Want to attract the top geoscience talent to your brand?

Rockstaff’s Geoscience Employment Marketing System (GEMS™) is the only free-to-use solution that makes it easy for employers to build their brand with highly-targeted audiences. Our suite of advanced social recruitment strategies helps to attract, nurture and convert candidates, whilst optimising speed, quality and cost of hiring.

If you’re relying on your limited network, ‘post & pray’ job advertising or paying agency placement fees, let us show you a proactive alternative.

The Problem

Lacking a proactive employment marketing strategy leads to an over-reliance on reactive, outdated recruitment solutions, which traditionally create barriers to talent and often force employers to compromise between speed, quality and cost. We call this The Recruitment Trilemma.


Prolonging recruitment processes for business-critical vacancies can cost you lost projects and revenue.


Attracting low-quality applicants wastes time, limits your choices, and can lead to poor retainment of staff.


Overspending can lead to poor return on investment, particularly if you don’t retain a candidate long-term.

  • Paying commission-based placement fees is rarely cost-effective.
  • Sales-based approach often negatively impacts the candidate experience.
  • Difficult to trust as their dependence on commission incentivises dishonesty.
  • LinkedIn Networking is very cost-effective, but it requires a large investment of time.
  • LinkedIn InMails are very time-consuming, easy to spam, and expensive if you aren’t receiving positive responses.
  • LinkedIn Job Ads can quickly produce applicants, but ‘pay-per-view’ listings can become very expensive and quality is often poor.
  • ‘Post & pray’ advertising has poor predictability and often low ROI.
  • Provide little exposure to passive (typically higher-quality) candidates.
  • Typically overwhelm hiring teams with low-quality applicants.
  • Organic social media strategies are cheap but difficult to gain traction with.
  • Hard to reach your target audience because they lack the profession-based targeting capabilities of LinkedIn.
  • Hiring teams are typically not experts in social media marketing, which makes it difficult to create synergistic strategies.

Geoscience Employment Marketing System (GEMS™)

Unlike traditional solutions, our GEMS™ removes the barriers to talent and helps employers proactively optimise their speed, quality and cost of hiring, without compromise.


Tell Your Story

Branded landing pages help to increase discoverability, convey your Employee Value Proposition (EVP), showcase employee testimonials, advertise job opportunities, and more.

Grow Candidate Followers

If candidates follow your profile, they are notified of new job adverts and their profiles become accessible to you, even if they choose to be hidden from public search results.

Build Custom Audiences

Pinpointing your target audience is crucial to cost-effective marketing. We can build you highly-targeted custom audiences that you can deliver relevant adverts to across multiple social media channels.


Distribute Job Adverts Or Content

We remove barriers to talent by letting employers advertise jobs for free, instantly distributing Google-Optimised (SEO) job adverts to your followers. Alternatively, if you’ve got content you’d like to share, we can distribute that to your custom audiences.

Reach Your Audience’s Newsfeeds

Reliably place promotional content on the newsfeeds of your custom audience’s social channels and drive high-quality traffic to your employer landing page, job adverts or custom content.

Incentivise Viral Marketing

Your target audience likely has similarly-skilled talent in their network. We can incentivise engagement, such as likes and shares, on social media to help you reach second-degree networks.


Engage Candidates Directly

Engage and nurture talent directly from our growing library of contactable candidates (for confidentiality, their visibility is optional). For convenience, we’ll even auto-match well-suited candidates to your job adverts!

Stay Front-Of-Mind

Your first engagement won’t always catch candidates at the perfect time. But you can stay front-of-mind by retargeting social media audiences of pre-nurtured candidates who have previously shown an interest in your brand.

Advert Sequencing

You wouldn’t propose on the first date, and recruitment isn’t any different. Sequencing adverts will nurture candidate relationships by gradually increasing familiarity with your employer brand. This also helps to reduce candidate dropout rate.


Capture Candidate Leads

Review, shortlist and decline applicants from your dashboard’s Applicant Tracking System (ATS). Or if you prefer to use your own ATS, you can choose to receive applications via email or redirect candidates to external URLs.

Speed Up Filtering Processes

Use pre-application questionnaires to save employee-time by making it easier to filter applicants based on their responses to pre-screening questions for each job advert.

Export Applicant Data

Once candidates have applied to your job, you can mass-export the applicant data as individual PDF or CSV files and upload them to your own ATS.


Measure Performance

Measure the success of your employer landing pages or job adverts with key performance metrics, such as number of visitors or shortlisted applications.

Improve With A/B Split Testing

We use a data-driven approach to A/B test and optimise your adverts to maximise the engagement they receive and improve your return on investment.

Automate Processes

We aim to minimise your manual tasks by automating processes such as the development of social media audiences, managing ads or syncing data with your external ATS (subject to API compatibility).

Frequently Asked Questions

Not sure if this is for you? Explore the frequently asked questions below or reach out to us for a discovery call.

If it's free-to-use, what's the catch?

Our goal is to maximise the opportunities available to candidates by removing the traditional barriers between employers and talent. Therefore, we provide basic employment marketing services for free.

This will be subsidised by any revenue made from our premium solutions, which are focussed on providing more advanced employment marketing strategies.

What guarantee can you offer if the paid-solutions don't work?

Our premium solutions become increasingly-effective over time as we grow your custom audiences, but if you’re not happy with the results after 30 days, we offer a 100% value-back guarantee*.

*Credit will be reimbursed to your account as spendable points that can be used as payment towards other services, such as featured job adverts or subscription packages.

Why should we join now if we aren't recruiting?

Best-practice employment marketing is about proactively building talent pools that can be leveraged when you need it. If an unexpected resignation or vacancy appears tomorrow, you will likely have to resort to the same reactive strategies as before.

Our system becomes increasingly-effective over time as we refine your talent pool and build more followers for you, which means it pays-off to start sooner rather than later.

Will this work for our niche requirements?

Yes. Since our solution leverages pre-existing social media networks, our solution is globally-effective, niche-independent, and will work anywhere that has high social media penetration (almost everywhere!).

However, some highly-targeted audiences may take more time to build and optimise, which is why we recommend starting the process sooner rather than later.

Will this solution integrate with our internal recruitment processes?

Yes! Our solution is designed to complement (not replace) legacy internal recruitment processes by enhancing the quality, volume and predictability of web-traffic to your job opportunities.

As a former geoscientist and recruiter, my goal is to help employers escape the trap of reactive, low-ROI recruitment solutions by making it easy to capture the value of proactive, high-ROI employment marketing strategies that continue to pay long-term dividends.
