Field Service Role | Sydney-based with frequent international travel

Advent Atum is seeking a senior software engineer to take ownership of our radar, command-and-control, and external sensor integrations.

This is not a conventional web development role, and it is not suitable for someone who relies on AI tools to write code they can't independently understand, test, debug, or defend.

You will be responsible for implementing, hardening, deploying, and supporting integrations between our HORAS software, radar systems, battle-management systems, sensors, effectors, and customer command networks.

A major part of the role involves travelling to customer sites, ranges, integration facilities, and operational environments in Australia and overseas. You must be comfortable working directly with customers, operators, partner engineering teams, incomplete documentation, unfamiliar hardware, and systems that need to function reliably outside the laboratory.

Responsibilities

Design and implement radar, sensor, C2, and battle-management system integrations

Develop and maintain integration services primarily using Rust

Implement secure and resilient distributed communications using Zenoh

Integrate third-party systems over UDP, TCP/IP, serial, CAN, Ethernet, multicast, and vendor-specific protocols

Interpret and implement interface-control documents, message schemas, and communications standards

Work with standards and protocols such as ASTERIX, SAPIENT, Cursor-on-Target, ADS-B, DIS, and NATO or defence messaging formats where applicable

Develop adapters, gateways, data translators, and middleware between otherwise incompatible systems

Diagnose packet-level, timing, synchronisation, networking, and data-integrity issues

Harden systems against packet loss, latency, malformed data, dropped connections, unreliable networks, and unexpected operator behaviour

Conduct factory acceptance testing, field integration, live trials, and customer demonstrations

Deploy software onto Linux-based edge computers and rugged embedded systems

Produce clear interface documentation, test procedures, logs, and technical reports

Support systems at customer locations in Australia, Europe,



the United States, Ukraine, and other international sites

Work closely with software, embedded, electronics, radar, mechanical, and fire-control engineers

At least five years of qualified software engineering experience

Strong production experience with Rust, C++, or another systems programming language

Demonstrated ability to design, implement, test, and debug networked software without relying on generated code

Strong understanding of:

TCP/IP and UDP

Multicast and broadcast networking

Binary protocols and serialisation

Asynchronous and concurrent software

Distributed systems

Linux networking and system administration

Experience reading packet captures and debugging protocols using tools such as Wireshark or tcpdump

Experience implementing systems from incomplete specifications, ICDs, or vendor documentation

Ability to work directly with hardware and distinguish software faults from networking, electrical, timing, or mechanical faults

Strong troubleshooting skills and the ability to reason from first principles

Willingness and ability to travel internationally on short notice

Ability to work independently in field environments without constant supervision

Highly regarded

Experience with Zenoh, ROS 2, DDS, MQTT, ZeroMQ, or comparable middleware

Command-and-control, battle-management, air-defence, counter-UAS, or defence systems experience

Experience with ASTERIX, SAPIENT, Cursor-on-Target, ADS-B, DIS, Link 16 gateways, or similar standards

Experience integrating EO/IR sensors, radars, navigation systems, effectors, or remote weapon systems

Experience with embedded Linux, NVIDIA Jetson, ARM platforms, Docker, systemd, and cross-compilation

Experience implementing TLS, certificates, authentication, key management,



and secure communications

Experience operating at test ranges or customer sites

Experience conducting formal integration testing and acceptance activities

Defence, aerospace, robotics, autonomous systems, industrial automation, or telecommunications background

Who will succeed in this role

You are the person other engineers call when two systems are meant to communicate but do not.

You can read an ICD, inspect a packet capture, identify whether the sender or receiver is wrong, implement the fix, test it against real hardware, and explain the result clearly to the customer.

You understand that software which works on a developer's laptop is not necessarily operational software.

You are comfortable being accountable for the result. You do not hide behind frameworks, generated code, vague architecture diagrams.

Who should not apply

This role will not suit:

- Developers whose experience is primarily websites, dashboards, or CRUD applications
- Engineers who cannot work without Copilot, ChatGPT, or generated code
- Candidates who cannot explain the code they submit
- Candidates who avoid hardware, networking, customer sites, or field testing
- Engineers who expect complete requirements before beginning useful work
- People who are unwilling to travel or work occasionally outside normal office hours during deployments and trials

Location and travel

The role is based at Advent Atum’s Sydney facility.

Frequent interstate and international travel is required. Deployments may range from several days to several weeks depending on the customer and integration activity.

Travel may include operationally demanding environments. Appropriate risk controls, insurance, travel support, and deployment planning will be provided.

Application requirements

Applications must include:

A CV outlining relevant systems, networking, radar, C2, robotics, defence, or embedded experience

Examples of integrations or distributed systems you personally implemented

A brief explanation of the most difficult protocol or communications fault you have worked on.
