Job Description

At Silentium Defence, we’re driving innovation in passive surveillance technology across critical Defence and national security applications. Our systems enable covert, cost-effective, and comprehensive situational awareness — and we’re growing fast.

We’re looking for a Technical Writer who enjoys turning complex technical information into clear, accurate, and user-friendly documentation. This is a great opportunity for someone with technical writing or publications experience — or someone with hands-on maintenance experience who wants to help shape the content that supports end users in the field.

Your Opportunity

As a Technical Writer at Silentium Defence, you’ll work closely with internal engineering teams to support the development, update, and maintenance of technical publications for our systems and equipment. You’ll help ensure technical manuals remain current, controlled, and
practical for operators and maintainers. Reporting to the Support Lead, you’ll contribute to documentation quality, support review and approval workflows, and help keep training materials aligned with technical manual updates.

This role offers the chance to grow your capability in a highly technical, mission-focused
environment while building autonomy and expertise over time.

In This Role, You Will

• Work with engineering teams to create and refine technical manual content
• Update manuals to reflect the latest system changes
• Coordinate updates to illustrations and graphics with external providers
• Partner with hardware and software SMEs to document operator and maintain
  instructions
• Support the review and approval of technical manuals
• Assist with keeping training materials aligned to technical publications
• Help maintain configuration control over source files and documentation data
• Identify opportunities to improve documentation, processes, and customer outcomes
• Occasionally support local field deployments when required

About You

You’re organised, detail-focused, and comfortable working with technical information. You communicate clearly, work well with others, and take pride in producing accurate, usable documentation. You may already have experience in technical writing, publications, or
configuration-controlled environments — or you may come from a hands-on technical or maintenance background and be ready to apply that knowledge in a new way.

You’ll likely bring:

• Experience in publications authoring, technical writing, and configuration management
• Experience using publishing software and tools
• Strong written communication and attention to detail
• A collaborative approach and willingness to learn
• The ability to obtain and maintain an Australian Government security clearance

Highly desirable:

• Adobe InDesign experience
• A qualification in writing, authoring, journalism, or a related discipline
• Early-career technical support or maintenance experience
• Exposure to Defence, RF, radar, or sensing systems

Why Join Silentium Defence

• Contribute to technology that supports critical Defence capability
• Work alongside engineers and technical specialists in a growing team
• Build your experience in a purpose-driven, highly technical environment
• Help create documentation that improves usability for real-world end users

Application Eligibility

Due to the nature of our work within the Defence industry, applicants must be Australian Citizens and eligible to obtain and maintain defence security clearance. Only applicants who meet these mandatory requirements will be considered.
