Senior Backend Software Engineer — Data Migration Platform

Remote

What You’ll Do

• Build an application that connects to external CRM systems used by acquired agencies, extracts relevant data, and prepares it for migration into Dwelly.
• Work with APIs, exports, files, databases and poorly documented legacy systems.
• Design workflows for cleaning, mapping, normalising, deduplicating, and validating complex CRM data before it enters Dwelly's core platform.
• Build safe import flows with retries, audit logs, dry runs, error handling and manual review where needed.
• Work with entities such as landlords, tenants, properties, tenancies, payments and maintenance records.
• Use LLM APIs pragmatically for schema mapping, data classification, entity matching, exception triage and quality checks.
• Own the platform end to end: architecture, implementation, testing, deployment and production support.
• Work closely with engineering, product, operations and integration teams.

What We’re Looking For

• Strong backend engineering experience with Python.
• Strong practical SQL skills.
• Experience with data migration, ETL/ELT, data processing, system integrations or internal tools.
• Production experience with FastAPI, Django, Flask or similar.
• Experience integrating with external APIs and third-party systems.
• Ability to work with messy, inconsistent or poorly documented datasets.
• Good understanding of data modelling, mapping, validation, deduplication and safe import patterns.
• Good understanding of database transactions, data consistency and production data workflows.
• Experience with Linux, Docker and containerised development.
• Practical experience using AI coding tools and/or LLM APIs.
• Strong ownership mindset and ability to deliver independently under ambiguity.
• Clear communication and ability to work closely with non-engineering stakeholders.

Nice to Have

• Experience with CRM systems, property management systems, fintech, payments or operations platforms.
• Experience with fuzzy matching, entity resolution, confidence scoring or duplicate detection.
• Experience building internal tools for operations, integrations or migration workflows.
• Experience with observability, logging, monitoring and CI/CD.
• Experience testing applications against complex or high-volume datasets.
• Experience with typed languages such as Java, C#, C++, Kotlin, Scala or similar.
• Experience using LLMs for schema mapping, data classification, data extraction or workflow automation.

What Success Looks Like

• Newly acquired agencies can be migrated faster and with fewer manual steps.
• CRM data can be extracted, validated and imported in a repeatable way.
• Data quality issues are detected early and handled safely.
• The migration process becomes more automated, auditable and scalable over time.
• Operations and engineering teams have better visibility and control over migration progress.

Compensation & Benefits

• Fully remote role.
• Competitive compensation based on experience and impact.
• Opportunity to work on high-leverage automation systems at the intersection of backend engineering, applied ML, data and real operational workflows.
• Competitive salary with the potential for equity options based on performance, recognising exceptional contributions to our integration success.
