Introduction
The Developer role at the Department of Customer Service is a technical delivery role with a stream-based application structure. It suits applicants who can code confidently, work with modern development practices, and back up their technical claims with clear evidence of delivery and problem-solving. You can view the official job ad here.
If you want to understand how to apply for Developer, the application needs to do two things at once. It needs to show core engineering capability across programming, version control, testing, and analysis, and it also needs to make your preferred stream clear. For this role, the streams are CadNSW Developer and ESRI / Spatial Developer.
NSW Government applications are assessed against both the instructions and the role requirements. That means your cover letter and resume need to follow the stated limits and also prove, through practical examples, that you can build, solve problems, and deliver work in the stream you nominate.

NSW Government application requirements
Application requirements are the written materials you must submit so the panel can assess both compliance and technical fit. In technical recruitment, those documents matter because they show how clearly you can explain your work as well as what you have actually delivered.
Application requirements for Developer
For this role, you need to submit a two-page cover letter that names your preferred stream and a resume of up to five pages. That means the cover letter has a specific job beyond general introduction. It needs to show why your background fits the stream you are nominating and which parts of your experience are most relevant.
The resume gives you more space for project detail, technical stack, and achievements. The cover letter should focus on technical relevance, problem-solving, and stream fit. This role also has two clear eligibility conditions: you must be an NSW resident or in the process of relocating to NSW, and you must hold work rights that cover the full duration of the fixed-term role. Read the full job ad again before submitting so your stream choice and examples stay aligned to the role.
NSW Government candidate requirements
Candidate requirements are the technical skills and work-based strengths the panel wants to see supported with evidence. For this role, your examples should show both core engineering capability and fit to the preferred stream.
Candidate requirements for Developer at the Department of Customer Service
| Requirement or capability from role | How to demonstrate it |
|---|---|
| Programming capability in the listed languages | Use examples that show real delivery in relevant languages such as Python, Node, Java, JavaScript, TypeScript, or C#. Focus on what you built and the technical decisions you made. |
| Git and testing | Show that you work with version control and testing as normal parts of delivery, not as add-ons. Explain how they supported quality or release confidence. |
| Analysis and problem-solving | Use an example where you diagnosed an issue, improved a system, or solved a technical problem with a clear outcome. |
| Stream-specific capability | If you are nominating the CadNSW Developer stream, show AWS delivery, cloud services, CI/CD, or modernisation work. If you are nominating the ESRI / Spatial Developer stream, show ESRI technologies, ArcGIS Pro, spatial APIs, spatial data services, or geospatial system experience. |
Example application structure for Developer
This application requires a cover letter and resume because the shortlist confirms both documents and gives clear page limits. The maximum confirmed limits are a two-page cover letter and a five-page resume, so the cover letter needs to stay selective and focused on the stream you want. The table below shows how to organise the cover letter so it supports the resume rather than repeating it.
| Cover letter section | What to include |
|---|---|
| Opening paragraph | Name your preferred stream and explain the combination of technical delivery, programming capability, and problem-solving that makes you a strong fit. |
| Core development capability | Use one paragraph to show relevant programming work, including the technologies you used and what you delivered. |
| Testing, Git, and engineering discipline | Use a second paragraph to show your development practices, collaboration, and quality controls in real work. |
| Stream-specific relevance | Use a third paragraph to show AWS or ESRI and spatial capability, depending on the stream you are nominating. |
| Mandatory requirements | Confirm the binary eligibility conditions around NSW residency or willingness to relocate to NSW and valid work rights for the duration of the role. |
| Closing paragraph | Finish with a concise statement reinforcing your technical fit and readiness to contribute in the nominated stream. |
What the panel will want to see in your examples
- Specific delivery work rather than a list of technologies only
- Clear technical decisions and problem-solving
- Evidence of disciplined engineering practices
- Strong fit to the nominated stream
- Results that show practical impact
