Your work will involve:

• Developing advanced signal processing techniques for sonar applications
• Applying machine learning to enhance detection and classification capabilities
• Working with real-world acoustic data to refine and optimize algorithms
• Collaborating with a multidisciplinary team of engineers and scientists to deliver state-of-the-art sonar solutions

What You Bring

You’re not just a software engineer. You’re a problem-solver, a scientist, and an innovator. You thrive in ambiguity, where the challenge isn’t just writing an algorithm - it’s uncovering patterns hidden in the noise. You have:

• A strong foundation in signal processing, acoustics, and machine learning
• Proficiency in Python, C++, CUDA or MATLAB for algorithm development
• Experience with real-time signal processing and embedded systems 

Why Join Us?

Here, your work matters. Your innovations will directly shape the future of naval defense. You’ll be part of a highly specialized team solving some of the most complex challenges in underwater surveillance, in a company that values technical excellence and creativity.

If you’re ready to make waves in an industry where precision means survival, let’s talk.

A submarine navigating the ocean depths.

A spacecraft far from Earth’s orbit.

A rescue team searching for survivors underground.

These are just a few places where GPS simply doesn't work. 

Without a reliable way to measure magnetic fields, these environments remain uncharted.

But what if you could change that?

A deep tech company is developing a breakthrough quantum sensing technology that could transform the way we navigate, detect anomalies, and explore the unknown. 

By combining quantum physics with advanced chip-scale manufacturing, they are building one of the world’s most precise magnetometers - and they need an Engineering Manager to make it a reality.

Your Role in This Mission

You will turn scientific innovation into a real-world product. 

At the intersection of optics, electronics, and embedded software, you will bring together all the elements needed to build a scalable, deployable quantum sensor.

Working alongside quantum physicists, embedded software engineers, and electronics designers, you will solve complex challenges in sensor arrays and signal processing, ensuring the system is both robust and scalable. 

Your work will lay the foundation for next-generation sensors, shaping advancements that will redefine navigation and detection for years to come.

Who You Are

• Over the years, you’ve built and refined complex hardware/software systems, turning concepts into working prototypes.

• You have a background in sensing technologies, navigation, or imaging and thrive on tackling multidisciplinary challenges.

• You’re hands-on with hardware design, ideally in an FPGA environment - you don’t just design; you build, test, and refine.

Why Now?

This isn’t about incremental improvements. It’s about building a revolutionary sensing technology from the ground up.

• Join a backed, fast-moving team - funding is secured, and strategic partnerships are in place.

• Shape a deep tech breakthrough - your work will define the engineering strategy for a first-of-its-kind quantum sensor.

(Senior) Software Engineer: C++

Solve big problems with high stakes in a fluid, squad-style engineering team

📍Sydney

💼 Permanent

💰 $110k-$150k depending on seniority & experience

“Mission critical”.

Over-used?

It's definitely a phrase we hear a lot at The Onset.

Unsurprising, given our clients that design engineering solutions to keep aircraft in the sky, ships afloat, and underwater robots in line of sight.

Just so happens that this company is one of those clients…

The problem

Growth = project pipeline uptick = stretched team.

The brief

Hire C++ engineers that can take ambiguous requirements, in mission critical* situations, design watertight* solutions and ship* them quickly.

The setup

Plug into a seasoned, diverse group of engineers and find your place in a project squad aligned with your skills and ambitions.

The hook

Solve problems today that didn't exist yesterday. Implement them tomorrow.

The target

"An engineer, not a developer" - this is full lifecycle engineering. No, really. Only the most ambitious and self-sufficient truly succeed here.

The foundation

*Australian citizenship = essential for NV1 clearance*

Multithreaded C++ on Windows (some helps too). GUI design & implementation. SQL. Broad tooling & scripting from VS to Qt to Python.

Bonus points for

Linux. *Modern* C++ (>20).

Look, you made it to the end! If this ad has spoken to you, why stop here? Apply to hear more.

If you’ve read this far, you’re probably thinking this is a fit.

Apply and let’s find out.

You might be part of a large cyber team, where your role is an inch wide but a mile deep, and you're looking to broaden your impact.

Or maybe you're a one-person band, running the entire security function solo, and you're ready to work with a slightly bigger team.

Perhaps you don’t have enough support in your current role, and you're tired of banging your head against the wall.

What if you could be closer to the Executive Leadership Team—where security isn’t just an afterthought, but a function that’s valued and celebrated?

A professional services company is looking for a experienced Cyber GRC & Assurance Manager to further elevate its already mature and highly regarded security assurance function. Their security program is established and respected across the company, supported by the type of executive buy-in that’s often hard to find. This role is focused on refining and enhancing an already successful initiative; it's not about rebuilding. You’ll oversee the GRC and Assurance portfolio, ensuring the program remains audit-ready, continuously improving, and aligned with client security needs. Reporting directly to the CISO, you’ll also serve as 2IC when needed, playing a central role in security governance, risk management, and compliance.

While they're not a regulated entity, it works with clients who are, making security a crucial business enabler and differentiator. Improving the customer experience, both inside and outside the organization, is a core focus, and the security program plays a vital role in maintaining client trust and satisfaction.

In this role, you’ll work across a range of compliance frameworks, including ISO 27001, CPS 234, NIST, ASD Essential 8, and SOC 2 Type 2. This role offers variety, touching multiple areas such as leading client security audits, responding to inquiries, and reviewing Cyber Security contracts to ensure alignment with client expectations. Additionally, you’ll oversee the Cyber Trust Centre Portal, ensuring a proactive and robust client assurance program.

Supply chain security will be another key area of focus, where you’ll enhance vendor risk assessments and third-party security, ensuring consistency and best practices across the firm’s network of partners and vendors.

You’ll also provide high-level reporting on Cyber Security performance, ensuring senior leadership is kept informed—this includes tracking and reporting on key risk indicators and cyber risk registers.

If that's not enough, you’ll also lead Cyber Security awareness and training programs, collaborating with internal teams to ensure employees understand and follow security best practices.

You’ll be well-supported in this role, managing one direct report (a Security Analyst) and collaborating with internal teams and external consultants to support governance, risk, and compliance initiatives. You won't be alone.

We are looking for someone with a technical background, who has managed a team and brings experience in Cyber GRC, with hands-on expertise in managing assurance programs.
