Senior Software Engineer - Ad Tech - US Remote

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

QSIC is looking for a Senior Engineer to work with our full-stack Ad-Tech team - developing our React-based advertising management tools, and the Python / Django API that powers them. This is a fulltime, remote role required to be located in the Pacific or Mountain timezone, or to work the hours of one of these timezones, to ensure overlap with both our Dallas and Australia teams. This role may be performed from Canada, as a temporary worker engaged via one of QSIC's staffing partners.

QSIC manages a fleet of tens of thousands of devices distributed globally, and we build both internal and self-service tools to manage that fleet for our enterprise customers. As part of our Ad-Tech team, you will use your technical expertise to iteratively deliver new capabilities and features to our customers - both our back-office and self-serve tools, as well as back-end optimisation and scheduling systems powered by that data.

A typical week in this role may include

Working within a full-stack team to scope and design a new set of functionality for our internal or external users, focussed on our ad-tech and retail media products. This work may include new management or workflow interfaces, dynamic reports and visualisations, and chat and AI powered interfaces.

Contributing to Product Requirement Documents scoping upcoming work, and RFC documents designing the technical challenges to be solved by the team. Recent projects have included a major rewrite of our Permissions and Authentication system, tools to visualise fleet capacity, and major improvements to our ad scheduler.

Working with our technical teams to iteratively improve our developer experience (DX) and tooling, including build and deployment processes, local environment tooling, and observability tools.

As someone with a background working on production-grade web applications, you'll bring a passion for delivering stable, robust software, and a drive to continually improve the experience for our end users. 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

Design, build and manage our internal and customer-facing React application, and the Python / Django API that underpins it. As a full stack developer, you will be comfortable bridging the gap between back and front end, even if you find yourself spending more time in one.

Improve the CI / CD pipeline and infrastructure, deploying our API via ECS.

Manage and scale our infrastructure to ensure it keeps pace with a rapid expansion in active devices, new customers, and new markets.

Work closely with your team's Engineering Manager (based in the US), Product Manager and Design team to iterate on the technical vision for our product.

Collaborate with our Data & AI team on projects related to our scheduling and optimisation system, measurement reporting, and innovative AI and ML tools.

Collaborate with our engineering teams and leaders based in Australia to continually improve the DX, observability and maintainability of the system.

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.

Built and maintained products in the adtech space.

Comfort working across a range of technology up and down the stack - you can help design the interaction for a React component, implement the API endpoint for it, deploy it to production, and monitor for feature use and production issues.

Working technical fluency in

Python and Django, or a similar back-end language such as Ruby or Typescript and an eagerness to contribute to the Python codebase.

React or similar front end frameworks.

RESTful API design and implementation. RDBMS fundamentals, particularly MySQL or Postgresql.

Comfort working in cross-functional, agile teams in a fast paced, collaborative environment. We skew towards light-weight Kanban-style processes where we can, with close collaboration between Product, Engineering, Design and non-technical stakeholders.

Experience using and managing CI / CD pipelines, ideally with Buildkite and / or Github Actions.

Experience using and managing AWS, in particular services such as S3 and ECS.

Experience using observability and monitoring tools - we use Datadog, but you may be familiar with another similar tool.

Strong, demonstrated ability to work effectively in a remote-first organisation that crosses timezones and cultures.

Right to work in the United States (unfortunately QSIC is unable to provide visa sponsorship for this position)

Bonus points if you have experience with

Infrastructure-as-Code tools like Terraform.

Advanced mathematics concepts such as statistics, vector calculus or linear algebra.

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.
