API Data Migrations Specialist
Data Migration Engineer – Hybrid / Remote (UK-based)
£35,000 - £45,000 | Engineering Team
About Our Client
Our client is one of the Financial Times’ fastest-growing software companies in Europe and a Sunday Times Best Place to Work. As they scale, they're seeking a Data Migration Engineer to take ownership of migrating customer data onto a platform used by thousands of users—every single working day.
About the Role
You’ll be responsible for:
- Owning day-to-day migration delivery, ensuring complex customer data moves into the platform safely, accurately and reliably—without the dreaded "contact lists mysteriously vanishing*" scenario.
- Working with migration APIs to integrate diverse external systems, transforming and validating data while navigating inconsistencies.
- Starting with guidance from senior engineers in building new migrations, progressing to self-sufficient, high-trust delivery.
- Joining customer-facing calls when needed to explain technical challenges and providing feedback to improve the migration architecture.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You’ll Need
Must-Haves
- Strong Python skills (this is a backend-focused role)
- Solid AWS experience, particularly:
- DynamoDB
- S3
- Containers and ECS (Elastic Container Service)
- Hands-on experience with:
- Migration APIs and endpoint-based integrations
- Reading unfamiliar external system documentation
- Experience with CRM platforms (or recruitment/operational systems) to quickly grasp source data structures
- Proficiency in SQL
Nice-to-Haves
- Familiarity with AWS Lambda and stream technologies
- Basic frontend knowledge (e.g., jQuery or Svelte)
- Experience with FTP/SFTP-based export retrieval
- Customer-facing technical or integration-heavy experience
Who You Are
The ideal candidate is:
- Detail-oriented, diligent, and quality-focused—the kind of person who alphabetises for fun and would rather validate data twice than explain a 3,000-record candidate data loss to a customer.
- Comfortable with structured, process-driven work but knows when to:
- Flag risks
- Escalate issues
- Request reviews
- A clear communicator who:
- Manages deadlines effectively
- Offers practical, solution-driven solutions instead of obstruction
