Position overview

This position reports to the Director of Engineering and joins a team of backend, data, and DevOps engineers building the services behind Adelaide’s measurement products, including the high-throughput APIs that ingest tracking data at scale and the partner-facing services that expose our segments and scoring to demand-side platforms. You’ll design, build, and maintain async Python services on FastAPI, working closely with Data Engineering and Data Science to move data reliably from client-side collection through to storage and downstream analytics, and you’ll get regular hands-on exposure to the data pipelines and cloud infrastructure that feed those services.

Day-to-day activities include writing and testing async Python code, designing and maintaining FastAPI services, working with AWS services such as Kinesis Firehose, S3, RDS/Postgres, Redshift, and MWAA Airflow, tuning batching and performance-sensitive request paths, and participating in code reviews.

We’re seeking a candidate with 3–5 years of professional software engineering experience, with most of it in Python.

This is a fully remote role within the United States, with opportunities to connect with colleagues at our New York office. You’ll need to be in NYC a few times per year.
