Who You Are · 5+ years of experience developing and shipping production-grade web applications. · Deep expertise in JavaScript and React, with experience architecting data-intensive, component-driven interfaces. · Strong experience with Python for backend development. · Skilled in designing and consuming RESTful APIs and working with PostgreSQL or similar databases. · Strong understanding of web technologies, browser performance, and the full software development lifecycle. · Experience working with AWS or other cloud platforms. · Excellent communication skills and a collaborative mindset suited to fast-paced, cross-functional teams. · Experience in the digital advertising ecosystem (SSP, DSP, ad servers, or OpenRTB/VAST standards) is highly desirable. Bonus Points · Experience with data visualization libraries (e.g., D3.js, Recharts). · Familiarity with containerization (Docker, Kubernetes) and microservices. · Background in building or scaling ad tech or analytics platforms. How You’ll Succeed · Thrive in a startup environment with evolving challenges and opportunities. · Contribute to solving difficult, high-scale technical problems with creativity and rigor. · Take ownership of your code and systems from design to deployment. · Proactively look for ways to improve performance, reliability, and user experience. · Collaborate constructively, bringing ideas and improvements to the table.
