ABOUT THE ROLE

We are looking for a Senior Backend Engineer to architect and build the core systems of a next-generation AdTech platform that embeds products directly into visual experiences. You will design high-throughput, low-latency services for campaign delivery, targeting, attribution, and partner integrations using Python, Django, Kubernetes, and AWS. This is an early-stage initiative where senior engineers define the technical direction and system architecture from the ground up.

- Design APIs and services supporting campaign management, targeting, delivery, attribution, and reporting;

- Build and optimize high-throughput, low-latency systems processing large volumes of events and data;

- Own critical systems end-to-end, including design, implementation, deployment, monitoring, and ongoing improvements;

- Drive architectural decisions and establish patterns that support scalability, reliability, and developer productivity;

- Collaborate closely with product, data, and partner teams to translate business requirements into robust technical solutions;

- Provide technical leadership through design reviews, system discussions, and mentoring other engineers;

- Contribute to engineering best practices, documentation, and long-term platform vision;

- Participate in hiring and help grow a strong, high-performing team.

- Proven experience designing and scaling distributed systems focusing on performance, observability, and fault tolerance;

- Strong architectural instincts and the ability to make high-leverage technical decisions that impact multiple teams and systems;

- Demonstrated ability to influence and mentor senior engineers, guide teams through ambiguity, and elevate engineering practices across the board;

- Exceptional ownership mindset — you drive initiatives forward, raise the bar, and deliver lasting impact;

- Excellent communication and cross-functional collaboration skills;

- Availability to work till 1pm EST (till 8 pm Kyiv time);

- Comfortable operating in a fast-paced, high-autonomy, product-driven environment;

- Experience with e-commerce and catalog management is preferred;

- Familiarity with Python, Django, Kubernetes, PostgreSQL, and AWS is strongly preferred, but deep expertise in analogous systems and a willingness to learn are welcome;
