With several positions available, we're open to exceptional candidates nationwide; however, we're looking to grow our Sydney-based engineering presence and will prioritise candidates who can regularly collaborate from our Surry Hills office.
If you're Sydney-based, you'll typically spend three days (M,W,F) in the office, with flexibility to work from home.
You'll also enjoy:
Access to on-demand training and development
Up to 16 weeks of paid parental leave
Two additional days of annual leave each year
Purpose leave for mental health or learning and development
EAP and wellbeing programs
Better, together
We value diversity of thought, background, and perspective.
If you're excited about this role but don't meet every requirement, we still encourage you to apply.
Come help us shape the future of healthcare at Mosh & Moshy!
