Job description

Ripjar specialises in the development of software and data products that help governments and organisations combat serious financial crime. Our technology is used to identify criminal activity such as money laundering and terrorist financing, enabling organisations to enforce sanctions at scale to help combat rogue entities and state actors.

Data infuses everything Ripjar does. We work with a wide variety of datasets of all scales, including an ever-growing archive of billions of news articles covering most languages going back over 30 years, sanctions and watchlist data provided by governments, and vast organisation and ownership datasets.

About the Role

We see a Data Engineer as a software engineer who specialises in distributed data systems. You’ll join the Data Engineering team, whose prime responsibility is the development and operation of the Data Collection Hub, a platform that ingests data from many sources, processes/enriches it, and distributes it to multiple downstream systems.

We’re looking for someone with 2+ years of industry experience building and operating production software who enjoys working across data pipelines, distributed systems, and operational reliability.

What you’ll do

• Engineer distributed ingestion services that reliably pull data from diverse sources, handle messy real-world edge cases, and deliver clean, well-structured outputs to multiple downstream products.
• Build high-throughput processing components (batch and/or near-real-time) with a focus on performance, scalability, and predictable cost, using strong profiling and measurement practices.
• Design and evolve data contracts (schemas, validation rules, versioning, backward compatibility) so downstream teams can build with confidence.
• Own production quality: write maintainable code, strong unit/integration tests, and add the observability you need (metrics/logs/tracing) to diagnose issues quickly.
• Improve platform reliability by hardening pipelines against partial failures, retries, rate limits, data drift, and infrastructure issues—then codify those learnings into better tooling and guardrails.
• Contribute to CI/CD and developer experience: faster builds, better test signal, safer releases, and automated operational checks.
• Participate in design reviews, code reviews, incident retrospectives, and iterative delivery—making pragmatic trade-offs and documenting them clearly.
• Languages: Predominantly Python and Node.js
• Distributed/data platforms: HDFS, HBase, Spark, plus increasing use of Kubernetes and cloud services
• Storage/search: MongoDB, OpenSearch
• Tooling: GitHub, GitHub Actions, Rundeck, Jira, Confluence

Requirements

• 2+ years building and operating production software systems
• Fluency in at least one programming language (Python/Node.js a plus)
• Experience debugging moderately complex systems and improving reliability/performance

Nice to have:

• Hadoop ecosystem exposure (HDFS/HBase)
• Workflow orchestration (Airflow/Dagster/NiFi)
• Kubernetes and infrastructure-as-code
• Degree in Computer Science or numerical degree
• Competitive salary DOE
• 25 days annual leave + your birthday off, in addition to bank holidays, rising to 30 days after 5 years of service.
• Private Family Healthcare.
• Employee Assistance Programme.
• Company contributions to your pension.
• Pension salary sacrifice.
• Enhanced maternity/paternity pay.
• The latest tech including a top of the range MacBook Pro.
