Platform Engineer (DevSecOps)

TL;DR

• Own and build Breaker's CI/CD platform from the ground up. GitLab, AWS, Docker, Infrastructure as Code

• Embed security into everything: static analysis, secrets management, secure-by-design pipelines

• 5–7 years experience in DevOps/DevSecOps, ideally in a startup or scale-up environment

• Strong expertise in GitLab CI/CD, AWS infrastructure, Docker, and Linux systems

• Australian citizenship required

• Join an exciting startup backed by globally recognised investors at the bleeding edge of physical AI

About Breaker

The way humans use robots is broken.

Modern problems demand more robots than we have operators. Every drone, ground vehicle, and maritime system requires dedicated training, manual control, and constant oversight. One operator per robot. One pilot per mission.

Breaker's AI agent breaks this constraint.

Our technology turns any robot into a truly autonomous, self-organizing teammate. Operators command and query teams of robots through natural language conversations over the push-to-talk radios they already carry, no laptops, no controllers, no additional gear.

Instead of manually flying search patterns across three different screens, you say, "survey this area and flag anything unusual." The robot team figures out how to divide the task, coordinate their movements, and report back what matters.

We're fundamentally changing the operator-to-robot ratio. Small teams become force multipliers.

Our software deploys directly onboard each robot, enabling real-time, intent-driven control even in contested environments with limited bandwidth. We're solving problems most AI companies never touch: sub-second inference on edge hardware with strict latency, power, and connectivity constraints.

We're backed by some of the best investors globally and growing our team across Austin, Texas, and Sydney, Australia. We're a small team of experienced engineers moving fast on technology that will define how humans and machines work together for decades to come.

About the Role

We're looking for a Platform Engineer to own and shape Breaker's CI/CD platform, cloud infrastructure, and security posture. This is a foundational role where you'll build the systems that every engineer at Breaker depends on to ship software, and you'll embed security into those systems from day one. Think GitOps methodology, Infrastructure as Code, and a shift-left mindset that puts quality and security tooling directly into developers' hands.

You'll be the go-to person for CI pipeline stability, build optimisation, package management, and the AWS infrastructure that underpins it all. You'll work closely with the engineering team daily, sitting alongside developers, unblocking them, and teaching best practices that compound across the organisation. The work is high-leverage: every improvement you make multiplies the output of the entire team.

This role reports to our engineering leadership and carries real autonomy over CI strategy and execution. You'll also play a key part in establishing secure, compliant infrastructure as Breaker scales across Australia and the United States.

Key Responsibilities

• Own the CI/CD platform end-to-end: pipeline design, stability, speed, and observability across GitLab

• Build and manage cloud infrastructure on AWS using Infrastructure as Code (IaC), including runners, networking (VPNs, VPCs), and compute

• Implement and maintain security controls within CI: static analysis, software composition analysis, secrets management, and dependency scanning

• Optimise build processes: Dockerfile restructuring, container size reduction, caching strategies, and package registry management

• Establish observability, reporting, and alerting across platform systems to surface issues before they become blockers

• Champion a shift-left approach. Push tooling like pre-commit hooks and linting into developer environments to catch issues early

• Adopt and enforce GitOps methodology: Git as the single source of truth for infrastructure and pipeline configuration

• Collaborate daily with software engineers, joining standups and acting as the first point of contact for CI and infrastructure issues

• Mentor and educate the engineering team on DevSecOps best practices, building a culture of shared ownership over platform quality

• Support the separation of configuration and security information to enable compliant multi-region infrastructure

About You

Required Skills and Experience

• 5–7+ years of experience in DevOps, DevSecOps, or Platform Engineering roles

• Deep expertise in GitLab CI/CD, like pipeline architecture, runners, configuration, and administration

• Strong AWS experience: IaC (Terraform/CloudFormation), networking, compute, and cost management

• Advanced Docker knowledge: multi-stage builds, image optimisation, registry management

• Security-first mindset with hands-on experience implementing static analysis, secrets management, and secure pipeline design

• Strong Linux systems administration and package management (comfortable with internals, e.g. Debian packaging)

• Experience with GitOps workflows and automation-first infrastructure management

• Excellent communication skills. You can explain infrastructure decisions to software engineers and collaborate effectively with passionate developers

• Australian citizenship (must be eligible for baseline security clearance)

Highly Valued Experience

• Background in startup or scale-up environments where you owned systems end-to-end

• Familiarity with robotics or embedded systems build tooling (e.g. ROS 2, cross-compilation)

• Exposure to MLOps workflows: managing data pipelines, GPU infrastructure, or model lifecycle tooling

• Experience with compliance frameworks (ITAR, CMMC, or similar) and multi-region secure infrastructure

• Mentoring ability: you've helped junior engineers grow and are comfortable guiding others

• Experience with hardware-in-the-loop test infrastructure or on-premise/hybrid workloads

Why Join Us?

You'll be an owner, not a renter. We're at the stage where foundational decisions are still being made and entire systems need to be built from scratch. Your work won't be maintaining someone else's legacy — you'll be creating what comes next. The problems you solve and the systems you build will define how Breaker scales.

You'll work with people who've done this before. Our team has shipped production robotics systems, scaled infrastructure, and solved the kind of hard integration problems that only come up when software meets the physical world. You won't be the only person in the room who's debugged a sensor fusion pipeline or optimized inference on a Jetson.

You'll solve problems that don't exist anywhere else. Most companies are building incremental improvements on established technology. We're defining new categories — which means the work is harder, more ambiguous, and infinitely more interesting.

You'll work hard, together. We're in the office every day, grinding on hard problems alongside great people. We've built a workspace where the best work happens — access to hardware, quick decisions, real collaboration. We're flexible when life requires it, but we're looking for people who want to show up, get stuck in, and build something significant with a team they respect.

We're going global. Backed by globally recognised investors, we're growing teams across Sydney, Australia and Austin, Texas. If you want exposure to international expansion and the opportunity to help build across regions, that path exists here.

You'll own what you build. Generous equity packages mean when Breaker wins, you win.
