Location: Darlington, NSW, with flexible working conditions where the work allows. Remote work will be considered

Reporting to: Test and Measurement Engineer

Position Overview

Join a supportive, collaborative team where curiosity and proactivity are valued.

In this role, you will spearhead a feasibility study demonstrating that Deteqt’s NV diamond sensors can measure weak oscillating magnetic fields at the sensitivity a new application requires. Working closely with a small team of engineers, you will turn theoretical predictions into a working proof‑of‑concept. You will also write and present the findings for an external audience, through explicit technical reports and regular updates.

About Deteqt

Deteqt is a fast‑growing, venture‑backed deep tech company developing NV diamond quantum sensing technology. Our devices deliver magnetic field intelligence: precise measurements from compact, scalable systems, turned into actionable insights for real‑world deployment. We are backed by Main Sequence Ventures, and are moving from prototype to product, working closely with early partners and customers across navigation, resources, and defence‑adjacent domains.

We’re a small, driven team who move quickly, take ownership and value clear communication. If you’re ambitious, curious and want to build something uncommon, you’ll fit right in.

Your Key Responsibilities

Feasibility study and requirements

Review and test the assumptions in an existing proposal for an AC magnetometry feasibility study, including key requirements such as signal strength, Larmor frequency, standoff distance and noise environment

Set the NV diamond performance requirements for AC magnetometry





Test bench and experiments

Work closely with the project leader to plan and carry out proof‑of‑concept experiments that demonstrate Deteqt’s NV diamond technology can meet those requirements

Set up and validate the test bench, including the AC field source, bias field, microwave delivery, optical excitation and readout

Run the proof‑of‑concept demonstration, measuring an oscillating magnetic field with our first‑generation NV diamond device. Compare the results with theory and published benchmarks, and document the results

Control electronics

Work closely with the team on the programming and testing of our new generation of control electronics, including preparing documentation, troubleshooting and implementation

Partner delivery and future design

Contribute to all milestones, deliverables and monthly updates with our partner

Outline requirements and specifications for future chip design iterations for implementations of portable MRI

Skills and Experience

Required

PhD (or equivalent experience) in physics, quantum engineering or a related field

Hands‑on experience with NV‑centre or other spin‑based quantum sensing, including ODMR, Ramsey, Hahn echo and dynamical decoupling

Strong grasp of the theory and performance implications of AC magnetometry,



spin coherence and sensitivity limits

Lab experience with microwave and RF systems, optics and laser control

Clear technical writing for reports and partner deliverables

High speed control and acquisition or pulse‑sequencer programming (e.g. development kits with FPGA control or similar)

Experience in a start‑up or in industry‑partnered research

What Success Looks Like in This Role

By the end of the six‑month contract, a successful Quantum Engineer will:

Prove the concept: Run a working demonstration of AC magnetometry using our first‑generation device and the test bench, with results compared against theory and published benchmarks

Deliver for the partner: Meet each milestone and monthly update on time, with clear written reports

Set up what comes next: Hand over a validated test bench, documented control electronics and draft specifications for future chip designs

Why Join Us

Hands‑on impact: Work directly on NV diamond devices with industry partners

Ground‑floor impact: Be part of a well‑funded, fast‑growing startup at a pivotal stage, shaping a globally significant technology

Values‑led culture: We prioritise curiosity, diversity of thought, and building with integrity

Mission with meaning: Help bring quantum sensing out of the lab and into real‑world domains that matter, from secure navigation to sustainable resource discovery

We welcome applications from individuals of all backgrounds and experiences. Don’t fit every single requirement but think you can step up? We want to hear from you!
