Role Overview

We are looking for a Senior Software Engineer (IC4) to take ownership of the high-scale backend services powering our advertising ecosystem. You will be responsible for building and optimizing the systems that handle millions of events every day and interface with our third parties. This role requires a deep specialist in Python/Django who is equally comfortable diving into Big Data pipelines and ensuring our designs are performant, consistent, and scalable.

Core Responsibilities

• Technical Ownership: Lead the development and maintenance of mission-critical backend services, ensuring high throughput and low latency of APIs.
• Backend Optimization: Write clean, efficient, and highly performant code in Python and Django. You will be the go‑to person for solving complex concurrency issues and optimizing service performance.
• Big Data Execution: Design and optimize data workflows. You will write and tune complex queries in Hive, Flink, or Trino to ensure our data processing is both fast and cost-effective.
• Cross-Stack Collaboration: Collaborate with Front‑End engineers to ensure client‑facing features are designed for maximum data fidelity and backend compatibility.
• AI Implementation: Work closely with leadership to implement AI/ML‑driven features, such as automated anomaly detection or predictive data cleaning, within our production pipelines.
• Mentorship: Provide thoughtful code reviews and technical guidance to mid‑level engineers, fostering a culture of technical excellence.

Technical Requirements

• Experience: 6–9 years of professional backend experience, with a significant portion spent in high‑scale environments (Ad‑Tech, Data‑heavy SaaS, or FinTech).
• Python/Django Specialist: Mastery of Python and the Django ecosystem, including experience with asynchronous task processing (Celery/Redis) and database optimization.
• Big Data Proficiency: Hands‑on experience with distributed data processing frameworks like Flink, Spark, or Hive. You know how to handle 'data drift' and optimize large‑scale joins.
• SQL & Query Performance: Advanced SQL skills. You should be able to optimize complex analytical queries and understand database internals (indexing, partitioning).
• FE Awareness (Good to Have): Familiarity with Front‑End system design (e.g., React, JS event‑loops) and how client‑side tracking impacts backend data integrity.
• AI/ML Exposure: Practical experience or strong interest in deploying AI models into production environments to solve operational challenges.

Benefits

Full‑time employees can take advantage of health coverage, paid parental leave, generous paid time‑off and holidays, quarterly self‑care days off, and stock options. We’ll make sure you have the equipment and support you need to work and connect with your teams, at home or in one of our offices.
