We are looking for a Senior Data Engineer to own the data platform of a fast-growing startup, from architecture all the way to production. The company helps investors and other teams find and research companies, so reliable, fresh and well-structured data is at the heart of the product. Today the platform processes data one job at a time in containers. You will lead its move to running many jobs at once, with event-driven data intake and orchestrated batch workflows. Your daily work will combine Python, Airflow, dbt, GCP and PostgreSQL with large-scale web scraping from many sources. You will also solve hard data problems, such as matching company and people records across sources and using LLMs to pull structured data out of text. This role suits someone who likes building from zero, enjoys owning a wide area, works well on their own and is comfortable in a fully remote team with no fixed working hours.

Details:

• Schedule: Full time
• Location: Remote – EU 
• Start: ASAP
• Duration: Long-term
• English: Fluent
• Type of collaboration: B2B Contract

About the project:
The client is a startup building a data platform that helps investors and other teams find and research companies. The platform collects data from many sources, cleans it, links related records and turns it into useful insights about companies. As the product grows, the current one-at-a-time processing needs to become a faster, event-driven system that handles many jobs at once. The Senior Data Engineer will lead this change and own the whole platform, from design to day-to-day running. The team is small, so engineers own a wide area and have a direct impact on the product. The company works fully remotely, and you don't need to overlap with anyone's working hours.

You have:

• Experience building a production data platform with many data sources from zero, including its architecture, deployment and day-to-day running
• Production experience with workflow orchestration tools (Airflow, Dagster, Prefect or Temporal)
• Hands-on experience with dbt and Google Cloud Platform (GCP)
• Strong Python skills, including asynchronous HTTP and concurrent processing
• Hands-on web scraping experience (Scrapy, Playwright, Selenium or Beautiful Soup)
• Strong PostgreSQL skills: data modeling, query optimization and reliable incremental loading
• Experience with event-driven architecture, including retries, failure recovery and dead-letter queues
• Comfort working fully remotely and on your own, with no fixed hours that overlap with the team
• Fluent English

Nice to have:

• Experience in startups or small engineering teams where you owned a wide area
• Entity resolution experience, especially matching and reconciling company and people records across sources
• Experience using LLMs to extract structured data or enrich data
• Familiarity with BigQuery and Dataform
• Background in company, investment or B2B data platforms

What to do:

• Own the data platform from start to finish, from architecture to production and day-to-day running
• Lead the move from one-at-a-time container processing to concurrent, event-driven data intake and orchestrated batch workflows
• Build and maintain data pipelines with Python, Airflow, dbt and GCP
• Build and scale web scraping that runs across many sources at once, handling rate limits and failures
• Design PostgreSQL data models, optimize queries, and set up reliable incremental loads, idempotent upserts and backfills of historical data
• Build solid failure recovery, retries and dead-letter handling for event-driven data intake
• Match and reconcile company and people records across different data sources
• Use LLMs to extract and enrich structured data where it helps

• Analyze schema design, data freshness, bottleneck risks, and overall data health to identify system vulnerabilities and inaccuracies.
• Design a clean, scalable, and future-proof target data architecture optimized for fast querying, BI reporting (Metabase), and AI/LLM ingestion (Text-to-SQL).
• Build a detailed step-by-step execution plan (Roadmap) specifying required engineering steps, timelines, and resource allocations needed to reach the desired state.
• Present audit findings and strategic recommendations directly to the US client leadership and product team.

We Offer:

• You'll collaborate with a global SRE organization using modern cloud-native technologies, Kubernetes, distributed systems, and large-scale SaaS workloads. You'll have the opportunity to lead impactful reliability initiatives, influence engineering best practices, and solve complex production challenges that directly improve the experience of both customers and engineering teams.

ʼAbout the role

You will join the team that owns the Data Lake: ingestion, storage, transformation and the platform other teams build their pipelines on. The domain is broad on purpose — one week you are tuning a Spark job, the next you are designing a CDC ingestion pattern, writing Terraform, or shaping how a business case becomes a data product.

Your future responsibilities:

• Design and build data pipelines end-to-end: ingestion from heterogeneous sources → cleaning, transformation, enrichment, normalisation/denormalisation → publication — with tests, monitoring and production ownership
• Make and defend the architectural calls in your slice: file/table format, partitioning, incremental vs. full reload, latency/cost trade-offs, failure semantics
• Translate business cases into requirements, architecture and code — and push back when the requirement is the problem
• Find both the fast path for an experiment and the stable path for production, and know which one you are on
• Continuously look for what in our processing should be simplified, automated or deleted

Your skills and experience:

Must have — breadth across the stack:

• Python as a working language for data engineering (not just scripting)
• SQL fluently: window functions, complex joins, reading and reasoning about execution plans
• Spark / PySpark: transformations, aggregations, window functions, UDFs — and enough understanding of shuffle, skew and partitioning to open a Spark UI and explain why a job is slow
• AWS data stack: S3, Glue, Athena, Lambda, Step Functions, IAM (equivalent depth in GCP/Azure is fine)
• Lakehouse fundamentals: Parquet, Iceberg (or Delta/Hudi) — partitioning, compaction, schema evolution, snapshots
• Orchestration: Airflow (or Dagster / Prefect / Step Functions)
• Docker, and comfort running workloads on Kubernetes
• Git + CI/CD, and exposure to IaC (Terraform / Terragrunt)
• Streaming and CDC concepts: Kafka, delivery semantics, late and out-of-order data, idempotent writes
• Debugging as a first-class skill: logs, metrics, a failed job at 9am, and a calm root-cause narrative afterwards
• English: you can read and write technical documentation
• Middle: 2+ years in a dedicated data engineering role. Solid across most of the above, genuinely strong in two or three areas.
• Senior: 5+ years designing, building and operating Data Lake / DWH solutions. Plus: you design things other engineers build on, you mentor, and you can carry a technical decision across team boundaries.

Must have — AI tooling:

• Hands-on experience with coding agents (Claude Code, Codex or similar) on production work: decomposing a task, giving it the right context, iterating to a result you would sign off on
• Critical review of generated code. You do not merge what you cannot explain line by line — correctness, cost and compliance stay yours regardless of who typed it
• Willingness to work outside your strongest area, using AI to get productive in an unfamiliar tool rather than routing the task elsewhere

Nice to have:

• A second language beyond Python (Scala, Java, Go, Rust)
• Owning IaC properly: Terraform / Terragrunt modules, not just editing existing ones
• dbt / SQLMesh, data contracts, lineage and catalog tooling
• Analytical databases: ClickHouse, Redshift, BigQuery, Snowflake
• Data modelling background (Kimball, Data Vault) and experience with regulated / audited data environments
• Experience building complex analytical systems end-to-end
