About the job

• Consumer Bureau - Role – Senior Software Engineer – Python & AWS Creditsafe are expanding their Consumer Bureau team, an exciting new project aiming to have us enter the Consumer Credit Bureau space in the United Kingdom and eventually become a fully-fledged Consumer Reporting Agency. We’re looking for a Senior Engineer experienced in developing cloud-native software systems. WHO WE ARE Privately owned and independently minded, at Creditsafe, we are guided by values of customer-focus, trust, respect, and a willingness to try new things. For over 20 years, these values have shaped a culture of growth, innovation, and support, where our team members build successful, long-term careers. With a diverse team spread across 25 offices in 14 countries, we value collaboration, learning, and problem-solving together. We have been featured twice in The Sunday Times' '100 Best Companies to Work For' and continue to prioritize well-being, career growth, and inclusion. Our continued success has made us the most used business data provider in the world and one of the industry’s strongest growing business intelligence providers. Today Creditsafe has 23 offices across 3 continents serving 110,000 customers from SMEs to enterprise businesses. THE TEAM This opportunity is to join an Agile team of Software, Data and Quality engineers who are responsible for two - one productionized and one upcoming – big data projects. These projects process hundreds of GB a day in massive ELTL ingest, person-centric matching, and sub-second-serving batch and near-real-time processes. YOUR ROLE As a Senior SE, you'd play a key role in developing and enhancing our Data Ingestion, orchestration, transformation and deployment layers, owning batch and near-real-time serving via API and backend processes. Bureau is a greenfield project in its infancy with a long term, ambitious roadmap and direct, measurable client reach and satisfaction. This is a hybrid position, requiring attendance in the office for 50% of the working week, in line with our hybrid work policy. WHAT YOU'LL OWN Cross-team decisions. Partner with two or three engineering teams, Product, and Data Analytics to make the right technical trade-offs — especially the ones no single team can make alone.
• Quality of the whole. Reliability, performance, cost and security for your domain. When an incident touches your area, you’re part of the postmortem.
• Engineering standards. Set the bar for design reviews, API contracts, testing and operability — and teach it, so it sticks.
• Hands-on work. We expect you to ship code — typically the hard bits, the de-risking prototypes, and the reference implementations others build on.
• Mentorship. Grow other engineers into the next Seniors. Collaborate with Engineering Managers and Data Experts on technical direction. Be generous with your time.
• WHAT YOU BRING Must-haves Deep experience building and running production systems in Python on AWS — typically 8+ years of engineering, with at least a couple of those operating at a Senior/Lead scope.
• A track record of leading systems, not just features. You can point to platforms or services you designed whose decisions still hold up under load, change and time.
• Strong judgement on trade-offs. Cost vs. latency, build vs. buy, consistency vs. availability, velocity vs. debt — and you can explain your reasoning in a room of non-engineers.
• Demonstrable technical influence in your teams. RFCs, guilds, tech-demos, shared libraries, architecture forums — something that shows your reach.
• A mentoring habit. Named engineers whose careers moved because of your input. You already enjoy this work.
• Excellent written communication. Your docs, RFCs and postmortems teach people things. This matters as much as your code.

Nice to have • Deep AWS data-platform chops: Glue, Athena, MWAA, ECS/EKS, Iceberg/Parquet, lakehouse patterns. • High-throughput serverless design with auditability and exactly-once semantics. • Financial, credit or regulated-data background.
