Top 5 Tech Roles You Need to Hire for in 2025

As Australia's tech sector accelerates, businesses across Sydney and Melbourne are rethinking their hiring strategies. Demand is surging for professionals who can lead innovation, build scalable systems, secure digital assets, and harness data at scale.


Whether you're building a product or growing a platform, here are five essential tech roles that are shaping the future of work in 2025 — and why they're critical to stay competitive.


1. Technology & Digital Leaders

Tech transformation starts at the top. Roles like Chief Technology Officer, Chief Digital Officer, and Heads of Engineering, Cybersecurity, or Data are responsible for aligning technology strategy with business outcomes. These leaders drive organisational change, scale digital delivery, and make investment decisions that impact long-term growth.


2. Software Engineers & Technical Architects

The need for skilled engineers continues to grow, especially in mobile (iOS, Android, Flutter), front-end and full-stack (React, Angular, Node), and back-end (Java, Python, C#) development. Meanwhile, solution architects and technical architects are essential to ensuring platforms are scalable, secure, and user-centric.


3. Data, AI & Business Intelligence Specialists

Data is no longer optional—it’s the foundation of strategic decision-making. In 2025, roles in data engineering, machine learning, data science, and BI analysis will be in especially high demand. Organisations are also investing more in data governance and AI ethics, requiring professionals who can balance innovation with responsible data use.


4. Cybersecurity Experts

From financial services to healthtech, security is now a business-critical function. Roles like Security Architects, Penetration Testers, SOC Analysts, and GRC (Governance, Risk & Compliance) professionals are key to defending against threats and maintaining trust. Expect growing demand for specialists in DevSecOps and application security as well.


5. Cloud, DevOps & Infrastructure Engineers

Modern tech environments require seamless delivery pipelines, resilient infrastructure, and scalable cloud platforms. Companies are prioritising hires in DevOps, Site Reliability Engineering (SRE), Cloud Architecture (AWS, Azure, GCP), and Platform Engineering. Supporting roles like System Administrators, Network Engineers, and Service Delivery Managers also remain vital.


These five role categories are more than just open positions—they’re pillars of modern tech strategy and growth for organisations across Sydney and Melbourne.


Whether you're building an executive tech team, scaling platform development, or securing critical infrastructure, SustainRecruit has the local market knowledge and recruitment expertise to deliver top-tier talent with precision and integrity.

What Top Marketers Look for in a Role Today

September 17, 2025
In 2025, the marketing job market is overflowing with opportunities. But here’s the twist: the most in-demand marketers are the ones being selective. They’re not chasing just a paycheck. They want careers with meaning, growth, and influence. At SustainRecruit, we speak with top marketers every day. Here’s what they consistently tell us they’re looking for and what sets great employers apart. 1. Flexibility That’s Actually Flexible Hybrid has become standard. What matters now is how it’s delivered—autonomy, trust, and outcome-focused work. Marketers want to be judged on results, not time at a desk. Tip: Go beyond saying “hybrid.” Show how your teams balance collaboration and independence. 2. Clear Career Progression Ambitious marketers want to see the ladder before they climb it. That means defined promotion paths, mentorship, and a culture that invests in continuous learning. Without this, top candidates will move on quickly. 3. A Voice in Strategy Marketers no longer want to just deliver campaigns—they want to shape them. Employers that invite them into the strategy room early demonstrate respect for their expertise and attract stronger talent. 4. Purpose That’s Authentic Candidates see through empty brand promises. They’re drawn to organisations with clear values, transparent leadership, and a purpose that feels real—not a recruitment slogan. 5. Respect for Work-Life Balance Burnout is rife in marketing, and candidates are prioritising roles that protect their time. A culture that genuinely supports balance, like actually logging off at 6pm, can be more compelling than any wellness perk. Top marketers know their worth. They’re looking for substance: flexibility, progression, influence, authenticity, and balance. At SustainRecruit, we help employers meet these expectations and position themselves as the destination of choice for the very best talent.
