Beneath the waves, beyond the reach of sight, an unseen battle is fought every day. 

Nations rely on intelligence to navigate threats, protect fleets, and ensure maritime security. 

But in the depths of the ocean, conventional surveillance fails. 

Sound is the only constant, and those who can decode its secrets hold the key to dominance below the surface.

This is where we come in.

We are a pioneering force in naval sonar technology, engineering advanced signal processing solutions that transform raw acoustic data into actionable intelligence. 

We provide cutting-edge systems that redefine the boundaries of underwater defense, leveraging machine learning and advanced acoustics to make the imperceptible, perceptible.

Your Mission

You’ll design and develop sophisticated algorithms for sonar systems, extracting vital intelligence from complex acoustic environments. 

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.

• Work where physics meets engineering - this is one of the most exciting technical challenges in quantum sensing today.

(Senior) Software Engineer: C++

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

📍Sydney

💼 Permanent

💰 $110k-$150k + super depending on experience

🔒 Australian citizenship = essential for NV1 clearance

“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

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.

*See what I did there ;)
