To thrive as a Full Stack Engineer, you need proficiency in both front-end and back-end programming languages (such as JavaScript, HTML/CSS, Python, or Java), along with a solid understanding of web application architecture and databases. Familiarity with frameworks like React, Angular, Node.js, and tools such as Git, Docker, and CI/CD systems, as well as relevant certifications, are often required.

How do Full Stack Engineers typically collaborate with UX/UI designers and backend specialists on a project?

Full Stack Engineers frequently act as a bridge between UX/UI designers and backend specialists, ensuring seamless integration of front-end interfaces with server-side logic. They participate in cross-functional meetings, translate design requirements into functional features, and address technical feasibility from both ends. This collaboration often involves code reviews, regular communication to clarify requirements, and agile workflows to ensure that user experience and system performance are both prioritized throughout the development process.

  • The client is seeking a senior full-stack engineer to own and drive backend services, APIs, and platform architecture across a fast-growing, IoT-powered retail media network scaling to tens of thousands of locations.
Job Summary
  • Build and maintain backend services and APIs using Python and Django, supporting real-time device fleet management across thousands of retail locations.
  • Design and architect scalable solutions for high-volume, public-facing systems, including multi-database routing, async processing pipelines, and near-real-time control of a large device fleet.
  • Translate loose product requirements into technical designs and task breakdowns, leveraging AI tooling (such as Claude Code) to move from PRD to implementation plan.
  • Develop integrations with third-party advertising and display platforms, contributing to ad-tech functionality around audio and display targeting.
  • Collaborate with the product team to define roadmap priorities, surface risks early, and communicate technical decisions clearly to business stakeholders.
  • Contribute frontend development in React and TypeScript as needed, supporting the full-stack nature of the role.
  • Operate autonomously in a fast-paced startup environment, generating your own tickets, owning work end to end, and supporting new customer onboarding and platform expansion.
Minimum Requirements:
  • 7 or more years of full-stack engineering experience, with a backend-leaning but genuinely full-stack profile (Python and Django on the backend, React on the frontend).
  • Demonstrated production experience with Django and Django REST Framework building large, public-facing APIs at scale.
  • Experience owning and delivering complete features or systems end to end, with a clear record of technical leadership and autonomous decision-making.
  • Familiarity with AI-assisted development workflows (such as Claude Code or similar), with the ability to direct, verify, and take accountability for AI-generated output.
  • Strong engineering judgment, with the ability to decompose ambiguous requirements, reason about failure modes, and right-size solutions without close oversight.
  • Experience working in startup or high-growth environments where engineers are expected to wear multiple hats and operate with limited process.
  • Multicultural or global team experience, particularly with distributed teams across time zones.
Preferred Qualifications:
  • Background in retail media, ad-tech, or digital out-of-home advertising platforms.
  • Experience with IoT, distributed fleet management, or systems managing large numbers of connected devices.
  • Familiarity with AWS cloud infrastructure and async or queue-based processing architectures.
  • Exposure to Elixir or other languages common in polyglot engineering environments.
