We build advanced, cloud‑native technology that detects, prevents, and responds to emerging threats across the UK and Europe.
As a Senior Data Engineer, you’ll join a highly skilled, cybersecurity‑focused development team delivering real‑time data pipelines, decisioning systems, and tooling that protect hundreds of thousands of clients. If you want to apply your engineering expertise to problems with genuine societal and financial impact, this is the place to do it.
What you’ll doData Engineering & Real‑Time SystemsDesign and implement real‑time data pipelines that power fraud detection and operational decision making.
Build robust ELT workflows from source ingestion through to data presentation for internal stakeholders.
Develop event‑driven solutions using technologies such as Apache Kafka and Apache Flink.
Write high‑quality, testable, maintainable code in Python or Java, with strong SQL capability.
Contribute to solution design, code reviews, automated testing, and documentation.
Apply industry‑leading engineering standards with a focus on code quality, consistency, and resilience.
Build and maintain cloud infrastructure using AWS and Infrastructure‑as‑Code tooling (CloudFormation/Terraform).
Own deployment and operational support across development, test, and production environments.
Champion continuous improvement across tooling, processes, and engineering practices.
Partner closely with developers, product owners, scrum masters, and analysts to ensure data enables an exceptional client experience.
Participate fully in agile ceremonies including sprint planning, daily scrums, reviews, and retrospectives.
Significant experience as a data engineer.
Strong proficiency in Python or Java, SQL, cloud environments (preferably AWS).
Hands‑on experience with Kafka and streaming frameworks such as Flink.
Proficiency with data transformation tools (PySpark, Pandas).
Familiarity with data quality frameworks (e.g., Great Expectations).
Experience with graph databases is a plus.
Exposure to building cloud infrastructure via IaC.
Excellent communication skills, able to translate complex topics for technical and non‑technical audiences.
Understanding of agile development; scrum experience preferred.
A continuous learning mindset and willingness to expand both technical and non‑technical skills.
A degree in a STEM field is beneficial but not required.
ES&F is where security engineering, fraud prevention, and advanced data technology converge. You’ll join a mission‑driven group that blends deep technical expertise with real‑world impact:
Purposeful work: Every pipeline, every event stream, and every decisioning workflow contributes directly to protecting investors from financial harm.
Serious scale: Work with high‑volume behavioural, transactional, and event‑driven datasets across multiple markets.
Cutting‑edge tooling: We invest in cloud‑native, real‑time, and streaming architectures - this is not legacy data warehousing.
Strong engineering culture: Thoughtful design, quality code, operational excellence, and continuous improvement are non‑negotiable.
Collaborative environment: Partner daily with security specialists, fraud analysts, architects, and data scientists.
If you want your engineering skills to translate into real‑world protection for millions of people, ES&F offers that rare blend of technical depth and meaningful purpose.

Vanguard Compensation & Benefits Highlights
The following summarizes recurring compensation and benefits themes identified from responses generated by popular LLMs to common candidate questions about Vanguard and has not been reviewed or approved by Vanguard.
-
Retirement Support — Retirement support appears unusually strong through a 401(k) design that includes a match plus an additional employer contribution, which can materially lift long-term total rewards. HSA seeding and an enhanced employer match further strengthen the savings-and-benefits value of the package.
-
Wellbeing & Lifestyle Benefits — Wellbeing and lifestyle support is reinforced by a sizable annual FlexFund stipend that can be applied across many day-to-day categories such as fitness, childcare, and other personal expenses. On-site or virtual clinics and fitness options add practical health and wellness convenience.
-
Affordable Benefits — Healthcare and related benefits are positioned as comparatively affordable via heavily subsidized medical plans and broad coverage options. This affordability can offset moderate base pay for employees who place higher value on out-of-pocket cost reductions.
