Senior Software Engineer - In Store Systems

About QSIC

QSIC is reinventing in-store audio. We use Audio, Intelligence (AI) and Creativity to redefine the value of in-store audio and drive growth for retailers and brands. Our story began in Australia over a decade ago with a love for music and a simple purpose: to create value that others can’t see. We sought to bring that to life through exceptional audio experiences, so we built the leading intelligent in-store audio platform for retailers and brands. At QSIC, in-store audio has never been just “background noise.” Audio has the power to change the atmosphere, spark emotion and shift the atmosphere. When it’s seamlessly woven into an in-store experience, it doesn’t just play – it connects. It engages shoppers without distracting them, influences decisions where it matters most, and elevates the entire shopping journey. Today, QSIC technology powers thousands of stores across three continents, reaching over 100 million shoppers each month.

• QSIC’s Ad Platform removes the friction of ad production, and instantly creates targeted, brand-aligned messaging with AI. Advertisers can use our Planning solution to eliminate guesswork by having their messages dynamically placed in the market - at the right time, for maximum impact. Every ad play is recorded and verified, providing unprecedented transparency.
• QSIC’s In-Store Audio solutions deliver intelligent, scalable and personalised playlists to match brand identities, and automated volume control to adjust for every moment!
• QSIC Intelligence provides enhanced targeting, and predicts the right message for every moment using our data-driven insights. The QSIC Intelligence solution includes performance analytics and self-service reporting.

Our motivation is to create value that others don’t see. Our promise is to use audio, intelligence and relentless dedication to transform spaces and deliver results. We have team members based in Australia, the United States and Mexico, and received Series B funding in January 2025. We’re just getting started!

About The Role

Role

QSIC manages a fleet of tens of thousands of devices distributed across APAC, the US, and globally. As part of the In Store Systems team, you will use your technical expertise to build tools and processes that help us deliver a high quality in store experience using our customer’s enterprise networks. A typical week in this role may include:

• Building the Golang components running on our RaspberryPi based media players installed in customer stores, communicating with smart speakers on the local network. Over the first 6 months, you’ll likely help rewrite our existing components from Python to Golang using MQTT for communications.
• Building and scaling the Golang API that serves those devices, integrating with our Python core API. You will be helping to refactor logic into this API to improve robustness, and starting the process to push that down to the devices as it becomes feasible.
• Working with our Platform and Ops teams to ensure a careful rollout of components across our fleet and ensure a great in store experience as we iterate.
• Collaborating with our Platform and Engineering teams to improve the build and deployment process, and ensure our observability pipelines correctly monitor the status of our fleet.

As someone with a background in production applications or reliability engineering, you’ll bring a passion for delivering stable, robust software to our devices, and a drive to continually improve the robustness of our systems. You’ll be eager to collaborate with your peers through the development process, participating in our code review and design review practices. You’ll be someone who is seeking to grow and learn in a fast-paced technology company, and keen to play a part in supporting QSIC’s continued growth and scale, globally.

What You’ll Do

• Build and manage on-device components, moving from legacy Python to Golang to improve their robustness, streamline development, and help us push more logic to the edge.
• Build and manage a Golang API to provide reliability improvements to how we manage our devices at scale.
• Improve the CI/CD pipeline of our components and infrastructure, deploying our API via ECS and device components via AWS’s IoT services.
• Manage and scale the infrastructure that underpins the device fleet, and help it keep pace with a rapid global expansion in active devices.
• Work closely with our platform team to ensure we have tools and processes used daily by our support and ops teams.
• Work closely with the EM and CTO to iterate on the technical vision for how we operate devices on customer networks at scale.
• Participate in our in-hours support, incident management and after-hours on call processes as a technical expert.

About You

Experience

You Must Have

• Experience as a software engineer, having worked on production applications both as a solo contributor and as part of a team. You understand how to get things shipped, and you know the tradeoffs between when to go solo and when team collaboration and alignment is more important.
• An interest in reliability engineering - making systems more robust, scaling, and ensuring a great experience for our customers in store.
• Comfort working across a range of technology up and down the stack - you can implement an API endpoint, deploy it to production and migrate workload across to it, and then debug issues in the underlying docker image or Linux services.
• Used Golang in production environments, be it in an application development or supporting roles such as DevOps tooling.
• Technical fluency in:
• Golang and/or Python.Linux fundamentals, including managing services and using key command line tools.
• TCP/IP Networking fundamentals, HTTP, and common network protocols and patterns.Command line diagnostics and low level system and networking tools such as tcpdump.
• Basic shell scripting with bash or similar.Managing CI/CD pipelines, ideally with Buildkite and/or Github Actions.
• Familiarity with AWS, in particular services such as S3, Route53, ECS, and Cloudfront.Familiarity with tools like Terraform to manage infrastructure.
• Experience with observability and monitoring tools - we use Datadog, but you may be familiar with another similar tool.
• Comfort collaborating with cross-functional teams inside QSIC, and working with technical and non-technical stakeholders to translate and build alignment.
• A desire to own projects end to end, while being supported by a small, high performing team.
• Experience working effectively in a remote-first organisation that crosses timezones and cultures.
• Full, unrestricted work rights for Australia (unfortunately we are unable to offer immigration assistance for this position).

Bonus Points If You

• Have experience with:
• Physical hardware deployed on-prem or within data centres.
• High-throughput or complex data applications such as video or voice.
• Hardware projects, such as electronics or embedded systems.

Our Values

• Honesty First: Keep it real, mate. We celebrate frank communication that is direct, open, respectful, and fair. We choose honesty over getting it “perfect” every time.
• Invent Solutions : Roll up your sleeves. We see a problem and don’t dwell on it but rather - we understand it, we own it, we solve it. We don’t see a wall, but a hurdle ready for us to take.
• Learn Everyday: Soak it up. We have a genuine insatiable curiosity and never take ourselves too seriously.
• One Team : We are all in this together. We value the diversity of our people—their nuances and differences. When we come together as a team, that’s what makes us truly great.
