Role
Who you are
- 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
- 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
- Strong fundamentals: data structures, testing, version control, Linux basics
Desirable
- Spark/PySpark experience
- Hadoop ecosystem exposure (HDFS/HBase)
- Workflow orchestration (Airflow/Dagster/NiFi)
- Search/indexing (OpenSearch, MongoDB)
- Kubernetes and infrastructure-as-code
- Degree in Computer Science or numerical degree
What the job involves
- 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
- 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
- Technology Stack:
- Languages: Predominantly Python and Node.js
- Distributed/data platforms: HDFS, HBase, Spark, plus increasing use of Kubernetes and cloud services
- Storage/search: MongoDB, OpenSearch
- Orchestration: Airflow, Dagster, NiFi
- Tooling: GitHub, GitHub Actions, Rundeck, Jira, Confluence
- Deployment/config: Ansible (physical), Terraform / Argo CD / Helm (Kubernetes)
- Development environment: MacBook (typical)
Our take
Ripjar provides a data intelligence platform, Labyrinth, that uses Artificial Intelligence to protect organisations against financial crime threats like money laundering, fraud, and funding terrorism. Labyrinth enables human analysts to make better-informed decisions with speed and accuracy, saving their clients’ costs and time.
Previous investments signify confidence in Ripjar's data intelligence technology and its ability to protect companies and governments from criminal activities that jeopardise their assets and prosperity. And it's no surprise, as Ripjar claims Labyrinth is the most sophisticated and advanced cyber-security solution on the market.
As economic uncertainty rises globally, so does the incidence of financial crime, particularly with the increasing shift to online transactions. Both tech companies and the UK government are turning to Ripjar to address these challenges. With a global client base exceeding 20,0000 and recent innovations, the company is well set to see further growth.
