Senior Data Engineer

Help build and take real ownership of the data platform behind proof, insights and optimisation in open-web video advertising,

processing billions of video streams and hundreds of billions of events.

The open web has massive untapped advertising potential, but video has historically underperformed here. SeenThis is changing

that. As a video advertising partner, we prove the open web delivers exceptional results, capturing more attention with

cost-effective video that keeps publishers profitable and the internet independent. Since 2017, we've served billions of streams

for 5,000+ brands across 50+ countries.

We believe brands deserve reach wherever audiences are, publishers deserve sustainable revenue, and the internet deserves to stay

open.

Our team of 130+ employees works globally from offices in Stockholm, Oslo, London, Paris, Singapore, Hong Kong, New York and

Sydney. We're expanding across all teams and looking for people who want to make a real impact in a fast-moving, collaborative

environment.

You'll join our R&D organisation, where Product, Engineering, Design, Data and Infrastructure work together across three product

streams: Core Tech, our streaming, delivery and measurement technology; Studio, our production system for advertising; and

Creative Manager, the workflow and orchestration layer around campaign execution.

Data works across all three and supports teams across SeenThis, turning product, operational, commercial and financial data into

governed models, shared definitions, reporting and insight.

The data team today consists of a lead data engineer, who built the platform and leads its technical direction, and a data analyst

working closely with teams across reporting, insight and the business.

You'll be the second data engineer, with substantial hands-on responsibility for running and evolving the platform and its

governed models, and a real say in where we go next.

The platform was rebuilt over the past year and now runs in production across high-volume streaming and event data, alongside

product, campaign, CRM and finance data.

You'll thrive here if you enjoy shaping the solutions and how to build them rather than just executing against a fixed spec,

partner naturally with business stakeholders to get at the real problem before reaching for a technical solution, and take

initiative to move things forward.

Our stack includes Python and SQL, Airflow 3 on GKE, GCS and S3, BigQuery, ClickHouse, and Terraform across GCP and AWS. We use AI

tools in engineering where they add value, backed by the fundamentals to judge their output.

• Make it reliable without constant attention through data-quality checks, monitoring and alerting, idempotent pipelines,

backfills and repair tooling.

• Work with data of very different shapes and scales, from high-volume events to third-party APIs, operational databases and

files.

• Build the trusted data products behind campaign reporting, commercial and financial reporting, billing and reconciliation,

product insight and operational decision-making.

• Work directly with teams across SeenThis to identify what data can do for them and shape ambiguous problems into valuable use

cases. You will not wait for someone to hand you a finished spec.

As we review applications and interview continuously, please apply as soon as possible. Due to the high volume of applications, we

are unable to provide personalised feedback prior to the interview stage. Thank you for understanding!
