Ad Age touted that "Known may be the ultimate example of a full-service agency," and honored us with top ten status on The Agency A-List for 2024 & 2025, and as Ad Age's Data & Insights Agency of the year for a record third year in a row. Without our incredible partnerships with our clients, spanning across the leading brands in finance, technology, entertainment, media, CPG, real estate, and many other categories, honors like this could not be possible, and also have helped us earn additional awards and recognitions over the years like : Emmys, Clios, Effies, Cannes Lions Awards, ProMax Agency of the Year, Fast Company's World Changing Ideas, Digiday's 2025 Best AI Platform and Digiday's Most Innovative Media Agency, to name a few.

We couldn't create this award-winning work without seeking out and hiring the best talent. What does it mean to be a Knowner? We are curious innovators, knowledge-hunters who are constantly challenging ourselves to do better and be better for our clients, for our team and for our world at large. Our offices around the U.S. are open and while most of our people work in a hybrid setting, we are a distributed workforce with a number of Knowners working remotely.

But enough about us, let's talk about you. As a Senior Software Engineer at Known, you can expect to work across various projects. You'll join small, highly focused teams where you'll have the opportunity to significantly influence the direction of our products, team practices, and the company's broader technical culture!

Because our work is often project-driven, we are constantly reevaluating and updating our tech stack, which means you'll always learn new skills and develop expertise in industry-leading technologies! On the backend, you'll work on distributed systems, API endpoints, event-driven microservices, asynchronous and parallel programming, pipelines, and reporting systems. You'll be responsible for designing these distributed systems and pipelines using a variety of architectural design patterns. You'll leverage industry-standard tools such as FastAPI, SQLAlchemy, PostgreSQL, Snowflake, Redis, Docker, Kubernetes, Vue, Streamlit, and more. Each project offers unique, exciting challenges!

You'll primarily use Python on the backend. Most of our infrastructure is cloud-based (AWS), and we use Docker and container orchestrators for deployment. We strive to implement practices like CI / CD, environment parity, and testing. Finally, we actively promote open-source projects internally; check out pytest-mock-resources, one of our in-house custom plugins!

What you'll do :

• Design and build full-stack web applications
• Create performant Web APIs with FastAPI
• Integrate with industry-standard datastores like PostgreSQL and Snowflake
• Design asynchronous and event-driven services
• Produce robust ETL pipelines with Argo Workflows
• Deploy these applications across multiple environments with Docker, Helm, and Kubernetes
• Work closely with data scientists and product managers on a wide variety of products and projects that span the marketing and advertising industries across both television and digital
• Play an active role in designing and building new, cutting-edge products
