О компании и продукте

• Dwelly is building the AI operating system for residential lettings. Its growing network of agencies provides its AI with real-world data, continuous feedback, and control over complete workflows, making exceptional service the standard for landlords and tenants. Today, Dwelly operates more than 15,000 properties and $470 million in GMV, making it one of the UK’s ten largest lettings operators. The company has raised $263 million.
• We’re a fast-growing, product-focused company, backed by top-tier investors and led by a team with deep experience in real estate, technology, and operations.
• We are looking for a Senior Backend Engineer to build Dwelly’s internal Data Migration Platform — a system that connects to legacy CRMs, extracts and validates agency data, handles exceptions, and imports it safely into Dwelly’s core platform.
• This role goes beyond standard backend API development. You will build production systems around messy CRM data, external integrations, validation logic, migration workflows and operational edge cases.

Задачи

• 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

Требования

• 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

Будет плюсом

• 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

Условия

• 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
• What is it like being a Dwell-er?
• Feel free to check out Dwelly Core Principles . That’s about what we believe in, how we operate and make decisions
• What we offer is not a fancy office or a static workplace
• Instead, this is about solving one of the world’s most complex problems in the largest consumer industry in the world: residential rentals
• More than 30% of households live in rental homes — over 5 million in the UK and more than 100 million across the EU and US
• Our mission is to improve that experience through technology, automation and operational excellence
• This is about disrupting one of the largest and most antiquated industries in the world with one of the strongest operational and technical teams in the UK and Europe
• We work hard, and we aim for extremely ambitious results
• We want people to be proud of what they’ve built and to one day look back and say: “Hell yeah, that was me that did it.”
