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.
Must haves

Experience with AdTech;
Strong understanding of computer science fundamentals (algorithms, data structures, networking, databases);
Proven experience designing and scaling distributed systems focusing on performance, observability, and fault tolerance;
Experience with Python / Django, or other backend programming languages;

Strong architectural instincts and ability to make high-impact technical decisions;
Ability to mentor engineers and guide teams through ambiguity;
Strong ownership mindset with ability to drive initiatives and deliver impact;
Excellent communication and cross-functional collaboration skills;
Comfort working in a fast-paced, high-autonomy, product-driven environment;
